24 > IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
25 >
26 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
27 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
28 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
29 >      ISSUES TO support@mwasoftware.co.uk
30 >
31 > 1. Complete rewrite of internal buffer management in order to improve performance
32 >   and maintainability. Highlights:
33 >
34 >   * Extending the size of the buffer pool no longer has to copy the entire record
35 >     cache. Instead, a new extent is simply added to the buffer pool.
36 >   * A memory to memory copy of each display buffer now is avoided when scolling the
37 >     dataset.
38 >   * A separate set of buffers is now used for calculated fields. This avoids
39 >     having to keep copies of calculated field values in the buffer cache.
40 >   * Compact bitmaps are used to record null status and need to refresh in each
41 >     buffer.
42 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
43 >     buffer type in FCL-DB.
44 >
45 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
46 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
47 >
48 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
49 >   If either or both of these flags are set at design time (using the fields editor)
50 >   then this forces a row refresh on respectively insert or update, or both, when the
51 >   corresponding field is not present in an SQL RETURNING clause.
52 >
53 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
54 >   maintainability and readability and to add identification of primary key fields.
55 >
56 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
57 >   as a refresh of the current row. However, this is different behaviour to that described
58 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
59 >   the dataset from the underlying database, and attempts to reposition the cursor on
60 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
61 >
62 > 6. A progammatic Row Refresh should no longer be required.
63 >   Use Insert/Update... returning to refresh any fields that may change following an
64 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
65 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
66 >   for the field at Design Time to force a row refresh if not in the returning clause.
67 >
68 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
69 >
70 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
71 >   This gives the number of buffers in the initial block for the buffer pool in
72 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
73 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
74 >   for small datasets.
75 >
76 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
77 >
78 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
79 >
80 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
81 >
82 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
83 >
84 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
85 >
86 > 1. TIBTransaction: new properties
87 >    property TransactionID: integer read GetTransactionID;
88 >    property IsReadOnly: boolean read GetIsReadOnly;
89 >    {published}
90 >    property TransactionName: string read FTransactionName write SetTransactionName;
91 >
92 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
93 >   Insert or Update...Returning. This allows blobs and arrays to be returned
94 >   by the statement.
95 >
96 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
97 >
98 > 4. TransactionName initialised to a newly generated GUID if empty.
99 >
100 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
101 >   for the fbintf package's journaling capability. TIBJournal is used to set the
102 >   file path and filename for the journal file and to Enabled (start journaling) and
103 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
104 >   more information, and comments in IBJournal.pas.
105 >
106 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
107 >
108 > 7. Bug fix: blob id no longer set to null on update when blob has not been
109 >   retrieved.
110 >
111 > 8. Row auto refreshed on update/insert if blob or array field updated and field
112 >   not in a returning clause.
113 >
114 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
115 >   buffer overhead and avoids problem when refresh query has a different column
116 >   count to select query i.e. incorrectly changing number of columns.
117 >
118 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
119 >
120 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
121 >    string. Note that the Version property returns an InterBase compatible version string.
122 >
123 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
124 >
125 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
126 >
127 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
128 >   This is for compatibility with Firebird 5 where Update...Returning can return
129 >   a cursor.
130 >
131 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
132 >
133 > 1. Add try-..except check when initially loading library in IDE. This should
134 > ensure that IDE continues to load even when a failure occurs in IBX load
135 > library.
136 >
137 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
138 >   hence will correctly detect end of the outer containing block when the block
139 >   contains a SELECT ... CASE ... END construct.
140 >
141 > 3. IBExtract: some further tidying up to remove extraneous white space.
142 >
143 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
144 >   errors when extra elements are added to DB.TFieldType.
145 >
146 > 5. IBUpdate: updated to reflect changes to ISQLParam.
147 >
148 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
149 >
150 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
151 >
152 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
153 >
154 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
155 >
156 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
157 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
158 >
159 > 2. TIBSQL: Batch Update/Insert support added.
160 >
161 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
162 >   is no longer automatically converted to upper case when it is syntactically a
163 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
164 >   as CREATE PROCEDURE "iCASE".
165 >
166 >   There could be a backwards compatibility issue when the StoredProcName was entered
167 >   manually at design time. That is not selected from the drop down list. If the
168 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
169 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
170 >   ensure that the value of the StoredProcName is all upper case, unless it was
171 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
172 >   quotes).
173 >
174 >   Note that when a stored procedure name was declared delimited in double quotes,
175 >   as in the first example above, the value of the StoredProcName property must not
176 >   include the delimiters (double quotes).
177 >
178 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
179 >   upgrade.conf was not found. This replaces silently ignoring the problem.
180 >
181 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
182 >   'Version.%.3d' and is used to generate the section header names (for a given
183 >   version no.) in the upgrade.conf file.
184 >
185 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
186 >
187 > 1. -c command line option added to fbsql example program. Used to set connection
188 >   character set.
189 >
190 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
191 >
192 > 1. Firebird 4 support added.
193 >
194 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
195 >   extended precision NUMERIC fields are supported.
196 >
197 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
198 >
199 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
200 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
201 >
202 > 5. IBExtract now supports FB4 enhancements:
203 >   - new data types as above
204 >   - Identity column extensions
205 >   - Default user role
206 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
207 >   - Internal Functions
208 >
209 > 6. IBExtract: new event: OnExtractLines.
210 >
211 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
212 >
213 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
214 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
215 >
216 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
217 >   format for rendering a time zone.
218 >
219 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
220 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
221 >
222 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
223 >    IIBGUIInterface and IIBTimerInf respectively.
224 >
225 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
226 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
227 >
228 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
229 >    truncated to its fixed character width rather than being right padded with
230 >    white space to the maximum data size.
231 >
232 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
233 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
234 >    also empty.
235 >
236 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
237 >
238 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
239 >    connect string. The database name is extracted from the connect string.
240 >
241 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
242 >
243 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
244 >
245 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
246 >    not being present as required.
247 >
248 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
249 >    version that can be customised to work with other database drivers.
250 >
251 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
252 >    unnecessary CR at end of line on Unix platforms.
253 >
254 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
255 >    seconds in order to reduce risk of message loss.
256 >
257 > 23. ISQLMonitor: read and write count statistics now available via:
258 >      property TIBSQLMonitor.ReadCount;
259 >      IIBSQLMonitorHook.GetWriteCount: integer;
260 >
261 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
262 >
263 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
264 >
265 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
266 >    number of UTF8 characters exceeds the string size then string is truncated
267 >    to the maximum string size. This is  usually a problem with fixed width columns
268 >    right padded with white space.
269 >
270 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
271 >    If SQLFiltered is set then when a dataset is opened, each line in the
272 >    SQLFilterParams property is assumed to be a SQL condition clause and
273 >    ANDed into the Where clause of the SQL Select statement provided as a
274 >    dataset property. Each such SQL condition thus acts as an additional filter
275 >    on the dataset.
276 >
277 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
278 >    side filters).
279 >
280 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
281 >   text matches complete entry.
282 >
283 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
284 >   dataset are active (avoids risk of access violation if master is inactive)
285 >
286 > 6. TIBEvents: Registered property can now be set at design time even if database not open
287 >
288 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
289 >   This should prevent "spillover" of events between sessions.
290 >
291 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
292 >   This should ensure that the internal buffer is set up correctly and avoids
293 >   a duplicate initial row.
294 >
295 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
296 >   That is, the DataSize should be the field size * character set width. The
297 >   value returned by DataSize is now the same as the Dataset buffer size reserved
298 >   for the field.
299 >
300 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
301 >
302 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
303 >    and vice-versa. This may result in an exception being raised (correctly) for
304 >    older programs when using dataset fields added to a form and the database has been
305 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
306 >    In such cases, the field needs to be deleted in the IDE fields editor and then
307 >    added back in.
308 >
309 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
310 >    false if query contains only white space and not just empty.
311 >
312 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
313 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
314 >    is cancelled.
315 >
316 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
317 >    called on a null field.
318 >
319 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
320 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
321 > set.
322 >
323 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
324 >    a cached update is applied and an exception is raised.
325 >
326 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
327 >
328 > 17. Console Mode Local Database support: backup/restore should now work correctly.
329 >
330 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
331 >    possible and an exception raised.
332 >
333 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
334 >    below this version no. and upgrade not possible.
335 >
336 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
337 >
338 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
339 >    not SQL Identifiers are now supported.
340 >
341 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
342 >    passed to the Firebird engine for execution.
343 >
344 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
345 >    is made to scroll back.
346 >
347 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
348 >
349 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
350 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
351 >
352 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
353 >   validated. If no match is found in the list of field names and the database has
354 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
355 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
356 >
357 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
358 >   with fpc 3.2.
359 >
360 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
361 >
362 >
363 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
364 >   and is used to override the default settings in the client side "firebird.conf" This
365 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
366 >   Each line of the string list should be a setting in the same format as "firebird.conf".
367 >   For example "WireCompression = true" in order to request wire compression on the client side.
368 >
369 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
370 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
371 >   also require a compatible setting in the server side "firebird.conf". For example
372 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
373 >   compression to be used.
374 >
375 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
376 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
377 >   ibx/examples/dbinfo for examples of how to display this information.
378 >
379 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
380 >   is a "convenience" property. If set the "WireCompression=true" is added to the
381 >   ConfigOverrides. If unchecked then this setting is removed.
382 >
383 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
384 >   not "INT64".
385 >
386 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
387 >   These are:
388 >    property TimestampFormat: string;
389 >    property DateFormat: string;
390 >    property TimeFormat: string;
391 >
392 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
393 >   DATETIME and TIME. The format strings use the standard FPC date/time format
394 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
395 >
396 >   If any of the above properties are set to an empty string, then the locale default
397 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
398 >   locale default is extended by appending '.zzz' to include milliseconds.
399 >
400 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
401 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
402 >
403 > 5. New published property for TIBCSVDataOut:
404 >     property QuoteStrings: boolean (default true)
405 >
406 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
407 >   used to delimit each and every string in the output.
408 >
409 > 6. New published properties for TIBCSVDataOut:
410 >    property FieldSeparator: string;
411 >    property HeaderSeparator: string;
412 >
413 >   Respectively, these provide the separator character(s) used to separate fields
414 >   in data and header rows. Both default to ','.
415 >
416 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
417 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
418 >    property OnFormatTextString;

420 >   This event handler can be used to process text strings before they are included
421 >   in the output e.g. to replace unprintable characters with alternative strings.
422 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
423 >
424 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
425 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
426 >   and without raising and exception if it does not.
427 >
428 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
429 >   consistency with SQL queries.
430 >
431 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
432 >    When true, SQL statement parameter names are parsed case sensitive. Note for
433 >    TIBDataSet only applies to Select query.
434 >
435 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
436 >    an IDE exception.
437 >
438 > 12. LocalDBSupport: initial database creation should now work correctly
439 >    when the schema source is an sql file.
440 >
441 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
442 >    when defined, this handler will be called by the internal TIBXScript during
443 >    initial database creation when the schema source is an sql file and may be used
444 >    to provide a visual indication of progress in console mode.
445 >
446 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
447 >    to true while a new local database is being created and its schema populated.
448 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
449 >    when the database is disconnected/connected during the create DB procedure.
450 >
451 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
452 >    are now always ignored and replaced by the user name and password provided as
453 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
454 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
455 >    completely ignored if this property is true.
456 >
457 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
458 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
459 >    ImageIndex and SelectImageIndex values on AddNode.
460 >
461 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
462 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
463 >    the same database connection.
464 >
465 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
466 >    if provided, this should be an conditional SQL expression suitable for
467 >    including in an SQL Select statement "where" clause. If non-empty and the
468 >    "Filtered" property is true then the SQL expression provided as the value of
469 >    the "Filter" property is "ANDed" with any existing condition statement
470 >    in the SQL statement's "Where" clause.
471 >
472 >    If the "Filter" property is set at run time, the "Filtered" property is true
473 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
474 >
475 >    The "Filter" condition may include IBX style parameters. In which case, their
476 >    value must be set by the dataset's "OnBeforeOpen" event handler.
477 >
478 >    This is a public property for TIBDataSet and TIBQuery query and intended for
479 >    use at run time.
480 >
481 >    Note: The property is a published property of TIBTable. The TIBTable functionality
482 >    is unaffected by this change.

484 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
485 >
486 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
487 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
488 >   mode apps.
489 >
490 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
491 >   statement. This avoids problems if "Execute Block" is used as the Query.
492 >
493 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
494 >   internal SQL tokeniser routines.
495 >
496 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
497 >   as a select statement, with or without CTEs.
498 >
499 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
500 >
501 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
502 >   internal SQL tokeniser routines.
503 >
504 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
505 >    being raised for valid set statements processed by a data formatter.
506 >
507 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
508 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
509 >   the path of the Firebird Library used by the database/services connection.
510 >
511 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
512 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
513 >   services connection.
514 >
515 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
516 >   or param name is not a valid SQL identifier.
517 >
518 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
519 >    view of whether the text box should be editable when no DataSource is specified.
520 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
521 >    ReadOnly is false, the text box is editable when no DataSource is specified.
522 >
523 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
524 >    the FBLIB environment variable. If you do not want to permit this then you
525 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
526 >    this setting.

529 >
530 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
531 >   Utf8EscapeControlChars
532 >
533 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
534 >
535 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
536 > all previous copies of the IBX source code tree before installing this release.
537 >
538 > The IBX packages used by most users have not changed, with one exception. The
539 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
540 > to use the IBServices unit in your applications, please add the iblegacyServices
541 > to the list of dependencies. To do this, open the Project Inspector and select
542 > Add->New Requirement and select "ibLegacyServices" from the list of available
543 > packages.
544 >
545 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
546 >   the IBServices unit providing what is intended to be a clearer and easier to
547 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
548 >   more information and the guide to "Firebird Service Management Using IBX".
549 >   As indicated above, the legacy services components are still available and
550 >   provided in a separate package. There is no need to update working applications
551 >   using the older versions except for an additional package dependency.
552 >
553 > 2. The IBX packages and source code tree have been re-organised in an attempt to
554 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
555 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
556 >   new set of IBX packages.
557 >
558 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
559 >   updated to use the new Services API components.
560 >
561 > 4. The iblocal package has been updated to use the new Services API components.
562 >
563 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
564 >   TIBXSecurityService. It had been wrongly classified in the previous version
565 >   as a per database configuration item. It is global to a server and hence
566 >   correctly positioned as part of the Security Package. In the DBAdmin example,
567 >   the setting has moved to the mappings page.
568 >
569 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
570 >   are ignored.
571 >
572 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
573 >   closed before the database is dropped. Before and After Disconnect event handlers
574 >   are also fired.
575 >
576 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
577 >   is started and not just the first time.
578 >
579 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
580 >   depenendency with comp type.
581 >
582 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
583 >
584 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
585 >    then this is recognised and not ignored.
586 >
587 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
588 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
589 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
590 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
591 >
592 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
593 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
594 >    counters for the select query. Note: stats accumulate after each fetch from
595 >    the database. To get total query cost after open, call the "Last" method
596 >    and then GetPerfStatistics.
597 >
598 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
599 >
600 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
601 >    in parenthesises.
602 >
603 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
604 >    SQL identifiers are always delimited by double quotes. If false, then they are
605 >    only delimited if the identifier is a reserved word, contains lower case or special
606 >    characters. Set this property to true to retain previous behaviour.
607 >
608 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
609 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
610 >
611 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
612 >       property MasterDetailDelay: integer {defaults to zero}
613 >
614 >    When non-zero and the dataset is a detail table referencing a master table
615 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
616 >    then a synchronisation delay is added (in milliseconds) between the master
617 >    row changing and the detail dataset being re-opened. If the master dataset
618 >    is scrolled before the delay expires then the delay is reset. This can be used
619 >    to avoid performance overheads when scrolling through a large master dataset.
620 >
621 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
622 >    chreads unit must be included in your project. TTimer is not used in order
623 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
624 >
625 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
626 >    with Extract Option eoDatabase.
627 >
628 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
629 >    When a deLayoutChanged event is reported on the ListSource dataset, the
630 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
631 >    relationship with the control's datasource (master).
632 >
633 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
634 >
635 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
636 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
637 >
638 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
639 >    DDL (Firebird 3 and later only).
640 >
641 > 22. TIBLookupComboBox Autocomplete Fixes:
642 >    i. Only appended text is now selected after autocomplete.
643 >    ii. Uppercase keys no longer ignored for autocomplete.
644 >    iii. Retain Prefix case is now honoured correctly.
645 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
646 >        before autocomplete performed. i.e. behaviour now the same as when
647 >        no DataSource assigned.
648 >
649 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
650 >    between SQL statements.
651 >
652 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
653 >    ObjectNames are converted to upper case before matching against metadata object
654 >    names, unless the objectname is delimited by double quotes, in which case, the
655 >    double quotes are removed and the remaining string is used (unmodified) to match
656 >    against the metadata object name.
657 >
658 >    If true then the ObjectName is used as is without modification and matched
659 >    against the metadata object name. No attempt is made to remove double quotes.
660 >
661 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
662 >    with eoTrigger, these extract types can be used to select only Database Triggers,
663 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
664 >
665 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
666 >    statement separate character is now reset to the default (';').
667 >
668 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
669 >
670 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
671 >    a commit or reconnect statement and instead activated only when next SQL statement
672 >    is executed.
673 >
674 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
675 >
676 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
677 >    converting statement to upper case.
678 >
679 > 31. TIBExtract: metadata comments now supported. New published property
680 >    IncludeMetaDataComments (default true). If true then metadata comments included
681 >    in extracted DDL. New Extract Object member eoComments. This may be used with
682 >    ExtractObject method to list all metadata comments.
683 >
684 > 32. TIBExtract: ListObjectNames method added.
685 >
686 > 33. Updated Database component editor to support additional connection string
687 >    types.
688 >
