3	>	1. Remove need to check for IsMultiThread by providing access to GUI timers via
4	>	IBGUIInterface. Note: master/detail delay timer does not apply to console
5	>	mode apps.
6	>
7	>	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
8	>	statement. This avoids problems if "Execute Block" is used as the Query.
9	>
10	>	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
11	>	internal SQL tokeniser routines.
12	>
13	>	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
14	>	as a select statement, with or without CTEs.
15	>
16	>	5. IBSQLParser: parser now recognises the "ROWS" clause.
17	>
18	>	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
19	>	internal SQL tokeniser routines.
20	>
21	>	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
22	>	being raised for valid set statements processed by a data formatter.
23	>
24	>	8. New published property for TIBDatabase and TIBXServicesConnection. This is
25	>	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
26	>	the path of the Firebird Library used by the database/services connection.
27	>
28	>	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
29	>	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
30	>	services connection.
31	>
32	>	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
33	>	or param name is not a valid SQL identifier.
34	>
35	>	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
36	>	view of whether the text box should be editable when no DataSource is specified.
37	>	TIBLookupComboEditBox has been updated to workaround this problem. As long as
38	>	ReadOnly is false, the text box is editable when no DataSource is specified.
39	>
40	>	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
41	>	the FBLIB environment variable. If you do not want to permit this then you
42	>	must modify the Register procedure in the design/IBDBReg.pas unit to remove
43	>	this setting.

51	>
52	>	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
53	>	all previous copies of the IBX source code tree before installing this release.
54	>
55	>	The IBX packages used by most users have not changed, with one exception. The
56	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
57	>	to use the IBServices unit in your applications, please add the iblegacyServices
58	>	to the list of dependencies. To do this, open the Project Inspector and select
59	>	Add->New Requirement and select "ibLegacyServices" from the list of available
60	>	packages.
61	>
62	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
63	>	the IBServices unit providing what is intended to be a clearer and easier to
64	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
65	>	more information and the guide to "Firebird Service Management Using IBX".
66	>	As indicated above, the legacy services components are still available and
67	>	provided in a separate package. There is no need to update working applications
68	>	using the older versions except for an additional package dependency.
69	>
70	>	2. The IBX packages and source code tree have been re-organised in an attempt to
71	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
72	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
73	>	new set of IBX packages.
74	>
75	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
76	>	updated to use the new Services API components.
77	>
78	>	4. The iblocal package has been updated to use the new Services API components.
79	>
80	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
81	>	TIBXSecurityService. It had been wrongly classified in the previous version
82	>	as a per database configuration item. It is global to a server and hence
83	>	correctly positioned as part of the Security Package. In the DBAdmin example,
84	>	the setting has moved to the mappings page.
85	>
86	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
87	>	are ignored.
88	>
89	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
90	>	closed before the database is dropped. Before and After Disconnect event handlers
91	>	are also fired.
92	>
93	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
94	>	is started and not just the first time.
95	>
96	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
97	>	depenendency with comp type.
98	>
99	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
100	>
101	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
102	>	then this is recognised and not ignored.
103	>
104	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
105	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
106	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
107	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
108	>
109	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
110	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
111	>	counters for the select query. Note: stats accumulate after each fetch from
112	>	the database. To get total query cost after open, call the "Last" method
113	>	and then GetPerfStatistics.
114	>
115	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
116	>
117	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
118	>	in parenthesises.
119	>
120	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
121	>	SQL identifiers are always delimited by double quotes. If false, then they are
122	>	only delimited if the identifier is a reserved word, contains lower case or special
123	>	characters. Set this property to true to retain previous behaviour.
124	>
125	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
126	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
127	>
128	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
129	>	property MasterDetailDelay: integer {defaults to zero}
130	>
131	>	When non-zero and the dataset is a detail table referencing a master table
132	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
133	>	then a synchronisation delay is added (in milliseconds) between the master
134	>	row changing and the detail dataset being re-opened. If the master dataset
135	>	is scrolled before the delay expires then the delay is reset. This can be used
136	>	to avoid performance overheads when scrolling through a large master dataset.
137	>
138	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
139	>	chreads unit must be included in your project. TTimer is not used in order
140	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
141	>
142	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
143	>	with Extract Option eoDatabase.
144	>
145	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
146	>	When a deLayoutChanged event is reported on the ListSource dataset, the
147	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
148	>	relationship with the control's datasource (master).
149	>
150	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
151	>
152	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
153	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
154	>
155	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
156	>	DDL (Firebird 3 and later only).
157	>
158	>	22. TIBLookupComboBox Autocomplete Fixes:
159	>	i. Only appended text is now selected after autocomplete.
160	>	ii. Uppercase keys no longer ignored for autocomplete.
161	>	iii. Retain Prefix case is now honoured correctly.
162	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
163	>	before autocomplete performed. i.e. behaviour now the same as when
164	>	no DataSource assigned.
165	>
166	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
167	>	between SQL statements.
168	>
169	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
170	>	ObjectNames are converted to upper case before matching against metadata object
171	>	names, unless the objectname is delimited by double quotes, in which case, the
172	>	double quotes are removed and the remaining string is used (unmodified) to match
173	>	against the metadata object name.
174	>
175	>	If true then the ObjectName is used as is without modification and matched
176	>	against the metadata object name. No attempt is made to remove double quotes.
177	>
178	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
179	>	with eoTrigger, these extract types can be used to select only Database Triggers,
180	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
181	>
182	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
183	>	statement separate character is now reset to the default (';').
184	>
185	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
186	>
187	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
188	>	a commit or reconnect statement and instead activated only when next SQL statement
189	>	is executed.
190	>
191	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
192	>
193	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
194	>	converting statement to upper case.
195	>
196	>	31. TIBExtract: metadata comments now supported. New published property
197	>	IncludeMetaDataComments (default true). If true then metadata comments included
198	>	in extracted DDL. New Extract Object member eoComments. This may be used with
199	>	ExtractObject method to list all metadata comments.
200	>
201	>	32. TIBExtract: ListObjectNames method added.
202	>
203	>	33. Updated Database component editor to support additional connection string
204	>	types.
205	>
206	>	IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
207	>
208	>	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
209	>	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
210	>	RELEASE.
211	>
212	>	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
213	>
214	>	1. IBExtract: Identity columns - add additional check for null column for generator name.
215	>
216	>	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
217	>	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
218	>	information). However, this is also a very useful mechanism for returning updated computed by
219	>	column values. Values returned as a result of executing an Insert or Update statement
220	>	replace existing values in the current row for each corresponding column.
221	>
222	>	Previously, if a dataset's select query included read only (computed by) fields then
223	>	an automatic row refresh was performed after an insert or update query had been processed,
224	>	irrespective of the setting of the "ForcedUpdates" property. This has changed such
225	>	that an automatic refresh is no longer performed if an insert or update query contains
226	>	a returning clause that updates one or more fields on the current row. A full row
227	>	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
228	>	field values and the select query contains read only fields. Use of Insert/update
229	>	returning should be significantly more efficient than executing a refresh query.
230	>
231	>	This behaviour change is intended to be backwards compatible and there should be no need to change
232	>	existing programs, other than to improve performance by using the new capability.
233	>
234	>	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
235	>	they are called when the dataset row is being deleted, there is no value in
236	>	updating the current record from the query result. Instead, a new event handler
237	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
238	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
239	>	by the query. The event handler can then interrogate the query results and
240	>	perform whatever action is necessary. For example to confirm, to the user,
241	>	the deletion of a row with the returned values.
242	>
243	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
244	>	any Computed By or Identity Columns. The IBTables example has been updated to
245	>	illustrate the computation of the employee Full Name on update.
246	>
247	>	5. TIBTable: The GeneratorField property is now published.
248	>
249	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
250	>	When InsertSQL is generated, the Identity columns are not included in the list of values to
251	>	be inserted. A RETURNING clause is added to the insert statement to return the value of
252	>	each Identity column after the insert is executed.
253	>
254	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
255	>	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
256	>	Insert..Returning clause.
257	>
258	>	8. TIBGenerator: small performance improvement by not preparing query each time
259	>	a new value is generated.
260	>
261	>	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
262	>
263	>	10. Property editors will now sync table name to a System Table when "Include System
264	>	Tables" is selected and the query is for a System Table.
265	>
266	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
267	>	values are no longer converted to milliseconds from TDateTime and then back again
268	>	to TDateTime (the conversion to milliseconds is the default TDataset approach).
269	>
270	>	12. Property Editors handling of Stored Procedures.
271	>	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
272	>	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
273	>	query).
274	>	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
275	>
276	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
277	>	can be used to select a package. If non-empty, the stored procedure name is
278	>	expected to be a stored procedure defined in the specified package and the
279	>	generated SQL will be as required for a stored procedure located in a package.
280	>
281	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
282	>	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
283	>	which a stored procedure can be selected. With no package name selected, non-package
284	>	stored procedures are listed.
285	>
286	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
287	>	for password on reconnect.
288	>
289	>	16. TIBDatabase: use IAttachment for connection default character set id, code page
290	>	and character set name.
291	>
292	>	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
293	>	DB info lookups"
294	>
295	>	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
296	>
297	>	19. Add a property Editor for TIBUpdate.RefreshSQL.
298	>
299	>	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
300	>	parameters. This stops an exception being raised when the field cannot be
301	>	located in the record buffer.
302	>
303	>	21. Property Editors now automatically include System Tables when opened and when the query table
304	>	is a System Table.
305	>
306	>	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
307	>	This avoids errors due to a stale SQRB or SRB being used for the next query.
308	>
309	>	23. IBServices: Service attach parameters now include "expected_db". This is used to
310	>	add the SPB item isc_spb_expected_db. This names a database using
311	>	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
312	>	database. examples/services re-written to illustrate use of "expected_db".
313	>
314	>	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
315	>	This avoids truncated backups when the server returns a timeout (busy) response.
316	>
317	>	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
318	>
319	>	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
320	>	databasenames. These are respectively expanded to the local system's temp directory
321	>	(including trailing delimiter) or to a prescribed data directory (including
322	>	trailing delimiter). Under Unix systems the data directory is a hidden directory
323	>	in the user's home directory. The hidden directory name is either the string returned
324	>	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
325	>	Under Windows, the directory is the same as the Data Directory as decribed
326	>	above but instead prefixed by the User's application data path. These may be
327	>	used to improve application portability for Personal Databases.
328	>
329	>	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
330	>	this has not worked for a long time and is not useful either. FieldDefs should be
331	>	managed using the Fields Editor as with any other dataset. To access the fields
332	>	editor for a TIBTable component, double click on the component. The fields editor
333	>	is then displayed.
334	>
335	>	28. TIBDatabaseInfo: new properties/function
336	>	* DateDBCreated (returns date/time database created)
337	>	* TransactionCount (returns no. of active transactions)
338	>	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
339	>	* PagesFree (Firebird 3 or later)
340	>	* PagesUsed (Firebird 3 or later)
341	>	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
342	>	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
343	>
344	>	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
345	>
346	>	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
347	>
348	>	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
349	>	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
350	>
351	>	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
352	>	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
353	>	firing during backup and restore.
354	>
355	>	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
356	>	for verbose output using the new property "StatisticsRequested".
357	>	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
358	>
359	>	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
360	>
361	>	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
362	>	palette. This uses the online validation feature added in Firebird 2.5. The
363	>	services's properties enable inclusion/exclusion of tables and indexes using
364	>	regular expressions. See.
365	>	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
366	>
367	>	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
368	>	option on a database.
369	>
370	>	37. TIBCustomService: Assign method implemented to allow copying of service login
371	>	context between service API components. "Detach" method now only detaches
372	>	service when last reference to the service interface detaches. Tidy up of
373	>	code for SetActive and Attach methods including password hiding.
374	>
375	>	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
376	>	and used to determine the auth method and protocol used for the connection.
377	>
378	>	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
379	>	a Create Database Statement generated by IBX.
380	>
381	>	40. All IBServices now have an additional published property "PortNo". This may
382	>	be set to a non-standard port number when necessary. If zero then the default
383	>	port number is used.
384	>
385	>	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
386	>	and not just the mouse.
387	>
388	>	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
389	>
390	>	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
391	>	image index and selected image index for each node to be set from a database field.
392	>
393	>	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
394	>	then database schema includes grants to all users. If not present then the
395	>	only user grants included are those to User PUBLIC.
396	>

403	>	1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
404	>	changes.
405	>
406	>	2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
407	>	Bug could result in truncated multi-byte character set values.
408	>
409	>	3. Changes consequential on moving fbintf character set utility functions from
410	>	IFirebirdAPI to IAttachment.
411	>
412	>	4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
413	>
414	>	5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
415	>	results in autocomplete ignoring prefix text.
416	>
417	>	6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
418	>	entering a new name into the text box.
419	>
420	>	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
421	>	Firebird rather than recomputing it.
422	>
423	>	8. Property Editor positioning tidy up: All IBX Property editors should now be
424	>	screen centre. Previously some were "poDesigned" which may be inappropriate
425	>	for multi monitor desktops.
426	>
427	>	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
428	>
429	>	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
430	>	a transaction and always reset the object.
431	>
432	>	12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
433	>
434	>	13. TIBXScript: Allow for override of database filename in Create Database statements.
435	>
436	>	14. IBLocaldb: Support initialisation of the database from an SQL script in addition
437	>	to a gbak format archive.
438	>
439	>	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
440	>
441	>	16. IBLocaldb: Drop database if error creating an empty database.
442	>
443	>	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
444	>	unless selected node not in current dataset.
445	>
446	>	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
447	>	to TIBCustomService, and IBlocalDB code tidy up.
448	>
449	>	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
450	>	behaviour due to uninitialised variable.
451	>
452	>	20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
453	>	integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
454	>
455	>	21. IBSQL: When Database changed ensure that all resources are freed.
456	>
457	>	22. IBCustomDataset: When database changed ensure that queries an unprepared.
458	>
459	>	23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
460	>	* Line Wrap on SQL Token boundaries (on user command)
461	>	* auto-complete table names in drop down list of table names
462	>	* Double click on tablename or field name adds to SQL text
463	>
464	>	24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
465	>
466	>	25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
467	>	TVariantArray. Seems to avoid memory corruption in Windows (probably a
468	>	workaround for a problem in fpc 3.0.4 win64).
469	>
470	>	26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
471	>
472	>	27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

476	>	1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
477	>	include remote system name.
478	>
479	>	2. TIBExtract: No longer include comment header and COMMIT statement for empty
480	>	tables when data included in output.
481	>
482	>	3. Profiling: IBSQL now has conditional compilation flags to enable query performance
483	>	and timing information to be written to stdout. This may be used to locate
484	>	performance bottlenecks.
485	>
486	>	4. SQLParser: only call "OnChanging" event handler when value is different.
487	>
488	>	5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
489	>
490	>	6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
491	>	that BindFields is called when the query is next activated. Avoids FieldName
492	>	not found error.
493	>
494	>	7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
495	>	purpose and allows the programmer to define any action they want for Update, Insert
496	>	or Delete. This may be complex SQL (similar to a Trigger), application specific
497	>	filtering of updates, or use of statements such as Grant or Revoke instead of
498	>	normal DML. See User Manual for more information.

512	>	5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
513	>	grants to these objects.
514	>
515	>	6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
516	>	dependency problems restoring complex databases.
517	>
518	>	7. TIBXScript: This component has been restructured to allow for the processing of
519	>	embedded XML in INSERT statements and to support interactive sources in addition
520	>	to non-interactive data sources such as files.
521	>
522	>	8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
523	>
524	>	9. TIBXScript: ISQL compatiable Set statements are now supported:
525	>	SET SQL DIALECT
526	>	SET TERM
527	>	SET AUTODDL
528	>	SET BAIL
529	>	SET ECHO
530	>	SET COUNT
531	>	SET STATS
532	>	SET NAMES <character set>
533	>
534	>	10. IBVersion unit added to hold current IBX Version Number information.
535	>
536	>	11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
537	>	and domain definitions.
538	>
539	>	12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
540	>	fully supported.
541	>
542	>	13. TIBExtract: when a database dump includes data, the generator values are now also set.
543	>
544	>	14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

550	>
551	>	1. Size property of TIBStringField is now the width in characters of the field
552	>	and not the byte length. This applies only to multi-byte character sets such
553	>	as UTF8. The original approach aligned with TStringField. However, the TStringField
554	>	code is not recognised as a bug and hence this change to align the behaviour.
555	>	The TStringField change is expected in fpc 3.2.0.
556	>
557	>	2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
558	>	true (default) then Size property value saved in the lfm is ignored. Size is
559	>	always set from the dynamic information read from the database. It is unclear
560	>	why anyone would want to override this and set Size to false.
561	>
562	>	3. ibxscript: should now handle correctly a Case..End statement within a procedure
563	>	block.
564	>
565	>	4. IBDatabase: new property - CreateIfNotExists. If true and database does not
566	>	exist when an attempt is made to connect to it (run time only) then an attempt
567	>	is made to create the database.
568	>
569	>	5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
570	>	has been successfully created as a result of a call to CreateDatabase or when
571	>	creating a database after it was found not to exist.
572	>
573	>	6.  DBControlGrid: a race condition could result in the wrong row image being
574	>	written to the cache. This has been avoided by a trip round the message
575	>	loop before rendering the row image.
576	>
577	>	7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
578	>	a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
579	>	known to risk corrupt rendering of row images when the control is first
580	>	displayed. If necessary use "Application.QueueAsyncCall" to delay opening
581	>	of the dataset (see DBControlGrid examples) until the Form's Window has been created.
582	>
583	>	8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
584	>	a TDateEdit control located on an editor panel.
585	>
586	>	9.  TIBExtract: brought up-to-date plus many bug fixes.
587	>
588	>	10. DBControlGrid: Removed memory leak when updating rows.
589	>
590	>	11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

594	>	1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
595	>	when target codepage is CP_NONE. This is a workaround for
596	>	http://bugs.freepascal.org/view.php?id=30622.
597	>
598	>	2. DBLog option removed from TIBStatisticalService - not supported by server
599	>	since Firebird 1.5.
600	>
601	>	3. ibxscript: An error is no longer generated for "on commit preserve rows" or
602	>	similar.
603	>
604	>	4. IBCodePage: updated mapping between codepages and character id.
605	>
606	>	5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
607	>	Firebird. Character sets with a char width of two are not UTF16.
608	>
609	>	6. Strings received from the database are now always transliterated into UTF8
610	>	regardless of the database character set or connection character set. This
611	>	is for compatibility with the LCL.

615		1. IBBlob: Defer reading of blob until read method called. This avoids having to
616		read in an entire blob just to get the size of the blob. General performance
