2
3	<	1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4	<	with a Firebrid 3 client library.
3	>	1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
4	>	with later versions of fpc - later than 3.2.2.
5
6	<	2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7	<	If a client library path is not explicitly provided and the FIREBIRD environment
8	<	variable is set then the directory given by this variable and any 'lib' subdirectory
9	<	are searched for the Firebird client library. Only if none is found, is the default
10	<	client library used.
6	>	2. IBUpdateSQL. update internal queries if parent dataset database changed.
7
8	<	3.  IUtil.FormatStatus now used to format error messages when using new API
8	>	3. IBUpdateSQL: Do not prepare an empty internal query.
9
10	<	4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
10	>	4. IBBufferedCursors: avoid range error when max field no. is > fields.count
11
12	<	5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17	<	returned using GetAsString and the string codepage is UTF8, the string is truncated so
18	<	that the byte length corresponds to the number of characters specified for the column.
19	<	SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20	<	correct behaviour but may affect some implementations that relied upon automatic
21	<	trimming of trailing white space.
12	>	5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
13
14	<	6.  New IFirebirdAPI Calls:
24	<	function GetClientMajor: integer;
25	<	function GetClientMinor: integer;
14	>	IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
15
16	+	1. Maintenance update of 2.6.0. This version is still at beta.
17
18	<	FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
18	>	2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
19	>	See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
20
21	<	1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
22	<	case sensitive
21	>	3. ibxscript: When parsing a store procedure or function with a variable name
22	>	enclosed in doublequotes, the double quotes are no longer removed.
23
24	<	2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
24	>	IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
25
26	<	3. New API Calls:
27	<	IColumnMetaData.GetStatement
28	<	IColumnMetaData.GetTransaction
29	<	ISQLData.GetStrLength
39	<	IResults.GetStatement
40	<	IAttachment.OpenBlob (using Blob metadata)
41	<	IAttachment.OpenArray (using array metadata)
26	>	NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
27	>	AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
28	>	BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
29	>	ISSUES TO support@mwasoftware.co.uk
30
31	<	4. FBMessages: removal of unused messages
31	>	1. Complete rewrite of internal buffer management in order to improve performance
32	>	and maintainability. Highlights:
33
34	<	5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
34	>	* Extending the size of the buffer pool no longer has to copy the entire record
35	>	cache. Instead, a new extent is simply added to the buffer pool.
36	>	* A memory to memory copy of each display buffer now is avoided when scolling the
37	>	dataset.
38	>	* A separate set of buffers is now used for calculated fields. This avoids
39	>	having to keep copies of calculated field values in the buffer cache.
40	>	* Compact bitmaps are used to record null status and need to refresh in each
41	>	buffer.
42	>	* Display buffer type changed from PChar to TRecordBuffer in line with change of
43	>	buffer type in FCL-DB.
44
45	<	6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
45	>	2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
46	>	to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
47
48	<	FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
48	>	3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
49	>	If either or both of these flags are set at design time (using the fields editor)
50	>	then this forces a row refresh on respectively insert or update, or both, when the
51	>	corresponding field is not present in an SQL RETURNING clause.
52
53	<	1. Fix a problem with the SQL parameter parser that failed to recognise parameters
54	<	where the second character of the parameter name is a numeric.
53	>	4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
54	>	maintainability and readability and to add identification of primary key fields.
55
56	<	2. New method for IAttachment: procedure getFBVersion(version: TStrings);
57	<	This returns the isc_version connection information as one or more lines.
58	<	This is the same information as returned by isql with the -z option.
56	>	5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
57	>	as a refresh of the current row. However, this is different behaviour to that described
58	>	in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
59	>	the dataset from the underlying database, and attempts to reposition the cursor on
60	>	the same record as it was". IBX now complies with the FPC definition of Refresh.
61
62	<	3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
63	<	is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
64	<	compiler option then the Firebird 3 API is no longer compiled in.
62	>	6. A progammatic Row Refresh should no longer be required.
63	>	Use Insert/Update... returning to refresh any fields that may change following an
64	>	insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
65	>	on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
66	>	for the field at Design Time to force a row refresh if not in the returning clause.
67
68	<	4. IColumnMetaData: new method.
68	>	7. It should now be possible to insert a row into an empty unidirectional dataset.
69
70	<	TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
71	<	dfDateTime,   {SQL DATETIME}
72	<	dfTime);
70	>	8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
71	>	This gives the number of buffers in the initial block for the buffer pool in
72	>	bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
73	>	in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
74	>	for small datasets.
75
76	<	function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
76	>	IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
77
78	<	This returns the max. number of characters returned by the "AsString" method
71	<	when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
78	>	1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
79
80	<	5. Additional argument for IAttachment.PrepareWithNamedParameters -
74	<	CaseSensitiveParams: boolean = false
80	>	2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
81
82	<	If this argument is set to true then SQL parameter names are assumed to be case
77	<	sensitive and must be referenced (using ISQLParams.ByName) using the case
78	<	sensitive name.
82	>	3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
83
84	<	6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81	<	is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82	<	.AsCurrency) and then subsequently to update the value to a non-numeric string
83	<	using .AsString.
84	>	IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
85
86	+	1. TIBTransaction: new properties
87	+	property TransactionID: integer read GetTransactionID;
88	+	property IsReadOnly: boolean read GetIsReadOnly;
89	+	{published}
90	+	property TransactionName: string read FTransactionName write SetTransactionName;
91
92	+	2. IBCustomDataset: per row blob and array buffer cached clear before processing
93	+	Insert or Update...Returning. This allows blobs and arrays to be returned
94	+	by the statement.
95
96	<	FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
96	>	3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
97
98	<	1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
98	>	4. TransactionName initialised to a newly generated GUID if empty.
99
100	<	2. Restrict IsMultiThread check to Unix only for compatibility with
101	<	https://bugs.freepascal.org/view.php?id=30535
100	>	5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
101	>	for the fbintf package's journaling capability. TIBJournal is used to set the
102	>	file path and filename for the journal file and to Enabled (start journaling) and
103	>	disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
104	>	more information, and comments in IBJournal.pas.
105
106	<	3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95	<	named parameters and is intended to avoid problems with (e.g.) Execute Block
96	<	and processing internal parameters as statement parameters.
106	>	6. TIBDatabase.InternalTransaction is now a read only transaction.
107
108	<	4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
109	<	or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
108	>	7. Bug fix: blob id no longer set to null on update when blob has not been
109	>	retrieved.
110
111	<	5. New function added to IB.pas
111	>	8. Row auto refreshed on update/insert if blob or array field updated and field
112	>	not in a returning clause.
113
114	<	function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
114	>	9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
115	>	buffer overhead and avoids problem when refresh query has a different column
116	>	count to select query i.e. incorrectly changing number of columns.
117
118	<	This allows a Firebird Library to be loaded from an explicit path. use the
106	<	IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107	<	the library. It is possible to load Firebird libraries from different locations
108	<	simultaneously, each with a distinct IFirebirdAPI.
118	>	10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
119
120	<	FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
120	>	11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
121	>	string. Note that the Version property returns an InterBase compatible version string.
122
123	<	1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113	<	program compiled with -CR command line switch.
123	>	12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
124
125	<	2. IServiceManager additions (informational):
116	<	function getProtocol: TProtocol;
117	<	function getPortNo: AnsiString;
125	>	IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
126
127	<	3. IServiceManager improved error handling. Interfaces changed:
128	<	function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
129	<	function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122	<	function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
127	>	1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
128	>	This is for compatibility with Firebird 5 where Update...Returning can return
129	>	a cursor.
130
131	<	4. IAttachment addition (informational)
125	<	function GetSecurityDatabase: AnsiString;
131	>	IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
132
133	<	5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
134	<	thus now returns accumulated stats for a select statement from opening a cursor
135	<	up to the last fetch.
133	>	1. Add try-..except check when initially loading library in IDE. This should
134	>	ensure that IDE continues to load even when a failure occurs in IBX load
135	>	library.
136
137	<	6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
138	<	the problem.
137	>	2. IBXScript: now recognises a CASE...END block within a stored procedure and
138	>	hence will correctly detect end of the outer containing block when the block
139	>	contains a SELECT ... CASE ... END construct.
140
141	<	7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135	<	replaces deprecated "comp" type.
141	>	3. IBExtract: some further tidying up to remove extraneous white space.
142
143	<	10. Testsuite Test10 updated to include thread synchronisation for event reporting.
143	>	4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
144	>	errors when extra elements are added to DB.TFieldType.
145
146	<	11. URL Connection Strings: inet4 and inet6 now recognised.
146	>	5. IBUpdate: updated to reflect changes to ISQLParam.
147
148	<	12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
148	>	6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
149
150	<	13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
150	>	7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
151
152	+	8. IBSQL: Support for scrollable cursors added (note: local databases only)
153
154	<	FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
154	>	IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
155
156	<	1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
156	>	1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
157	>	exception of those defined to be one byte wide e.g. DBImplementationNo.
158
159	<	2. IAttachment: add two new methods
151	<	function HasDefaultCharSet: boolean;
152	<	function GetDefaultCharSetID: integer;
159	>	2. TIBSQL: Batch Update/Insert support added.
160
161	<	These return, respectively, true if a connection default character set was
162	<	specified and the character set id of the connection default character set.
163	<	The DefaultCharSetID is cached when the connection is opened and hence does not
164	<	require a database lookup.
161	>	3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
162	>	is no longer automatically converted to upper case when it is syntactically a
163	>	SQL Identifier. This is to support the use of stored procedures defined e.g.
164	>	as CREATE PROCEDURE "iCASE".
165
166	<	3. Avoid exception when a text blob is a stored procedure parameter.
166	>	There could be a backwards compatibility issue when the StoredProcName was entered
167	>	manually at design time. That is not selected from the drop down list. If the
168	>	StoredProcName is entered in mixed case and the procedure was declared e.g. as
169	>	CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
170	>	ensure that the value of the StoredProcName is all upper case, unless it was
171	>	declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
172	>	quotes).
173
174	<	4. Update test suite to include a test for a stored proc returning a text blob.
174	>	Note that when a stored procedure name was declared delimited in double quotes,
175	>	as in the first example above, the value of the StoredProcName property must not
176	>	include the delimiters (double quotes).
177
178	<	5. IAttachment: add
179	<	function GetRemoteProtocol: AnsiString;
165	<	function GetODSMajorVersion: integer;
166	<	function GetODSMinorVersion: integer;
167	<	function GetAuthenticationMethod: AnsiString;
178	>	4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
179	>	upgrade.conf was not found. This replaces silently ignoring the problem.
180
181	<	These results are cached when the connection is opened and hence do not
182	<	require a database lookup.
181	>	5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
182	>	'Version.%.3d' and is used to generate the section header names (for a given
183	>	version no.) in the upgrade.conf file.
184
185	<	6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173	<	connect string used to create/connect to the database.
185	>	IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
186
187	<	7. IAttachment: Create Database using SQL statement. The username and password
188	<	are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177	<	It is now possible to use IAttachment disconnect/connect to reconnect to
178	<	a database for which the initial connection was established by a create
179	<	database sql statement. Available in FPC only.
187	>	1. -c command line option added to fbsql example program. Used to set connection
188	>	character set.
189
190	<	8. Update Test 1 to test 5, 6 and 7 above.
190	>	IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
191
192	<	9. IBUtils code tidy up.
192	>	1. Firebird 4 support added.
193
194	<	10. Parameter Block interfaces "find" method. As documented, this should have
195	<	returned a nil interface when the item could not be found. Instead, an empty
187	<	interface item was returned. "Find" now works as documented and will return
188	<	a nil interface if the item cannot be found.
194	>	2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
195	>	extended precision NUMERIC fields are supported.
196
197	<	11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
197	>	3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
198
199	<	12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
200	<	requests with additional parameters. This is to enable support for fb_info_page_contents
194	<	(return of page contents). Response to fb_info_page_contents returned as
195	<	a string with code page CP_NONE.
199	>	4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
200	>	and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
201
202	<	13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
203	<	test suite updated.
202	>	5. IBExtract now supports FB4 enhancements:
203	>	- new data types as above
204	>	- Identity column extensions
205	>	- Default user role
206	>	- SQL Security clause for Database, Tables, Procedures, Functions and Triggers
207	>	- Internal Functions
208
209	<	14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201	<	a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
209	>	6. IBExtract: new event: OnExtractLines.
210
211	<	15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204	<	An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205	<	default connection port to be specified.
211	>	7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
212
213	<	FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
213	>	8. IBXServices: Server version no. parsing now allows any letter before major version number
214	>	and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
215
216	<	1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
217	<	Scale is no longer ignored.
216	>	9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
217	>	format for rendering a time zone.
218
219	<	2. Fix issues with setting SQL Param values using SetAsString with Date values
220	<	not in locale format but which are recognised by Firebird. Date values that
214	<	cannot be converted to a string using Pascal library are now passed through
215	<	to Firebird as Text Strings.
219	>	10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
220	>	to convert TIME WITH TIME ZONE data type values to and from GMT.
221
222	<	3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
223	<	UTF8 and not UNICODE_FSS.
222	>	11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
223	>	IIBGUIInterface and IIBTimerInf respectively.
224
225	<	4. Charset ID problem. When using Firebird 3, with no default database character set
226	<	and a column has a non-default collation specified, an incorrect character set
222	<	id was being reported that could result in a 'division by zero' error when
223	<	used by IBX. This has now been fixed.
225	>	12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
226	>	now accessible as properties of TIBDatabase and TIBTransaction respectively.
227
228	<	5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
229	<	CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
230	<	the character sets supported can be updated on a per database basis. That is
228	<	it is possible to add a (Firebird) user defined character set to a database.
228	>	13. String Fields: when a fixed character with (CHAR) field is returned, it is now
229	>	truncated to its fixed character width rather than being right padded with
230	>	white space to the maximum data size.
231
232	<	6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
233	<	set supported by Firebird with the API.
232	>	14. TIBTable.Empty table. In additional to deleting all records in the underlying
233	>	table, the internal buffers are now also flushed ensuring that the TIBTable is
234	>	also empty.
235
236	<	7. Add missing isc_info_db_read_only to list of decoded Database Information items
234	<	in FBOutputBlock.pas and update test suite to include this item.
236	>	15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
237
238	<	8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
238	>	16. TIBXControlService descendents: DatabaseName may now be set using a database
239	>	connect string. The database name is extracted from the connect string.
240
241	<	9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239	<	library or finding it by disk location, the PATH environment variable is now also set to
240	<	include the FIREBIRD directory. This is to ensure that the correct dlls in the
241	<	firebird client library dependencies are loaded.
241	>	17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
242
243	<	10. Testsuite: Ensure consistent UTF-8 output on Windows console.
243	>	18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
244
245	<	11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
245	>	19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
246	>	not being present as required.
247
248	<	12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248	>	20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
249	>	version that can be customised to work with other database drivers.
250
251	<	13. FB30Statement: A check has been added to ensure that all SQL Parameters
252	<	have been given a value (including NULL). Previously, failing to set the
251	<	value of an SQL Parameter could give rise to unpredictable results or
252	<	an SQLDA error.
251	>	21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
252	>	unnecessary CR at end of line on Unix platforms.
253
254	<	14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
254	>	22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
255	>	seconds in order to reduce risk of message loss.
256
257	<	15. FBAttachment: Avoid string reference count error when processing an Ansistring
258	<	parameter in an array of const passed to IAttachment.OpenCursor, etc.
257	>	23. ISQLMonitor: read and write count statistics now available via:
258	>	property TIBSQLMonitor.ReadCount;
259	>	IIBSQLMonitorHook.GetWriteCount: integer;
260
261	<	16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260	<	of const passed to IAttachment.OpenCursor, etc.
261	>	24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

265	<	FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
265	>	1.  TIBStringField: when a string value is read from a dataset buffer, if the
266	>	number of UTF8 characters exceeds the string size then string is truncated
267	>	to the maximum string size. This is  usually a problem with fixed width columns
268	>	right padded with white space.
269
270	<	1. Change syntax to Mode Delphi
270	>	2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
271	>	If SQLFiltered is set then when a dataset is opened, each line in the
272	>	SQLFilterParams property is assumed to be a SQL condition clause and
273	>	ANDed into the Where clause of the SQL Select statement provided as a
274	>	dataset property. Each such SQL condition thus acts as an additional filter
275	>	on the dataset.
276
277	<	2. Change all uses of string type to explicit AnsiString in order to ensure
278	<	compatibility between Delphi and FPC.
277	>	3.  The Filtered property inherited from TDataset is no longer used for SQL (server
278	>	side filters).
279
280	<	3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
281	<	defined for each interface.
280	>	4. IBLookupComboEditBox: Selection should no longer reset to start of text when
281	>	text matches complete entry.
282
283	<	4. Generics syntax variations for Delphi added
283	>	5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
284	>	dataset are active (avoids risk of access violation if master is inactive)
285
286	<	5. PChar replaced with PByte expect where an actual string is being referenced,
276	<	where PAnsiChar is used instead.
286	>	6. TIBEvents: Registered property can now be set at design time even if database not open
287
288	<	6. Review of type definitions in IBExternals to ensure Delphi compatibility
288	>	7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
289	>	This should prevent "spillover" of events between sessions.
290
291	<	7. Testsuite updated for Delphi
291	>	8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
292	>	This should ensure that the internal buffer is set up correctly and avoids
293	>	a duplicate initial row.

295	<	FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
295	>	9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
296	>	That is, the DataSize should be the field size * character set width. The
297	>	value returned by DataSize is now the same as the Dataset buffer size reserved
298	>	for the field.
299
300	<	1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285	<	large blobs and the FB3 API.
300	>	10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
301
302	<	2. Update Event Handling algorithm to avoid looping due to recreation of the
303	<	event block.
302	>	11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
303	>	and vice-versa. This may result in an exception being raised (correctly) for
304	>	older programs when using dataset fields added to a form and the database has been
305	>	upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
306	>	In such cases, the field needs to be deleted in the IDE fields editor and then
307	>	added back in.
308
309	<	3. Avoid invalid XSQLDA error when the only parameter is updated to null
309	>	12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
310	>	false if query contains only white space and not just empty.
311
312	<	4. Array Handling: fix problem with text arrays with character set none. When the
313	<	DB connection has a default character set (e.g. UTF8), an error is raised by
314	<	Firebird if the space allocated is not enough to allow for transliteration, even
295	<	though it is not required for character set none.
312	>	12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
313	>	should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
314	>	is cancelled.
315
316	<	5. IBUtils: List of reserved words brought up-to-date
316	>	13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
317	>	called on a null field.
318
319	<	6. Add ISQL style performance statistics collection to IStatement
319	>	14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
320	>	results in an empty dataTC86                Client side Filtered Dataset    1       X
321	>	set.
322
323	<	7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
324	<	CREATE DATABASE statement.
323	>	15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
324	>	a cached update is applied and an exception is raised.
325
326	<	8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
305	<	an array dimension is not mistaken for a named parameter prefix.
326	>	16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
327
328	<	9. Trim function no longer applied to result of GetAsString for SQL_TEXT
308	<	when Character set is octets. Avoids loss of non printable characters at start of string.
328	>	17. Console Mode Local Database support: backup/restore should now work correctly.
329
330	<	10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
331	<	statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312	<	to enable stats gathering.
330	>	18. Local Database Support: if an upgrade fails, a downgrade is now performed if
331	>	possible and an exception raised.
332
333	<	11. API Version information added as constants to IB.pas
333	>	19. MinimumVersionNo added to Local Database Support. Database will not open if

346
347	+	4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
348	+
349	+	5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
350	+	only enclosed in double quotes in SQL dialect 3 and when it needs to be.
351	+
352	+	6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
353	+	validated. If no match is found in the list of field names and the database has
354	+	been opened in SQL Dialect 3, then the ListField Name is converted to upper case
355	+	if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
356	+
357	+	7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
358	+	with fpc 3.2.
359	+
360	+	IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
361	+
362	+
363	+	1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
364	+	and is used to override the default settings in the client side "firebird.conf" This
365	+	includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
366	+	Each line of the string list should be a setting in the same format as "firebird.conf".
367	+	For example "WireCompression = true" in order to request wire compression on the client side.
368	+
369	+	Note: explicit settings in the client side "firebird.conf" appear to take precedence
370	+	over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
371	+	also require a compatible setting in the server side "firebird.conf". For example
372	+	"WireCompression = true" must also be set in the server's "firebird.conf" for wire
373	+	compression to be used.
374	+
375	+	Whether or not WireCompression or WireCrypt are in use can be checked using the information
376	+	returned with the Client/Server protocol version. See ibx/examples/dbadmin and
377	+	ibx/examples/dbinfo for examples of how to display this information.
378	+
379	+	2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
380	+	is a "convenience" property. If set the "WireCompression=true" is added to the
381	+	ConfigOverrides. If unchecked then this setting is removed.
382	+
383	+	3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
384	+	not "INT64".
385	+
386	+	4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
387	+	These are:
388	+	property TimestampFormat: string;
389	+	property DateFormat: string;
390	+	property TimeFormat: string;
391	+
392	+	Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
393	+	DATETIME and TIME. The format strings use the standard FPC date/time format
394	+	characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
395	+
396	+	If any of the above properties are set to an empty string, then the locale default
397	+	is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
398	+	locale default is extended by appending '.zzz' to include milliseconds.
399	+
400	+	TIBCSVDataOut by default sets these properties to the empty string, while the other
401	+	two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
402	+
403	+	5. New published property for TIBCSVDataOut:
404	+	property QuoteStrings: boolean (default true)
405	+
406	+	If false then strings are unquoted, otherwise, the QuoteChar property value is
407	+	used to delimit each and every string in the output.
408	+
409	+	6. New published properties for TIBCSVDataOut:
410	+	property FieldSeparator: string;
411	+	property HeaderSeparator: string;
412	+
413	+	Respectively, these provide the separator character(s) used to separate fields
414	+	in data and header rows. Both default to ','.
415	+
416	+	7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
417	+	TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
418	+	property OnFormatTextString;
419	+
420	+	This event handler can be used to process text strings before they are included
421	+	in the output e.g. to replace unprintable characters with alternative strings.
422	+	This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
423	+
424	+	8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
425	+	Uses "FindParam" if in order to find out if a parameter with a given name exists
426	+	and without raising and exception if it does not.
427	+
428	+	9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
429	+	consistency with SQL queries.
430	+
431	+	10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
432	+	When true, SQL statement parameter names are parsed case sensitive. Note for
433	+	TIBDataSet only applies to Select query.
434	+
435	+	11. IBEvents: removing a TIBEvent component from a form should no longer result in
436	+	an IDE exception.
437	+
438	+	12. LocalDBSupport: initial database creation should now work correctly
439	+	when the schema source is an sql file.
440	+
441	+	13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
442	+	when defined, this handler will be called by the internal TIBXScript during
443	+	initial database creation when the schema source is an sql file and may be used
444	+	to provide a visual indication of progress in console mode.
445	+
446	+	14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
447	+	to true while a new local database is being created and its schema populated.
448	+	Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
449	+	when the database is disconnected/connected during the create DB procedure.
450	+
451	+	15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
452	+	are now always ignored and replaced by the user name and password provided as
453	+	the login parameters for the TIBDatabase referenced from the TIBXScript. The
454	+	IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
455	+	completely ignored if this property is true.
456	+
457	+	16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
458	+	to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
459	+	ImageIndex and SelectImageIndex values on AddNode.
460	+
461	+	17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
462	+	read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
463	+	the same database connection.
464	+
465	+	18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
466	+	if provided, this should be an conditional SQL expression suitable for
467	+	including in an SQL Select statement "where" clause. If non-empty and the
468	+	"Filtered" property is true then the SQL expression provided as the value of
469	+	the "Filter" property is "ANDed" with any existing condition statement
470	+	in the SQL statement's "Where" clause.
471	+
472	+	If the "Filter" property is set at run time, the "Filtered" property is true
473	+	and the dataset is already open, then the dataset is closed and re-opened automatically.
474	+
475	+	The "Filter" condition may include IBX style parameters. In which case, their
476	+	value must be set by the dataset's "OnBeforeOpen" event handler.
477	+
478	+	This is a public property for TIBDataSet and TIBQuery query and intended for
479	+	use at run time.
480	+
481	+	Note: The property is a published property of TIBTable. The TIBTable functionality
482	+	is unaffected by this change.
483	+
484	+	IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
485	+
486	+	1. Remove need to check for IsMultiThread by providing access to GUI timers via
487	+	IBGUIInterface. Note: master/detail delay timer does not apply to console
488	+	mode apps.
489	+
490	+	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
491	+	statement. This avoids problems if "Execute Block" is used as the Query.
492	+
493	+	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
494	+	internal SQL tokeniser routines.
495	+
496	+	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
497	+	as a select statement, with or without CTEs.
498	+
499	+	5. IBSQLParser: parser now recognises the "ROWS" clause.
500	+
501	+	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
502	+	internal SQL tokeniser routines.
503	+
504	+	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
505	+	being raised for valid set statements processed by a data formatter.
506	+
507	+	8. New published property for TIBDatabase and TIBXServicesConnection. This is
508	+	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
509	+	the path of the Firebird Library used by the database/services connection.
510	+
511	+	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
512	+	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
513	+	services connection.
514	+
515	+	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
516	+	or param name is not a valid SQL identifier.
517	+
518	+	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
519	+	view of whether the text box should be editable when no DataSource is specified.
520	+	TIBLookupComboEditBox has been updated to workaround this problem. As long as
521	+	ReadOnly is false, the text box is editable when no DataSource is specified.
522	+
523	+	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
524	+	the FBLIB environment variable. If you do not want to permit this then you
525	+	must modify the Register procedure in the design/IBDBReg.pas unit to remove
526	+	this setting.

534	+
535	+	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
536	+	all previous copies of the IBX source code tree before installing this release.
537	+
538	+	The IBX packages used by most users have not changed, with one exception. The
539	+	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
540	+	to use the IBServices unit in your applications, please add the iblegacyServices
541	+	to the list of dependencies. To do this, open the Project Inspector and select
542	+	Add->New Requirement and select "ibLegacyServices" from the list of available
543	+	packages.
544	+
545	+	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
546	+	the IBServices unit providing what is intended to be a clearer and easier to
547	+	use set of IB Services components. See Chapter 10 of the IBX User Guide for
548	+	more information and the guide to "Firebird Service Management Using IBX".
549	+	As indicated above, the legacy services components are still available and
550	+	provided in a separate package. There is no need to update working applications
551	+	using the older versions except for an additional package dependency.
552	+
553	+	2. The IBX packages and source code tree have been re-organised in an attempt to
554	+	finally get rid of the "duplicate ppu" warnings. This re-organisation should
555	+	not affect existing users. Section 2.3 of the IBX User Guide describes the
556	+	new set of IBX packages.
557	+
558	+	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
559	+	updated to use the new Services API components.
560	+
561	+	4. The iblocal package has been updated to use the new Services API components.
562	+
563	+	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
564	+	TIBXSecurityService. It had been wrongly classified in the previous version
565	+	as a per database configuration item. It is global to a server and hence
566	+	correctly positioned as part of the Security Package. In the DBAdmin example,
567	+	the setting has moved to the mappings page.
568	+
569	+	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
570	+	are ignored.
571	+
572	+	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
573	+	closed before the database is dropped. Before and After Disconnect event handlers
574	+	are also fired.
575	+
576	+	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
577	+	is started and not just the first time.
578	+
579	+	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
580	+	depenendency with comp type.
581	+
582	+	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
583	+
584	+	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
585	+	then this is recognised and not ignored.
586	+
587	+	12. TIBDataSet, TIBQuery, TIBTable: additions:
588	+	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
589	+	function GetPerfStatistics(var stats: TPerfCounters): boolean;
590	+	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
591	+
592	+	GetRowsAffected returns the affected row counts from the last insert/update/delete
593	+	if EnableStatistics = true then GetPerfStatistics returns the current stats
594	+	counters for the select query. Note: stats accumulate after each fetch from
595	+	the database. To get total query cost after open, call the "Last" method
596	+	and then GetPerfStatistics.
597	+
598	+	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
599	+
600	+	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
601	+	in parenthesises.
602	+
603	+	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
604	+	SQL identifiers are always delimited by double quotes. If false, then they are
605	+	only delimited if the identifier is a reserved word, contains lower case or special
606	+	characters. Set this property to true to retain previous behaviour.
607	+
608	+	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
609	+	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
610	+
611	+	16. TIBDataSet, TIBQuery, TIBTable: addition:
612	+	property MasterDetailDelay: integer {defaults to zero}
613	+
614	+	When non-zero and the dataset is a detail table referencing a master table
615	+	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
616	+	then a synchronisation delay is added (in milliseconds) between the master
617	+	row changing and the detail dataset being re-opened. If the master dataset
618	+	is scrolled before the delay expires then the delay is reset. This can be used
619	+	to avoid performance overheads when scrolling through a large master dataset.
620	+
621	+	Note: uses fptimer and hence requires a thread manager. Under Linux the
622	+	chreads unit must be included in your project. TTimer is not used in order
623	+	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
624	+
625	+	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
626	+	with Extract Option eoDatabase.
627	+
628	+	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
629	+	When a deLayoutChanged event is reported on the ListSource dataset, the
630	+	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
631	+	relationship with the control's datasource (master).
632	+
633	+	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
634	+
635	+	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
636	+	stubs. Pedantic fix really, as procedures output in dependency order anyway.
637	+
638	+	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
639	+	DDL (Firebird 3 and later only).
640	+
641	+	22. TIBLookupComboBox Autocomplete Fixes:
642	+	i. Only appended text is now selected after autocomplete.
643	+	ii. Uppercase keys no longer ignored for autocomplete.
644	+	iii. Retain Prefix case is now honoured correctly.
645	+	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
646	+	before autocomplete performed. i.e. behaviour now the same as when
647	+	no DataSource assigned.
648	+
649	+	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
650	+	between SQL statements.
651	+
652	+	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
653	+	ObjectNames are converted to upper case before matching against metadata object
654	+	names, unless the objectname is delimited by double quotes, in which case, the
655	+	double quotes are removed and the remaining string is used (unmodified) to match
656	+	against the metadata object name.
657	+
658	+	If true then the ObjectName is used as is without modification and matched
659	+	against the metadata object name. No attempt is made to remove double quotes.
660	+
661	+	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
662	+	with eoTrigger, these extract types can be used to select only Database Triggers,
663	+	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
664	+
665	+	26. TIBXScript: If an exception occurs during the processing of a statement, the
666	+	statement separate character is now reset to the default (';').
667	+
668	+	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
669	+
670	+	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
671	+	a commit or reconnect statement and instead activated only when next SQL statement
672	+	is executed.
673	+
674	+	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
675	+
676	+	30. TIBXScript: case insensitive regex now used when matching statements instead of
677	+	converting statement to upper case.
678	+
679	+	31. TIBExtract: metadata comments now supported. New published property
680	+	IncludeMetaDataComments (default true). If true then metadata comments included
681	+	in extracted DDL. New Extract Object member eoComments. This may be used with
682	+	ExtractObject method to list all metadata comments.
683	+
684	+	32. TIBExtract: ListObjectNames method added.
685	+
686	+	33. Updated Database component editor to support additional connection string
687	+	types.
688	+
689	+	IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
690	+
691	+	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
692	+	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
693	+	RELEASE.
694	+
695	+	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
696	+
697	+	1. IBExtract: Identity columns - add additional check for null column for generator name.
698	+
699	+	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
700	+	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
701	+	information). However, this is also a very useful mechanism for returning updated computed by
702	+	column values. Values returned as a result of executing an Insert or Update statement
703	+	replace existing values in the current row for each corresponding column.
704	+
705	+	Previously, if a dataset's select query included read only (computed by) fields then
706	+	an automatic row refresh was performed after an insert or update query had been processed,
707	+	irrespective of the setting of the "ForcedUpdates" property. This has changed such
708	+	that an automatic refresh is no longer performed if an insert or update query contains
709	+	a returning clause that updates one or more fields on the current row. A full row
710	+	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
711	+	field values and the select query contains read only fields. Use of Insert/update
712	+	returning should be significantly more efficient than executing a refresh query.
713	+
714	+	This behaviour change is intended to be backwards compatible and there should be no need to change
715	+	existing programs, other than to improve performance by using the new capability.
716	+
717	+	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
718	+	they are called when the dataset row is being deleted, there is no value in
719	+	updating the current record from the query result. Instead, a new event handler
720	+	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
721	+	an OnDeleteReturning event handler is provided then it is called with the IResults returned
722	+	by the query. The event handler can then interrogate the query results and
723	+	perform whatever action is necessary. For example to confirm, to the user,
724	+	the deletion of a row with the returned values.
725	+
726	+	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
727	+	any Computed By or Identity Columns. The IBTables example has been updated to
728	+	illustrate the computation of the employee Full Name on update.
729	+
730	+	5. TIBTable: The GeneratorField property is now published.
731	+
732	+	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
733	+	When InsertSQL is generated, the Identity columns are not included in the list of values to
734	+	be inserted. A RETURNING clause is added to the insert statement to return the value of
735	+	each Identity column after the insert is executed.
736	+
737	+	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
738	+	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
739	+	Insert..Returning clause.
740	+
741	+	8. TIBGenerator: small performance improvement by not preparing query each time
742	+	a new value is generated.
743	+
744	+	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
745	+
746	+	10. Property editors will now sync table name to a System Table when "Include System
747	+	Tables" is selected and the query is for a System Table.
748	+
749	+	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
750	+	values are no longer converted to milliseconds from TDateTime and then back again
751	+	to TDateTime (the conversion to milliseconds is the default TDataset approach).
752	+
753	+	12. Property Editors handling of Stored Procedures.
754	+	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
755	+	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
756	+	query).
757	+	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
758	+
759	+	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
760	+	can be used to select a package. If non-empty, the stored procedure name is
761	+	expected to be a stored procedure defined in the specified package and the
762	+	generated SQL will be as required for a stored procedure located in a package.
763	+
764	+	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
765	+	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
766	+	which a stored procedure can be selected. With no package name selected, non-package
767	+	stored procedures are listed.
768	+
769	+	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
770	+	for password on reconnect.
771	+
772	+	16. TIBDatabase: use IAttachment for connection default character set id, code page
773	+	and character set name.
774	+
775	+	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
776	+	DB info lookups"
777	+
778	+	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
779	+
780	+	19. Add a property Editor for TIBUpdate.RefreshSQL.
781	+
782	+	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
783	+	parameters. This stops an exception being raised when the field cannot be
784	+	located in the record buffer.
785	+
786	+	21. Property Editors now automatically include System Tables when opened and when the query table
787	+	is a System Table.
788	+
789	+	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
790	+	This avoids errors due to a stale SQRB or SRB being used for the next query.
791	+
792	+	23. IBServices: Service attach parameters now include "expected_db". This is used to
793	+	add the SPB item isc_spb_expected_db. This names a database using
794	+	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
795	+	database. examples/services re-written to illustrate use of "expected_db".
796	+
797	+	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
798	+	This avoids truncated backups when the server returns a timeout (busy) response.
799	+
800	+	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
801	+
802	+	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
803	+	databasenames. These are respectively expanded to the local system's temp directory
804	+	(including trailing delimiter) or to a prescribed data directory (including
805	+	trailing delimiter). Under Unix systems the data directory is a hidden directory
806	+	in the user's home directory. The hidden directory name is either the string returned
807	+	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
808	+	Under Windows, the directory is the same as the Data Directory as decribed
809	+	above but instead prefixed by the User's application data path. These may be
810	+	used to improve application portability for Personal Databases.
811	+
812	+	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
813	+	this has not worked for a long time and is not useful either. FieldDefs should be
814	+	managed using the Fields Editor as with any other dataset. To access the fields
815	+	editor for a TIBTable component, double click on the component. The fields editor
816	+	is then displayed.
817	+
818	+	28. TIBDatabaseInfo: new properties/function
819	+	* DateDBCreated (returns date/time database created)
820	+	* TransactionCount (returns no. of active transactions)
821	+	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
822	+	* PagesFree (Firebird 3 or later)
823	+	* PagesUsed (Firebird 3 or later)
824	+	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
825	+	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
826	+
827	+	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
828	+
829	+	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
830	+
831	+	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
832	+	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
833	+
834	+	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
835	+	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
836	+	firing during backup and restore.
837	+
838	+	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
839	+	for verbose output using the new property "StatisticsRequested".
840	+	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
841	+
842	+	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
843	+
844	+	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
845	+	palette. This uses the online validation feature added in Firebird 2.5. The
846	+	services's properties enable inclusion/exclusion of tables and indexes using
847	+	regular expressions. See.
848	+	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
849	+
850	+	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
851	+	option on a database.
852	+
853	+	37. TIBCustomService: Assign method implemented to allow copying of service login
854	+	context between service API components. "Detach" method now only detaches
855	+	service when last reference to the service interface detaches. Tidy up of
856	+	code for SetActive and Attach methods including password hiding.
857	+
858	+	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
859	+	and used to determine the auth method and protocol used for the connection.
860	+
861	+	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
862	+	a Create Database Statement generated by IBX.
863	+
864	+	40. All IBServices now have an additional published property "PortNo". This may
865	+	be set to a non-standard port number when necessary. If zero then the default
866	+	port number is used.
867	+
868	+	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
869	+	and not just the mouse.
870	+
871	+	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
872	+
873	+	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
874	+	image index and selected image index for each node to be set from a database field.
875	+
876	+	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
877	+	then database schema includes grants to all users. If not present then the
878	+	only user grants included are those to User PUBLIC.
879	+
880	+	45. TIBTreeView: performance improvement. When expanding include both expanded node
881	+	and child nodes in dataset.
882	+
883	+
884	+	IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
885	+
886	+	1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
887	+	changes.
888	+
889	+	2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
890	+	Bug could result in truncated multi-byte character set values.
891	+
892	+	3. Changes consequential on moving fbintf character set utility functions from
893	+	IFirebirdAPI to IAttachment.
894	+
895	+	4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
896	+
897	+	5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
898	+	results in autocomplete ignoring prefix text.
899	+
900	+	6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
901	+	entering a new name into the text box.
902	+
903	+	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
904	+	Firebird rather than recomputing it.
905	+
906	+	8. Property Editor positioning tidy up: All IBX Property editors should now be
907	+	screen centre. Previously some were "poDesigned" which may be inappropriate
908	+	for multi monitor desktops.
909	+
910	+	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
911	+
912	+	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
913	+	a transaction and always reset the object.
914	+
915	+	12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
916	+
917	+	13. TIBXScript: Allow for override of database filename in Create Database statements.
918	+
919	+	14. IBLocaldb: Support initialisation of the database from an SQL script in addition
920	+	to a gbak format archive.
921	+
922	+	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
923	+
924	+	16. IBLocaldb: Drop database if error creating an empty database.
925	+
926	+	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
927	+	unless selected node not in current dataset.
928	+
929	+	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
930	+	to TIBCustomService, and IBlocalDB code tidy up.
931	+
932	+	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
933	+	behaviour due to uninitialised variable.
934	+
935	+	20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
936	+	integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
937	+
938	+	21. IBSQL: When Database changed ensure that all resources are freed.
939	+
940	+	22. IBCustomDataset: When database changed ensure that queries an unprepared.
941	+
942	+	23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
943	+	* Line Wrap on SQL Token boundaries (on user command)
944	+	* auto-complete table names in drop down list of table names
945	+	* Double click on tablename or field name adds to SQL text
946	+
947	+	24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
948	+
949	+	25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
950	+	TVariantArray. Seems to avoid memory corruption in Windows (probably a
951	+	workaround for a problem in fpc 3.0.4 win64).
952	+
953	+	26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
954	+
955	+	27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
956	+
957	+	IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
958	+
959	+	1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
960	+	include remote system name.
961	+
962	+	2. TIBExtract: No longer include comment header and COMMIT statement for empty
963	+	tables when data included in output.
964	+
965	+	3. Profiling: IBSQL now has conditional compilation flags to enable query performance
966	+	and timing information to be written to stdout. This may be used to locate
967	+	performance bottlenecks.
968	+
969	+	4. SQLParser: only call "OnChanging" event handler when value is different.
970	+
971	+	5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
972	+
973	+	6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
974	+	that BindFields is called when the query is next activated. Avoids FieldName
975	+	not found error.
976	+
977	+	7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
978	+	purpose and allows the programmer to define any action they want for Update, Insert
979	+	or Delete. This may be complex SQL (similar to a Trigger), application specific
980	+	filtering of updates, or use of statements such as Grant or Revoke instead of
981	+	normal DML. See User Manual for more information.
982	+
983	+	IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
984	+
985	+	1. TIBEvents: Fix uninitialised variable that could result in lost events.
986	+
987	+	2. TIBExtract: Added support for FB3 "USAGE" privilege.
988	+
989	+	3. TIBExtract: data formatted as Charset set "octets" is now output using
990	+	hexadecimal notation.
991	+
992	+	4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
993	+	using a simple XML format.
994	+
995	+	5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
996	+	grants to these objects.
997	+
998	+	6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
999	+	dependency problems restoring complex databases.
1000	+
1001	+	7. TIBXScript: This component has been restructured to allow for the processing of
1002	+	embedded XML in INSERT statements and to support interactive sources in addition
1003	+	to non-interactive data sources such as files.
1004	+
1005	+	8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1006	+
1007	+	9. TIBXScript: ISQL compatiable Set statements are now supported:
1008	+	SET SQL DIALECT
1009	+	SET TERM
1010	+	SET AUTODDL
1011	+	SET BAIL
1012	+	SET ECHO
1013	+	SET COUNT
1014	+	SET STATS
1015	+	SET NAMES <character set>
1016	+
1017	+	10. IBVersion unit added to hold current IBX Version Number information.
1018	+
1019	+	11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1020	+	and domain definitions.
1021	+
1022	+	12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1023	+	fully supported.
1024	+
1025	+	13. TIBExtract: when a database dump includes data, the generator values are now also set.
1026	+
1027	+	14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1028	+
1029	+	IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1030	+
1031	+	See also doc/IBX4LazarusGuide.pdf for important information on
1032	+	upgrading to IBX2.
1033	+
1034	+	1. Size property of TIBStringField is now the width in characters of the field
1035	+	and not the byte length. This applies only to multi-byte character sets such
1036	+	as UTF8. The original approach aligned with TStringField. However, the TStringField
1037	+	code is not recognised as a bug and hence this change to align the behaviour.
1038	+	The TStringField change is expected in fpc 3.2.0.
1039	+
1040	+	2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1041	+	true (default) then Size property value saved in the lfm is ignored. Size is
1042	+	always set from the dynamic information read from the database. It is unclear
1043	+	why anyone would want to override this and set Size to false.
1044	+
1045	+	3. ibxscript: should now handle correctly a Case..End statement within a procedure
1046	+	block.
1047	+
1048	+	4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1049	+	exist when an attempt is made to connect to it (run time only) then an attempt
1050	+	is made to create the database.
1051	+
1052	+	5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1053	+	has been successfully created as a result of a call to CreateDatabase or when
1054	+	creating a database after it was found not to exist.
1055	+
1056	+	6.  DBControlGrid: a race condition could result in the wrong row image being
1057	+	written to the cache. This has been avoided by a trip round the message
1058	+	loop before rendering the row image.
1059	+
1060	+	7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
1061	+	a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1062	+	known to risk corrupt rendering of row images when the control is first
1063	+	displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1064	+	of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1065	+
1066	+	8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1067	+	a TDateEdit control located on an editor panel.
1068	+
1069	+	9.  TIBExtract: brought up-to-date plus many bug fixes.
1070	+
1071	+	10. DBControlGrid: Removed memory leak when updating rows.
1072	+
1073	+	11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

1075	+	IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1076	+
1077	+	1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1078	+	when target codepage is CP_NONE. This is a workaround for
1079	+	http://bugs.freepascal.org/view.php?id=30622.
1080	+
1081	+	2. DBLog option removed from TIBStatisticalService - not supported by server
1082	+	since Firebird 1.5.
1083	+
1084	+	3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1085	+	similar.
1086	+
1087	+	4. IBCodePage: updated mapping between codepages and character id.
1088	+
1089	+	5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1090	+	Firebird. Character sets with a char width of two are not UTF16.
1091	+
1092	+	6. Strings received from the database are now always transliterated into UTF8
1093	+	regardless of the database character set or connection character set. This
1094	+	is for compatibility with the LCL.
1095	+
1096	+	IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1097	+
1098	+	1. IBBlob: Defer reading of blob until read method called. This avoids having to
1099	+	read in an entire blob just to get the size of the blob. General performance
1100	+	improvement when opening datasets containing blobs.
1101	+
1102	+	2. Clearing a  Blob now sets the corresponding field's modified flag.
1103	+
1104	+	3. IBLookupCombo: When not performing auto-complete, original query sort order
1105	+	is now used.
1106	+
1107	+	4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1108	+	determined.
1109	+
1110	+	5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1111	+
1112	+	6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1113	+	lazarus 1.6.0
1114	+
1115	+	7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1116	+	compilation error.
1117	+
1118	+	IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1119	+
1120	+	1. No character set specified for connection: when a text blob is retrieved, the
1121	+	character set is determined by looking up the native character set using then
1122	+	Firebird API. Otherwise a text mode blob is assumed to have the same character
1123	+	set as the connection.
1124	+
1125	+	2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1126	+	for Login Dialog returing a change to the database path.
1127	+
1128	+	3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1129	+	to be changed from that given in the TIBDatabase/TIBServer component and for the
1130	+	entered value to be saved on a project specific basis (design time only).
1131	+
1132	+	4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1133	+	column fieldname. If they are the same then it is acts as a look up for the KeyValue
1134	+	Otherwise, it sets the column text to the selected ListField Value.
1135	+
1136	+	5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1137	+	column width.
1138	+
1139	+	6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1140	+	and a case insensitive search is requested.
1141	+
1142	+	7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1143	+	or column ListSource.
1144	+
1145	+	8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1146	+	unprepare) when closing and the text has not changed.
1147	+
1148	+	9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1149	+	Less likely to cause a cursor re-use error on Windows.
1150	+
1151	+	10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1152	+	Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1153	+
1154	+	11. TIBTreeView: Guard against nil destination on record changed
1155	+
1156	+	12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1157	+	string type with the code page set to reflect the returned field encoding after
1158	+	Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1159	+	earlier versions.
1160	+
1161	+	13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1162	+	will now result in transliteration to the code page specified for the Firebird driver
1163	+	if the assigned string has a different code page. FPC 3.0.0 onwards only.
1164	+
1165	+	14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1166	+	is ignored and the lc_ctype value, when the database is opened, is set to align with
1167	+	the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1168	+	platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1169	+	3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1170	+	the GETACP is used to determine the Windows code page.
1171	+
1172	+	15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1173	+	name used as the lc_ctype when the database was opened. Only valid while the
1174	+	Database is connected.
1175	+
1176	+	16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1177	+	id that corresponds to the DefaultCharSetName.
1178	+
1179	+	IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1180	+
1181	+	1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1182	+	path is given and database attach fails due to access permission issues on the
1183	+	temp directory or security database, then the attach is retried with "localhost:"
1184	+	prefixing the databasename. This should avoid problems when the database has to
1185	+	be accessed by a local (e.g. classic) server and libfbembed is used.
1186	+
1187	+	2. Windows: revised search order for Firebird DLL:
1188	+	i.   The Firebird Embedded Server in the application Directory.
1189	+	ii.  If the FIREBIRD environment variable is set then the directory this
1190	+	points to is searched for the FB Client DLL and then then underlying
1191	+	"bin" directory.
1192	+	iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1193	+	is used to locate the Firebird installation directory and the underlying
1194	+	"bin" directory is searched for the FB Client DLL.
1195	+	iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1196	+	are searched for the FB Client DLL.
1197	+	v.   The PATH Environment variable is used to search for the FB Client DLL.
1198	+	vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1199	+
1200	+	3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1201	+	See doc/readme.scriptengine and example applications.
1202	+
1203	+	4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1204	+	simplify the use of the embedded firebird server on both Linux and Windows platforms.
1205	+	See dpc/readme.localdatabase and example applications.
1206	+
1207	+	5. IBDynamicGrid: Reordering on column header click should now also work for
1208	+	dynamic columns.
1209	+
1210	+	6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1211	+	between incrementing/decrementing the lock count and signalling the event.
1212	+
1213	+	IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1214	+
1215	+	1.3.2 was never formally released and only made available as beta copies.
1216	+
1217	+	1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1218	+
1219	+	2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1220	+
1221	+	3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1222	+
1223	+	4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1224	+	i.e. when it is a calculated field
1225	+
1226	+	5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1227	+	This problem was due to a race condition between recalculating row heights and
1228	+	determining which row was selected by the mouse click. The row height calculation
1229	+	is now deferred by an extra trip round the message loop allowing the row to
1230	+	be always calculated on the current grid layout rather than risking it being
1231	+	calculated on the grid layout after the expanded row has been shrunk.
1232	+
1233	+	6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1234	+	Windows.
1235	+
1236	+	7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1237	+	These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1238	+	to be determined at runtime. See doc/readme.charactersets.html.
1239	+
1240	+	8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1241	+	TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1242	+
1243	+	9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1244	+	TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1245	+	1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1246	+
1247	+	Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1248	+	from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1249	+	implies no truncation.
1250	+
1251	+	10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1252	+
1253	+	11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1254	+	(avoids "Not in Edit Mode" error).
1255	+
1256	+	12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1257	+
1258	+	13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1259	+	DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1260	+
1261	+	14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1262	+
1263	+	15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1264	+
1265	+	16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1266	+
1267	+	17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1268	+
1269	+	IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1270	+
1271	+	1.   OnCloseUp Event Handler added to TDBLookupProperties
1272	+
1273	+	2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1274	+	problem with row size when exception is called.
1275	+
1276	+	3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1277	+
1278	+	4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1279	+	in a TCustomComboBox and ignores return key if in a TCustomMemo
1280	+
1281	+	5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1282	+	keyed in i.e. when autocomplete not performed
1283	+
1284	+	6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1285	+	console mode applications with all LCL required functions (builtin dialogs and
1286	+	cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1287	+	not included in your project, IBX should compile and link with a console mode program.
1288	+	See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1289	+	console mode application or the IDE will automatically assume that your
1290	+	application is GUI based. Instead, you should include the ibexpressconsolemode package.
1291	+
1292	+	IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1293	+	to use the built in dialogs and cursor management. IBDialogs is
1294	+	included by default if "ibexpress" is in your project source's "uses" clause.
1295	+	This should be the case for all projects created through the IDE. This is why
1296	+	you do not want to add the ibexpress package to console mode applications. The
1297	+	ibexpressconsolemode package has been created to allow console mode programs
1298	+	to avoid adding LCL dependencies when using IBX, while still having the
1299	+	unit search paths set up correctly.
1300	+
1301	+	Existing users should check to ensure that the "ibexpress" unit is included in
1302	+	each project's source file (*.lpr).
1303	+
1304	+	You may find that in order for the IDE to recognise that ibexpressconsolemode
1305	+	exists, you have to first open the package in the IDE and then close it. This
1306	+	adds it to the most recently accessed packages list. To make it permanently
1307	+	available, add the package name to lazarus' staticpackages.inc file.
1308	+
1309	+	Thanks to Julio Jiménez for suggesting support of console mode.
1310	+
1311	+	7.   SQL Parser can now accept quoted strings that include new lines
1312	+
1313	+	8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1314	+	of text on start of edit. This is particularly useful when tabbing to a
1315	+	column and then inserting text.
1316	+
1317	+	9.   New Examples provided for IB Services and ISQLMonitor.
1318	+
1319	+	10. Fix error when writing to blob streams that recorded only the last buffer
1320	+	write in the blob stream. In most cases, this did not cause a problem as the
1321	+	IB Blob Stream is written in a single write. However, with the TDBImage, write
1322	+	of a graphic type prefix was lost which caused a problem when the image could
1323	+	not be automatically recognised.
1324	+
1325	+	11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1326	+	already open" errors due to random numbers used for the cursor name being identical.
1327	+
1328	+	12. IBTable: corrected error that could result in an "Index out of bounds" error
1329	+	when opening the table and the Primary Key is the last or only column in the
1330	+	table. Thanks to Rick Hoover for the fix.
1331	+
1332	+	13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1333	+	of "UTF-8", and update list of available database character sets. Existing
1334	+	users should check the current lc_ctype setting in their applications.
1335	+
1336	+	IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1337	+
1338	+	1.  Firebird Services: avoid List Index error when opening a service with an
1339	+	empty Params property.
1340	+
1341	+	2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1342	+	Link now set up in Loaded method - avoids occasional failure to apply
1343	+	SQL markup on initial open.
1344	+
1345	+	3.  "Employees" example performance improvements when scrolling.
1346	+
1347	+	4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1348	+	TFrame. Force recaching of selected frame to avoid GTK race (results in a
1349	+	random image cached).
1350	+
1351	+	5.  DBControlGrid: Should now react to changes in panel height at run time.
1352	+
1353	+	6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1354	+	even when further rows exist.
1355	+
1356	+	7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1357	+	always be derived from panel height and setting this property can cause confusion.
1358	+	Note for existing projects: to avoid a missing property error at run time,
1359	+	each form using the DBControlGrid must be opened, updated and saved in the IDE
1360	+	in order to remove the property value from the lfm.
1361	+
1362	+
1363	+	IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1364	+
1365	+	1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1366	+	call Prepare before setting parameter values.
1367	+
1368	+	2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1369	+
1370	+	3.  Code tidyup and more robust handling of dsql information result vector.
1371	+
1372	+	4.  Support for centralised handling of transaction status changes. TIBTransaction
1373	+	has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1374	+	and "AfterExecQuery". The first three are called after the same event is called
1375	+	for an IBCustomDataSet descendent using the Transaction. The fourth is called
1376	+	after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1377	+	enable monitoring of transaction status changes for a given transaction to be
1378	+	handled in a single place. For example, when a change to the dataset occurs
1379	+	an indicator can be set that shows the user that in order to save changes,
1380	+	the transaction should be committed.  Rather than doing this per dataset, this
1381	+	can now be done per transaction.
1382	+
1383	+	5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1384	+	the dataset is scrolled. However, any changes to the current row are, by default,
1385	+	discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1386	+	have a new property "DataSetCloseAction" that adds automatic posting of changes
1387	+	on dataset close. If this property is set to dcDiscardChanges (default) then the
1388	+	behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1389	+	then IBX will attempt to post any unsaved changes before the dataset is closed
1390	+	(and after the BeforeClose event handler is called). The exception is when the
1391	+	dataset is being closed as a result of a transaction rollback. In this case,
1392	+	no action is taken and any unsaved  changes are discarded. This avoids both
1393	+	unnecessary overhead and the risk that a validation error may occur in the Post
1394	+	raising an exception and thereby preventing a rollback.
1395	+
1396	+	6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1397	+	In earlier versions, the Display Width was set to the maximum byte width rather than the character
1398	+	width. Display Widths are now corrected by dividing by the max byte width per character.
1399	+	For UTF8 character sets, the byte width is four and hence the Display Width will be
1400	+	the byte width divided by 4. The byte width of each character set is determined
1401	+	dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1402	+	system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1403	+
1404	+	7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1405	+
1406	+	8.  IBLookupComboEditBox: List should now always be restored to full list when the
1407	+	control loses focus. Default Key press default interval reduced to 200ms.
1408	+
1409	+	9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1410	+	when dataset rows are less than visible rows.
1411	+
1412	+	10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1413	+	does not exist or DataSet is empty. More responsive on dataset open. New event
1414	+	OnRestorePosition. Column sort disabled if no header row.
1415	+
1416	+	11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1417	+	while dataset state is dsInsert. Avoids posting errors.
1418	+
1419	+	12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1420	+	avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1421	+
1422	+	13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1423	+
1424	+	14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1425	+	to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1426	+	a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1427	+	always "posts" the current record regardless or whether or not it may be more appropriate
1428	+	to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1429	+	"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1430	+	as the first action of the "Post" method and allows the handler to convert the Post
1431	+	into a Cancel if that is the appropriate action on moving to a different row. This is
1432	+	achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1433	+	raised here, but it may still be more appropriate to validate a post and signal
1434	+	a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1435	+
1436	+	15. On Unix derived systems, the Firebird library name can now be given as a colon
1437	+	separated list. Each library name on the list is tried in turn, in left to right
1438	+	order with the first found being used as the firebird library. By default, on Linux,
1439	+	the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1440	+	overidden by the FBLIB environment variable or the OnGetLibraryName function.
1441	+
1442	+	Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1443	+	then it will still attempt to access the database via the Firebird Server and will
1444	+	require a username and password. If only the pathname is given, then the username
1445	+	and password should be omitted and the unix file permissions are used to grant
1446	+	access.
1447	+
1448	+	IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1449	+
1450	+	1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1451	+	rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1452	+	that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1453	+	corresponds to a row of the linked DataSource. Any data aware control on the
1454	+	replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1455	+
1456	+	2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1457	+	When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1458	+	takes place during database access. This may be useful when there are performance issues with
1459	+	the change of cursor. Setting the property to false suppresses the change of cursor.
1460	+
1461	+	3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1462	+	and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1463	+	Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1464	+	making all changes permanent immediately rather than when the transaction is explicitly
1465	+	committed.
1466	+
1467	+	4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1468	+	using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1469	+
1470	+	IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1471	+
1472	+	Development version only.
1473	+
1474	+	IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1475	+
1476	+	1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1477	+	This is typically used during an "OnBeforeOpen" event handler to manipulate the
1478	+	"Where" and "Having" clauses to implement user specified filters of arbitrary
1479	+	complexity.
1480	+
1481	+	2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1482	+	three new data aware controls dependent on IBX and which make use of the SQL Parser.
1483	+	These are:
1484	+
1485	+	- TIBLookupComboEditBox
1486	+	- TIBDynamicGrid
1487	+	- TIBTreeview
1488	+
1489	+	TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1490	+	of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1491	+	to revise the available list and restrict it to items that are prefixed by the
1492	+	typed text (either case sensitive or case insensitive). Autoinsert allows a
1493	+	newly typed entry to be added to the list dataset and included in the available
1494	+	list items.
1495	+
1496	+	TIBDynamicGrid is a TDBGrid descendent that provides for:
1497	+	- automatic resizing of selected columns to fill the available row length
1498	+	- automatic positioning and sizing of a "totals" control, typically at the
1499	+	column footer, on a per column basis.
1500	+	- DataSet resorting on header row click, sorting the dataset by the selected column.
1501	+	A second click on the same header cell reversed the sort order.
1502	+	- Support for a "Panel Editor". That is on clicking the indicator column, the row
1503	+	is automatically expanded and a panel superimposed on it. The panel can have any
1504	+	number of child controls, typically data aware controls with the same datasource
1505	+	as the grid allowing for editing of additional fields and more complex editors.
1506	+	- Reselection of the same row following resorting.
1507	+	- A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1508	+	Its properties are specified on a per column basis and allows for one or more
1509	+	columns to have their values selected from a list provided by a dataset.
1510	+	Autocomplete and autoinsert are also available. The existing picklist editor
1511	+	is unaffected by the extension.
1512	+
1513	+	TIBTreeView is a data aware TCustomTreeView.
1514	+
1515	+	3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1516	+	zero scale will no longer return an error. An Int64 will be returned instead.
1517	+
1518	+	4. TIBTransaction now has events for Before and After Transaction End and a new function
1519	+	"GetEndAction" allowing the EndAction to be accessed by these event handlers.
1520	+
1521	+	5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1522	+	repeated multiple times.
1523	+
1524	+	6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1525	+	check used to get in the way of using Stored Procedures, and "Update or Insert"
1526	+	statements.
1527	+
1528	+	7. Insert, Modify and Delete property Editors now support Query Generation from
1529	+	Stored Procedures.
1530	+
1531	+	8. Three new examples illustrate the use of the new IB Controls
1532	+
1533	+
1534	+	IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1535	+
1536	+	1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1537	+	setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1538	+	Gabor Boros for reporting this problem and for testing the improvements).
1539	+
1540	+	2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1541	+	See readme.field+param.names in the doc folder.
1542	+
1543	+	3. IBX SQL Editors will now automatically add double quotes around column names when the database
1544	+	dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1545	+
1546	+	4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1547	+
1548	+	5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1549	+	actions.
1550	+
1551	+	6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1552	+	thanks to Yuriy Kopnin for pointing this out).
1553	+
1554	+	7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1555	+
1556	+	8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1557	+	for both fields and parameter setting.
1558	+
1559	+	9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1560	+	visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1561	+
1562	+	10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1563	+	when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1564	+
1565	+	11. TIBTable now has a property editor for "MasterFields"
1566	+
1567	+	12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1568	+	GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1569	+
1570	+	13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1571	+	of settings is unrecognised. Selecting this radio button has no effect on the settings.
1572	+

1575	+
1576	+	1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1577	+
1578	+	IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1579	+
1580	+	1. In a TIBCustomDataset descendent, a generator now only sets the value when
1581	+	it is null. This allows for alternative user defined setting of the generator
1582	+
1583	+	Many thanks to Julio Jiménez for this fix
1584	+
1585	+	2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1586	+	and suggests that the user may have forgotten to install it.
1587	+
1588	+	IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1589	+
1590	+	1. Conditional compilation used to limit registration of TIntegerField to
1591	+	Lazarus versions less than 1.1
1592	+
1593	+	2. When a database connection is created, character set is now by default set
1594	+	to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1595	+	1250 to 1254.
1596	+

1599	+
1600	+	1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1601	+
1602	+
1603	+	IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1604	+
1605	+	1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1606	+	Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1607	+
1608	+	2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1609	+	package is changed to do this (which it should do).
1610	+
1611	+	IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1612	+
1613	+	1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1614	+
1615	+	2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1616	+
1617	+	3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1618	+
1619	+	4. Property editors should now correctly resize.
1620	+
1621	+	5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1622	+	(restored original functionality)
1623	+
1624	+	6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1625	+	library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
