1 + IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
2 +
3 + NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
4 +      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
5 +      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
6 +      ISSUES TO support@mwasoftware.co.uk
7 +
8 + 1. Complete rewrite of internal buffer management in order to improve performance
9 +   and maintainability. Highlights:
10 +
11 +   * Extending the size of the buffer pool no longer has to copy the entire record
12 +     cache. Instead, a new extent is simply added to the buffer pool.
13 +   * A memory to memory copy of each display buffer now is avoided when scolling the
14 +     dataset.
15 +   * A separate set of buffers is now used for calculated fields. This avoids
16 +     having to keep copies of calculated field values in the buffer cache.
17 +   * Compact bitmaps are used to record null status and need to refresh in each
18 +     buffer.
19 +   * Display buffer type changed from PChar to TRecordBuffer in line with change of
20 +     buffer type in FCL-DB.
21 +
22 + 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
23 +   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
24 +
25 + 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
26 +   If either or both of these flags are set at design time (using the fields editor)
27 +   then this forces a row refresh on respectively insert or update, or both, when the
28 +   corresponding field is not present in an SQL RETURNING clause.
29 +
30 + 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
31 +   maintainability and readability and to add identification of primary key fields.
32 +
33 + 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
34 +   as a refresh of the current row. However, this is different behaviour to that described
35 +   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
36 +   the dataset from the underlying database, and attempts to reposition the cursor on
37 +   the same record as it was". IBX now complies with the FPC definition of Refresh.
38 +
39 + 6. A progammatic Row Refresh should no longer be required.
40 +   Use Insert/Update... returning to refresh any fields that may change following an
41 +   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
42 +   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
43 +   for the field at Design Time to force a row refresh if not in the returning clause.
44 +
45 + 7. It should now be possible to insert a row into an empty unidirectional dataset.
46 +
47 + 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
48 +   This gives the number of buffers in the initial block for the buffer pool in
49 +   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
50 +   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
51 +   for small datasets.
52 +
53 + IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
54 +
55 + 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
56 +
57 + 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
58 +
59 + 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
60 +
61 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
62 +
63 + 1. TIBTransaction: new properties
64 +    property TransactionID: integer read GetTransactionID;
65 +    property IsReadOnly: boolean read GetIsReadOnly;
66 +    {published}
67 +    property TransactionName: string read FTransactionName write SetTransactionName;
68 +
69 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
70 +   Insert or Update...Returning. This allows blobs and arrays to be returned
71 +   by the statement.
72 +
73 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
74 +
75 + 4. TransactionName initialised to a newly generated GUID if empty.
76 +
77 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
78 +   for the fbintf package's journaling capability. TIBJournal is used to set the
79 +   file path and filename for the journal file and to Enabled (start journaling) and
80 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
81 +   more information, and comments in IBJournal.pas.
82 +
83 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
84 +
85 + 7. Bug fix: blob id no longer set to null on update when blob has not been
86 +   retrieved.
87 +
88 + 8. Row auto refreshed on update/insert if blob or array field updated and field
89 +   not in a returning clause.
90 +
91 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
92 +   buffer overhead and avoids problem when refresh query has a different column
93 +   count to select query i.e. incorrectly changing number of columns.
94 +
95 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
96 +
97 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
98 +    string. Note that the Version property returns an InterBase compatible version string.
99 +
100 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
101 +
102 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
103 +
104 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
105 +   This is for compatibility with Firebird 5 where Update...Returning can return
106 +   a cursor.
107 +
108 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
109 +
110 + 1. Add try-..except check when initially loading library in IDE. This should
111 + ensure that IDE continues to load even when a failure occurs in IBX load
112 + library.
113 +
114 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
115 +   hence will correctly detect end of the outer containing block when the block
116 +   contains a SELECT ... CASE ... END construct.
117 +
118 + 3. IBExtract: some further tidying up to remove extraneous white space.
119 +
120 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
121 +   errors when extra elements are added to DB.TFieldType.
122 +
123 + 5. IBUpdate: updated to reflect changes to ISQLParam.
124 +
125 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
126 +
127 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
128 +
129 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
130 +
131 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
132 +
133 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
134 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
135 +
136 + 2. TIBSQL: Batch Update/Insert support added.
137 +
138 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
139 +   is no longer automatically converted to upper case when it is syntactically a
140 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
141 +   as CREATE PROCEDURE "iCASE".
142 +
143 +   There could be a backwards compatibility issue when the StoredProcName was entered
144 +   manually at design time. That is not selected from the drop down list. If the
145 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
146 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
147 +   ensure that the value of the StoredProcName is all upper case, unless it was
148 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
149 +   quotes).
150 +
151 +   Note that when a stored procedure name was declared delimited in double quotes,
152 +   as in the first example above, the value of the StoredProcName property must not
153 +   include the delimiters (double quotes).
154 +
155 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
156 +   upgrade.conf was not found. This replaces silently ignoring the problem.
157 +
158 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
159 +   'Version.%.3d' and is used to generate the section header names (for a given
160 +   version no.) in the upgrade.conf file.
161 +
162 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
163 +
164 + 1. -c command line option added to fbsql example program. Used to set connection
165 +   character set.
166 +
167 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
168 +
169 + 1. Firebird 4 support added.
170 +
171 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
172 +   extended precision NUMERIC fields are supported.
173 +
174 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
175 +
176 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
177 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
178 +
179 + 5. IBExtract now supports FB4 enhancements:
180 +   - new data types as above
181 +   - Identity column extensions
182 +   - Default user role
183 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
184 +   - Internal Functions
185 +
186 + 6. IBExtract: new event: OnExtractLines.
187 +
188 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
189 +
190 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
191 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
192 +
193 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
194 +   format for rendering a time zone.
195 +
196 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
197 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
198 +
199 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
200 +    IIBGUIInterface and IIBTimerInf respectively.
201 +
202 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
203 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
204 +
205 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
206 +    truncated to its fixed character width rather than being right padded with
207 +    white space to the maximum data size.
208 +
209 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
210 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
211 +    also empty.
212 +
213 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
214 +
215 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
216 +    connect string. The database name is extracted from the connect string.
217 +
218 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
219 +
220 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
221 +
222 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
223 +    not being present as required.
224 +
225 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
226 +    version that can be customised to work with other database drivers.
227 +
228 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
229 +    unnecessary CR at end of line on Unix platforms.
230 +
231 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
232 +    seconds in order to reduce risk of message loss.
233 +
234 + 23. ISQLMonitor: read and write count statistics now available via:
235 +      property TIBSQLMonitor.ReadCount;
236 +      IIBSQLMonitorHook.GetWriteCount: integer;
237 +
238 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
239 +
240 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
241 +
242 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
243 +    number of UTF8 characters exceeds the string size then string is truncated
244 +    to the maximum string size. This is  usually a problem with fixed width columns
245 +    right padded with white space.
246 +
247 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
248 +    If SQLFiltered is set then when a dataset is opened, each line in the
249 +    SQLFilterParams property is assumed to be a SQL condition clause and
250 +    ANDed into the Where clause of the SQL Select statement provided as a
251 +    dataset property. Each such SQL condition thus acts as an additional filter
252 +    on the dataset.
253 +
254 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
255 +    side filters).
256 +
257 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
258 +   text matches complete entry.
259 +
260 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
261 +   dataset are active (avoids risk of access violation if master is inactive)
262 +
263 + 6. TIBEvents: Registered property can now be set at design time even if database not open
264 +
265 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
266 +   This should prevent "spillover" of events between sessions.
267 +
268 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
269 +   This should ensure that the internal buffer is set up correctly and avoids
270 +   a duplicate initial row.
271 +
272 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
273 +   That is, the DataSize should be the field size * character set width. The
274 +   value returned by DataSize is now the same as the Dataset buffer size reserved
275 +   for the field.
276 +
277 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
278 +
279 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
280 +    and vice-versa. This may result in an exception being raised (correctly) for
281 +    older programs when using dataset fields added to a form and the database has been
282 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
283 +    In such cases, the field needs to be deleted in the IDE fields editor and then
284 +    added back in.
285 +
286 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
287 +    false if query contains only white space and not just empty.
288 +
289 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
290 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
291 +    is cancelled.
292 +
293 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
294 +    called on a null field.
295 +
296 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
297 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
298 + set.
299 +
300 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
301 +    a cached update is applied and an exception is raised.
302 +
303 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
304 +
305 + 17. Console Mode Local Database support: backup/restore should now work correctly.
306 +
307 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
308 +    possible and an exception raised.
309 +
310 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
311 +    below this version no. and upgrade not possible.
312 +
313 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
314 +
315 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
316 +    not SQL Identifiers are now supported.
317 +
318 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
319 +    passed to the Firebird engine for execution.
320 +
321 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
322 +    is made to scroll back.
323 +
324 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
325 +
326 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
327 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
328 +
329 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
330 +   validated. If no match is found in the list of field names and the database has
331 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
332 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
333 +
334 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
335 +   with fpc 3.2.
336 +
337 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
338 +
339 +
340 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
341 +   and is used to override the default settings in the client side "firebird.conf" This
342 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
343 +   Each line of the string list should be a setting in the same format as "firebird.conf".
344 +   For example "WireCompression = true" in order to request wire compression on the client side.
345 +
346 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
347 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
348 +   also require a compatible setting in the server side "firebird.conf". For example
349 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
350 +   compression to be used.
351 +
352 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
353 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
354 +   ibx/examples/dbinfo for examples of how to display this information.
355 +
356 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
357 +   is a "convenience" property. If set the "WireCompression=true" is added to the
358 +   ConfigOverrides. If unchecked then this setting is removed.
359 +
360 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
361 +   not "INT64".
362 +
363 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
364 +   These are:
365 +    property TimestampFormat: string;
366 +    property DateFormat: string;
367 +    property TimeFormat: string;
368 +
369 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
370 +   DATETIME and TIME. The format strings use the standard FPC date/time format
371 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
372 +
373 +   If any of the above properties are set to an empty string, then the locale default
374 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
375 +   locale default is extended by appending '.zzz' to include milliseconds.
376 +
377 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
378 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
379 +
380 + 5. New published property for TIBCSVDataOut:
381 +     property QuoteStrings: boolean (default true)
382 +
383 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
384 +   used to delimit each and every string in the output.
385 +
386 + 6. New published properties for TIBCSVDataOut:
387 +    property FieldSeparator: string;
388 +    property HeaderSeparator: string;
389 +
390 +   Respectively, these provide the separator character(s) used to separate fields
391 +   in data and header rows. Both default to ','.
392 +
393 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
394 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
395 +    property OnFormatTextString;
396 +
397 +   This event handler can be used to process text strings before they are included
398 +   in the output e.g. to replace unprintable characters with alternative strings.
399 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
400 +
401 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
402 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
403 +   and without raising and exception if it does not.
404 +
405 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
406 +   consistency with SQL queries.
407 +
408 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
409 +    When true, SQL statement parameter names are parsed case sensitive. Note for
410 +    TIBDataSet only applies to Select query.
411 +
412 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
413 +    an IDE exception.
414 +
415 + 12. LocalDBSupport: initial database creation should now work correctly
416 +    when the schema source is an sql file.
417 +
418 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
419 +    when defined, this handler will be called by the internal TIBXScript during
420 +    initial database creation when the schema source is an sql file and may be used
421 +    to provide a visual indication of progress in console mode.
422 +
423 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
424 +    to true while a new local database is being created and its schema populated.
425 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
426 +    when the database is disconnected/connected during the create DB procedure.
427 +
428 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
429 +    are now always ignored and replaced by the user name and password provided as
430 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
431 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
432 +    completely ignored if this property is true.
433 +
434 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
435 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
436 +    ImageIndex and SelectImageIndex values on AddNode.
437 +
438 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
439 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
440 +    the same database connection.
441 +
442 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
443 +    if provided, this should be an conditional SQL expression suitable for
444 +    including in an SQL Select statement "where" clause. If non-empty and the
445 +    "Filtered" property is true then the SQL expression provided as the value of
446 +    the "Filter" property is "ANDed" with any existing condition statement
447 +    in the SQL statement's "Where" clause.
448 +
449 +    If the "Filter" property is set at run time, the "Filtered" property is true
450 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
451 +
452 +    The "Filter" condition may include IBX style parameters. In which case, their
453 +    value must be set by the dataset's "OnBeforeOpen" event handler.
454 +
455 +    This is a public property for TIBDataSet and TIBQuery query and intended for
456 +    use at run time.
457 +
458 +    Note: The property is a published property of TIBTable. The TIBTable functionality
459 +    is unaffected by this change.

461 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
462 +
463 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
464 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
465 +   mode apps.
466 +
467 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
468 +   statement. This avoids problems if "Execute Block" is used as the Query.
469 +
470 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
471 +   internal SQL tokeniser routines.
472 +
473 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
474 +   as a select statement, with or without CTEs.
475 +
476 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
477 +
478 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
479 +   internal SQL tokeniser routines.
480 +
481 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
482 +    being raised for valid set statements processed by a data formatter.
483 +
484 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
485 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
486 +   the path of the Firebird Library used by the database/services connection.
487 +
488 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
489 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
490 +   services connection.
491 +
492 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
493 +   or param name is not a valid SQL identifier.
494 +
495 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
496 +    view of whether the text box should be editable when no DataSource is specified.
497 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
498 +    ReadOnly is false, the text box is editable when no DataSource is specified.
499 +
500 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
501 +    the FBLIB environment variable. If you do not want to permit this then you
502 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
503 +    this setting.

507 + 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
508 +   Utf8EscapeControlChars
