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 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
42 > 5. TIBTable: The GeneratorField property is now published.
43 >
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 + 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 + 8. TIBGenerator: small performance improvement by not preparing query each time
54 +   a new value is generated.
55 +
56 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
57 +
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 +
