3	<	1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to
3	>	1. Add try-..except check when initially loading library in IDE. This should
4	>	ensure that IDE continues to load even when a failure occurs in IBX load
5	>	library.
6	>
7	>	2. IBXScript: now recognises a CASE...END block within a stored procedure and
8	>	hence will correctly detect end of the outer containing block when the block
9	>	contains a SELECT ... CASE ... END construct.
10	>
11	>	3. IBExtract: some further tidying up to remove extraneous white space.
12	>
13	>	4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
14	>	errors when extra elements are added to DB.TFieldType.
15	>
16	>	5. IBUpdate: updated to reflect changes to ISQLParam.
17	>
18	>	6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
19	>
20	>	7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
21	>

23	>
24	>	1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
25	>	exception of those defined to be one byte wide e.g. DBImplementationNo.
26	>
27	>	2. TIBSQL: Batch Update/Insert support added.
28	>
29	>	3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
30	>	is no longer automatically converted to upper case when it is syntactically a
31	>	SQL Identifier. This is to support the use of stored procedures defined e.g.
32	>	as CREATE PROCEDURE "iCASE".
33	>
34	>	There could be a backwards compatibility issue when the StoredProcName was entered
35	>	manually at design time. That is not selected from the drop down list. If the
36	>	StoredProcName is entered in mixed case and the procedure was declared e.g. as
37	>	CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
38	>	ensure that the value of the StoredProcName is all upper case, unless it was
39	>	declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
40	>	quotes).
41	>
42	>	Note that when a stored procedure name was declared delimited in double quotes,
43	>	as in the first example above, the value of the StoredProcName property must not
44	>	include the delimiters (double quotes).
45	>
46	>	4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
47	>	upgrade.conf was not found. This replaces silently ignoring the problem.
48	>
49	>	5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
50	>	'Version.%.3d' and is used to generate the section header names (for a given
51	>	version no.) in the upgrade.conf file.
52	>
53	>	IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
54	>
55	>	1. -c command line option added to fbsql example program. Used to set connection
56	>	character set.
57	>
58	>	IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
59	>
60	>	1. Firebird 4 support added.
61	>
62	>	2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
63	>	extended precision NUMERIC fields are supported.
64	>
65	>	3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
66	>
67	>	4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
68	>	and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
69	>
70	>	5. IBExtract now supports FB4 enhancements:
71	>	- new data types as above
72	>	- Identity column extensions
73	>	- Default user role
74	>	- SQL Security clause for Database, Tables, Procedures, Functions and Triggers
75	>	- Internal Functions
76	>
77	>	6. IBExtract: new event: OnExtractLines.
78	>
79	>	7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
80	>
81	>	8. IBXServices: Server version no. parsing now allows any letter before major version number
82	>	and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
83	>
84	>	9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
85	>	format for rendering a time zone.
86	>
87	>	10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
88	>	to convert TIME WITH TIME ZONE data type values to and from GMT.
89	>
90	>	11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
91	>	IIBGUIInterface and IIBTimerInf respectively.
92	>
93	>	12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
94	>	now accessible as properties of TIBDatabase and TIBTransaction respectively.
95	>
96	>	13. String Fields: when a fixed character with (CHAR) field is returned, it is now
97	>	truncated to its fixed character width rather than being right padded with
98	>	white space to the maximum data size.
99	>
100	>	14. TIBTable.Empty table. In additional to deleting all records in the underlying
101	>	table, the internal buffers are now also flushed ensuring that the TIBTable is
102	>	also empty.
103	>
104	>	15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
105	>
106	>	16. TIBXControlService descendents: DatabaseName may now be set using a database
107	>	connect string. The database name is extracted from the connect string.
108	>
109	>	17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
110	>
111	>	18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
112	>
113	>	19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
114	>	not being present as required.
115	>
116	>	20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
117	>	version that can be customised to work with other database drivers.
118	>
119	>	21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
120	>	unnecessary CR at end of line on Unix platforms.
121	>
122	>	22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
123	>	seconds in order to reduce risk of message loss.
124	>
125	>	23. ISQLMonitor: read and write count statistics now available via:
126	>	property TIBSQLMonitor.ReadCount;
127	>	IIBSQLMonitorHook.GetWriteCount: integer;
128	>
129	>	24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
130	>
131	>	IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
132	>
133	>	1.  TIBStringField: when a string value is read from a dataset buffer, if the
134	>	number of UTF8 characters exceeds the string size then string is truncated
135	>	to the maximum string size. This is  usually a problem with fixed width columns
136	>	right padded with white space.
137	>
138	>	2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
139	>	If SQLFiltered is set then when a dataset is opened, each line in the
140	>	SQLFilterParams property is assumed to be a SQL condition clause and
141	>	ANDed into the Where clause of the SQL Select statement provided as a
142	>	dataset property. Each such SQL condition thus acts as an additional filter
143	>	on the dataset.
144	>
145	>	3.  The Filtered property inherited from TDataset is no longer used for SQL (server
146	>	side filters).
147	>
148	>	4. IBLookupComboEditBox: Selection should no longer reset to start of text when
149	>	text matches complete entry.
150	>
151	>	5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
152	>	dataset are active (avoids risk of access violation if master is inactive)
153	>
154	>	6. TIBEvents: Registered property can now be set at design time even if database not open
155	>
156	>	7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
157	>	This should prevent "spillover" of events between sessions.
158	>
159	>	8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
160	>	This should ensure that the internal buffer is set up correctly and avoids
161	>	a duplicate initial row.
162	>
163	>	9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
164	>	That is, the DataSize should be the field size * character set width. The
165	>	value returned by DataSize is now the same as the Dataset buffer size reserved
166	>	for the field.
167	>
168	>	10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
169	>
170	>	11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
171	>	and vice-versa. This may result in an exception being raised (correctly) for
172	>	older programs when using dataset fields added to a form and the database has been
173	>	upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
174	>	In such cases, the field needs to be deleted in the IDE fields editor and then
175	>	added back in.
176	>
177	>	12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
178	>	false if query contains only white space and not just empty.
179	>
180	>	12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
181	>	should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
182	>	is cancelled.
183	>
184	>	13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
185	>	called on a null field.
186	>
187	>	14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
188	>	results in an empty dataTC86                Client side Filtered Dataset    1       X
189	>	set.
190	>
191	>	15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
192	>	a cached update is applied and an exception is raised.
193	>
194	>	16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
195	>
196	>	17. Console Mode Local Database support: backup/restore should now work correctly.
197	>
198	>	18. Local Database Support: if an upgrade fails, a downgrade is now performed if
199	>	possible and an exception raised.
200	>
201	>	19. MinimumVersionNo added to Local Database Support. Database will not open if
202	>	below this version no. and upgrade not possible.
203	>
204	>	IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
205	>
206	>	1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
207	>	not SQL Identifiers are now supported.
208	>
209	>	2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
210	>	passed to the Firebird engine for execution.
211	>
212	>	3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
213	>	is made to scroll back.
214	>
215	>	4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
216	>
217	>	5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
218	>	only enclosed in double quotes in SQL dialect 3 and when it needs to be.
219	>
220	>	6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
221	>	validated. If no match is found in the list of field names and the database has
222	>	been opened in SQL Dialect 3, then the ListField Name is converted to upper case
223	>	if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
224	>
225	>	7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
226	>	with fpc 3.2.
227	>
228	>	IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
229	>
230	>
231	>	1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
232	>	and is used to override the default settings in the client side "firebird.conf" This
233	>	includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
234	>	Each line of the string list should be a setting in the same format as "firebird.conf".
235	>	For example "WireCompression = true" in order to request wire compression on the client side.
236	>
237	>	Note: explicit settings in the client side "firebird.conf" appear to take precedence
238	>	over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
239	>	also require a compatible setting in the server side "firebird.conf". For example
240	>	"WireCompression = true" must also be set in the server's "firebird.conf" for wire
241	>	compression to be used.
242	>
243	>	Whether or not WireCompression or WireCrypt are in use can be checked using the information
244	>	returned with the Client/Server protocol version. See ibx/examples/dbadmin and
245	>	ibx/examples/dbinfo for examples of how to display this information.
246	>
247	>	2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
248	>	is a "convenience" property. If set the "WireCompression=true" is added to the
249	>	ConfigOverrides. If unchecked then this setting is removed.
250	>
251	>	3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
252	>	not "INT64".
253	>
254	>	4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
255	>	These are:
256	>	property TimestampFormat: string;
257	>	property DateFormat: string;
258	>	property TimeFormat: string;
259	>
260	>	Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
261	>	DATETIME and TIME. The format strings use the standard FPC date/time format
262	>	characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
263	>
264	>	If any of the above properties are set to an empty string, then the locale default
265	>	is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
266	>	locale default is extended by appending '.zzz' to include milliseconds.
267	>
268	>	TIBCSVDataOut by default sets these properties to the empty string, while the other
269	>	two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
270	>
271	>	5. New published property for TIBCSVDataOut:
272	>	property QuoteStrings: boolean (default true)
273	>
274	>	If false then strings are unquoted, otherwise, the QuoteChar property value is
275	>	used to delimit each and every string in the output.
276	>
277	>	6. New published properties for TIBCSVDataOut:
278	>	property FieldSeparator: string;
279	>	property HeaderSeparator: string;
280	>
281	>	Respectively, these provide the separator character(s) used to separate fields
282	>	in data and header rows. Both default to ','.
283	>
284	>	7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
285	>	TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
286	>	property OnFormatTextString;
287	>
288	>	This event handler can be used to process text strings before they are included
289	>	in the output e.g. to replace unprintable characters with alternative strings.
290	>	This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
291	>
292	>	8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
293	>	Uses "FindParam" if in order to find out if a parameter with a given name exists
294	>	and without raising and exception if it does not.
295	>
296	>	9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
297	>	consistency with SQL queries.
298	>
299	>	10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
300	>	When true, SQL statement parameter names are parsed case sensitive. Note for
301	>	TIBDataSet only applies to Select query.
302	>
303	>	11. IBEvents: removing a TIBEvent component from a form should no longer result in
304	>	an IDE exception.
305	>
306	>	12. LocalDBSupport: initial database creation should now work correctly
307	>	when the schema source is an sql file.
308	>
309	>	13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
310	>	when defined, this handler will be called by the internal TIBXScript during
311	>	initial database creation when the schema source is an sql file and may be used
312	>	to provide a visual indication of progress in console mode.
313	>
314	>	14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
315	>	to true while a new local database is being created and its schema populated.
316	>	Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
317	>	when the database is disconnected/connected during the create DB procedure.
318	>
319	>	15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
320	>	are now always ignored and replaced by the user name and password provided as
321	>	the login parameters for the TIBDatabase referenced from the TIBXScript. The
322	>	IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
323	>	completely ignored if this property is true.
324	>
325	>	16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
326	>	to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
327	>	ImageIndex and SelectImageIndex values on AddNode.
328	>
329	>	17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
330	>	read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
331	>	the same database connection.
332	>
333	>	18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
334	>	if provided, this should be an conditional SQL expression suitable for
335	>	including in an SQL Select statement "where" clause. If non-empty and the
336	>	"Filtered" property is true then the SQL expression provided as the value of
337	>	the "Filter" property is "ANDed" with any existing condition statement
338	>	in the SQL statement's "Where" clause.
339	>
340	>	If the "Filter" property is set at run time, the "Filtered" property is true
341	>	and the dataset is already open, then the dataset is closed and re-opened automatically.
342	>
343	>	The "Filter" condition may include IBX style parameters. In which case, their
344	>	value must be set by the dataset's "OnBeforeOpen" event handler.
345	>
346	>	This is a public property for TIBDataSet and TIBQuery query and intended for
347	>	use at run time.
348	>
349	>	Note: The property is a published property of TIBTable. The TIBTable functionality
350	>	is unaffected by this change.

352	>	IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
353	>
354	>	1. Remove need to check for IsMultiThread by providing access to GUI timers via
355	>	IBGUIInterface. Note: master/detail delay timer does not apply to console
356	>	mode apps.
357	>
358	>	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
359	>	statement. This avoids problems if "Execute Block" is used as the Query.
360	>
361	>	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
362	>	internal SQL tokeniser routines.
363	>
364	>	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
365	>	as a select statement, with or without CTEs.
366	>
367	>	5. IBSQLParser: parser now recognises the "ROWS" clause.
368	>
369	>	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
370	>	internal SQL tokeniser routines.
371	>
372	>	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
373	>	being raised for valid set statements processed by a data formatter.
374	>
375	>	8. New published property for TIBDatabase and TIBXServicesConnection. This is
376	>	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
377	>	the path of the Firebird Library used by the database/services connection.
378	>
379	>	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
380	>	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
381	>	services connection.
382	>
383	>	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
384	>	or param name is not a valid SQL identifier.
385	>
386	>	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
387	>	view of whether the text box should be editable when no DataSource is specified.
388	>	TIBLookupComboEditBox has been updated to workaround this problem. As long as
389	>	ReadOnly is false, the text box is editable when no DataSource is specified.
390	>
391	>	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
392	>	the FBLIB environment variable. If you do not want to permit this then you
393	>	must modify the Register procedure in the design/IBDBReg.pas unit to remove
394	>	this setting.

406	>	The IBX packages used by most users have not changed, with one exception. The
407	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
408	>	to use the IBServices unit in your applications, please add the iblegacyServices
409	>	to the list of dependencies. To do this, open the Project Inspector and select
410	>	Add->New Requirement and select "ibLegacyServices" from the list of available
411	>	packages.
412	>
413	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
414	>	the IBServices unit providing what is intended to be a clearer and easier to
415	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
416	>	more information and the guide to "Firebird Service Management Using IBX".
417	>	As indicated above, the legacy services components are still available and
418	>	provided in a separate package. There is no need to update working applications
419	>	using the older versions except for an additional package dependency.
420	>
421	>	2. The IBX packages and source code tree have been re-organised in an attempt to
422	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
423	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
424	>	new set of IBX packages.
425	>
426	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
427	>	updated to use the new Services API components.
428	>
429	>	4. The iblocal package has been updated to use the new Services API components.
430	>
431	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
432	>	TIBXSecurityService. It had been wrongly classified in the previous version
433	>	as a per database configuration item. It is global to a server and hence
434	>	correctly positioned as part of the Security Package. In the DBAdmin example,
435	>	the setting has moved to the mappings page.
436	>
437	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
438	>	are ignored.
439	>
440	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
441	>	closed before the database is dropped. Before and After Disconnect event handlers
442	>	are also fired.
443	>
444	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
445	>	is started and not just the first time.
446	>
447	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
448	>	depenendency with comp type.
449	>
450	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
451	>
452	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
453	>	then this is recognised and not ignored.
454	>
455	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
456	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
457	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
458	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
459	>
460	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
461	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
462	>	counters for the select query. Note: stats accumulate after each fetch from
463	>	the database. To get total query cost after open, call the "Last" method
464	>	and then GetPerfStatistics.
465	>
466	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
467	>
468	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
469	>	in parenthesises.
470	>
471	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
472	>	SQL identifiers are always delimited by double quotes. If false, then they are
473	>	only delimited if the identifier is a reserved word, contains lower case or special
474	>	characters. Set this property to true to retain previous behaviour.
475	>
476	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
477	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
478	>
479	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
480	>	property MasterDetailDelay: integer {defaults to zero}
481	>
482	>	When non-zero and the dataset is a detail table referencing a master table
483	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
484	>	then a synchronisation delay is added (in milliseconds) between the master
485	>	row changing and the detail dataset being re-opened. If the master dataset
486	>	is scrolled before the delay expires then the delay is reset. This can be used
487	>	to avoid performance overheads when scrolling through a large master dataset.
488	>
489	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
490	>	chreads unit must be included in your project. TTimer is not used in order
491	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
492	>
493	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
494	>	with Extract Option eoDatabase.
495	>
496	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
497	>	When a deLayoutChanged event is reported on the ListSource dataset, the
498	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
499	>	relationship with the control's datasource (master).
500	>
501	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
502	>
503	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
504	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
505	>
506	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
507	>	DDL (Firebird 3 and later only).
508	>
509	>	22. TIBLookupComboBox Autocomplete Fixes:
510	>	i. Only appended text is now selected after autocomplete.
511	>	ii. Uppercase keys no longer ignored for autocomplete.
512	>	iii. Retain Prefix case is now honoured correctly.
513	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
514	>	before autocomplete performed. i.e. behaviour now the same as when
515	>	no DataSource assigned.
516	>
517	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
518	>	between SQL statements.
519	>
520	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
521	>	ObjectNames are converted to upper case before matching against metadata object
522	>	names, unless the objectname is delimited by double quotes, in which case, the
523	>	double quotes are removed and the remaining string is used (unmodified) to match
524	>	against the metadata object name.
525	>
526	>	If true then the ObjectName is used as is without modification and matched
527	>	against the metadata object name. No attempt is made to remove double quotes.
528	>
529	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
530	>	with eoTrigger, these extract types can be used to select only Database Triggers,
531	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
532	>
533	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
534	>	statement separate character is now reset to the default (';').
535	>
536	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
537	>
538	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
539	>	a commit or reconnect statement and instead activated only when next SQL statement
540	>	is executed.
541	>
542	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
543	>
544	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
545	>	converting statement to upper case.
546	>
547	>	31. TIBExtract: metadata comments now supported. New published property
548	>	IncludeMetaDataComments (default true). If true then metadata comments included
549	>	in extracted DDL. New Extract Object member eoComments. This may be used with
550	>	ExtractObject method to list all metadata comments.
551	>
552	>	32. TIBExtract: ListObjectNames method added.
553	>
554	>	33. Updated Database component editor to support additional connection string
555	>	types.
556	>
557	>	IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
558	>
559	>	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
560	>	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
561	>	RELEASE.
562	>
563	>	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
564	>
565	>	1. IBExtract: Identity columns - add additional check for null column for generator name.
566	>
567	>	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
568	>	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
569	>	information). However, this is also a very useful mechanism for returning updated computed by
570	>	column values. Values returned as a result of executing an Insert or Update statement
571	>	replace existing values in the current row for each corresponding column.
572	>
573	>	Previously, if a dataset's select query included read only (computed by) fields then
574	>	an automatic row refresh was performed after an insert or update query had been processed,
575	>	irrespective of the setting of the "ForcedUpdates" property. This has changed such
576	>	that an automatic refresh is no longer performed if an insert or update query contains
577	>	a returning clause that updates one or more fields on the current row. A full row
578	>	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
579	>	field values and the select query contains read only fields. Use of Insert/update
580	>	returning should be significantly more efficient than executing a refresh query.
581	>
582	>	This behaviour change is intended to be backwards compatible and there should be no need to change
583	>	existing programs, other than to improve performance by using the new capability.
584	>
585	>	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
586	>	they are called when the dataset row is being deleted, there is no value in
587	>	updating the current record from the query result. Instead, a new event handler
588	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
589	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
590	>	by the query. The event handler can then interrogate the query results and
591	>	perform whatever action is necessary. For example to confirm, to the user,
592	>	the deletion of a row with the returned values.
593	>
594	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
595	>	any Computed By or Identity Columns. The IBTables example has been updated to
596	>	illustrate the computation of the employee Full Name on update.
597	>
598	>	5. TIBTable: The GeneratorField property is now published.
599	>
600	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
601	>	When InsertSQL is generated, the Identity columns are not included in the list of values to
602	>	be inserted. A RETURNING clause is added to the insert statement to return the value of
603	>	each Identity column after the insert is executed.
604	>
605	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
606	>	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
607	>	Insert..Returning clause.
608	>
609	>	8. TIBGenerator: small performance improvement by not preparing query each time
610	>	a new value is generated.
611	>
612	>	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
613	>
614	>	10. Property editors will now sync table name to a System Table when "Include System
615	>	Tables" is selected and the query is for a System Table.
616	>
617	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
618	>	values are no longer converted to milliseconds from TDateTime and then back again
619	>	to TDateTime (the conversion to milliseconds is the default TDataset approach).
620	>
621	>	12. Property Editors handling of Stored Procedures.
622	>	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
623	>	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
624	>	query).
625	>	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
626	>
627	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
628	>	can be used to select a package. If non-empty, the stored procedure name is
629	>	expected to be a stored procedure defined in the specified package and the
630	>	generated SQL will be as required for a stored procedure located in a package.
631	>
632	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
633	>	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
634	>	which a stored procedure can be selected. With no package name selected, non-package
635	>	stored procedures are listed.
636	>
637	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
638	>	for password on reconnect.
639	>
640	>	16. TIBDatabase: use IAttachment for connection default character set id, code page
641	>	and character set name.
642	>
643	>	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
644	>	DB info lookups"
645	>
646	>	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
647	>
648	>	19. Add a property Editor for TIBUpdate.RefreshSQL.
649	>
650	>	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
651	>	parameters. This stops an exception being raised when the field cannot be
652	>	located in the record buffer.
653	>
654	>	21. Property Editors now automatically include System Tables when opened and when the query table
655	>	is a System Table.
656	>
657	>	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
658	>	This avoids errors due to a stale SQRB or SRB being used for the next query.
659	>
660	>	23. IBServices: Service attach parameters now include "expected_db". This is used to
661	>	add the SPB item isc_spb_expected_db. This names a database using
662	>	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
663	>	database. examples/services re-written to illustrate use of "expected_db".
664	>
665	>	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
666	>	This avoids truncated backups when the server returns a timeout (busy) response.
667	>
668	>	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
669	>
670	>	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
671	>	databasenames. These are respectively expanded to the local system's temp directory
672	>	(including trailing delimiter) or to a prescribed data directory (including
673	>	trailing delimiter). Under Unix systems the data directory is a hidden directory
674	>	in the user's home directory. The hidden directory name is either the string returned
675	>	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
676	>	Under Windows, the directory is the same as the Data Directory as decribed
677	>	above but instead prefixed by the User's application data path. These may be
678	>	used to improve application portability for Personal Databases.
679	>
680	>	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
681	>	this has not worked for a long time and is not useful either. FieldDefs should be
682	>	managed using the Fields Editor as with any other dataset. To access the fields
683	>	editor for a TIBTable component, double click on the component. The fields editor
684	>	is then displayed.
685	>
686	>	28. TIBDatabaseInfo: new properties/function
687	>	* DateDBCreated (returns date/time database created)
688	>	* TransactionCount (returns no. of active transactions)
689	>	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
690	>	* PagesFree (Firebird 3 or later)
691	>	* PagesUsed (Firebird 3 or later)
692	>	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
693	>	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
694	>
695	>	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
696	>
697	>	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
698	>
699	>	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
700	>	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
701	>
702	>	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
703	>	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
704	>	firing during backup and restore.
705	>
706	>	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
707	>	for verbose output using the new property "StatisticsRequested".
708	>	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
709	>
710	>	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
711	>
712	>	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
713	>	palette. This uses the online validation feature added in Firebird 2.5. The
714	>	services's properties enable inclusion/exclusion of tables and indexes using
715	>	regular expressions. See.
716	>	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
717	>
718	>	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
719	>	option on a database.
720	>
721	>	37. TIBCustomService: Assign method implemented to allow copying of service login
722	>	context between service API components. "Detach" method now only detaches
723	>	service when last reference to the service interface detaches. Tidy up of
724	>	code for SetActive and Attach methods including password hiding.
725	>
726	>	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
727	>	and used to determine the auth method and protocol used for the connection.
728	>
729	>	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
730	>	a Create Database Statement generated by IBX.
731	>
732	>	40. All IBServices now have an additional published property "PortNo". This may
733	>	be set to a non-standard port number when necessary. If zero then the default
734	>	port number is used.
735	>
736	>	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
737	>	and not just the mouse.
738	>
739	>	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
740	>
741	>	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
742	>	image index and selected image index for each node to be set from a database field.
743	>
744	>	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
745	>	then database schema includes grants to all users. If not present then the
746	>	only user grants included are those to User PUBLIC.
747	>
748	>	45. TIBTreeView: performance improvement. When expanding include both expanded node
749	>	and child nodes in dataset.
750	>

753	>
754	>	1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
755	>	changes.
756	>
757	>	2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
758	>	Bug could result in truncated multi-byte character set values.
759	>
760	>	3. Changes consequential on moving fbintf character set utility functions from
761	>	IFirebirdAPI to IAttachment.
762	>
763	>	4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
764	>
765	>	5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
766	>	results in autocomplete ignoring prefix text.
767	>
768	>	6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
769	>	entering a new name into the text box.
770	>
771	>	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
772	>	Firebird rather than recomputing it.
773	>
774	>	8. Property Editor positioning tidy up: All IBX Property editors should now be
775	>	screen centre. Previously some were "poDesigned" which may be inappropriate
776	>	for multi monitor desktops.
777	>
778	>	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
779	>
780	>	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
781	>	a transaction and always reset the object.
782	>
783	>	12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
784	>
785	>	13. TIBXScript: Allow for override of database filename in Create Database statements.
786	>
787	>	14. IBLocaldb: Support initialisation of the database from an SQL script in addition
788	>	to a gbak format archive.
789	>
790	>	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
791	>
792	>	16. IBLocaldb: Drop database if error creating an empty database.
793	>
794	>	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
795	>	unless selected node not in current dataset.
796	>
797	>	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
798	>	to TIBCustomService, and IBlocalDB code tidy up.
799	>
800	>	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
801	>	behaviour due to uninitialised variable.
802	>
803	>	20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
804	>	integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
805	>
806	>	21. IBSQL: When Database changed ensure that all resources are freed.
807	>
808	>	22. IBCustomDataset: When database changed ensure that queries an unprepared.
809	>
810	>	23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
811	>	* Line Wrap on SQL Token boundaries (on user command)
