2
3	<	1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
4	<	not SQL Identifiers are now supported.
3	>	1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4	>	case sensitive
5
6	<	2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
7	<	passed to the Firebird engine for execution.
6	>	2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7
8	<	3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
9	<	is made to scroll back.
8	>	3. New API Calls:
9	>	IColumnMetaData.GetStatement
10	>	IColumnMetaData.GetTransaction
11	>	ISQLData.GetStrLength
12	>	IResults.GetStatement
13	>	IAttachment.OpenBlob (using Blob metadata)
14	>	IAttachment.OpenArray (using array metadata)
15
16	<	4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
16	>	4. FBMessages: removal of unused messages
17
18	<	5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
15	<	only enclosed in double quotes in SQL dialect 3 and when it needs to be.
18	>	5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19
20	<	6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
18	<	validated. If no match is found in the list of field names and the database has
19	<	been opened in SQL Dialect 3, then the ListField Name is converted to upper case
20	<	if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
20	>	6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21
22	<	7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
23	<	with fpc 3.2.

23
24	<	IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
24	>	1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25	>	where the second character of the parameter name is a numeric.
26
27	+	2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28	+	This returns the isc_version connection information as one or more lines.
29	+	This is the same information as returned by isql with the -z option.
30
31	<	1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
32	<	and is used to override the default settings in the client side "firebird.conf" This
33	<	includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
31	<	Each line of the string list should be a setting in the same format as "firebird.conf".
32	<	For example "WireCompression = true" in order to request wire compression on the client side.
31	>	3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32	>	is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33	>	compiler option then the Firebird 3 API is no longer compiled in.
34
35	<	Note: explicit settings in the client side "firebird.conf" appear to take precedence
35	<	over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
36	<	also require a compatible setting in the server side "firebird.conf". For example
37	<	"WireCompression = true" must also be set in the server's "firebird.conf" for wire
38	<	compression to be used.
35	>	4. IColumnMetaData: new method.
36
37	<	Whether or not WireCompression or WireCrypt are in use can be checked using the information
38	<	returned with the Client/Server protocol version. See ibx/examples/dbadmin and
39	<	ibx/examples/dbinfo for examples of how to display this information.
37	>	TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38	>	dfDateTime,   {SQL DATETIME}
39	>	dfTime);
40
41	<	2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
45	<	is a "convenience" property. If set the "WireCompression=true" is added to the
46	<	ConfigOverrides. If unchecked then this setting is removed.
41	>	function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42
43	<	3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
44	<	not "INT64".
43	>	This returns the max. number of characters returned by the "AsString" method
44	>	when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45
46	<	4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
47	<	These are:
53	<	property TimestampFormat: string;
54	<	property DateFormat: string;
55	<	property TimeFormat: string;
46	>	5. Additional argument for IAttachment.PrepareWithNamedParameters -
47	>	CaseSensitiveParams: boolean = false
48
49	<	Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
50	<	DATETIME and TIME. The format strings use the standard FPC date/time format
51	<	characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
49	>	If this argument is set to true then SQL parameter names are assumed to be case
50	>	sensitive and must be referenced (using ISQLParams.ByName) using the case
51	>	sensitive name.
52
53	<	If any of the above properties are set to an empty string, then the locale default
54	<	is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
55	<	locale default is extended by appending '.zzz' to include milliseconds.
53	>	6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54	>	is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55	>	.AsCurrency) and then subsequently to update the value to a non-numeric string
56	>	using .AsString.
57
65	–	TIBCSVDataOut by default sets these properties to the empty string, while the other
66	–	two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
58
68	–	5. New published property for TIBCSVDataOut:
69	–	property QuoteStrings: boolean (default true)
59
60	<	If false then strings are unquoted, otherwise, the QuoteChar property value is
72	<	used to delimit each and every string in the output.
60	>	FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61
62	<	6. New published properties for TIBCSVDataOut:
75	<	property FieldSeparator: string;
76	<	property HeaderSeparator: string;
62	>	1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63
64	<	Respectively, these provide the separator character(s) used to separate fields
65	<	in data and header rows. Both default to ','.
64	>	2. Restrict IsMultiThread check to Unix only for compatibility with
65	>	https://bugs.freepascal.org/view.php?id=30535
66
67	<	7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
68	<	TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
69	<	property OnFormatTextString;
67	>	3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68	>	named parameters and is intended to avoid problems with (e.g.) Execute Block
69	>	and processing internal parameters as statement parameters.
70
71	<	This event handler can be used to process text strings before they are included
72	<	in the output e.g. to replace unprintable characters with alternative strings.
87	<	This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
71	>	4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72	>	or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73
74	<	8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
90	<	Uses "FindParam" if in order to find out if a parameter with a given name exists
91	<	and without raising and exception if it does not.
74	>	5. New function added to IB.pas
75
76	<	9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
94	<	consistency with SQL queries.
76	>	function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77
78	<	10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
79	<	When true, SQL statement parameter names are parsed case sensitive. Note for
80	<	TIBDataSet only applies to Select query.
78	>	This allows a Firebird Library to be loaded from an explicit path. use the
79	>	IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80	>	the library. It is possible to load Firebird libraries from different locations
81	>	simultaneously, each with a distinct IFirebirdAPI.
82
83	<	11. IBEvents: removing a TIBEvent component from a form should no longer result in
101	<	an IDE exception.
83	>	FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84
85	<	12. LocalDBSupport: initial database creation should now work correctly
86	<	when the schema source is an sql file.
85	>	1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86	>	program compiled with -CR command line switch.
87
88	<	13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
89	<	when defined, this handler will be called by the internal TIBXScript during
90	<	initial database creation when the schema source is an sql file and may be used
109	<	to provide a visual indication of progress in console mode.
88	>	2. IServiceManager additions (informational):
89	>	function getProtocol: TProtocol;
90	>	function getPortNo: AnsiString;
91
92	<	14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
93	<	to true while a new local database is being created and its schema populated.
94	<	Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
95	<	when the database is disconnected/connected during the create DB procedure.
92	>	3. IServiceManager improved error handling. Interfaces changed:
93	>	function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94	>	function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95	>	function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96
97	<	15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
98	<	are now always ignored and replaced by the user name and password provided as
118	<	the login parameters for the TIBDatabase referenced from the TIBXScript. The
119	<	IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
120	<	completely ignored if this property is true.
97	>	4. IAttachment addition (informational)
98	>	function GetSecurityDatabase: AnsiString;
99
100	<	16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
101	<	to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
102	<	ImageIndex and SelectImageIndex values on AddNode.
100	>	5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101	>	thus now returns accumulated stats for a select statement from opening a cursor
102	>	up to the last fetch.
103
104	<	17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
105	<	read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
128	<	the same database connection.
104	>	6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105	>	the problem.
106
107	<	18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
108	<	if provided, this should be an conditional SQL expression suitable for
132	<	including in an SQL Select statement "where" clause. If non-empty and the
133	<	"Filtered" property is true then the SQL expression provided as the value of
134	<	the "Filter" property is "ANDed" with any existing condition statement
135	<	in the SQL statement's "Where" clause.
107	>	7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108	>	replaces deprecated "comp" type.
109
110	<	If the "Filter" property is set at run time, the "Filtered" property is true
138	<	and the dataset is already open, then the dataset is closed and re-opened automatically.
110	>	10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111
112	<	The "Filter" condition may include IBX style parameters. In which case, their
141	<	value must be set by the dataset's "OnBeforeOpen" event handler.
112	>	11. URL Connection Strings: inet4 and inet6 now recognised.
113
114	<	This is a public property for TIBDataSet and TIBQuery query and intended for
144	<	use at run time.
114	>	12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115
116	<	Note: The property is a published property of TIBTable. The TIBTable functionality
147	<	is unaffected by this change.
116	>	13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117
149	–	IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
118
119	<	1. Remove need to check for IsMultiThread by providing access to GUI timers via
152	<	IBGUIInterface. Note: master/detail delay timer does not apply to console
153	<	mode apps.
119	>	FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120
121	<	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
156	<	statement. This avoids problems if "Execute Block" is used as the Query.
121	>	1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122
123	<	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
124	<	internal SQL tokeniser routines.
123	>	2. IAttachment: add two new methods
124	>	function HasDefaultCharSet: boolean;
125	>	function GetDefaultCharSetID: integer;
126
127	<	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
128	<	as a select statement, with or without CTEs.
127	>	These return, respectively, true if a connection default character set was
128	>	specified and the character set id of the connection default character set.
129	>	The DefaultCharSetID is cached when the connection is opened and hence does not
130	>	require a database lookup.
131
132	<	5. IBSQLParser: parser now recognises the "ROWS" clause.
132	>	3. Avoid exception when a text blob is a stored procedure parameter.
133
134	<	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
167	<	internal SQL tokeniser routines.
134	>	4. Update test suite to include a test for a stored proc returning a text blob.
135
136	<	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
137	<	being raised for valid set statements processed by a data formatter.
136	>	5. IAttachment: add
137	>	function GetRemoteProtocol: AnsiString;
138	>	function GetODSMajorVersion: integer;
139	>	function GetODSMinorVersion: integer;
140	>	function GetAuthenticationMethod: AnsiString;
141
142	<	8. New published property for TIBDatabase and TIBXServicesConnection. This is
143	<	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
174	<	the path of the Firebird Library used by the database/services connection.
142	>	These results are cached when the connection is opened and hence do not
143	>	require a database lookup.
144
145	<	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
146	<	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
178	<	services connection.
145	>	6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146	>	connect string used to create/connect to the database.
147
148	<	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
149	<	or param name is not a valid SQL identifier.
148	>	7. IAttachment: Create Database using SQL statement. The username and password
149	>	are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150	>	It is now possible to use IAttachment disconnect/connect to reconnect to
151	>	a database for which the initial connection was established by a create
152	>	database sql statement. Available in FPC only.
153
154	<	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
184	<	view of whether the text box should be editable when no DataSource is specified.
185	<	TIBLookupComboEditBox has been updated to workaround this problem. As long as
186	<	ReadOnly is false, the text box is editable when no DataSource is specified.
154	>	8. Update Test 1 to test 5, 6 and 7 above.
155
156	<	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
189	<	the FBLIB environment variable. If you do not want to permit this then you
190	<	must modify the Register procedure in the design/IBDBReg.pas unit to remove
191	<	this setting.
156	>	9. IBUtils code tidy up.
157
158	<	IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
158	>	10. Parameter Block interfaces "find" method. As documented, this should have
159	>	returned a nil interface when the item could not be found. Instead, an empty
160	>	interface item was returned. "Find" now works as documented and will return
161	>	a nil interface if the item cannot be found.
162
163	<	1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
196	<	Utf8EscapeControlChars
163	>	11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164
165	<	IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
165	>	12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166	>	requests with additional parameters. This is to enable support for fb_info_page_contents
167	>	(return of page contents). Response to fb_info_page_contents returned as
168	>	a string with code page CP_NONE.
169
170	<	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
171	<	all previous copies of the IBX source code tree before installing this release.
170	>	13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171	>	test suite updated.
172
173	<	The IBX packages used by most users have not changed, with one exception. The
174	<	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
205	<	to use the IBServices unit in your applications, please add the iblegacyServices
206	<	to the list of dependencies. To do this, open the Project Inspector and select
207	<	Add->New Requirement and select "ibLegacyServices" from the list of available
208	<	packages.
173	>	14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174	>	a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175
176	<	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
177	<	the IBServices unit providing what is intended to be a clearer and easier to
178	<	use set of IB Services components. See Chapter 10 of the IBX User Guide for
213	<	more information and the guide to "Firebird Service Management Using IBX".
214	<	As indicated above, the legacy services components are still available and
215	<	provided in a separate package. There is no need to update working applications
216	<	using the older versions except for an additional package dependency.
176	>	15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177	>	An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178	>	default connection port to be specified.
179
180	<	2. The IBX packages and source code tree have been re-organised in an attempt to
219	<	finally get rid of the "duplicate ppu" warnings. This re-organisation should
220	<	not affect existing users. Section 2.3 of the IBX User Guide describes the
221	<	new set of IBX packages.
180	>	FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181
182	<	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
183	<	updated to use the new Services API components.
182	>	1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183	>	Scale is no longer ignored.
184
185	<	4. The iblocal package has been updated to use the new Services API components.
185	>	2. Fix issues with setting SQL Param values using SetAsString with Date values
186	>	not in locale format but which are recognised by Firebird. Date values that
187	>	cannot be converted to a string using Pascal library are now passed through
188	>	to Firebird as Text Strings.
189
190	<	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
191	<	TIBXSecurityService. It had been wrongly classified in the previous version
230	<	as a per database configuration item. It is global to a server and hence
231	<	correctly positioned as part of the Security Package. In the DBAdmin example,
232	<	the setting has moved to the mappings page.
190	>	3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191	>	UTF8 and not UNICODE_FSS.
192
193	<	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
194	<	are ignored.
193	>	4. Charset ID problem. When using Firebird 3, with no default database character set
194	>	and a column has a non-default collation specified, an incorrect character set
195	>	id was being reported that could result in a 'division by zero' error when
196	>	used by IBX. This has now been fixed.
197
198	<	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
199	<	closed before the database is dropped. Before and After Disconnect event handlers
200	<	are also fired.
198	>	5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199	>	CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200	>	the character sets supported can be updated on a per database basis. That is
201	>	it is possible to add a (Firebird) user defined character set to a database.
202
203	<	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
204	<	is started and not just the first time.
203	>	6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204	>	set supported by Firebird with the API.
205
206	<	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
207	<	depenendency with comp type.
206	>	7. Add missing isc_info_db_read_only to list of decoded Database Information items
207	>	in FBOutputBlock.pas and update test suite to include this item.
208
209	<	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
209	>	8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210
211	<	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
212	<	then this is recognised and not ignored.
211	>	9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212	>	library or finding it by disk location, the PATH environment variable is now also set to
213	>	include the FIREBIRD directory. This is to ensure that the correct dlls in the
214	>	firebird client library dependencies are loaded.
215
216	<	12. TIBDataSet, TIBQuery, TIBTable: additions:
253	<	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
254	<	function GetPerfStatistics(var stats: TPerfCounters): boolean;
255	<	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
216	>	10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217
218	<	GetRowsAffected returns the affected row counts from the last insert/update/delete
258	<	if EnableStatistics = true then GetPerfStatistics returns the current stats
259	<	counters for the select query. Note: stats accumulate after each fetch from
260	<	the database. To get total query cost after open, call the "Last" method
261	<	and then GetPerfStatistics.
218	>	11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219
220	<	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
220	>	12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221
222	<	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
223	<	in parenthesises.
222	>	13. FB30Statement: A check has been added to ensure that all SQL Parameters
223	>	have been given a value (including NULL). Previously, failing to set the
224	>	value of an SQL Parameter could give rise to unpredictable results or
225	>	an SQLDA error.
226
227	<	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
269	<	SQL identifiers are always delimited by double quotes. If false, then they are
270	<	only delimited if the identifier is a reserved word, contains lower case or special
271	<	characters. Set this property to true to retain previous behaviour.
227	>	14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228
229	<	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
230	<	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
229	>	15. FBAttachment: Avoid string reference count error when processing an Ansistring
230	>	parameter in an array of const passed to IAttachment.OpenCursor, etc.
231
232	<	16. TIBDataSet, TIBQuery, TIBTable: addition:
233	<	property MasterDetailDelay: integer {defaults to zero}
232	>	16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233	>	of const passed to IAttachment.OpenCursor, etc.
234
279	–	When non-zero and the dataset is a detail table referencing a master table
280	–	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
281	–	then a synchronisation delay is added (in milliseconds) between the master
282	–	row changing and the detail dataset being re-opened. If the master dataset
283	–	is scrolled before the delay expires then the delay is reset. This can be used
284	–	to avoid performance overheads when scrolling through a large master dataset.
235
236	<	Note: uses fptimer and hence requires a thread manager. Under Linux the
287	<	chreads unit must be included in your project. TTimer is not used in order
288	<	to avoid an LCL dependency. Requires FPC 3.0.2 or later.

238	<	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
291	<	with Extract Option eoDatabase.
238	>	1. Change syntax to Mode Delphi
239
240	<	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
241	<	When a deLayoutChanged event is reported on the ListSource dataset, the
295	<	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
296	<	relationship with the control's datasource (master).
240	>	2. Change all uses of string type to explicit AnsiString in order to ensure
241	>	compatibility between Delphi and FPC.
242
243	<	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
243	>	3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244	>	defined for each interface.
245
246	<	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
301	<	stubs. Pedantic fix really, as procedures output in dependency order anyway.
246	>	4. Generics syntax variations for Delphi added
247
248	<	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
249	<	DDL (Firebird 3 and later only).
248	>	5. PChar replaced with PByte expect where an actual string is being referenced,

250
251	<	22. TIBLookupComboBox Autocomplete Fixes:
307	<	i. Only appended text is now selected after autocomplete.
308	<	ii. Uppercase keys no longer ignored for autocomplete.
309	<	iii. Retain Prefix case is now honoured correctly.
310	<	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
311	<	before autocomplete performed. i.e. behaviour now the same as when
312	<	no DataSource assigned.
251	>	6. Review of type definitions in IBExternals to ensure Delphi compatibility
252
253	<	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
315	<	between SQL statements.
253	>	7. Testsuite updated for Delphi
254
255	<	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
318	<	ObjectNames are converted to upper case before matching against metadata object
319	<	names, unless the objectname is delimited by double quotes, in which case, the
320	<	double quotes are removed and the remaining string is used (unmodified) to match

256
257	<	If true then the ObjectName is used as is without modification and matched
258	<	against the metadata object name. No attempt is made to remove double quotes.
257	>	1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258	>	large blobs and the FB3 API.
259
260	<	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
261	<	with eoTrigger, these extract types can be used to select only Database Triggers,
328	<	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.

261	>	event block.
262
263	<	26. TIBXScript: If an exception occurs during the processing of a statement, the
331	<	statement separate character is now reset to the default (';').
263	>	3. Avoid invalid XSQLDA error when the only parameter is updated to null
264
265	<	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
265	>	4. Array Handling: fix problem with text arrays with character set none. When the

269
270	<	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
336	<	a commit or reconnect statement and instead activated only when next SQL statement
337	<	is executed.
270	>	5. IBUtils: List of reserved words brought up-to-date

294
295	<	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
365	<	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
366	<	information). However, this is also a very useful mechanism for returning updated computed by
367	<	column values. Values returned as a result of executing an Insert or Update statement
368	<	replace existing values in the current row for each corresponding column.
295	>	1. Initial Release
296
370	–	Previously, if a dataset's select query included read only (computed by) fields then
371	–	an automatic row refresh was performed after an insert or update query had been processed,
372	–	irrespective of the setting of the "ForcedUpdates" property. This has changed such
373	–	that an automatic refresh is no longer performed if an insert or update query contains
374	–	a returning clause that updates one or more fields on the current row. A full row
375	–	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
376	–	field values and the select query contains read only fields. Use of Insert/update
377	–	returning should be significantly more efficient than executing a refresh query.
378	–
379	–	This behaviour change is intended to be backwards compatible and there should be no need to change
380	–	existing programs, other than to improve performance by using the new capability.
381	–
382	–	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
383	–	they are called when the dataset row is being deleted, there is no value in
384	–	updating the current record from the query result. Instead, a new event handler
385	–	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
386	–	an OnDeleteReturning event handler is provided then it is called with the IResults returned
387	–	by the query. The event handler can then interrogate the query results and
388	–	perform whatever action is necessary. For example to confirm, to the user,
389	–	the deletion of a row with the returned values.
390	–
391	–	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
392	–	any Computed By or Identity Columns. The IBTables example has been updated to
393	–	illustrate the computation of the employee Full Name on update.
394	–
395	–	5. TIBTable: The GeneratorField property is now published.
396	–
397	–	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
398	–	When InsertSQL is generated, the Identity columns are not included in the list of values to
399	–	be inserted. A RETURNING clause is added to the insert statement to return the value of
400	–	each Identity column after the insert is executed.
401	–
402	–	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
403	–	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
404	–	Insert..Returning clause.
405	–
406	–	8. TIBGenerator: small performance improvement by not preparing query each time
407	–	a new value is generated.
408	–
409	–	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
410	–
411	–	10. Property editors will now sync table name to a System Table when "Include System
412	–	Tables" is selected and the query is for a System Table.
413	–
414	–	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
415	–	values are no longer converted to milliseconds from TDateTime and then back again
416	–	to TDateTime (the conversion to milliseconds is the default TDataset approach).
417	–
418	–	12. Property Editors handling of Stored Procedures.
419	–	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
420	–	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
421	–	query).
422	–	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
423	–
424	–	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
425	–	can be used to select a package. If non-empty, the stored procedure name is
426	–	expected to be a stored procedure defined in the specified package and the
427	–	generated SQL will be as required for a stored procedure located in a package.
428	–
429	–	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
430	–	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
431	–	which a stored procedure can be selected. With no package name selected, non-package
432	–	stored procedures are listed.
433	–
434	–	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
435	–	for password on reconnect.
436	–
437	–	16. TIBDatabase: use IAttachment for connection default character set id, code page
438	–	and character set name.
439	–
440	–	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
441	–	DB info lookups"
442	–
443	–	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
444	–
445	–	19. Add a property Editor for TIBUpdate.RefreshSQL.
446	–
447	–	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
448	–	parameters. This stops an exception being raised when the field cannot be
449	–	located in the record buffer.
450	–
451	–	21. Property Editors now automatically include System Tables when opened and when the query table
452	–	is a System Table.
453	–
454	–	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
455	–	This avoids errors due to a stale SQRB or SRB being used for the next query.
456	–
457	–	23. IBServices: Service attach parameters now include "expected_db". This is used to
458	–	add the SPB item isc_spb_expected_db. This names a database using
459	–	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
460	–	database. examples/services re-written to illustrate use of "expected_db".
461	–
462	–	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
463	–	This avoids truncated backups when the server returns a timeout (busy) response.
464	–
465	–	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
466	–
467	–	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
468	–	databasenames. These are respectively expanded to the local system's temp directory
469	–	(including trailing delimiter) or to a prescribed data directory (including
470	–	trailing delimiter). Under Unix systems the data directory is a hidden directory
471	–	in the user's home directory. The hidden directory name is either the string returned
472	–	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
473	–	Under Windows, the directory is the same as the Data Directory as decribed
474	–	above but instead prefixed by the User's application data path. These may be
475	–	used to improve application portability for Personal Databases.
476	–
477	–	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
478	–	this has not worked for a long time and is not useful either. FieldDefs should be
479	–	managed using the Fields Editor as with any other dataset. To access the fields
480	–	editor for a TIBTable component, double click on the component. The fields editor
481	–	is then displayed.
482	–
483	–	28. TIBDatabaseInfo: new properties/function
484	–	* DateDBCreated (returns date/time database created)
485	–	* TransactionCount (returns no. of active transactions)
486	–	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
487	–	* PagesFree (Firebird 3 or later)
488	–	* PagesUsed (Firebird 3 or later)
489	–	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
490	–	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
491	–
492	–	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
493	–
494	–	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
495	–
496	–	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
497	–	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
498	–
499	–	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
500	–	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
501	–	firing during backup and restore.
502	–
503	–	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
504	–	for verbose output using the new property "StatisticsRequested".
505	–	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
506	–
507	–	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
508	–
509	–	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
510	–	palette. This uses the online validation feature added in Firebird 2.5. The
511	–	services's properties enable inclusion/exclusion of tables and indexes using
512	–	regular expressions. See.
513	–	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
514	–
515	–	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
516	–	option on a database.
517	–
518	–	37. TIBCustomService: Assign method implemented to allow copying of service login
519	–	context between service API components. "Detach" method now only detaches
520	–	service when last reference to the service interface detaches. Tidy up of
521	–	code for SetActive and Attach methods including password hiding.
522	–
523	–	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
524	–	and used to determine the auth method and protocol used for the connection.
525	–
526	–	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
527	–	a Create Database Statement generated by IBX.
528	–
529	–	40. All IBServices now have an additional published property "PortNo". This may
530	–	be set to a non-standard port number when necessary. If zero then the default
531	–	port number is used.
532	–
533	–	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
534	–	and not just the mouse.
535	–
536	–	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
537	–

562	–	5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
563	–	results in autocomplete ignoring prefix text.
564	–
565	–	6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
566	–	entering a new name into the text box.
567	–
568	–	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
569	–	Firebird rather than recomputing it.
570	–
571	–	8. Property Editor positioning tidy up: All IBX Property editors should now be
572	–	screen centre. Previously some were "poDesigned" which may be inappropriate
573	–	for multi monitor desktops.
574	–
575	–	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
576	–
577	–	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
578	–	a transaction and always reset the object.

586	–
587	–	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
588	–
589	–	16. IBLocaldb: Drop database if error creating an empty database.
590	–
591	–	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
592	–	unless selected node not in current dataset.
593	–
594	–	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
595	–	to TIBCustomService, and IBlocalDB code tidy up.
596	–
597	–	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
598	–	behaviour due to uninitialised variable.
599	–
600	–	20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
601	–	integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
602	–
603	–	21. IBSQL: When Database changed ensure that all resources are freed.
604	–
605	–	22. IBCustomDataset: When database changed ensure that queries an unprepared.
606	–
607	–	23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
608	–	* Line Wrap on SQL Token boundaries (on user command)
609	–	* auto-complete table names in drop down list of table names
610	–	* Double click on tablename or field name adds to SQL text
611	–
612	–	24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
613	–
614	–	25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
615	–	TVariantArray. Seems to avoid memory corruption in Windows (probably a
616	–	workaround for a problem in fpc 3.0.4 win64).
617	–
618	–	26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
619	–
620	–	27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

624	–	1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
625	–	include remote system name.
626	–
627	–	2. TIBExtract: No longer include comment header and COMMIT statement for empty
628	–	tables when data included in output.
629	–
630	–	3. Profiling: IBSQL now has conditional compilation flags to enable query performance
631	–	and timing information to be written to stdout. This may be used to locate
632	–	performance bottlenecks.
633	–
634	–	4. SQLParser: only call "OnChanging" event handler when value is different.
635	–
636	–	5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
637	–
638	–	6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
639	–	that BindFields is called when the query is next activated. Avoids FieldName
640	–	not found error.
641	–
642	–	7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
643	–	purpose and allows the programmer to define any action they want for Update, Insert
644	–	or Delete. This may be complex SQL (similar to a Trigger), application specific
645	–	filtering of updates, or use of statements such as Grant or Revoke instead of
646	–	normal DML. See User Manual for more information.

661	–	grants to these objects.
662	–
663	–	6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
664	–	dependency problems restoring complex databases.
665	–
666	–	7. TIBXScript: This component has been restructured to allow for the processing of
667	–	embedded XML in INSERT statements and to support interactive sources in addition
668	–	to non-interactive data sources such as files.
669	–
670	–	8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.

696	–	See also doc/IBX4LazarusGuide.pdf for important information on
697	–	upgrading to IBX2.
698	–
699	–	1. Size property of TIBStringField is now the width in characters of the field
700	–	and not the byte length. This applies only to multi-byte character sets such
701	–	as UTF8. The original approach aligned with TStringField. However, the TStringField
702	–	code is not recognised as a bug and hence this change to align the behaviour.
703	–	The TStringField change is expected in fpc 3.2.0.
704	–
705	–	2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
706	–	true (default) then Size property value saved in the lfm is ignored. Size is
707	–	always set from the dynamic information read from the database. It is unclear
708	–	why anyone would want to override this and set Size to false.
709	–
710	–	3. ibxscript: should now handle correctly a Case..End statement within a procedure
711	–	block.
712	–
713	–	4. IBDatabase: new property - CreateIfNotExists. If true and database does not
714	–	exist when an attempt is made to connect to it (run time only) then an attempt
715	–	is made to create the database.
716	–
717	–	5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
718	–	has been successfully created as a result of a call to CreateDatabase or when
719	–	creating a database after it was found not to exist.
720	–
721	–	6.  DBControlGrid: a race condition could result in the wrong row image being
722	–	written to the cache. This has been avoided by a trip round the message
723	–	loop before rendering the row image.
724	–
725	–	7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
726	–	a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
727	–	known to risk corrupt rendering of row images when the control is first
728	–	displayed. If necessary use "Application.QueueAsyncCall" to delay opening
729	–	of the dataset (see DBControlGrid examples) until the Form's Window has been created.
730	–
731	–	8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
732	–	a TDateEdit control located on an editor panel.
733	–

749	–	3. ibxscript: An error is no longer generated for "on commit preserve rows" or
750	–	similar.
751	–
752	–	4. IBCodePage: updated mapping between codepages and character id.
753	–
754	–	5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
755	–	Firebird. Character sets with a char width of two are not UTF16.
756	–
757	–	6. Strings received from the database are now always transliterated into UTF8
758	–	regardless of the database character set or connection character set. This

763	–	1. IBBlob: Defer reading of blob until read method called. This avoids having to
764	–	read in an entire blob just to get the size of the blob. General performance
765	–	improvement when opening datasets containing blobs.
766	–
767	–	2. Clearing a  Blob now sets the corresponding field's modified flag.
768	–

784	–
785	–	1. No character set specified for connection: when a text blob is retrieved, the
786	–	character set is determined by looking up the native character set using then
787	–	Firebird API. Otherwise a text mode blob is assumed to have the same character
788	–	set as the connection.
789	–
790	–	2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
791	–	for Login Dialog returing a change to the database path.
792	–
793	–	3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
794	–	to be changed from that given in the TIBDatabase/TIBServer component and for the
795	–	entered value to be saved on a project specific basis (design time only).
796	–
797	–	4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
798	–	column fieldname. If they are the same then it is acts as a look up for the KeyValue
799	–	Otherwise, it sets the column text to the selected ListField Value.
800	–
801	–	5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
802	–	column width.
803	–
804	–	6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
805	–	and a case insensitive search is requested.
806	–
807	–	7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
808	–	or column ListSource.
809	–
810	–	8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
811	–	unprepare) when closing and the text has not changed.
812	–
813	–	9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
814	–	Less likely to cause a cursor re-use error on Windows.
815	–
816	–	10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
817	–	Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
818	–
819	–	11. TIBTreeView: Guard against nil destination on record changed
820	–
821	–	12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
822	–	string type with the code page set to reflect the returned field encoding after
823	–	Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
824	–	earlier versions.
825	–
826	–	13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
827	–	will now result in transliteration to the code page specified for the Firebird driver
828	–	if the assigned string has a different code page. FPC 3.0.0 onwards only.
829	–
830	–	14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
831	–	is ignored and the lc_ctype value, when the database is opened, is set to align with
832	–	the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
833	–	platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
834	–	3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
835	–	the GETACP is used to determine the Windows code page.
836	–
837	–	15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
838	–	name used as the lc_ctype when the database was opened. Only valid while the
839	–	Database is connected.
840	–
841	–	16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage

845	–
846	–	1. Unix: If Firebird Embedded Server shared object is loaded and a local database
847	–	path is given and database attach fails due to access permission issues on the
848	–	temp directory or security database, then the attach is retried with "localhost:"
849	–	prefixing the databasename. This should avoid problems when the database has to
850	–	be accessed by a local (e.g. classic) server and libfbembed is used.
851	–
852	–	2. Windows: revised search order for Firebird DLL:
853	–	i.   The Firebird Embedded Server in the application Directory.
854	–	ii.  If the FIREBIRD environment variable is set then the directory this
855	–	points to is searched for the FB Client DLL and then then underlying
856	–	"bin" directory.
857	–	iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
858	–	is used to locate the Firebird installation directory and the underlying
859	–	"bin" directory is searched for the FB Client DLL.
860	–	iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
861	–	are searched for the FB Client DLL.
862	–	v.   The PATH Environment variable is used to search for the FB Client DLL.
863	–	vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.

883	–
884	–	2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
885	–
886	–	3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
887	–
888	–	4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
889	–	i.e. when it is a calculated field
890	–
891	–	5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
892	–	This problem was due to a race condition between recalculating row heights and
893	–	determining which row was selected by the mouse click. The row height calculation
894	–	is now deferred by an extra trip round the message loop allowing the row to
895	–	be always calculated on the current grid layout rather than risking it being
896	–	calculated on the grid layout after the expanded row has been shrunk.
897	–
898	–	6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
899	–	Windows.
900	–
901	–	7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
902	–	These properties allow the (Firebird) character set name for the field and the max number of bytes per character
903	–	to be determined at runtime. See doc/readme.charactersets.html.
904	–
905	–	8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
906	–	TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
907	–
908	–	9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
909	–	TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
910	–	1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
911	–
912	–	Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
913	–	from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
914	–	implies no truncation.
915	–
916	–	10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
917	–
918	–	11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
919	–	(avoids "Not in Edit Mode" error).
920	–
921	–	12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
922	–
923	–	13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
924	–	DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
925	–
926	–	14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.

940	–
941	–	3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
942	–
943	–	4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
944	–	in a TCustomComboBox and ignores return key if in a TCustomMemo
945	–
946	–	5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
947	–	keyed in i.e. when autocomplete not performed
948	–
949	–	6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
950	–	console mode applications with all LCL required functions (builtin dialogs and
951	–	cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
952	–	not included in your project, IBX should compile and link with a console mode program.
953	–	See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
954	–	console mode application or the IDE will automatically assume that your
955	–	application is GUI based. Instead, you should include the ibexpressconsolemode package.
956	–
957	–	IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
958	–	to use the built in dialogs and cursor management. IBDialogs is
959	–	included by default if "ibexpress" is in your project source's "uses" clause.
960	–	This should be the case for all projects created through the IDE. This is why
961	–	you do not want to add the ibexpress package to console mode applications. The
962	–	ibexpressconsolemode package has been created to allow console mode programs
963	–	to avoid adding LCL dependencies when using IBX, while still having the
964	–	unit search paths set up correctly.
965	–
966	–	Existing users should check to ensure that the "ibexpress" unit is included in
967	–	each project's source file (*.lpr).
968	–
969	–	You may find that in order for the IDE to recognise that ibexpressconsolemode
970	–	exists, you have to first open the package in the IDE and then close it. This
971	–	adds it to the most recently accessed packages list. To make it permanently
972	–	available, add the package name to lazarus' staticpackages.inc file.
973	–
974	–	Thanks to Julio Jiménez for suggesting support of console mode.
975	–
976	–	7.   SQL Parser can now accept quoted strings that include new lines
977	–
978	–	8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
979	–	of text on start of edit. This is particularly useful when tabbing to a
980	–	column and then inserting text.
981	–
982	–	9.   New Examples provided for IB Services and ISQLMonitor.
983	–
984	–	10. Fix error when writing to blob streams that recorded only the last buffer
985	–	write in the blob stream. In most cases, this did not cause a problem as the
986	–	IB Blob Stream is written in a single write. However, with the TDBImage, write
987	–	of a graphic type prefix was lost which caused a problem when the image could
988	–	not be automatically recognised.
989	–
990	–	11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
991	–	already open" errors due to random numbers used for the cursor name being identical.
992	–
993	–	12. IBTable: corrected error that could result in an "Index out of bounds" error
994	–	when opening the table and the Primary Key is the last or only column in the
995	–	table. Thanks to Rick Hoover for the fix.
996	–
997	–	13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
998	–	of "UTF-8", and update list of available database character sets. Existing
999	–	users should check the current lc_ctype setting in their applications.

1002	–
1003	–	1.  Firebird Services: avoid List Index error when opening a service with an
1004	–	empty Params property.
1005	–
1006	–	2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1007	–	Link now set up in Loaded method - avoids occasional failure to apply
1008	–	SQL markup on initial open.
1009	–
1010	–	3.  "Employees" example performance improvements when scrolling.
1011	–
1012	–	4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1013	–	TFrame. Force recaching of selected frame to avoid GTK race (results in a
1014	–	random image cached).
1015	–
1016	–	5.  DBControlGrid: Should now react to changes in panel height at run time.
1017	–
1018	–	6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1019	–	even when further rows exist.
1020	–
1021	–	7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1022	–	always be derived from panel height and setting this property can cause confusion.
1023	–	Note for existing projects: to avoid a missing property error at run time,
1024	–	each form using the DBControlGrid must be opened, updated and saved in the IDE
1025	–	in order to remove the property value from the lfm.

1029	–
1030	–	1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1031	–	call Prepare before setting parameter values.
1032	–
1033	–	2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1034	–
1035	–	3.  Code tidyup and more robust handling of dsql information result vector.
1036	–
1037	–	4.  Support for centralised handling of transaction status changes. TIBTransaction
1038	–	has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1039	–	and "AfterExecQuery". The first three are called after the same event is called
1040	–	for an IBCustomDataSet descendent using the Transaction. The fourth is called
1041	–	after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1042	–	enable monitoring of transaction status changes for a given transaction to be
1043	–	handled in a single place. For example, when a change to the dataset occurs
1044	–	an indicator can be set that shows the user that in order to save changes,
1045	–	the transaction should be committed.  Rather than doing this per dataset, this
1046	–	can now be done per transaction.
1047	–
1048	–	5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1049	–	the dataset is scrolled. However, any changes to the current row are, by default,
1050	–	discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1051	–	have a new property "DataSetCloseAction" that adds automatic posting of changes
1052	–	on dataset close. If this property is set to dcDiscardChanges (default) then the
1053	–	behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1054	–	then IBX will attempt to post any unsaved changes before the dataset is closed
1055	–	(and after the BeforeClose event handler is called). The exception is when the
1056	–	dataset is being closed as a result of a transaction rollback. In this case,
1057	–	no action is taken and any unsaved  changes are discarded. This avoids both
1058	–	unnecessary overhead and the risk that a validation error may occur in the Post
1059	–	raising an exception and thereby preventing a rollback.
1060	–
1061	–	6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1062	–	In earlier versions, the Display Width was set to the maximum byte width rather than the character
1063	–	width. Display Widths are now corrected by dividing by the max byte width per character.
1064	–	For UTF8 character sets, the byte width is four and hence the Display Width will be
1065	–	the byte width divided by 4. The byte width of each character set is determined
1066	–	dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1067	–	system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1068	–
1069	–	7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1070	–
1071	–	8.  IBLookupComboEditBox: List should now always be restored to full list when the
1072	–	control loses focus. Default Key press default interval reduced to 200ms.
1073	–
1074	–	9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1075	–	when dataset rows are less than visible rows.
1076	–
1077	–	10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1078	–	does not exist or DataSet is empty. More responsive on dataset open. New event
1079	–	OnRestorePosition. Column sort disabled if no header row.
1080	–
1081	–	11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1082	–	while dataset state is dsInsert. Avoids posting errors.
1083	–
1084	–	12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1085	–	avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1086	–
1087	–	13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1088	–
1089	–	14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1090	–	to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1091	–	a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1092	–	always "posts" the current record regardless or whether or not it may be more appropriate
1093	–	to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1094	–	"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1095	–	as the first action of the "Post" method and allows the handler to convert the Post
1096	–	into a Cancel if that is the appropriate action on moving to a different row. This is
1097	–	achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1098	–	raised here, but it may still be more appropriate to validate a post and signal
1099	–	a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1100	–
1101	–	15. On Unix derived systems, the Firebird library name can now be given as a colon
1102	–	separated list. Each library name on the list is tried in turn, in left to right
1103	–	order with the first found being used as the firebird library. By default, on Linux,
1104	–	the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1105	–	overidden by the FBLIB environment variable or the OnGetLibraryName function.
1106	–
1107	–	Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1108	–	then it will still attempt to access the database via the Firebird Server and will
1109	–	require a username and password. If only the pathname is given, then the username
1110	–	and password should be omitted and the unix file permissions are used to grant
1111	–	access.

1113	–	IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1114	–
1115	–	1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1116	–	rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1117	–	that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1118	–	corresponds to a row of the linked DataSource. Any data aware control on the
1119	–	replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1120	–
1121	–	2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1122	–	When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1123	–	takes place during database access. This may be useful when there are performance issues with
1124	–	the change of cursor. Setting the property to false suppresses the change of cursor.
1125	–
1126	–	3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1127	–	and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1128	–	Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1129	–	making all changes permanent immediately rather than when the transaction is explicitly
1130	–	committed.
1131	–
1132	–	4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1133	–	using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1140	–
1141	–	1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1142	–	This is typically used during an "OnBeforeOpen" event handler to manipulate the
1143	–	"Where" and "Having" clauses to implement user specified filters of arbitrary
1144	–	complexity.
1145	–
1146	–	2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1147	–	three new data aware controls dependent on IBX and which make use of the SQL Parser.
1148	–	These are:
1149	–
1150	–	- TIBLookupComboEditBox
1151	–	- TIBDynamicGrid
1152	–	- TIBTreeview
1153	–
1154	–	TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1155	–	of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1156	–	to revise the available list and restrict it to items that are prefixed by the
1157	–	typed text (either case sensitive or case insensitive). Autoinsert allows a
1158	–	newly typed entry to be added to the list dataset and included in the available
1159	–	list items.
1160	–
1161	–	TIBDynamicGrid is a TDBGrid descendent that provides for:
1162	–	- automatic resizing of selected columns to fill the available row length
1163	–	- automatic positioning and sizing of a "totals" control, typically at the
1164	–	column footer, on a per column basis.
1165	–	- DataSet resorting on header row click, sorting the dataset by the selected column.
1166	–	A second click on the same header cell reversed the sort order.
1167	–	- Support for a "Panel Editor". That is on clicking the indicator column, the row
1168	–	is automatically expanded and a panel superimposed on it. The panel can have any
1169	–	number of child controls, typically data aware controls with the same datasource
1170	–	as the grid allowing for editing of additional fields and more complex editors.
1171	–	- Reselection of the same row following resorting.
1172	–	- A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1173	–	Its properties are specified on a per column basis and allows for one or more
1174	–	columns to have their values selected from a list provided by a dataset.
1175	–	Autocomplete and autoinsert are also available. The existing picklist editor
1176	–	is unaffected by the extension.
1177	–
1178	–	TIBTreeView is a data aware TCustomTreeView.
1179	–
1180	–	3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1181	–	zero scale will no longer return an error. An Int64 will be returned instead.
1182	–
1183	–	4. TIBTransaction now has events for Before and After Transaction End and a new function
1184	–	"GetEndAction" allowing the EndAction to be accessed by these event handlers.
1185	–
1186	–	5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1187	–	repeated multiple times.
1188	–
1189	–	6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1190	–	check used to get in the way of using Stored Procedures, and "Update or Insert"
1191	–	statements.
1192	–
1193	–	7. Insert, Modify and Delete property Editors now support Query Generation from
1194	–	Stored Procedures.
1195	–
1196	–	8. Three new examples illustrate the use of the new IB Controls

1200	–
1201	–	1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1202	–	setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1203	–	Gabor Boros for reporting this problem and for testing the improvements).
1204	–
1205	–	2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1206	–	See readme.field+param.names in the doc folder.
1207	–
1208	–	3. IBX SQL Editors will now automatically add double quotes around column names when the database
1209	–	dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1210	–
1211	–	4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1212	–
1213	–	5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1214	–	actions.
1215	–
1216	–	6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1217	–	thanks to Yuriy Kopnin for pointing this out).
1218	–
1219	–	7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1220	–
1221	–	8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1222	–	for both fields and parameter setting.
1223	–
1224	–	9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1225	–	visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1226	–
1227	–	10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1228	–	when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1229	–
1230	–	11. TIBTable now has a property editor for "MasterFields"
1231	–
1232	–	12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1233	–	GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1234	–
1235	–	13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1236	–	of settings is unrecognised. Selecting this radio button has no effect on the settings.
