9	>	1. IBExtract: Identity columns - add additional check for null column for generator name.
10
11		2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
12		The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
13	<	information). Values returned as a result of executing an Insert or Update statement
14	<	replace existing values in the current row for each corresponding column.
13	>	information). However, this is also a very useful mechanism for returning updated computed by
14	>	column values. Values returned as a result of executing an Insert or Update statement
15	>	replace existing values in the current row for each corresponding column.
16	>
17	>	Previously, if a dataset's select query included read only (computed by) fields then
18	>	an automatic row refresh was performed after an insert or update query had been processed,
19	>	irrespective of the setting of the "ForcedUpdates" property. This has changed such
20	>	that an automatic refresh is no longer performed if an insert or update query contains
21	>	a returning clause that updates one or more fields on the current row. A full row
22	>	refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
23	>	field values and the select query contains read only fields. Use of Insert/update
24	>	returning should be significantly more efficient than executing a refresh query.
25	>
26	>	This behaviour change is intended to be backwards compatible and there should be no need to change
27	>	existing programs, other than to improve performance by using the new capability.
28	>
29	>	3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
30	>	they are called when the dataset row is being deleted, there is no value in
31	>	updating the current record from the query result. Instead, a new event handler
32	>	"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
33	>	an OnDeleteReturning event handler is provided then it is called with the IResults returned
34	>	by the query. The event handler can then interrogate the query results and
35	>	perform whatever action is necessary. For example to confirm, to the user,
36	>	the deletion of a row with the returned values.
37	>
38	>	4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
39	>	any Computed By or Identity Columns. The IBTables example has been updated to
40	>	illustrate the computation of the employee Full Name on update.
41	>
42	>	5. TIBTable: The GeneratorField property is now published.
43
44	<	3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
44	>	6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
45		When InsertSQL is generated, the Identity columns are not included in the list of values to
46		be inserted. A RETURNING clause is added to the insert statement to return the value of
47		each Identity column after the insert is executed.
48
49	<	4. TIBGenerator: small performance improvement by not preparing query each time
50	<	a new number is generated.
49	>	7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
50	>	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
51	>	Insert..Returning clause.
52
53	<	5. TIBSQL: Free resources when transaction changed.
53	>	8. TIBGenerator: small performance improvement by not preparing query each time
54	>	a new value is generated.
55
56	<	6. Property editor will now sync table name to a System Table when "Include System
21	<	Tables" is selected and the query is for a System Table.
56	>	9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
57
58	<	7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
59	<	Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
60	<	Insert..Returning clause.
58	>	10. Property editors will now sync table name to a System Table when "Include System
59	>	Tables" is selected and the query is for a System Table.
60	>
61	>	11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
62	>	values are no longer converted to milliseconds from TDateTime and then back again
63	>	to TDateTime (the conversion to milliseconds is the default TDataset approach).
64	>
65	>	12. Property Editors handling of Stored Procedures.
66	>	* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
67	>	which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
68	>	query).
69	>	* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
70	>
71	>	13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
72	>	can be used to select a package. If non-empty, the stored procedure name is
73	>	expected to be a stored procedure defined in the specified package and the
74	>	generated SQL will be as required for a stored procedure located in a package.
75	>
76	>	14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
77	>	a "Package Name" drop down box to allow selection of a Firebird 3 Package from
78	>	which a stored procedure can be selected. With no package name selected, non-package
79	>	stored procedures are listed.
80	>
81	>	15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
82	>	for password on reconnect.
83	>
84	>	16. TIBDatabase: use IAttachment for connection default character set id, code page
85	>	and character set name.
86	>
87	>	17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
88	>	DB info lookups"
89	>
90	>	18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
91	>
92	>	19. Add a property Editor for TIBUpdate.RefreshSQL.
93	>
94	>	20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
95	>	parameters. This stops an exception being raised when the field cannot be
96	>	located in the record buffer.
97	>
98	>	21. Property Editors now automatically include System Tables when opened and when the query table
99	>	is a System Table.
100	>
101	>	22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
102	>	This avoids errors due to a stale SQRB or SRB being used for the next query.
103	>
104	>	23. IBServices: Service attach parameters now include "expected_db". This is used to
105	>	add the SPB item isc_spb_expected_db. This names a database using
106	>	an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
107	>	database. examples/services re-written to illustrate use of "expected_db".
108	>
109	>	24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
110	>	This avoids truncated backups when the server returns a timeout (busy) response.
111	>
112	>	25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
113	>
114	>	26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
115	>	databasenames. These are respectively expanded to the local system's temp directory
116	>	(including trailing delimiter) or to a prescribed data directory (including
117	>	trailing delimiter). Under Unix systems the data directory is a hidden directory
118	>	in the user's home directory. The hidden directory name is either the string returned
119	>	from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
120	>	Under Windows, the directory is the same as the Data Directory as decribed
121	>	above but instead prefixed by the User's application data path. These may be
122	>	used to improve application portability for Personal Databases.
123	>
124	>	27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
125	>	this has not worked for a long time and is not useful either. FieldDefs should be
126	>	managed using the Fields Editor as with any other dataset. To access the fields
127	>	editor for a TIBTable component, double click on the component. The fields editor
128	>	is then displayed.
129	>
130	>	28. TIBDatabaseInfo: new properties/function
131	>	* DateDBCreated (returns date/time database created)
132	>	* TransactionCount (returns no. of active transactions)
133	>	* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
134	>	* PagesFree (Firebird 3 or later)
135	>	* PagesUsed (Firebird 3 or later)
136	>	* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
137	>	* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
138	>
139	>	29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
140	>
141	>	30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
142	>
143	>	31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
144	>	the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
145	>
146	>	32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
147	>	in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
148	>	firing during backup and restore.
149	>
150	>	33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
151	>	for verbose output using the new property "StatisticsRequested".
152	>	see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
153	>
154	>	34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
155	>
156	>	35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
157	>	palette. This uses the online validation feature added in Firebird 2.5. The
158	>	services's properties enable inclusion/exclusion of tables and indexes using
159	>	regular expressions. See.
160	>	https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
161	>
162	>	36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
163	>	option on a database.
164	>
165	>	37. TIBCustomService: Assign method implemented to allow copying of service login
166	>	context between service API components. "Detach" method now only detaches
167	>	service when last reference to the service interface detaches. Tidy up of
168	>	code for SetActive and Attach methods including password hiding.
169	>
170	>	38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
171	>	and used to determine the auth method and protocol used for the connection.
172	>
173	>	39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
174	>	a Create Database Statement generated by IBX.
175	>
176	>	40. All IBServices now have an additional published property "PortNo". This may
177	>	be set to a non-standard port number when necessary. If zero then the default
178	>	port number is used.
179	>
180	>	41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
181	>	and not just the mouse.
182	>
183	>	42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
184	>
185	>	43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
186	>	image index and selected image index for each node to be set from a database field.
187	>
188	>	44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
189	>	then database schema includes grants to all users. If not present then the
190	>	only user grants included are those to User PUBLIC.
191	>
192	>	45. TIBTreeView: performance improvement. When expanding include both expanded node
193	>	and child nodes in dataset.
194
27	–	8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
28	–	values are no longer converted to milliseconds from TDateTime and then back again
29	–	the TDateTime (the TDataset approach).
