2
3	<	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4	<	all previous copies of the IBX source code tree before installing this release.
3	>	1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4	>	with a Firebrid 3 client library.
5
6	<	The IBX packages used by most users have not changed, with one exception. The
7	<	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8	<	to use the IBServices unit in your applications, please add the iblegacyServices
9	<	to the list of dependencies. To do this, open the Project Inspector and select
10	<	Add->New Requirement and select "ibLegacyServices" from the list of available
11	<	packages.
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.
11
12	<	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14	<	the IBServices unit providing what is intended to be a clearer and easier to
15	<	use set of IB Services components. See Chapter 10 of the IBX User Guide for
16	<	more information and the guide to "Firebird Service Management Using IBX".
17	<	As indicated above, the legacy services components are still available and
18	<	provided in a separate package. There is no need to update working applications
19	<	using the older versions except for an additional package dependency.
12	>	3.  IUtil.FormatStatus now used to format error messages when using new API
13
14	<	2. The IBX packages and source code tree have been re-organised in an attempt to
22	<	finally get rid of the "duplicate ppu" warnings. This re-organisation should
23	<	not affect existing users. Section 2.3 of the IBX User Guide describes the
24	<	new set of IBX packages.
14	>	4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15
16	<	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
17	<	updated to use the new Services API components.
16	>	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.
22
23	<	4. The iblocal package has been updated to use the new Services API components.
23	>	6.  New IFirebirdAPI Calls:
24	>	function GetClientMajor: integer;
25	>	function GetClientMinor: integer;
26
31	–	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32	–	TIBXSecurityService. It had been wrongly classified in the previous version
33	–	as a per database configuration item. It is global to a server and hence
34	–	correctly positioned as part of the Security Package. In the DBAdmin example,
35	–	the setting has moved to the mappings page.
27
28	<	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38	<	are ignored.
28	>	FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29
30	<	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
31	<	closed before the database is dropped. Before and After Disconnect event handlers
42	<	are also fired.
30	>	1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31	>	case sensitive
32
33	<	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45	<	is started and not just the first time.
33	>	2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34
35	<	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
36	<	depenendency with comp type.
35	>	3. New API Calls:
36	>	IColumnMetaData.GetStatement
37	>	IColumnMetaData.GetTransaction
38	>	ISQLData.GetStrLength
39	>	IResults.GetStatement
40	>	IAttachment.OpenBlob (using Blob metadata)
41	>	IAttachment.OpenArray (using array metadata)
42
43	<	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
43	>	4. FBMessages: removal of unused messages
44
45	<	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53	<	then this is recognised and not ignored.
45	>	5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46
47	<	12. TIBDataSet, TIBQuery, TIBTable: additions:
56	<	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57	<	function GetPerfStatistics(var stats: TPerfCounters): boolean;
58	<	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
47	>	6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48
49	<	GetRowsAffected returns the affected row counts from the last insert/update/delete
61	<	if EnableStatistics = true then GetPerfStatistics returns the current stats
62	<	counters for the select query. Note: stats accumulate after each fetch from
63	<	the database. To get total query cost after open, call the "Last" method
64	<	and then GetPerfStatistics.
49	>	FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50
51	<	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
51	>	1. Fix a problem with the SQL parameter parser that failed to recognise parameters
52	>	where the second character of the parameter name is a numeric.
53
54	<	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
55	<	in parenthesises.
54	>	2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55	>	This returns the isc_version connection information as one or more lines.
56	>	This is the same information as returned by isql with the -z option.
57
58	<	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
59	<	SQL identifiers are always delimited by double quotes. If false, then they are
60	<	only delimited if the identifier is a reserved word, contains lower case or special
74	<	characters. Set this property to true to retain previous behaviour.
58	>	3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59	>	is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60	>	compiler option then the Firebird 3 API is no longer compiled in.
61
62	<	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77	<	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
62	>	4. IColumnMetaData: new method.
63
64	<	16. TIBDataSet, TIBQuery, TIBTable: addition:
65	<	property MasterDetailDelay: integer {defaults to zero}
64	>	TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65	>	dfDateTime,   {SQL DATETIME}
66	>	dfTime);
67
68	<	When non-zero and the dataset is a detail table referencing a master table
83	<	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84	<	then a synchronisation delay is added (in milliseconds) between the master
85	<	row changing and the detail dataset being re-opened. If the master dataset
86	<	is scrolled before the delay expires then the delay is reset. This can be used
87	<	to avoid performance overheads when scrolling through a large master dataset.
68	>	function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69
70	<	Note: uses fptimer and hence requires a thread manager. Under Linux the
71	<	chreads unit must be included in your project. TTimer is not used in order
91	<	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
70	>	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.
72
73	<	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
74	<	with Extract Option eoDatabase.
73	>	5. Additional argument for IAttachment.PrepareWithNamedParameters -
74	>	CaseSensitiveParams: boolean = false
75
76	<	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
77	<	When a deLayoutChanged event is reported on the ListSource dataset, the
78	<	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99	<	relationship with the control's datasource (master).
76	>	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.
79
80	<	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
80	>	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
103	–	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104	–	stubs. Pedantic fix really, as procedures output in dependency order anyway.
85
106	–	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107	–	DDL (Firebird 3 and later only).
86
87	<	22. TIBLookupComboBox Autocomplete Fixes:
110	<	i. Only appended text is now selected after autocomplete.
111	<	ii. Uppercase keys no longer ignored for autocomplete.
112	<	iii. Retain Prefix case is now honoured correctly.
113	<	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114	<	before autocomplete performed. i.e. behaviour now the same as when
115	<	no DataSource assigned.
87	>	FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88
89	<	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118	<	between SQL statements.
89	>	1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90
91	<	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
92	<	ObjectNames are converted to upper case before matching against metadata object
122	<	names, unless the objectname is delimited by double quotes, in which case, the
123	<	double quotes are removed and the remaining string is used (unmodified) to match
124	<	against the metadata object name.
91	>	2. Restrict IsMultiThread check to Unix only for compatibility with
92	>	https://bugs.freepascal.org/view.php?id=30535
93
94	<	If true then the ObjectName is used as is without modification and matched
95	<	against the metadata object name. No attempt is made to remove double quotes.
94	>	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.
97
98	<	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
99	<	with eoTrigger, these extract types can be used to select only Database Triggers,
131	<	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
98	>	4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99	>	or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100
101	<	IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
101	>	5. New function added to IB.pas
102
103	<	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
136	<	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
137	<	RELEASE.
103	>	function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104
105	<	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
105	>	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.
109
110	<	1. IBExtract: Identity columns - add additional check for null column for generator name.
110	>	FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111
112	<	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
113	<	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
145	<	information). However, this is also a very useful mechanism for returning updated computed by
146	<	column values. Values returned as a result of executing an Insert or Update statement
147	<	replace existing values in the current row for each corresponding column.
112	>	1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113	>	program compiled with -CR command line switch.
114
115	<	Previously, if a dataset's select query included read only (computed by) fields then
116	<	an automatic row refresh was performed after an insert or update query had been processed,
117	<	irrespective of the setting of the "ForcedUpdates" property. This has changed such
152	<	that an automatic refresh is no longer performed if an insert or update query contains
153	<	a returning clause that updates one or more fields on the current row. A full row
154	<	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
155	<	field values and the select query contains read only fields. Use of Insert/update
156	<	returning should be significantly more efficient than executing a refresh query.
115	>	2. IServiceManager additions (informational):
116	>	function getProtocol: TProtocol;
117	>	function getPortNo: AnsiString;
118
119	<	This behaviour change is intended to be backwards compatible and there should be no need to change
120	<	existing programs, other than to improve performance by using the new capability.
119	>	3. IServiceManager improved error handling. Interfaces changed:
120	>	function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121	>	function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122	>	function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123
124	<	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
125	<	they are called when the dataset row is being deleted, there is no value in
163	<	updating the current record from the query result. Instead, a new event handler
164	<	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
165	<	an OnDeleteReturning event handler is provided then it is called with the IResults returned
166	<	by the query. The event handler can then interrogate the query results and
167	<	perform whatever action is necessary. For example to confirm, to the user,
168	<	the deletion of a row with the returned values.
124	>	4. IAttachment addition (informational)
125	>	function GetSecurityDatabase: AnsiString;
126
127	<	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
128	<	any Computed By or Identity Columns. The IBTables example has been updated to
129	<	illustrate the computation of the employee Full Name on update.
127	>	5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128	>	thus now returns accumulated stats for a select statement from opening a cursor
129	>	up to the last fetch.
130
131	<	5. TIBTable: The GeneratorField property is now published.
131	>	6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132	>	the problem.
133
134	<	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
135	<	When InsertSQL is generated, the Identity columns are not included in the list of values to
178	<	be inserted. A RETURNING clause is added to the insert statement to return the value of
179	<	each Identity column after the insert is executed.
134	>	7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135	>	replaces deprecated "comp" type.
136
137	<	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
182	<	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
183	<	Insert..Returning clause.
137	>	10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138
139	<	8. TIBGenerator: small performance improvement by not preparing query each time
186	<	a new value is generated.
139	>	11. URL Connection Strings: inet4 and inet6 now recognised.
140
141	<	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
141	>	12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142
143	<	10. Property editors will now sync table name to a System Table when "Include System
191	<	Tables" is selected and the query is for a System Table.
143	>	13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144
193	–	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
194	–	values are no longer converted to milliseconds from TDateTime and then back again
195	–	to TDateTime (the conversion to milliseconds is the default TDataset approach).
145
146	<	12. Property Editors handling of Stored Procedures.
198	<	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
199	<	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
200	<	query).
201	<	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
146	>	FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147
148	<	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
204	<	can be used to select a package. If non-empty, the stored procedure name is
205	<	expected to be a stored procedure defined in the specified package and the
206	<	generated SQL will be as required for a stored procedure located in a package.
148	>	1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149
150	<	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
151	<	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
152	<	which a stored procedure can be selected. With no package name selected, non-package
211	<	stored procedures are listed.
150	>	2. IAttachment: add two new methods
151	>	function HasDefaultCharSet: boolean;
152	>	function GetDefaultCharSetID: integer;
153
154	<	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
155	<	for password on reconnect.
154	>	These return, respectively, true if a connection default character set was
155	>	specified and the character set id of the connection default character set.
156	>	The DefaultCharSetID is cached when the connection is opened and hence does not
157	>	require a database lookup.
158
159	<	16. TIBDatabase: use IAttachment for connection default character set id, code page
217	<	and character set name.
159	>	3. Avoid exception when a text blob is a stored procedure parameter.
160
161	<	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
220	<	DB info lookups"
161	>	4. Update test suite to include a test for a stored proc returning a text blob.
162
163	<	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
163	>	5. IAttachment: add
164	>	function GetRemoteProtocol: AnsiString;
165	>	function GetODSMajorVersion: integer;
166	>	function GetODSMinorVersion: integer;
167	>	function GetAuthenticationMethod: AnsiString;
168
169	<	19. Add a property Editor for TIBUpdate.RefreshSQL.
169	>	These results are cached when the connection is opened and hence do not
170	>	require a database lookup.
171
172	<	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
173	<	parameters. This stops an exception being raised when the field cannot be
228	<	located in the record buffer.
172	>	6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173	>	connect string used to create/connect to the database.
174
175	<	21. Property Editors now automatically include System Tables when opened and when the query table
176	<	is a System Table.
175	>	7. IAttachment: Create Database using SQL statement. The username and password
176	>	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.
180
181	<	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
234	<	This avoids errors due to a stale SQRB or SRB being used for the next query.
181	>	8. Update Test 1 to test 5, 6 and 7 above.
182
183	<	23. IBServices: Service attach parameters now include "expected_db". This is used to
237	<	add the SPB item isc_spb_expected_db. This names a database using
238	<	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
239	<	database. examples/services re-written to illustrate use of "expected_db".
183	>	9. IBUtils code tidy up.
184
185	<	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
186	<	This avoids truncated backups when the server returns a timeout (busy) response.
185	>	10. Parameter Block interfaces "find" method. As documented, this should have
186	>	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.
189
190	<	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
190	>	11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191
192	<	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
193	<	databasenames. These are respectively expanded to the local system's temp directory
194	<	(including trailing delimiter) or to a prescribed data directory (including
195	<	trailing delimiter). Under Unix systems the data directory is a hidden directory
250	<	in the user's home directory. The hidden directory name is either the string returned
251	<	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
252	<	Under Windows, the directory is the same as the Data Directory as decribed
253	<	above but instead prefixed by the User's application data path. These may be
254	<	used to improve application portability for Personal Databases.

209	<	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
210	<	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
209	>	1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210	>	Scale is no longer ignored.
211
212	<	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
213	<	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
214	<	firing during backup and restore.
212	>	2. Fix issues with setting SQL Param values using SetAsString with Date values
213	>	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.
216
217	<	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
218	<	for verbose output using the new property "StatisticsRequested".

218	>	UTF8 and not UNICODE_FSS.
219
220	<	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
220	>	4. Charset ID problem. When using Firebird 3, with no default database character set
221	>	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.
224
225	<	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"

225	>	5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
226	>	CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
227	>	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.
229
230	<	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
231	<	option on a database.
230	>	6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231	>	set supported by Firebird with the API.
232
233	<	37. TIBCustomService: Assign method implemented to allow copying of service login
234	<	context between service API components. "Detach" method now only detaches
299	<	service when last reference to the service interface detaches. Tidy up of
300	<	code for SetActive and Attach methods including password hiding.
233	>	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.
235
236	<	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
303	<	and used to determine the auth method and protocol used for the connection.
236	>	8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237
238	<	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
239	<	a Create Database Statement generated by IBX.
238	>	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.
242
243	<	40. All IBServices now have an additional published property "PortNo". This may
309	<	be set to a non-standard port number when necessary. If zero then the default
310	<	port number is used.
243	>	10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244
245	<	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
313	<	and not just the mouse.
245	>	11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246
247	<	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
247	>	12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248
249	<	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
250	<	image index and selected image index for each node to be set from a database field.
249	>	13. FB30Statement: A check has been added to ensure that all SQL Parameters
250	>	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.
253
254	<	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
321	<	then database schema includes grants to all users. If not present then the

277
278	<	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by

278	>	6. Review of type definitions in IBExternals to ensure Delphi compatibility
279
280	<	8. Property Editor positioning tidy up: All IBX Property editors should now be

420	–
421	–	7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
422	–	purpose and allows the programmer to define any action they want for Update, Insert
423	–	or Delete. This may be complex SQL (similar to a Trigger), application specific

475	–	See also doc/IBX4LazarusGuide.pdf for important information on
476	–	upgrading to IBX2.
477	–
478	–	1. Size property of TIBStringField is now the width in characters of the field
479	–	and not the byte length. This applies only to multi-byte character sets such
480	–	as UTF8. The original approach aligned with TStringField. However, the TStringField
481	–	code is not recognised as a bug and hence this change to align the behaviour.
482	–	The TStringField change is expected in fpc 3.2.0.
483	–
484	–	2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
485	–	true (default) then Size property value saved in the lfm is ignored. Size is
486	–	always set from the dynamic information read from the database. It is unclear
487	–	why anyone would want to override this and set Size to false.
488	–
489	–	3. ibxscript: should now handle correctly a Case..End statement within a procedure
490	–	block.
491	–
492	–	4. IBDatabase: new property - CreateIfNotExists. If true and database does not
493	–	exist when an attempt is made to connect to it (run time only) then an attempt
494	–	is made to create the database.
495	–
496	–	5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
497	–	has been successfully created as a result of a call to CreateDatabase or when
498	–	creating a database after it was found not to exist.
499	–
500	–	6.  DBControlGrid: a race condition could result in the wrong row image being
501	–	written to the cache. This has been avoided by a trip round the message
502	–	loop before rendering the row image.
503	–
504	–	7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
505	–	a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
506	–	known to risk corrupt rendering of row images when the control is first
507	–	displayed. If necessary use "Application.QueueAsyncCall" to delay opening
508	–	of the dataset (see DBControlGrid examples) until the Form's Window has been created.
509	–
510	–	8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with

569	–	2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
570	–	for Login Dialog returing a change to the database path.
571	–
572	–	3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
573	–	to be changed from that given in the TIBDatabase/TIBServer component and for the
574	–	entered value to be saved on a project specific basis (design time only).
575	–
576	–	4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
577	–	column fieldname. If they are the same then it is acts as a look up for the KeyValue
578	–	Otherwise, it sets the column text to the selected ListField Value.
579	–
580	–	5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
581	–	column width.
582	–
583	–	6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
584	–	and a case insensitive search is requested.
585	–
586	–	7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
587	–	or column ListSource.
588	–
589	–	8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
590	–	unprepare) when closing and the text has not changed.
591	–
592	–	9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
593	–	Less likely to cause a cursor re-use error on Windows.
594	–
595	–	10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
596	–	Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
597	–
598	–	11. TIBTreeView: Guard against nil destination on record changed
599	–
600	–	12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
601	–	string type with the code page set to reflect the returned field encoding after
602	–	Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
603	–	earlier versions.
604	–
605	–	13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
606	–	will now result in transliteration to the code page specified for the Firebird driver
607	–	if the assigned string has a different code page. FPC 3.0.0 onwards only.
608	–
609	–	14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
610	–	is ignored and the lc_ctype value, when the database is opened, is set to align with
611	–	the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
612	–	platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
613	–	3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
614	–	the GETACP is used to determine the Windows code page.
615	–
616	–	15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
617	–	name used as the lc_ctype when the database was opened. Only valid while the
618	–	Database is connected.
619	–
620	–	16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
621	–	id that corresponds to the DefaultCharSetName.

624	–
625	–	1. Unix: If Firebird Embedded Server shared object is loaded and a local database
626	–	path is given and database attach fails due to access permission issues on the
627	–	temp directory or security database, then the attach is retried with "localhost:"
628	–	prefixing the databasename. This should avoid problems when the database has to
629	–	be accessed by a local (e.g. classic) server and libfbembed is used.
630	–
631	–	2. Windows: revised search order for Firebird DLL:
632	–	i.   The Firebird Embedded Server in the application Directory.
633	–	ii.  If the FIREBIRD environment variable is set then the directory this
634	–	points to is searched for the FB Client DLL and then then underlying
635	–	"bin" directory.
636	–	iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
637	–	is used to locate the Firebird installation directory and the underlying
638	–	"bin" directory is searched for the FB Client DLL.
639	–	iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
640	–	are searched for the FB Client DLL.
641	–	v.   The PATH Environment variable is used to search for the FB Client DLL.
642	–	vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
643	–
644	–	3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
645	–	See doc/readme.scriptengine and example applications.
646	–
647	–	4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
648	–	simplify the use of the embedded firebird server on both Linux and Windows platforms.
649	–	See dpc/readme.localdatabase and example applications.
650	–
651	–	5. IBDynamicGrid: Reordering on column header click should now also work for
652	–	dynamic columns.
653	–
654	–	6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
655	–	between incrementing/decrementing the lock count and signalling the event.

658	–
659	–	1.3.2 was never formally released and only made available as beta copies.
660	–
661	–	1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
662	–
663	–	2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
664	–
665	–	3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
666	–
667	–	4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
668	–	i.e. when it is a calculated field
669	–
670	–	5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
671	–	This problem was due to a race condition between recalculating row heights and
672	–	determining which row was selected by the mouse click. The row height calculation
673	–	is now deferred by an extra trip round the message loop allowing the row to
674	–	be always calculated on the current grid layout rather than risking it being
675	–	calculated on the grid layout after the expanded row has been shrunk.
676	–
677	–	6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
678	–	Windows.
679	–
680	–	7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
681	–	These properties allow the (Firebird) character set name for the field and the max number of bytes per character
682	–	to be determined at runtime. See doc/readme.charactersets.html.
683	–
684	–	8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
685	–	TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
686	–
687	–	9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
688	–	TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
689	–	1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
690	–
691	–	Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
692	–	from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
693	–	implies no truncation.
694	–
695	–	10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
696	–
697	–	11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
698	–	(avoids "Not in Edit Mode" error).
699	–
700	–	12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
701	–
702	–	13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
703	–	DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
704	–
705	–	14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
706	–
707	–	15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
708	–
709	–	16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
710	–
711	–	17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

714	–
715	–	1.   OnCloseUp Event Handler added to TDBLookupProperties
716	–
717	–	2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
718	–	problem with row size when exception is called.
719	–
720	–	3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
721	–
722	–	4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
723	–	in a TCustomComboBox and ignores return key if in a TCustomMemo
724	–
725	–	5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
726	–	keyed in i.e. when autocomplete not performed
727	–
728	–	6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
729	–	console mode applications with all LCL required functions (builtin dialogs and
730	–	cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
731	–	not included in your project, IBX should compile and link with a console mode program.
732	–	See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
733	–	console mode application or the IDE will automatically assume that your
734	–	application is GUI based. Instead, you should include the ibexpressconsolemode package.
735	–
736	–	IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
737	–	to use the built in dialogs and cursor management. IBDialogs is
738	–	included by default if "ibexpress" is in your project source's "uses" clause.
739	–	This should be the case for all projects created through the IDE. This is why
740	–	you do not want to add the ibexpress package to console mode applications. The
741	–	ibexpressconsolemode package has been created to allow console mode programs
742	–	to avoid adding LCL dependencies when using IBX, while still having the
743	–	unit search paths set up correctly.
744	–
745	–	Existing users should check to ensure that the "ibexpress" unit is included in
746	–	each project's source file (*.lpr).
747	–
748	–	You may find that in order for the IDE to recognise that ibexpressconsolemode
749	–	exists, you have to first open the package in the IDE and then close it. This
750	–	adds it to the most recently accessed packages list. To make it permanently
751	–	available, add the package name to lazarus' staticpackages.inc file.
752	–
753	–	Thanks to Julio Jiménez for suggesting support of console mode.
754	–
755	–	7.   SQL Parser can now accept quoted strings that include new lines
756	–
757	–	8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
758	–	of text on start of edit. This is particularly useful when tabbing to a
759	–	column and then inserting text.
760	–
761	–	9.   New Examples provided for IB Services and ISQLMonitor.
762	–
763	–	10. Fix error when writing to blob streams that recorded only the last buffer
764	–	write in the blob stream. In most cases, this did not cause a problem as the
765	–	IB Blob Stream is written in a single write. However, with the TDBImage, write
766	–	of a graphic type prefix was lost which caused a problem when the image could
767	–	not be automatically recognised.
768	–
769	–	11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
770	–	already open" errors due to random numbers used for the cursor name being identical.
771	–
772	–	12. IBTable: corrected error that could result in an "Index out of bounds" error
773	–	when opening the table and the Primary Key is the last or only column in the
774	–	table. Thanks to Rick Hoover for the fix.
775	–
776	–	13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
777	–	of "UTF-8", and update list of available database character sets. Existing
778	–	users should check the current lc_ctype setting in their applications.

781	–
782	–	1.  Firebird Services: avoid List Index error when opening a service with an
783	–	empty Params property.
784	–
785	–	2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
786	–	Link now set up in Loaded method - avoids occasional failure to apply
787	–	SQL markup on initial open.
788	–
789	–	3.  "Employees" example performance improvements when scrolling.
790	–
791	–	4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
792	–	TFrame. Force recaching of selected frame to avoid GTK race (results in a
793	–	random image cached).
794	–
795	–	5.  DBControlGrid: Should now react to changes in panel height at run time.
796	–
797	–	6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
798	–	even when further rows exist.
799	–
800	–	7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
801	–	always be derived from panel height and setting this property can cause confusion.
802	–	Note for existing projects: to avoid a missing property error at run time,
803	–	each form using the DBControlGrid must be opened, updated and saved in the IDE
804	–	in order to remove the property value from the lfm.

808	–
809	–	1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
810	–	call Prepare before setting parameter values.
811	–
812	–	2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
813	–
814	–	3.  Code tidyup and more robust handling of dsql information result vector.
815	–
816	–	4.  Support for centralised handling of transaction status changes. TIBTransaction
817	–	has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
818	–	and "AfterExecQuery". The first three are called after the same event is called
819	–	for an IBCustomDataSet descendent using the Transaction. The fourth is called
820	–	after a call to TIBSQL.ExecQuery, again using this transaction. These new events
821	–	enable monitoring of transaction status changes for a given transaction to be
822	–	handled in a single place. For example, when a change to the dataset occurs
823	–	an indicator can be set that shows the user that in order to save changes,
824	–	the transaction should be committed.  Rather than doing this per dataset, this
825	–	can now be done per transaction.
826	–
827	–	5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
828	–	the dataset is scrolled. However, any changes to the current row are, by default,
829	–	discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
830	–	have a new property "DataSetCloseAction" that adds automatic posting of changes
831	–	on dataset close. If this property is set to dcDiscardChanges (default) then the
832	–	behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
833	–	then IBX will attempt to post any unsaved changes before the dataset is closed
834	–	(and after the BeforeClose event handler is called). The exception is when the
835	–	dataset is being closed as a result of a transaction rollback. In this case,
836	–	no action is taken and any unsaved  changes are discarded. This avoids both
837	–	unnecessary overhead and the risk that a validation error may occur in the Post
838	–	raising an exception and thereby preventing a rollback.
839	–
840	–	6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
841	–	In earlier versions, the Display Width was set to the maximum byte width rather than the character
842	–	width. Display Widths are now corrected by dividing by the max byte width per character.
843	–	For UTF8 character sets, the byte width is four and hence the Display Width will be
844	–	the byte width divided by 4. The byte width of each character set is determined
845	–	dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
846	–	system table. (see also http://bugs.freepascal.org/view.php?id=27766).
847	–
848	–	7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
849	–
850	–	8.  IBLookupComboEditBox: List should now always be restored to full list when the
851	–	control loses focus. Default Key press default interval reduced to 200ms.
852	–
853	–	9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
854	–	when dataset rows are less than visible rows.
855	–
856	–	10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
857	–	does not exist or DataSet is empty. More responsive on dataset open. New event
858	–	OnRestorePosition. Column sort disabled if no header row.
859	–
860	–	11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
861	–	while dataset state is dsInsert. Avoids posting errors.
862	–
863	–	12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
864	–	avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
865	–
866	–	13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
867	–
868	–	14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
869	–	to solve a specific problem. That is when the dataset cursor is moved (e.g. by
870	–	a grid mouse click and the current row is being edited or inserted. In this case, TDataset
871	–	always "posts" the current record regardless or whether or not it may be more appropriate
872	–	to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
873	–	"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
874	–	as the first action of the "Post" method and allows the handler to convert the Post
875	–	into a Cancel if that is the appropriate action on moving to a different row. This is
876	–	achieved by returning with "CancelPost" argument set to true. Note that an exception could be
877	–	raised here, but it may still be more appropriate to validate a post and signal
878	–	a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
879	–
880	–	15. On Unix derived systems, the Firebird library name can now be given as a colon
881	–	separated list. Each library name on the list is tried in turn, in left to right
882	–	order with the first found being used as the firebird library. By default, on Linux,
883	–	the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
884	–	overidden by the FBLIB environment variable or the OnGetLibraryName function.
885	–
886	–	Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
887	–	then it will still attempt to access the database via the Firebird Server and will
888	–	require a username and password. If only the pathname is given, then the username
889	–	and password should be omitted and the unix file permissions are used to grant
890	–	access.

893	–
894	–	1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
895	–	rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
896	–	that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
897	–	corresponds to a row of the linked DataSource. Any data aware control on the
898	–	replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
899	–
900	–	2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
901	–	When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
902	–	takes place during database access. This may be useful when there are performance issues with
903	–	the change of cursor. Setting the property to false suppresses the change of cursor.
904	–
905	–	3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
906	–	and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
907	–	Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
908	–	making all changes permanent immediately rather than when the transaction is explicitly
909	–	committed.
910	–
911	–	4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
912	–	using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

919	–
920	–	1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
921	–	This is typically used during an "OnBeforeOpen" event handler to manipulate the
922	–	"Where" and "Having" clauses to implement user specified filters of arbitrary
923	–	complexity.
924	–
925	–	2. A new Component Palette entry "Firebird Data Controls" is now available. This has
926	–	three new data aware controls dependent on IBX and which make use of the SQL Parser.
927	–	These are:
928	–
929	–	- TIBLookupComboEditBox
930	–	- TIBDynamicGrid
931	–	- TIBTreeview
932	–
933	–	TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
934	–	of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
935	–	to revise the available list and restrict it to items that are prefixed by the
936	–	typed text (either case sensitive or case insensitive). Autoinsert allows a
937	–	newly typed entry to be added to the list dataset and included in the available
938	–	list items.
939	–
940	–	TIBDynamicGrid is a TDBGrid descendent that provides for:
941	–	- automatic resizing of selected columns to fill the available row length
942	–	- automatic positioning and sizing of a "totals" control, typically at the
943	–	column footer, on a per column basis.
944	–	- DataSet resorting on header row click, sorting the dataset by the selected column.
945	–	A second click on the same header cell reversed the sort order.
946	–	- Support for a "Panel Editor". That is on clicking the indicator column, the row
947	–	is automatically expanded and a panel superimposed on it. The panel can have any
948	–	number of child controls, typically data aware controls with the same datasource
949	–	as the grid allowing for editing of additional fields and more complex editors.
950	–	- Reselection of the same row following resorting.
951	–	- A new cell editor that provides the same functionality as TIBLookupComboEditBox.

966	–	repeated multiple times.
967	–
968	–	6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
