2  
3 < 1. IBExtract: Identity columns - add addition check for null column for generator name.
3 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
4 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
5 >
6 > 2. TIBSQL: Batch Update/Insert support added.
7 >
8 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
9 >   is no longer automatically converted to upper case when it is syntactically a
10 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
11 >   as CREATE PROCEDURE "iCASE".
12 >
13 >   There could be a backwards compatibility issue when the StoredProcName was entered
14 >   manually at design time. That is not selected from the drop down list. If the
15 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
16 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
17 >   ensure that the value of the StoredProcName is all upper case, unless it was
18 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
19 >   quotes).
20 >
21 >   Note that when a stored procedure name was declared delimited in double quotes,
22 >   as in the first example above, the value of the StoredProcName property must not
23 >   include the delimiters (double quotes).
24 >
25 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
26 >   upgrade.conf was not found. This replaces silently ignoring the problem.
27 >
28 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
29 >   'Version.%.3d' and is used to generate the section header names (for a given
30 >   version no.) in the upgrade.conf file.
31 >
32 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
33 >
34 > 1. -c command line option added to fbsql example program. Used to set connection
35 >   character set.
36 >
37 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
38 >
39 > 1. Firebird 4 support added.
40 >
41 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
42 >   extended precision NUMERIC fields are supported.
43 >
44 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
45 >
46 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
47 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
48 >
49 > 5. IBExtract now supports FB4 enhancements:
50 >   - new data types as above
51 >   - Identity column extensions
52 >   - Default user role
53 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
54 >   - Internal Functions
55 >
56 > 6. IBExtract: new event: OnExtractLines.
57 >
58 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
59 >
60 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
61 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
62 >
63 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
64 >   format for rendering a time zone.
65 >
66 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
67 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
68 >
69 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
70 >    IIBGUIInterface and IIBTimerInf respectively.
71 >
72 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
73 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
74 >
75 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
76 >    truncated to its fixed character width rather than being right padded with
77 >    white space to the maximum data size.
78 >
79 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
80 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
81 >    also empty.
82 >
83 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
84 >
85 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
86 >    connect string. The database name is extracted from the connect string.
87 >
88 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
89 >
90 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
91 >
92 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
93 >    not being present as required.
94 >
95 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
96 >    version that can be customised to work with other database drivers.
97 >
98 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
99 >    unnecessary CR at end of line on Unix platforms.
100 >
101 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
102 >    seconds in order to reduce risk of message loss.
103 >
104 > 23. ISQLMonitor: read and write count statistics now available via:
105 >      property TIBSQLMonitor.ReadCount;
106 >      IIBSQLMonitorHook.GetWriteCount: integer;
107 >
108 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
109 >
110 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
111 >
112 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
113 >    number of UTF8 characters exceeds the string size then string is truncated
114 >    to the maximum string size. This is  usually a problem with fixed width columns
115 >    right padded with white space.
116 >
117 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
118 >    If SQLFiltered is set then when a dataset is opened, each line in the
119 >    SQLFilterParams property is assumed to be a SQL condition clause and
120 >    ANDed into the Where clause of the SQL Select statement provided as a
121 >    dataset property. Each such SQL condition thus acts as an additional filter
122 >    on the dataset.
123 >
124 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
125 >    side filters).
126 >
127 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
128 >   text matches complete entry.
129 >
130 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
131 >   dataset are active (avoids risk of access violation if master is inactive)
132 >
133 > 6. TIBEvents: Registered property can now be set at design time even if database not open
134 >
135 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
136 >   This should prevent "spillover" of events between sessions.
137 >
138 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
139 >   This should ensure that the internal buffer is set up correctly and avoids
140 >   a duplicate initial row.
141 >
142 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
143 >   That is, the DataSize should be the field size * character set width. The
144 >   value returned by DataSize is now the same as the Dataset buffer size reserved
145 >   for the field.
146 >
147 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
148 >
149 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
150 >    and vice-versa. This may result in an exception being raised (correctly) for
151 >    older programs when using dataset fields added to a form and the database has been
152 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
153 >    In such cases, the field needs to be deleted in the IDE fields editor and then
154 >    added back in.
155 >
156 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
157 >    false if query contains only white space and not just empty.
158 >
159 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
160 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
161 >    is cancelled.
162 >
163 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
164 >    called on a null field.
165 >
166 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
167 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
168 > set.
169 >
170 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
171 >    a cached update is applied and an exception is raised.
172 >
173 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
174 >
175 > 17. Console Mode Local Database support: backup/restore should now work correctly.
176 >
177 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
178 >    possible and an exception raised.
179 >
180 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
181 >    below this version no. and upgrade not possible.
182 >
183 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
184 >
185 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
186 >    not SQL Identifiers are now supported.
187 >
188 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
189 >    passed to the Firebird engine for execution.
190 >
191 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
192 >    is made to scroll back.
193 >
194 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
195 >
196 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
197 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
198 >
199 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
200 >   validated. If no match is found in the list of field names and the database has
201 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
202 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
203 >
204 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
205 >   with fpc 3.2.
206 >
207 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
208 >
209 >
210 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
211 >   and is used to override the default settings in the client side "firebird.conf" This
212 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
213 >   Each line of the string list should be a setting in the same format as "firebird.conf".
214 >   For example "WireCompression = true" in order to request wire compression on the client side.
215 >
216 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
217 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
218 >   also require a compatible setting in the server side "firebird.conf". For example
219 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
220 >   compression to be used.
221 >
222 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
223 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
224 >   ibx/examples/dbinfo for examples of how to display this information.
225 >
226 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
227 >   is a "convenience" property. If set the "WireCompression=true" is added to the
228 >   ConfigOverrides. If unchecked then this setting is removed.
229 >
230 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
231 >   not "INT64".
232 >
233 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
234 >   These are:
235 >    property TimestampFormat: string;
236 >    property DateFormat: string;
237 >    property TimeFormat: string;
238 >
239 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
240 >   DATETIME and TIME. The format strings use the standard FPC date/time format
241 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
242 >
243 >   If any of the above properties are set to an empty string, then the locale default
244 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
245 >   locale default is extended by appending '.zzz' to include milliseconds.
246 >
247 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
248 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
249 >
250 > 5. New published property for TIBCSVDataOut:
251 >     property QuoteStrings: boolean (default true)
252 >
253 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
254 >   used to delimit each and every string in the output.
255 >
256 > 6. New published properties for TIBCSVDataOut:
257 >    property FieldSeparator: string;
258 >    property HeaderSeparator: string;
259 >
260 >   Respectively, these provide the separator character(s) used to separate fields
261 >   in data and header rows. Both default to ','.
262 >
263 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
264 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
265 >    property OnFormatTextString;
266 >
267 >   This event handler can be used to process text strings before they are included
268 >   in the output e.g. to replace unprintable characters with alternative strings.
269 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
270 >
271 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
272 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
273 >   and without raising and exception if it does not.
274 >
275 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
276 >   consistency with SQL queries.
277 >
278 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
279 >    When true, SQL statement parameter names are parsed case sensitive. Note for
280 >    TIBDataSet only applies to Select query.
281 >
282 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
283 >    an IDE exception.
284 >
285 > 12. LocalDBSupport: initial database creation should now work correctly
286 >    when the schema source is an sql file.
287 >
288 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
289 >    when defined, this handler will be called by the internal TIBXScript during
290 >    initial database creation when the schema source is an sql file and may be used
291 >    to provide a visual indication of progress in console mode.
292 >
293 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
294 >    to true while a new local database is being created and its schema populated.
295 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
296 >    when the database is disconnected/connected during the create DB procedure.
297 >
298 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
299 >    are now always ignored and replaced by the user name and password provided as
300 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
301 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
302 >    completely ignored if this property is true.
303 >
304 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
305 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
306 >    ImageIndex and SelectImageIndex values on AddNode.
307 >
308 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
309 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
310 >    the same database connection.
311 >
312 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
313 >    if provided, this should be an conditional SQL expression suitable for
314 >    including in an SQL Select statement "where" clause. If non-empty and the
315 >    "Filtered" property is true then the SQL expression provided as the value of
316 >    the "Filter" property is "ANDed" with any existing condition statement
317 >    in the SQL statement's "Where" clause.
318 >
319 >    If the "Filter" property is set at run time, the "Filtered" property is true
320 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
321 >
322 >    The "Filter" condition may include IBX style parameters. In which case, their
323 >    value must be set by the dataset's "OnBeforeOpen" event handler.
324 >
325 >    This is a public property for TIBDataSet and TIBQuery query and intended for
326 >    use at run time.
327 >
328 >    Note: The property is a published property of TIBTable. The TIBTable functionality
329 >    is unaffected by this change.
330 >
331 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
332 >
333 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
334 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
335 >   mode apps.
336 >
337 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
338 >   statement. This avoids problems if "Execute Block" is used as the Query.
339 >
340 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
341 >   internal SQL tokeniser routines.
342 >
343 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
344 >   as a select statement, with or without CTEs.
345 >
346 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
347 >
348 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
349 >   internal SQL tokeniser routines.
350 >
351 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
352 >    being raised for valid set statements processed by a data formatter.
353 >
354 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
355 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
356 >   the path of the Firebird Library used by the database/services connection.
357 >
358 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
359 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
360 >   services connection.
361 >
362 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
363 >   or param name is not a valid SQL identifier.
364 >
365 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
366 >    view of whether the text box should be editable when no DataSource is specified.
367 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
368 >    ReadOnly is false, the text box is editable when no DataSource is specified.
369 >
370 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
371 >    the FBLIB environment variable. If you do not want to permit this then you
372 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
373 >    this setting.

381 >
382 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
383 > all previous copies of the IBX source code tree before installing this release.
384 >
385 > The IBX packages used by most users have not changed, with one exception. The
386 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
387 > to use the IBServices unit in your applications, please add the iblegacyServices
388 > to the list of dependencies. To do this, open the Project Inspector and select
389 > Add->New Requirement and select "ibLegacyServices" from the list of available
390 > packages.
391 >
392 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
393 >   the IBServices unit providing what is intended to be a clearer and easier to
394 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
395 >   more information and the guide to "Firebird Service Management Using IBX".
396 >   As indicated above, the legacy services components are still available and
397 >   provided in a separate package. There is no need to update working applications
398 >   using the older versions except for an additional package dependency.
399 >
400 > 2. The IBX packages and source code tree have been re-organised in an attempt to
401 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
402 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
403 >   new set of IBX packages.
404 >
405 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
406 >   updated to use the new Services API components.
407 >
408 > 4. The iblocal package has been updated to use the new Services API components.
409 >
410 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
411 >   TIBXSecurityService. It had been wrongly classified in the previous version
412 >   as a per database configuration item. It is global to a server and hence
413 >   correctly positioned as part of the Security Package. In the DBAdmin example,
414 >   the setting has moved to the mappings page.
415 >
416 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
417 >   are ignored.
418 >
419 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
420 >   closed before the database is dropped. Before and After Disconnect event handlers
421 >   are also fired.

536 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
537 >
538 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
539 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
540 > RELEASE.
541 >
542 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
543 >
544 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
545  
546   2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
547     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
548 <   information). Values returned as a result of executing an Insert or Update statement
549 <   replace existing values in the current row for each corresponding column.
548 >   information). However, this is also a very useful mechanism for returning updated computed by
549 >   column values. Values returned as a result of executing an Insert or Update statement
550 >   replace existing values in the current row for each corresponding column.
551 >
552 >   Previously, if a dataset's select query included read only (computed by) fields then
553 >   an automatic row refresh was performed after an insert or update query had been processed,
554 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
555 >   that an automatic refresh is no longer performed if an insert or update query contains
556 >   a returning clause that updates one or more fields on the current row. A full row
557 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
558 >   field values and the select query contains read only fields. Use of Insert/update
559 >   returning should be significantly more efficient than executing a refresh query.
560 >
561 >   This behaviour change is intended to be backwards compatible and there should be no need to change
562 >   existing programs, other than to improve performance by using the new capability.
563 >
564 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
565 >   they are called when the dataset row is being deleted, there is no value in
566 >   updating the current record from the query result. Instead, a new event handler
567 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
568 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
569 >   by the query. The event handler can then interrogate the query results and
570 >   perform whatever action is necessary. For example to confirm, to the user,
571 >   the deletion of a row with the returned values.
572  
573 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
573 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
574 >   any Computed By or Identity Columns. The IBTables example has been updated to
575 >   illustrate the computation of the employee Full Name on update.
576 >
577 > 5. TIBTable: The GeneratorField property is now published.
578 >
579 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
580     When InsertSQL is generated, the Identity columns are not included in the list of values to
581     be inserted. A RETURNING clause is added to the insert statement to return the value of
582     each Identity column after the insert is executed.
583  
584 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
585 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
586 +   Insert..Returning clause.
587 +
588 + 8. TIBGenerator: small performance improvement by not preparing query each time
589 +   a new value is generated.
590 +
591 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
592 +
593 + 10. Property editors will now sync table name to a System Table when "Include System
594 +    Tables" is selected and the query is for a System Table.
595 +
596 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
597 +    values are no longer converted to milliseconds from TDateTime and then back again
598 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
599 +
600 + 12. Property Editors handling of Stored Procedures.
601 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
602 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
603 +      query).
604 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
605 +
606 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
607 +    can be used to select a package. If non-empty, the stored procedure name is
608 +    expected to be a stored procedure defined in the specified package and the
609 +    generated SQL will be as required for a stored procedure located in a package.
610 +
611 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
612 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
613 +    which a stored procedure can be selected. With no package name selected, non-package
614 +    stored procedures are listed.
615 +
616 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
617 +    for password on reconnect.
618 +
619 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
620 +    and character set name.
621 +
622 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
623 +    DB info lookups"
624 +
625 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
626 +
627 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
628 +
629 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
630 +    parameters. This stops an exception being raised when the field cannot be
631 +    located in the record buffer.
632 +
633 + 21. Property Editors now automatically include System Tables when opened and when the query table
634 +    is a System Table.
635 +
636 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
637 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
638 +
639 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
640 +    add the SPB item isc_spb_expected_db. This names a database using
641 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
642 +    database. examples/services re-written to illustrate use of "expected_db".
643 +
644 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
645 +    This avoids truncated backups when the server returns a timeout (busy) response.
646 +
647 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
648 +
649 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
650 +    databasenames. These are respectively expanded to the local system's temp directory
651 +    (including trailing delimiter) or to a prescribed data directory (including
652 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
653 +    in the user's home directory. The hidden directory name is either the string returned
654 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
655 +    Under Windows, the directory is the same as the Data Directory as decribed
656 +    above but instead prefixed by the User's application data path. These may be
657 +    used to improve application portability for Personal Databases.
658 +
659 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
660 +    this has not worked for a long time and is not useful either. FieldDefs should be
661 +    managed using the Fields Editor as with any other dataset. To access the fields
662 +    editor for a TIBTable component, double click on the component. The fields editor
663 +    is then displayed.
664 +
665 + 28. TIBDatabaseInfo: new properties/function
666 +     * DateDBCreated (returns date/time database created)
667 +     * TransactionCount (returns no. of active transactions)
668 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
669 +     * PagesFree (Firebird 3 or later)
670 +     * PagesUsed (Firebird 3 or later)
671 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
672 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
673 +
674 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
675 +
676 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
677 +
678 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
679 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
680 +
681 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
682 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
683 +    firing during backup and restore.
684 +
685 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
686 +    for verbose output using the new property "StatisticsRequested".
687 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
688 +
689 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
690 +
691 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
692 +    palette. This uses the online validation feature added in Firebird 2.5. The
693 +    services's properties enable inclusion/exclusion of tables and indexes using
694 +    regular expressions. See.
695 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
696 +
697 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
698 +    option on a database.
699 +
700 + 37. TIBCustomService: Assign method implemented to allow copying of service login
701 +    context between service API components. "Detach" method now only detaches
702 +    service when last reference to the service interface detaches. Tidy up of
703 +    code for SetActive and Attach methods including password hiding.
704 +
705 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
706 +    and used to determine the auth method and protocol used for the connection.
707 +
708 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
709 +    a Create Database Statement generated by IBX.
710 +
711 + 40. All IBServices now have an additional published property "PortNo". This may
712 +    be set to a non-standard port number when necessary. If zero then the default
713 +    port number is used.
714 +
715 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
716 +    and not just the mouse.
717 +
718 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
719 +
720 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
721 +    image index and selected image index for each node to be set from a database field.
722 +
723 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
724 +    then database schema includes grants to all users. If not present then the
725 +    only user grants included are those to User PUBLIC.
726 +
727 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
728 +    and child nodes in dataset.
729 +
730 +
