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	>

137	>
138	>	NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
139	>	AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
140	>	RELEASE.

156		a returning clause that updates one or more fields on the current row. A full row
157		refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
158		field values and the select query contains read only fields. Use of Insert/update
159	<	returning should be significantly more efficient than excuting a refresh query.
159	>	returning should be significantly more efficient than executing a refresh query.
160
161		This behaviour change is intended to be backwards compatible and there should be no need to change
162		existing programs, other than to improve performance by using the new capability.

165	>	they are called when the dataset row is being deleted, there is no value in
166	>	updating the current record from the query result. Instead, a new event handler
167	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
168	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
169	>	by the query. The event handler can then interrogate the query results and
170	>	perform whatever action is necessary. For example to confirm, to the user,
171	>	the deletion of a row with the returned values.
172	>
173	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
174		any Computed By or Identity Columns. The IBTables example has been updated to
175		illustrate the computation of the employee Full Name on update.
176
177	<	4. TIBTable: The GeneratorField property is now published.
177	>	5. TIBTable: The GeneratorField property is now published.
178
179	<	5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
179	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
180		When InsertSQL is generated, the Identity columns are not included in the list of values to
181		be inserted. A RETURNING clause is added to the insert statement to return the value of
182		each Identity column after the insert is executed.
183
184	<	6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
184	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
185		Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
186		Insert..Returning clause.
187

196	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
197		values are no longer converted to milliseconds from TDateTime and then back again
198		to TDateTime (the conversion to milliseconds is the default TDataset approach).
199
200	<	11. Property Editors handling of Stored Procedures.
200	>	12. Property Editors handling of Stored Procedures.
201		* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
202		which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
203		query).
204		* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
205
206	<	12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
206	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
207		can be used to select a package. If non-empty, the stored procedure name is
208		expected to be a stored procedure defined in the specified package and the
209		generated SQL will be as required for a stored procedure located in a package.
210
211	<	13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
211	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
212		a "Package Name" drop down box to allow selection of a Firebird 3 Package from
213		which a stored procedure can be selected. With no package name selected, non-package
214		stored procedures are listed.

216	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
217		for password on reconnect.
218
219	+	16. TIBDatabase: use IAttachment for connection default character set id, code page
220	+	and character set name.
221	+
222	+	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
223	+	DB info lookups"
224	+
225	+	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
226	+
227	+	19. Add a property Editor for TIBUpdate.RefreshSQL.
228	+
229	+	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
230	+	parameters. This stops an exception being raised when the field cannot be
231	+	located in the record buffer.
232	+
233	+	21. Property Editors now automatically include System Tables when opened and when the query table
234	+	is a System Table.
235	+
236	+	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
237	+	This avoids errors due to a stale SQRB or SRB being used for the next query.
238	+
239	+	23. IBServices: Service attach parameters now include "expected_db". This is used to
240	+	add the SPB item isc_spb_expected_db. This names a database using
241	+	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
242	+	database. examples/services re-written to illustrate use of "expected_db".
243	+
244	+	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
245	+	This avoids truncated backups when the server returns a timeout (busy) response.
246	+
247	+	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
248	+
249	+	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
250	+	databasenames. These are respectively expanded to the local system's temp directory
251	+	(including trailing delimiter) or to a prescribed data directory (including
252	+	trailing delimiter). Under Unix systems the data directory is a hidden directory
253	+	in the user's home directory. The hidden directory name is either the string returned
254	+	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
255	+	Under Windows, the directory is the same as the Data Directory as decribed
256	+	above but instead prefixed by the User's application data path. These may be
257	+	used to improve application portability for Personal Databases.
258	+
259	+	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
260	+	this has not worked for a long time and is not useful either. FieldDefs should be
261	+	managed using the Fields Editor as with any other dataset. To access the fields
262	+	editor for a TIBTable component, double click on the component. The fields editor
263	+	is then displayed.
264	+
265	+	28. TIBDatabaseInfo: new properties/function
266	+	* DateDBCreated (returns date/time database created)
267	+	* TransactionCount (returns no. of active transactions)
268	+	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
269	+	* PagesFree (Firebird 3 or later)
270	+	* PagesUsed (Firebird 3 or later)
271	+	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
272	+	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
273	+
274	+	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
275	+
276	+	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
277	+
278	+	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
279	+	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
280	+
281	+	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
282	+	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
283	+	firing during backup and restore.
284	+
285	+	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
286	+	for verbose output using the new property "StatisticsRequested".
287	+	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
288	+
289	+	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
290	+
291	+	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
292	+	palette. This uses the online validation feature added in Firebird 2.5. The
293	+	services's properties enable inclusion/exclusion of tables and indexes using
294	+	regular expressions. See.
295	+	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
296	+
297	+	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
298	+	option on a database.
299	+
300	+	37. TIBCustomService: Assign method implemented to allow copying of service login
301	+	context between service API components. "Detach" method now only detaches
302	+	service when last reference to the service interface detaches. Tidy up of
303	+	code for SetActive and Attach methods including password hiding.
304	+
305	+	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
306	+	and used to determine the auth method and protocol used for the connection.
307	+
308	+	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
309	+	a Create Database Statement generated by IBX.
310	+
311	+	40. All IBServices now have an additional published property "PortNo". This may
312	+	be set to a non-standard port number when necessary. If zero then the default
313	+	port number is used.
314	+
315	+	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
316	+	and not just the mouse.
317	+
318	+	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
319	+
320	+	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
321	+	image index and selected image index for each node to be set from a database field.
322	+
323	+	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
324	+	then database schema includes grants to all users. If not present then the
325	+	only user grants included are those to User PUBLIC.
326	+
327	+	45. TIBTreeView: performance improvement. When expanding include both expanded node
328	+	and child nodes in dataset.
