3	>	IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4	>	all previous copies of the IBX source code tree before installing this release.
5	>
6	>	The IBX packages used by most users have not changed, with one exception. The
7	>	IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8	>	to use the IBServices unit in your applications, please add the iblegacyServices
9	>	to the list of dependencies. To do this, open the Project Inspector and select
10	>	Add->New Requirement and select "ibLegacyServices" from the list of available
11	>	packages.
12	>
13	>	1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14	>	the IBServices unit providing what is intended to be a clearer and easier to
15	>	use set of IB Services components. See Chapter 10 of the IBX User Guide for
16	>	more information and the guide to "Firebird Service Management Using IBX".
17	>	As indicated above, the legacy services components are still available and
18	>	provided in a separate package. There is no need to update working applications
19	>	using the older versions except for an additional package dependency.
20	>
21	>	2. The IBX packages and source code tree have been re-organised in an attempt to
22	>	finally get rid of the "duplicate ppu" warnings. This re-organisation should
23	>	not affect existing users. Section 2.3 of the IBX User Guide describes the
24	>	new set of IBX packages.
25	>
26	>	3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27	>	updated to use the new Services API components.
28	>
29	>	4. The iblocal package has been updated to use the new Services API components.
30	>
31	>	5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32	>	TIBXSecurityService. It had been wrongly classified in the previous version
33	>	as a per database configuration item. It is global to a server and hence
34	>	correctly positioned as part of the Security Package. In the DBAdmin example,
35	>	the setting has moved to the mappings page.
36	>
37	>	6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38	>	are ignored.
39	>
40	>	7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41	>	closed before the database is dropped. Before and After Disconnect event handlers
42	>	are also fired.
43	>
44	>	8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45	>	is started and not just the first time.
46	>
47	>	9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48	>	depenendency with comp type.
49	>
50	>	10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51	>
52	>	11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53	>	then this is recognised and not ignored.
54	>
55	>	12. TIBDataSet, TIBQuery, TIBTable: additions:
56	>	function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57	>	function GetPerfStatistics(var stats: TPerfCounters): boolean;
58	>	property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59	>
60	>	GetRowsAffected returns the affected row counts from the last insert/update/delete
61	>	if EnableStatistics = true then GetPerfStatistics returns the current stats
62	>	counters for the select query. Note: stats accumulate after each fetch from
63	>	the database. To get total query cost after open, call the "Last" method
64	>	and then GetPerfStatistics.
65	>
66	>	See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67	>
68	>	13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69	>	in parenthesises.
70	>
71	>	14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72	>	SQL identifiers are always delimited by double quotes. If false, then they are
73	>	only delimited if the identifier is a reserved word, contains lower case or special
74	>	characters. Set this property to true to retain previous behaviour.
75	>
76	>	15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77	>	are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78	>
79	>	16. TIBDataSet, TIBQuery, TIBTable: addition:
80	>	property MasterDetailDelay: integer {defaults to zero}
81	>
82	>	When non-zero and the dataset is a detail table referencing a master table
83	>	through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84	>	then a synchronisation delay is added (in milliseconds) between the master
85	>	row changing and the detail dataset being re-opened. If the master dataset
86	>	is scrolled before the delay expires then the delay is reset. This can be used
87	>	to avoid performance overheads when scrolling through a large master dataset.
88	>
89	>	Note: uses fptimer and hence requires a thread manager. Under Linux the
90	>	chreads unit must be included in your project. TTimer is not used in order
91	>	to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92	>
93	>	17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94	>	with Extract Option eoDatabase.
95	>
96	>	18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97	>	When a deLayoutChanged event is reported on the ListSource dataset, the
98	>	combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99	>	relationship with the control's datasource (master).
100	>
101	>	19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102	>
103	>	20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104	>	stubs. Pedantic fix really, as procedures output in dependency order anyway.
105	>
106	>	21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107	>	DDL (Firebird 3 and later only).
108	>
109	>	22. TIBLookupComboBox Autocomplete Fixes:
110	>	i. Only appended text is now selected after autocomplete.
111	>	ii. Uppercase keys no longer ignored for autocomplete.
112	>	iii. Retain Prefix case is now honoured correctly.
113	>	iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114	>	before autocomplete performed. i.e. behaviour now the same as when
115	>	no DataSource assigned.
116	>
117	>	23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118	>	between SQL statements.
119	>
120	>	24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121	>	ObjectNames are converted to upper case before matching against metadata object
122	>	names, unless the objectname is delimited by double quotes, in which case, the
123	>	double quotes are removed and the remaining string is used (unmodified) to match
124	>	against the metadata object name.
125	>
126	>	If true then the ObjectName is used as is without modification and matched
127	>	against the metadata object name. No attempt is made to remove double quotes.
128	>
129	>	25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130	>	with eoTrigger, these extract types can be used to select only Database Triggers,
131	>	or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
132	>
133	>	26. TIBXScript: If an exception occurs during the processing of a statement, the
134	>	statement separate character is now reset to the default (';').
135	>
136	>	27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
137	>
138	>	28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
139	>	a commit or reconnect statement and instead activated only when next SQL statement
140	>	is executed.
141	>
142	>	29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
143	>
144	>	30. TIBXScript: case insensitive regex now used when matching statements instead of
145	>	converting statement to upper case.
146	>
147	>	31. TIBExtract: metadata comments now supported. New published property
148	>	IncludeMetaDataComments (default true). If true then metadata comments included
149	>	in extracted DDL. New Extract Object member eoComments. This may be used with
150	>	ExtractObject method to list all metadata comments.
151	>
152	>	32. TIBExtract: ListObjectNames method added.
153	>
154	>	33. Updated Database component editor to support additional connection string
155	>	types.
156	>
157	>	IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
158	>
159	>	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
160	>	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
161	>	RELEASE.
162	>
163	>	NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
164	>
165	>	1. IBExtract: Identity columns - add additional check for null column for generator name.
166	>
167	>	2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
168	>	The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
169	>	information). However, this is also a very useful mechanism for returning updated computed by
170	>	column values. Values returned as a result of executing an Insert or Update statement
171	>	replace existing values in the current row for each corresponding column.
172	>
173	>	Previously, if a dataset's select query included read only (computed by) fields then
174	>	an automatic row refresh was performed after an insert or update query had been processed,
175	>	irrespective of the setting of the "ForcedUpdates" property. This has changed such
176	>	that an automatic refresh is no longer performed if an insert or update query contains
177	>	a returning clause that updates one or more fields on the current row. A full row
178	>	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
179	>	field values and the select query contains read only fields. Use of Insert/update
180	>	returning should be significantly more efficient than executing a refresh query.
181	>
182	>	This behaviour change is intended to be backwards compatible and there should be no need to change
183	>	existing programs, other than to improve performance by using the new capability.
184	>
185	>	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
186	>	they are called when the dataset row is being deleted, there is no value in
187	>	updating the current record from the query result. Instead, a new event handler
188	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
189	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
190	>	by the query. The event handler can then interrogate the query results and
191	>	perform whatever action is necessary. For example to confirm, to the user,
192	>	the deletion of a row with the returned values.
193	>
194	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
195	>	any Computed By or Identity Columns. The IBTables example has been updated to
196	>	illustrate the computation of the employee Full Name on update.
197	>
198	>	5. TIBTable: The GeneratorField property is now published.
199	>
200	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
201	>	When InsertSQL is generated, the Identity columns are not included in the list of values to
202	>	be inserted. A RETURNING clause is added to the insert statement to return the value of
203	>	each Identity column after the insert is executed.
204	>
205	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
206	>	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
207	>	Insert..Returning clause.
208	>
209	>	8. TIBGenerator: small performance improvement by not preparing query each time
210	>	a new value is generated.
211	>
212	>	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
213	>
214	>	10. Property editors will now sync table name to a System Table when "Include System
215	>	Tables" is selected and the query is for a System Table.
216	>
217	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
218	>	values are no longer converted to milliseconds from TDateTime and then back again
219	>	to TDateTime (the conversion to milliseconds is the default TDataset approach).
220	>
221	>	12. Property Editors handling of Stored Procedures.
222	>	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
223	>	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
224	>	query).
225	>	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
226	>
227	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
228	>	can be used to select a package. If non-empty, the stored procedure name is
229	>	expected to be a stored procedure defined in the specified package and the
230	>	generated SQL will be as required for a stored procedure located in a package.
231	>
232	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
233	>	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
234	>	which a stored procedure can be selected. With no package name selected, non-package
235	>	stored procedures are listed.
236	>
237	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
238	>	for password on reconnect.
239	>
240	>	16. TIBDatabase: use IAttachment for connection default character set id, code page
241	>	and character set name.
242	>
243	>	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
244	>	DB info lookups"
245	>
246	>	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
247	>
248	>	19. Add a property Editor for TIBUpdate.RefreshSQL.
249	>
250	>	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
251	>	parameters. This stops an exception being raised when the field cannot be
252	>	located in the record buffer.
253	>
254	>	21. Property Editors now automatically include System Tables when opened and when the query table
255	>	is a System Table.
256	>
257	>	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
258	>	This avoids errors due to a stale SQRB or SRB being used for the next query.
259	>
260	>	23. IBServices: Service attach parameters now include "expected_db". This is used to
261	>	add the SPB item isc_spb_expected_db. This names a database using
262	>	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
263	>	database. examples/services re-written to illustrate use of "expected_db".
264	>
265	>	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
266	>	This avoids truncated backups when the server returns a timeout (busy) response.
267	>
268	>	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
269	>
270	>	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
271	>	databasenames. These are respectively expanded to the local system's temp directory
272	>	(including trailing delimiter) or to a prescribed data directory (including
273	>	trailing delimiter). Under Unix systems the data directory is a hidden directory
274	>	in the user's home directory. The hidden directory name is either the string returned
275	>	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
276	>	Under Windows, the directory is the same as the Data Directory as decribed
277	>	above but instead prefixed by the User's application data path. These may be
278	>	used to improve application portability for Personal Databases.
279	>
280	>	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
281	>	this has not worked for a long time and is not useful either. FieldDefs should be
282	>	managed using the Fields Editor as with any other dataset. To access the fields
283	>	editor for a TIBTable component, double click on the component. The fields editor
284	>	is then displayed.
285	>
286	>	28. TIBDatabaseInfo: new properties/function
287	>	* DateDBCreated (returns date/time database created)
288	>	* TransactionCount (returns no. of active transactions)
289	>	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
290	>	* PagesFree (Firebird 3 or later)
291	>	* PagesUsed (Firebird 3 or later)
292	>	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
293	>	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
294	>
295	>	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
296	>
297	>	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
298	>
299	>	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
300	>	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
301	>
302	>	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
303	>	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
304	>	firing during backup and restore.
305	>
306	>	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
307	>	for verbose output using the new property "StatisticsRequested".
308	>	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
309	>
310	>	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
311	>
312	>	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
313	>	palette. This uses the online validation feature added in Firebird 2.5. The
314	>	services's properties enable inclusion/exclusion of tables and indexes using
315	>	regular expressions. See.
316	>	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
317	>
318	>	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
319	>	option on a database.
320	>
321	>	37. TIBCustomService: Assign method implemented to allow copying of service login
322	>	context between service API components. "Detach" method now only detaches
323	>	service when last reference to the service interface detaches. Tidy up of
324	>	code for SetActive and Attach methods including password hiding.
325	>
326	>	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
327	>	and used to determine the auth method and protocol used for the connection.
328	>
329	>	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
330	>	a Create Database Statement generated by IBX.
331	>
332	>	40. All IBServices now have an additional published property "PortNo". This may
333	>	be set to a non-standard port number when necessary. If zero then the default
334	>	port number is used.
335	>
336	>	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
337	>	and not just the mouse.
338	>
339	>	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
340	>
341	>	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
342	>	image index and selected image index for each node to be set from a database field.
343	>
344	>	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
345	>	then database schema includes grants to all users. If not present then the
346	>	only user grants included are those to User PUBLIC.
347	>
348	>	45. TIBTreeView: performance improvement. When expanding include both expanded node
349	>	and child nodes in dataset.
350	>
351	>
352	>	IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
353	>
354	>	1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
355	>	changes.
356	>
357	>	2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
358	>	Bug could result in truncated multi-byte character set values.
359	>
360	>	3. Changes consequential on moving fbintf character set utility functions from
361	>	IFirebirdAPI to IAttachment.
362	>
363	>	4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
364	>
365	>	5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
366	>	results in autocomplete ignoring prefix text.
367	>
368	>	6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
369	>	entering a new name into the text box.
370	>
371	>	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
372	>	Firebird rather than recomputing it.
373	>
374	>	8. Property Editor positioning tidy up: All IBX Property editors should now be
375	>	screen centre. Previously some were "poDesigned" which may be inappropriate
376	>	for multi monitor desktops.
377	>
378	>	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
379	>
380	>	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
381	>	a transaction and always reset the object.
382	>
383	>	12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
384	>
385	>	13. TIBXScript: Allow for override of database filename in Create Database statements.
386	>
387	>	14. IBLocaldb: Support initialisation of the database from an SQL script in addition
388	>	to a gbak format archive.
389	>
390	>	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
391	>
392	>	16. IBLocaldb: Drop database if error creating an empty database.
393	>
394	>	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
395	>	unless selected node not in current dataset.
396	>
397	>	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
398	>	to TIBCustomService, and IBlocalDB code tidy up.
399	>
400	>	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
401	>	behaviour due to uninitialised variable.

502	>	1. Size property of TIBStringField is now the width in characters of the field
503	>	and not the byte length. This applies only to multi-byte character sets such
504	>	as UTF8. The original approach aligned with TStringField. However, the TStringField
505	>	code is not recognised as a bug and hence this change to align the behaviour.
506	>	The TStringField change is expected in fpc 3.2.0.
507	>
508	>	2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
509	>	true (default) then Size property value saved in the lfm is ignored. Size is
510	>	always set from the dynamic information read from the database. It is unclear
511	>	why anyone would want to override this and set Size to false.
512	>
513	>	3. ibxscript: should now handle correctly a Case..End statement within a procedure
514	>	block.
515	>
516	>	4. IBDatabase: new property - CreateIfNotExists. If true and database does not
517	>	exist when an attempt is made to connect to it (run time only) then an attempt
518	>	is made to create the database.
519	>
520	>	5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
521	>	has been successfully created as a result of a call to CreateDatabase or when
522	>	creating a database after it was found not to exist.
523	>
524	>	6.  DBControlGrid: a race condition could result in the wrong row image being
525	>	written to the cache. This has been avoided by a trip round the message
526	>	loop before rendering the row image.
527	>
528	>	7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
529	>	a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
530	>	known to risk corrupt rendering of row images when the control is first

532	>	of the dataset (see DBControlGrid examples) until the Form's Window has been created.

588	>	1. No character set specified for connection: when a text blob is retrieved, the

593	>	2. TIBGUIInterface: this is an internal interface. Minor type changes to allow

598	>	entered value to be saved on a project specific basis (design time only).
599	>
600	>	4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the

602	>	Otherwise, it sets the column text to the selected ListField Value.

756	>	See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a

758	>	application is GUI based. Instead, you should include the ibexpressconsolemode package.
759	>
760	>	IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
761	>	to use the built in dialogs and cursor management. IBDialogs is
762	>	included by default if "ibexpress" is in your project source's "uses" clause.
763	>	This should be the case for all projects created through the IDE. This is why
764	>	you do not want to add the ibexpress package to console mode applications. The

771	>
772	>	You may find that in order for the IDE to recognise that ibexpressconsolemode
773	>	exists, you have to first open the package in the IDE and then close it. This

786	>
787	>	10. Fix error when writing to blob streams that recorded only the last buffer
788	>	write in the blob stream. In most cases, this did not cause a problem as the
789	>	IB Blob Stream is written in a single write. However, with the TDBImage, write

792	>
793	>	11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
794	>	already open" errors due to random numbers used for the cursor name being identical.

806	>	1.  Firebird Services: avoid List Index error when opening a service with an
807	>	empty Params property.
808	>
809	>	2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
810	>	Link now set up in Loaded method - avoids occasional failure to apply
811	>	SQL markup on initial open.
812	>
813	>	3.  "Employees" example performance improvements when scrolling.
814	>
815	>	4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
816	>	TFrame. Force recaching of selected frame to avoid GTK race (results in a
817	>	random image cached).
818	>
819	>	5.  DBControlGrid: Should now react to changes in panel height at run time.
820	>
821	>	6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
822	>	even when further rows exist.
823	>
824	>	7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
825	>	always be derived from panel height and setting this property can cause confusion.
826	>	Note for existing projects: to avoid a missing property error at run time,
827	>	each form using the DBControlGrid must be opened, updated and saved in the IDE
828	>	in order to remove the property value from the lfm.

832	>
833	>	1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
834	>	call Prepare before setting parameter values.
835	>
836	>	2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
837	>
838	>	3.  Code tidyup and more robust handling of dsql information result vector.
839	>
840	>	4.  Support for centralised handling of transaction status changes. TIBTransaction
841	>	has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
842	>	and "AfterExecQuery". The first three are called after the same event is called
843	>	for an IBCustomDataSet descendent using the Transaction. The fourth is called
844	>	after a call to TIBSQL.ExecQuery, again using this transaction. These new events
845	>	enable monitoring of transaction status changes for a given transaction to be
846	>	handled in a single place. For example, when a change to the dataset occurs
847	>	an indicator can be set that shows the user that in order to save changes,
848	>	the transaction should be committed.  Rather than doing this per dataset, this
849	>	can now be done per transaction.
850	>
851	>	5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
852	>	the dataset is scrolled. However, any changes to the current row are, by default,
853	>	discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
854	>	have a new property "DataSetCloseAction" that adds automatic posting of changes
855	>	on dataset close. If this property is set to dcDiscardChanges (default) then the
856	>	behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
857	>	then IBX will attempt to post any unsaved changes before the dataset is closed
858	>	(and after the BeforeClose event handler is called). The exception is when the
859	>	dataset is being closed as a result of a transaction rollback. In this case,
860	>	no action is taken and any unsaved  changes are discarded. This avoids both
861	>	unnecessary overhead and the risk that a validation error may occur in the Post
862	>	raising an exception and thereby preventing a rollback.
863	>
864	>	6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
865	>	In earlier versions, the Display Width was set to the maximum byte width rather than the character
866	>	width. Display Widths are now corrected by dividing by the max byte width per character.
867	>	For UTF8 character sets, the byte width is four and hence the Display Width will be
868	>	the byte width divided by 4. The byte width of each character set is determined
869	>	dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
870	>	system table. (see also http://bugs.freepascal.org/view.php?id=27766).
871	>
872	>	7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
873	>
874	>	8.  IBLookupComboEditBox: List should now always be restored to full list when the
875	>	control loses focus. Default Key press default interval reduced to 200ms.
876	>
877	>	9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
878	>	when dataset rows are less than visible rows.
879	>
880	>	10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
881	>	does not exist or DataSet is empty. More responsive on dataset open. New event
882	>	OnRestorePosition. Column sort disabled if no header row.
883	>
884	>	11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
885	>	while dataset state is dsInsert. Avoids posting errors.
886	>
887	>	12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
888	>	avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
889	>
890	>	13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
891	>
892	>	14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
893	>	to solve a specific problem. That is when the dataset cursor is moved (e.g. by
894	>	a grid mouse click and the current row is being edited or inserted. In this case, TDataset
895	>	always "posts" the current record regardless or whether or not it may be more appropriate
896	>	to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
897	>	"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
898	>	as the first action of the "Post" method and allows the handler to convert the Post
899	>	into a Cancel if that is the appropriate action on moving to a different row. This is
900	>	achieved by returning with "CancelPost" argument set to true. Note that an exception could be
901	>	raised here, but it may still be more appropriate to validate a post and signal
902	>	a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
903	>
904	>	15. On Unix derived systems, the Firebird library name can now be given as a colon
905	>	separated list. Each library name on the list is tried in turn, in left to right
906	>	order with the first found being used as the firebird library. By default, on Linux,
907	>	the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
908	>	overidden by the FBLIB environment variable or the OnGetLibraryName function.
909	>
910	>	Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
911	>	then it will still attempt to access the database via the Firebird Server and will
912	>	require a username and password. If only the pathname is given, then the username
913	>	and password should be omitted and the unix file permissions are used to grant
914	>	access.

917	>
918	>	1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
919	>	rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
920	>	that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
921	>	corresponds to a row of the linked DataSource. Any data aware control on the
922	>	replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
923	>
924	>	2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
925	>	When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
926	>	takes place during database access. This may be useful when there are performance issues with
927	>	the change of cursor. Setting the property to false suppresses the change of cursor.
928	>
929	>	3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
930	>	and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
931	>	Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
932	>	making all changes permanent immediately rather than when the transaction is explicitly
933	>	committed.
934	>
935	>	4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
936	>	using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

943	>
944	>	1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
945	>	This is typically used during an "OnBeforeOpen" event handler to manipulate the
946	>	"Where" and "Having" clauses to implement user specified filters of arbitrary
947	>	complexity.
948	>
949	>	2. A new Component Palette entry "Firebird Data Controls" is now available. This has
950	>	three new data aware controls dependent on IBX and which make use of the SQL Parser.
951	>	These are:
952	>
953	>	- TIBLookupComboEditBox
954	>	- TIBDynamicGrid
955	>	- TIBTreeview
956	>
957	>	TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
958	>	of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
959	>	to revise the available list and restrict it to items that are prefixed by the
960	>	typed text (either case sensitive or case insensitive). Autoinsert allows a
961	>	newly typed entry to be added to the list dataset and included in the available
962	>	list items.
963	>
964	>	TIBDynamicGrid is a TDBGrid descendent that provides for:
965	>	- automatic resizing of selected columns to fill the available row length
966	>	- automatic positioning and sizing of a "totals" control, typically at the
967	>	column footer, on a per column basis.
968	>	- DataSet resorting on header row click, sorting the dataset by the selected column.
969	>	A second click on the same header cell reversed the sort order.
970	>	- Support for a "Panel Editor". That is on clicking the indicator column, the row
971	>	is automatically expanded and a panel superimposed on it. The panel can have any
972	>	number of child controls, typically data aware controls with the same datasource
973	>	as the grid allowing for editing of additional fields and more complex editors.
974	>	- Reselection of the same row following resorting.
975	>	- A new cell editor that provides the same functionality as TIBLookupComboEditBox.
976	>	Its properties are specified on a per column basis and allows for one or more
977	>	columns to have their values selected from a list provided by a dataset.
978	>	Autocomplete and autoinsert are also available. The existing picklist editor
979	>	is unaffected by the extension.
980	>
981	>	TIBTreeView is a data aware TCustomTreeView.
982	>
983	>	3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
984	>	zero scale will no longer return an error. An Int64 will be returned instead.
985	>
986	>	4. TIBTransaction now has events for Before and After Transaction End and a new function
987	>	"GetEndAction" allowing the EndAction to be accessed by these event handlers.
988	>
989	>	5. TIBQuery can now handle correctly queries which contain the same keyword parameter
990	>	repeated multiple times.
991	>
992	>	6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
993	>	check used to get in the way of using Stored Procedures, and "Update or Insert"
994	>	statements.
995	>
996	>	7. Insert, Modify and Delete property Editors now support Query Generation from
997	>	Stored Procedures.
998	>
999	>	8. Three new examples illustrate the use of the new IB Controls
1000	>
