5	>	1. New property for TIBDatabase and TIBXServicesConnection. This is "WireCompression".
6	>	If this property is set to true then the Client will request WireCompression for
7	>	the connection. Note: "WireCompression = true" must be set in the server's

13	>	1. Remove need to check for IsMultiThread by providing access to GUI timers via
14	>	IBGUIInterface. Note: master/detail delay timer does not apply to console
15	>	mode apps.
16	>
17	>	2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
18	>	statement. This avoids problems if "Execute Block" is used as the Query.
19	>
20	>	3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
21	>	internal SQL tokeniser routines.
22	>
23	>	4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
24	>	as a select statement, with or without CTEs.
25	>
26	>	5. IBSQLParser: parser now recognises the "ROWS" clause.
27	>
28	>	6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
29	>	internal SQL tokeniser routines.
30	>
31	>	7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
32	>	being raised for valid set statements processed by a data formatter.
33	>
34	>	8. New published property for TIBDatabase and TIBXServicesConnection. This is
35	>	FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
36	>	the path of the Firebird Library used by the database/services connection.
37	>
38	>	9. New read only public property for TIBDatabase and TIBXServicesConnection. This
39	>	is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
40	>	services connection.
41	>
42	>	10.SQL Property editors now quote parameter names if "Quote identifier" is selected
43	>	or param name is not a valid SQL identifier.
44	>
45	>	11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
46	>	view of whether the text box should be editable when no DataSource is specified.
47	>	TIBLookupComboEditBox has been updated to workaround this problem. As long as
48	>	ReadOnly is false, the text box is editable when no DataSource is specified.
49	>
50	>	12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
51	>	the FBLIB environment variable. If you do not want to permit this then you
52	>	must modify the Register procedure in the design/IBDBReg.pas unit to remove
53	>	this setting.

62	>	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
63	>	all previous copies of the IBX source code tree before installing this release.
64	>
65	>	The IBX packages used by most users have not changed, with one exception. The
66	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
67	>	to use the IBServices unit in your applications, please add the iblegacyServices
68	>	to the list of dependencies. To do this, open the Project Inspector and select
69	>	Add->New Requirement and select "ibLegacyServices" from the list of available
70	>	packages.
71	>
72	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
73	>	the IBServices unit providing what is intended to be a clearer and easier to
74	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
75	>	more information and the guide to "Firebird Service Management Using IBX".
76	>	As indicated above, the legacy services components are still available and
77	>	provided in a separate package. There is no need to update working applications
78	>	using the older versions except for an additional package dependency.
79	>
80	>	2. The IBX packages and source code tree have been re-organised in an attempt to
81	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
82	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
83	>	new set of IBX packages.
84	>
85	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
86	>	updated to use the new Services API components.
87	>
88	>	4. The iblocal package has been updated to use the new Services API components.
89	>
90	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
91	>	TIBXSecurityService. It had been wrongly classified in the previous version
92	>	as a per database configuration item. It is global to a server and hence
93	>	correctly positioned as part of the Security Package. In the DBAdmin example,
94	>	the setting has moved to the mappings page.
95	>
96	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
97	>	are ignored.
98	>
99	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
100	>	closed before the database is dropped. Before and After Disconnect event handlers
101	>	are also fired.
102	>
103	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
104	>	is started and not just the first time.
105	>
106	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
107	>	depenendency with comp type.
108	>
109	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
110	>
111	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
112	>	then this is recognised and not ignored.
113	>
114	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
115	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
116	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
117	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
118	>
119	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
120	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
121	>	counters for the select query. Note: stats accumulate after each fetch from
122	>	the database. To get total query cost after open, call the "Last" method
123	>	and then GetPerfStatistics.
124	>
125	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
126	>
127	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
128	>	in parenthesises.
129	>
130	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
131	>	SQL identifiers are always delimited by double quotes. If false, then they are
132	>	only delimited if the identifier is a reserved word, contains lower case or special
133	>	characters. Set this property to true to retain previous behaviour.
134	>
135	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
136	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
137	>
138	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
139	>	property MasterDetailDelay: integer {defaults to zero}
140	>
141	>	When non-zero and the dataset is a detail table referencing a master table
142	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
143	>	then a synchronisation delay is added (in milliseconds) between the master
144	>	row changing and the detail dataset being re-opened. If the master dataset
145	>	is scrolled before the delay expires then the delay is reset. This can be used
146	>	to avoid performance overheads when scrolling through a large master dataset.
147	>
148	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
149	>	chreads unit must be included in your project. TTimer is not used in order
150	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
151	>
152	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
153	>	with Extract Option eoDatabase.
154	>
155	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
156	>	When a deLayoutChanged event is reported on the ListSource dataset, the
157	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
158	>	relationship with the control's datasource (master).
159	>
160	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
161	>
162	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
163	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
164	>
165	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
166	>	DDL (Firebird 3 and later only).
167	>
168	>	22. TIBLookupComboBox Autocomplete Fixes:
169	>	i. Only appended text is now selected after autocomplete.
170	>	ii. Uppercase keys no longer ignored for autocomplete.
171	>	iii. Retain Prefix case is now honoured correctly.
172	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
173	>	before autocomplete performed. i.e. behaviour now the same as when
174	>	no DataSource assigned.
175	>
176	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
177	>	between SQL statements.
178	>
179	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
180	>	ObjectNames are converted to upper case before matching against metadata object
181	>	names, unless the objectname is delimited by double quotes, in which case, the
182	>	double quotes are removed and the remaining string is used (unmodified) to match
183	>	against the metadata object name.
184	>
185	>	If true then the ObjectName is used as is without modification and matched
186	>	against the metadata object name. No attempt is made to remove double quotes.
187	>
188	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
189	>	with eoTrigger, these extract types can be used to select only Database Triggers,
190	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
191	>
192	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
193	>	statement separate character is now reset to the default (';').
194	>
195	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
196	>
197	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
198	>	a commit or reconnect statement and instead activated only when next SQL statement
199	>	is executed.
200	>
201	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
202	>
203	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
204	>	converting statement to upper case.
205	>
206	>	31. TIBExtract: metadata comments now supported. New published property
207	>	IncludeMetaDataComments (default true). If true then metadata comments included
208	>	in extracted DDL. New Extract Object member eoComments. This may be used with
209	>	ExtractObject method to list all metadata comments.
210	>
211	>	32. TIBExtract: ListObjectNames method added.
212	>
213	>	33. Updated Database component editor to support additional connection string
214	>	types.

239	>	returning should be significantly more efficient than executing a refresh query.
240
241		This behaviour change is intended to be backwards compatible and there should be no need to change
242		existing programs, other than to improve performance by using the new capability.

251	>	the deletion of a row with the returned values.
252	>
253	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
254		any Computed By or Identity Columns. The IBTables example has been updated to
255		illustrate the computation of the employee Full Name on update.
256
257	<	4. TIBTable: The GeneratorField property is now published.

259	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
260		When InsertSQL is generated, the Identity columns are not included in the list of values to
261		be inserted. A RETURNING clause is added to the insert statement to return the value of
262		each Identity column after the insert is executed.
263
264	<	6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.

277		values are no longer converted to milliseconds from TDateTime and then back again
278		to TDateTime (the conversion to milliseconds is the default TDataset approach).

280	<	11. Property Editors handling of Stored Procedures.
280	>	12. Property Editors handling of Stored Procedures.
281		* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
282		which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
283		query).
284		* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
285
286	<	12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
286	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
287		can be used to select a package. If non-empty, the stored procedure name is
288		expected to be a stored procedure defined in the specified package and the
289		generated SQL will be as required for a stored procedure located in a package.
290
291	<	13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
291	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
292		a "Package Name" drop down box to allow selection of a Firebird 3 Package from

298
299	+	16. TIBDatabase: use IAttachment for connection default character set id, code page
300	+	and character set name.
301	+
302	+	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
303	+	DB info lookups"
304	+
305	+	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
306	+
307	+	19. Add a property Editor for TIBUpdate.RefreshSQL.
308	+
309	+	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
310	+	parameters. This stops an exception being raised when the field cannot be
311	+	located in the record buffer.
312	+
313	+	21. Property Editors now automatically include System Tables when opened and when the query table
314	+	is a System Table.
315	+
316	+	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
317	+	This avoids errors due to a stale SQRB or SRB being used for the next query.
318	+
319	+	23. IBServices: Service attach parameters now include "expected_db". This is used to
320	+	add the SPB item isc_spb_expected_db. This names a database using
321	+	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
322	+	database. examples/services re-written to illustrate use of "expected_db".
323	+
324	+	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
325	+	This avoids truncated backups when the server returns a timeout (busy) response.
326	+
327	+	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
328	+
329	+	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
330	+	databasenames. These are respectively expanded to the local system's temp directory
331	+	(including trailing delimiter) or to a prescribed data directory (including
332	+	trailing delimiter). Under Unix systems the data directory is a hidden directory
333	+	in the user's home directory. The hidden directory name is either the string returned
334	+	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
335	+	Under Windows, the directory is the same as the Data Directory as decribed
336	+	above but instead prefixed by the User's application data path. These may be
337	+	used to improve application portability for Personal Databases.
338	+
339	+	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
340	+	this has not worked for a long time and is not useful either. FieldDefs should be
341	+	managed using the Fields Editor as with any other dataset. To access the fields
342	+	editor for a TIBTable component, double click on the component. The fields editor
343	+	is then displayed.
344	+
345	+	28. TIBDatabaseInfo: new properties/function
346	+	* DateDBCreated (returns date/time database created)
347	+	* TransactionCount (returns no. of active transactions)
348	+	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
349	+	* PagesFree (Firebird 3 or later)
350	+	* PagesUsed (Firebird 3 or later)
351	+	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
352	+	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
353	+
354	+	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
355	+
356	+	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
357	+
358	+	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
359	+	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
360	+
361	+	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
362	+	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
363	+	firing during backup and restore.
364	+
365	+	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
366	+	for verbose output using the new property "StatisticsRequested".
367	+	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
368	+
369	+	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
370	+
371	+	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
372	+	palette. This uses the online validation feature added in Firebird 2.5. The
373	+	services's properties enable inclusion/exclusion of tables and indexes using
374	+	regular expressions. See.
375	+	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
376	+
377	+	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
378	+	option on a database.
379	+
380	+	37. TIBCustomService: Assign method implemented to allow copying of service login
381	+	context between service API components. "Detach" method now only detaches
382	+	service when last reference to the service interface detaches. Tidy up of
383	+	code for SetActive and Attach methods including password hiding.
384	+
385	+	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
386	+	and used to determine the auth method and protocol used for the connection.
387	+
388	+	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
389	+	a Create Database Statement generated by IBX.
390	+
