2 >
3 > 1. TIBTransaction: new properties
4 >    property TransactionID: integer read GetTransactionID;
5 >    property IsReadOnly: boolean read GetIsReadOnly;
6 >    {published}
7 >    property TransactionName: string read FTransactionName write SetTransactionName;
8 >
9 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
10 >   Insert or Update...Returning. This allows blobs and arrays to be returned
11 >   by the statement.
12 >
13 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
14 >
15 > 4. TransactionName initialised to a newly generated GUID if empty.
16 >
17 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
18 >   for the fbintf package's journaling capability. TIBJournal is used to set the
19 >   file path and filename for the journal file and to Enabled (start journaling) and
20 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
21 >   more information, and comments in IBJournal.pas.
22 >
23 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
24 >
25 > 7. Bug fix: blob id no longer set to null on update when blob has not been
26 >   retrieved.
27 >
28 > 8. Row auto refreshed on update/insert if blob or array field updated and field
29 >   not in a returning clause.
30 >
31 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
32 >   buffer overhead and avoids problem when refresh query has a different column
33 >   count to select query i.e. incorrectly changing number of columns.
34 >
35 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
36 >
37 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
38 >    string. Note that the Version property returns an InterBase compatible version string.
39 >
40 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
41 >
42 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
43 >
44 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
45 >   This is for compatibility with Firebird 5 where Update...Returning can return
46 >   a cursor.
47 >
48 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
49 >
50 > 1. Add try-..except check when initially loading library in IDE. This should
51 > ensure that IDE continues to load even when a failure occurs in IBX load
52 > library.
53 >
54 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
55 >   hence will correctly detect end of the outer containing block when the block
56 >   contains a SELECT ... CASE ... END construct.
57 >
58 > 3. IBExtract: some further tidying up to remove extraneous white space.
59 >
60 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
61 >   errors when extra elements are added to DB.TFieldType.
62 >
63 > 5. IBUpdate: updated to reflect changes to ISQLParam.
64 >
65 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
66 >
67 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
68 >
69 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
70 >
71 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
72 >
73 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
74 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
75 >
76 > 2. TIBSQL: Batch Update/Insert support added.
77 >
78 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
79 >   is no longer automatically converted to upper case when it is syntactically a
80 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
81 >   as CREATE PROCEDURE "iCASE".
82 >
83 >   There could be a backwards compatibility issue when the StoredProcName was entered
84 >   manually at design time. That is not selected from the drop down list. If the
85 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
86 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
87 >   ensure that the value of the StoredProcName is all upper case, unless it was
88 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
89 >   quotes).
90 >
91 >   Note that when a stored procedure name was declared delimited in double quotes,
92 >   as in the first example above, the value of the StoredProcName property must not
93 >   include the delimiters (double quotes).
94 >
95 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
96 >   upgrade.conf was not found. This replaces silently ignoring the problem.
97 >
98 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
99 >   'Version.%.3d' and is used to generate the section header names (for a given
100 >   version no.) in the upgrade.conf file.
101 >
102 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
103 >
104 > 1. -c command line option added to fbsql example program. Used to set connection
105 >   character set.
106 >
107 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
108 >
109 > 1. Firebird 4 support added.
110 >
111 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
112 >   extended precision NUMERIC fields are supported.
113 >
114 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
115 >
116 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
117 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
118 >
119 > 5. IBExtract now supports FB4 enhancements:
120 >   - new data types as above
121 >   - Identity column extensions
122 >   - Default user role
123 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
124 >   - Internal Functions
125 >
126 > 6. IBExtract: new event: OnExtractLines.
127 >
128 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
129 >
130 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
131 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
132 >
133 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
134 >   format for rendering a time zone.
135 >
136 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
137 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
138 >
139 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
140 >    IIBGUIInterface and IIBTimerInf respectively.
141 >
142 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
143 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
144 >
145 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
146 >    truncated to its fixed character width rather than being right padded with
147 >    white space to the maximum data size.
148 >
149 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
150 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
151 >    also empty.
152 >
153 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
154 >
155 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
156 >    connect string. The database name is extracted from the connect string.
157 >
158 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
159 >
160 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
161 >
162 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
163 >    not being present as required.
164 >
165 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
166 >    version that can be customised to work with other database drivers.
167 >
168 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
169 >    unnecessary CR at end of line on Unix platforms.
170 >
171 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
172 >    seconds in order to reduce risk of message loss.
173 >
174 > 23. ISQLMonitor: read and write count statistics now available via:
175 >      property TIBSQLMonitor.ReadCount;
176 >      IIBSQLMonitorHook.GetWriteCount: integer;
177 >
178 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
179 >
180 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
181 >
182 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
183 >    number of UTF8 characters exceeds the string size then string is truncated
184 >    to the maximum string size. This is  usually a problem with fixed width columns
185 >    right padded with white space.
186 >
187 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
188 >    If SQLFiltered is set then when a dataset is opened, each line in the
189 >    SQLFilterParams property is assumed to be a SQL condition clause and
190 >    ANDed into the Where clause of the SQL Select statement provided as a
191 >    dataset property. Each such SQL condition thus acts as an additional filter
192 >    on the dataset.
193 >
194 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
195 >    side filters).
196 >
197 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
198 >   text matches complete entry.
199 >
200 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
201 >   dataset are active (avoids risk of access violation if master is inactive)
202 >
203 > 6. TIBEvents: Registered property can now be set at design time even if database not open
204 >
205 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
206 >   This should prevent "spillover" of events between sessions.
207 >
208 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
209 >   This should ensure that the internal buffer is set up correctly and avoids
210 >   a duplicate initial row.
211 >
212 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
213 >   That is, the DataSize should be the field size * character set width. The
214 >   value returned by DataSize is now the same as the Dataset buffer size reserved
215 >   for the field.
216 >
217 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
218 >
219 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
220 >    and vice-versa. This may result in an exception being raised (correctly) for
221 >    older programs when using dataset fields added to a form and the database has been
222 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
223 >    In such cases, the field needs to be deleted in the IDE fields editor and then
224 >    added back in.
225 >
226 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
227 >    false if query contains only white space and not just empty.
228 >
229 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
230 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
231 >    is cancelled.
232 >
233 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
234 >    called on a null field.
235 >
236 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
237 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
238 > set.
239 >
240 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
241 >    a cached update is applied and an exception is raised.
242 >
243 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
244 >
245 > 17. Console Mode Local Database support: backup/restore should now work correctly.
246 >
247 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
248 >    possible and an exception raised.
249 >
250 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
251 >    below this version no. and upgrade not possible.
252 >
253 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
254 >
255 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
256 >    not SQL Identifiers are now supported.
257 >
258 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
259 >    passed to the Firebird engine for execution.
260 >
261 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
262 >    is made to scroll back.
263 >
264 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
265 >
266 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
267 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
268 >
269 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
270 >   validated. If no match is found in the list of field names and the database has
271 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
272 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
273 >
274 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
275 >   with fpc 3.2.
276 >
277 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
278 >
279 >
280 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
281 >   and is used to override the default settings in the client side "firebird.conf" This
282 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
283 >   Each line of the string list should be a setting in the same format as "firebird.conf".
284 >   For example "WireCompression = true" in order to request wire compression on the client side.
285 >
286 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
287 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
288 >   also require a compatible setting in the server side "firebird.conf". For example
289 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
290 >   compression to be used.
291 >
292 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
293 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
294 >   ibx/examples/dbinfo for examples of how to display this information.
295 >
296 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
297 >   is a "convenience" property. If set the "WireCompression=true" is added to the
298 >   ConfigOverrides. If unchecked then this setting is removed.
299 >
300 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
301 >   not "INT64".
302 >
303 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
304 >   These are:
305 >    property TimestampFormat: string;
306 >    property DateFormat: string;
307 >    property TimeFormat: string;
308 >
309 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
310 >   DATETIME and TIME. The format strings use the standard FPC date/time format
311 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
312 >
313 >   If any of the above properties are set to an empty string, then the locale default
314 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
315 >   locale default is extended by appending '.zzz' to include milliseconds.
316 >
317 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
318 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
319 >
320 > 5. New published property for TIBCSVDataOut:
321 >     property QuoteStrings: boolean (default true)
322 >
323 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
324 >   used to delimit each and every string in the output.
325 >
326 > 6. New published properties for TIBCSVDataOut:
327 >    property FieldSeparator: string;
328 >    property HeaderSeparator: string;
329 >
330 >   Respectively, these provide the separator character(s) used to separate fields
331 >   in data and header rows. Both default to ','.
332 >
333 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
334 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
335 >    property OnFormatTextString;
336 >
337 >   This event handler can be used to process text strings before they are included
338 >   in the output e.g. to replace unprintable characters with alternative strings.
339 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
340 >
341 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
342 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
343 >   and without raising and exception if it does not.
344 >
345 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
346 >   consistency with SQL queries.
347 >
348 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
349 >    When true, SQL statement parameter names are parsed case sensitive. Note for
350 >    TIBDataSet only applies to Select query.
351 >
352 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
353 >    an IDE exception.
354 >
355 > 12. LocalDBSupport: initial database creation should now work correctly
356 >    when the schema source is an sql file.
357 >
358 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
359 >    when defined, this handler will be called by the internal TIBXScript during
360 >    initial database creation when the schema source is an sql file and may be used
361 >    to provide a visual indication of progress in console mode.
362 >
363 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
364 >    to true while a new local database is being created and its schema populated.
365 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
366 >    when the database is disconnected/connected during the create DB procedure.
367 >
368 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
369 >    are now always ignored and replaced by the user name and password provided as
370 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
371 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
372 >    completely ignored if this property is true.
373 >
374 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
375 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
376 >    ImageIndex and SelectImageIndex values on AddNode.
377 >
378 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
379 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
380 >    the same database connection.
381 >
382 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
383 >    if provided, this should be an conditional SQL expression suitable for
384 >    including in an SQL Select statement "where" clause. If non-empty and the
385 >    "Filtered" property is true then the SQL expression provided as the value of
386 >    the "Filter" property is "ANDed" with any existing condition statement
387 >    in the SQL statement's "Where" clause.
388 >
389 >    If the "Filter" property is set at run time, the "Filtered" property is true
390 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
391 >
392 >    The "Filter" condition may include IBX style parameters. In which case, their
393 >    value must be set by the dataset's "OnBeforeOpen" event handler.
394 >
395 >    This is a public property for TIBDataSet and TIBQuery query and intended for
396 >    use at run time.
397 >
398 >    Note: The property is a published property of TIBTable. The TIBTable functionality
399 >    is unaffected by this change.
400 >
401 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
402 >
403 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
404 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
405 >   mode apps.
406 >
407 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
408 >   statement. This avoids problems if "Execute Block" is used as the Query.
409 >
410 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
411 >   internal SQL tokeniser routines.
412 >
413 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
414 >   as a select statement, with or without CTEs.
415 >
416 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
417 >
418 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
419 >   internal SQL tokeniser routines.
420 >
421 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
422 >    being raised for valid set statements processed by a data formatter.
423 >
424 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
425 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
426 >   the path of the Firebird Library used by the database/services connection.
427 >
428 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
429 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/

432 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
433 >   or param name is not a valid SQL identifier.
434 >
435 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
436 >    view of whether the text box should be editable when no DataSource is specified.
437 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
438 >    ReadOnly is false, the text box is editable when no DataSource is specified.
439 >
440 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
441 >    the FBLIB environment variable. If you do not want to permit this then you
442 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
443 >    this setting.

451 >
452 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
453 > all previous copies of the IBX source code tree before installing this release.
454 >
455 > The IBX packages used by most users have not changed, with one exception. The
456 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
457 > to use the IBServices unit in your applications, please add the iblegacyServices
458 > to the list of dependencies. To do this, open the Project Inspector and select
459 > Add->New Requirement and select "ibLegacyServices" from the list of available
460 > packages.
461 >
462 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
463 >   the IBServices unit providing what is intended to be a clearer and easier to
464 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
465 >   more information and the guide to "Firebird Service Management Using IBX".
466 >   As indicated above, the legacy services components are still available and
467 >   provided in a separate package. There is no need to update working applications
468 >   using the older versions except for an additional package dependency.
469 >
470 > 2. The IBX packages and source code tree have been re-organised in an attempt to
471 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
472 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
473 >   new set of IBX packages.
474 >
475 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
476 >   updated to use the new Services API components.
477 >
478 > 4. The iblocal package has been updated to use the new Services API components.
479 >
480 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
481 >   TIBXSecurityService. It had been wrongly classified in the previous version
482 >   as a per database configuration item. It is global to a server and hence
483 >   correctly positioned as part of the Security Package. In the DBAdmin example,
484 >   the setting has moved to the mappings page.
485 >
486 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
487 >   are ignored.
488 >
489 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
490 >   closed before the database is dropped. Before and After Disconnect event handlers
491 >   are also fired.
492 >
493 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
494 >   is started and not just the first time.
495 >
496 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
497 >   depenendency with comp type.
498 >
499 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
500 >
501 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
502 >    then this is recognised and not ignored.
503 >
504 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
505 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
506 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
507 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
508 >
509 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
510 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
511 >    counters for the select query. Note: stats accumulate after each fetch from
512 >    the database. To get total query cost after open, call the "Last" method
513 >    and then GetPerfStatistics.
514 >
515 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
516 >
517 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
518 >    in parenthesises.
519 >
520 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
521 >    SQL identifiers are always delimited by double quotes. If false, then they are
522 >    only delimited if the identifier is a reserved word, contains lower case or special
523 >    characters. Set this property to true to retain previous behaviour.
524 >
525 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
526 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
527 >
528 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
529 >       property MasterDetailDelay: integer {defaults to zero}
530 >
531 >    When non-zero and the dataset is a detail table referencing a master table
532 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
533 >    then a synchronisation delay is added (in milliseconds) between the master
534 >    row changing and the detail dataset being re-opened. If the master dataset
535 >    is scrolled before the delay expires then the delay is reset. This can be used
536 >    to avoid performance overheads when scrolling through a large master dataset.
537 >
538 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
539 >    chreads unit must be included in your project. TTimer is not used in order
540 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
541 >
542 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
543 >    with Extract Option eoDatabase.
544 >
545 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
546 >    When a deLayoutChanged event is reported on the ListSource dataset, the
547 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
548 >    relationship with the control's datasource (master).
549 >
550 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
551 >
552 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
553 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
554 >
555 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
556 >    DDL (Firebird 3 and later only).
557 >
558 > 22. TIBLookupComboBox Autocomplete Fixes:
559 >    i. Only appended text is now selected after autocomplete.
560 >    ii. Uppercase keys no longer ignored for autocomplete.
561 >    iii. Retain Prefix case is now honoured correctly.
562 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
563 >        before autocomplete performed. i.e. behaviour now the same as when
564 >        no DataSource assigned.
565 >
566 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
567 >    between SQL statements.
568 >
569 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
570 >    ObjectNames are converted to upper case before matching against metadata object
571 >    names, unless the objectname is delimited by double quotes, in which case, the
572 >    double quotes are removed and the remaining string is used (unmodified) to match
573 >    against the metadata object name.
574 >
575 >    If true then the ObjectName is used as is without modification and matched
576 >    against the metadata object name. No attempt is made to remove double quotes.
577 >
578 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
579 >    with eoTrigger, these extract types can be used to select only Database Triggers,
580 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
581 >
582 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
583 >    statement separate character is now reset to the default (';').
584 >
585 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
586 >
587 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
588 >    a commit or reconnect statement and instead activated only when next SQL statement
589 >    is executed.
590 >
591 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
592 >
593 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
594 >    converting statement to upper case.
595 >
596 > 31. TIBExtract: metadata comments now supported. New published property
597 >    IncludeMetaDataComments (default true). If true then metadata comments included
598 >    in extracted DDL. New Extract Object member eoComments. This may be used with
599 >    ExtractObject method to list all metadata comments.
600 >
601 > 32. TIBExtract: ListObjectNames method added.
602 >
603 > 33. Updated Database component editor to support additional connection string
604 >    types.
605 >
606 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
607 >
608 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
609 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
610 > RELEASE.
611 >
612 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
613 >
614 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
615 >
616 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
617 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
618 >   information). However, this is also a very useful mechanism for returning updated computed by
619 >   column values. Values returned as a result of executing an Insert or Update statement
620 >   replace existing values in the current row for each corresponding column.
621 >
622 >   Previously, if a dataset's select query included read only (computed by) fields then
623 >   an automatic row refresh was performed after an insert or update query had been processed,
624 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
625 >   that an automatic refresh is no longer performed if an insert or update query contains
626 >   a returning clause that updates one or more fields on the current row. A full row
627 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
628 >   field values and the select query contains read only fields. Use of Insert/update
629 >   returning should be significantly more efficient than executing a refresh query.
630 >
631 >   This behaviour change is intended to be backwards compatible and there should be no need to change
632 >   existing programs, other than to improve performance by using the new capability.
633 >
634 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
635 >   they are called when the dataset row is being deleted, there is no value in
636 >   updating the current record from the query result. Instead, a new event handler
637 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
638 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
639 >   by the query. The event handler can then interrogate the query results and
640 >   perform whatever action is necessary. For example to confirm, to the user,
641 >   the deletion of a row with the returned values.
642 >
643 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
644 >   any Computed By or Identity Columns. The IBTables example has been updated to
645 >   illustrate the computation of the employee Full Name on update.
646 >
647 > 5. TIBTable: The GeneratorField property is now published.
648 >
649 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
650 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
651 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
652 >   each Identity column after the insert is executed.
653 >
654 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
655 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
656 >   Insert..Returning clause.
657 >
658 > 8. TIBGenerator: small performance improvement by not preparing query each time
659 >   a new value is generated.
660 >
661 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
662 >
663 > 10. Property editors will now sync table name to a System Table when "Include System
664 >    Tables" is selected and the query is for a System Table.
665 >
666 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
667 >    values are no longer converted to milliseconds from TDateTime and then back again
668 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
669 >
670 > 12. Property Editors handling of Stored Procedures.
671 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
672 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
673 >      query).
674 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
675 >
676 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
677 >    can be used to select a package. If non-empty, the stored procedure name is
678 >    expected to be a stored procedure defined in the specified package and the
679 >    generated SQL will be as required for a stored procedure located in a package.
680 >
681 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
682 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
683 >    which a stored procedure can be selected. With no package name selected, non-package
684 >    stored procedures are listed.
685 >
686 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
687 >    for password on reconnect.
688 >
689 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
690 >    and character set name.
691 >
692 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
693 >    DB info lookups"
694 >
695 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
696 >
697 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
698 >
699 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
700 >    parameters. This stops an exception being raised when the field cannot be
701 >    located in the record buffer.
702 >
703 > 21. Property Editors now automatically include System Tables when opened and when the query table
704 >    is a System Table.
705 >
706 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
707 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
708 >
709 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
710 >    add the SPB item isc_spb_expected_db. This names a database using
711 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
712 >    database. examples/services re-written to illustrate use of "expected_db".
713 >
714 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
715 >    This avoids truncated backups when the server returns a timeout (busy) response.
716 >
717 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
718 >
719 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
720 >    databasenames. These are respectively expanded to the local system's temp directory
721 >    (including trailing delimiter) or to a prescribed data directory (including
722 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
723 >    in the user's home directory. The hidden directory name is either the string returned
724 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
725 >    Under Windows, the directory is the same as the Data Directory as decribed
726 >    above but instead prefixed by the User's application data path. These may be
727 >    used to improve application portability for Personal Databases.
728 >
729 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
730 >    this has not worked for a long time and is not useful either. FieldDefs should be
731 >    managed using the Fields Editor as with any other dataset. To access the fields
732 >    editor for a TIBTable component, double click on the component. The fields editor
733 >    is then displayed.
734 >
735 > 28. TIBDatabaseInfo: new properties/function
736 >     * DateDBCreated (returns date/time database created)
737 >     * TransactionCount (returns no. of active transactions)
738 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
739 >     * PagesFree (Firebird 3 or later)
740 >     * PagesUsed (Firebird 3 or later)
741 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
742 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
743 >
744 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
745 >
746 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
747 >
748 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
749 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
750 >
751 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
752 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
753 >    firing during backup and restore.
754 >
755 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
756 >    for verbose output using the new property "StatisticsRequested".
757 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
758 >
759 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
760 >
761 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
762 >    palette. This uses the online validation feature added in Firebird 2.5. The
763 >    services's properties enable inclusion/exclusion of tables and indexes using
764 >    regular expressions. See.
765 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
766 >
767 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
768 >    option on a database.
769 >
770 > 37. TIBCustomService: Assign method implemented to allow copying of service login
771 >    context between service API components. "Detach" method now only detaches
772 >    service when last reference to the service interface detaches. Tidy up of
773 >    code for SetActive and Attach methods including password hiding.
774 >
775 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
776 >    and used to determine the auth method and protocol used for the connection.
777 >
778 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
779 >    a Create Database Statement generated by IBX.
780 >
781 > 40. All IBServices now have an additional published property "PortNo". This may
782 >    be set to a non-standard port number when necessary. If zero then the default
783 >    port number is used.
784 >
785 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
786 >    and not just the mouse.
787 >
788 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
789 >
790 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
791 >    image index and selected image index for each node to be set from a database field.
792 >
793 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
794 >    then database schema includes grants to all users. If not present then the
795 >    only user grants included are those to User PUBLIC.
796 >
797 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
798 >    and child nodes in dataset.
799 >
800 >
801 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
802 >
803 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
804 >   changes.
805 >
806 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
807 >   Bug could result in truncated multi-byte character set values.
808 >
809 > 3. Changes consequential on moving fbintf character set utility functions from
810 >   IFirebirdAPI to IAttachment.
811 >
812 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
813 >
814 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
815 >   results in autocomplete ignoring prefix text.
816 >
817 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
818 >   entering a new name into the text box.
819 >
820 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
821 >   Firebird rather than recomputing it.
822 >
823 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
824 >   screen centre. Previously some were "poDesigned" which may be inappropriate
825 >   for multi monitor desktops.
826 >
827 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
828 >
829 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
830 >    a transaction and always reset the object.
831 >
832 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
833 >
834 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
835 >
836 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
837 >    to a gbak format archive.
838 >
839 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
840 >
841 > 16. IBLocaldb: Drop database if error creating an empty database.
842 >
843 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
844 >    unless selected node not in current dataset.
845 >
846 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
847 >    to TIBCustomService, and IBlocalDB code tidy up.
848 >
849 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable

852 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
853 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
854 >
855 > 21. IBSQL: When Database changed ensure that all resources are freed.
856 >
857 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
858 >
859 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
860 >    * Line Wrap on SQL Token boundaries (on user command)
861 >    * auto-complete table names in drop down list of table names
862 >    * Double click on tablename or field name adds to SQL text
863 >
864 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
865 >
866 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
867 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
868 >    workaround for a problem in fpc 3.0.4 win64).
869 >
870 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
871 >
872 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

878 >
879 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
880 >   tables when data included in output.
881 >
882 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
883 >   and timing information to be written to stdout. This may be used to locate

885 >
886 > 4. SQLParser: only call "OnChanging" event handler when value is different.
887 >
888 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
889 >
890 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
891 >   that BindFields is called when the query is next activated. Avoids FieldName
892 >   not found error.
893 >
894 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
895 >   purpose and allows the programmer to define any action they want for Update, Insert
896 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
897 >   filtering of updates, or use of statements such as Grant or Revoke instead of
898 >   normal DML. See User Manual for more information.

902 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
903 >
904 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
905 >
906 > 3. TIBExtract: data formatted as Charset set "octets" is now output using

908 >
909 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
910 >   using a simple XML format.
911 >
912 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
913 >   grants to these objects.
914 >
915 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
916 >   dependency problems restoring complex databases.
917 >
918 > 7. TIBXScript: This component has been restructured to allow for the processing of
919 >   embedded XML in INSERT statements and to support interactive sources in addition
920 >   to non-interactive data sources such as files.
921 >
922 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
923 >
924 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
925 >   SET SQL DIALECT
926 >   SET TERM
927 >   SET AUTODDL
928 >   SET BAIL
929 >   SET ECHO
930 >   SET COUNT
931 >   SET STATS
932 >   SET NAMES <character set>
933 >
934 > 10. IBVersion unit added to hold current IBX Version Number information.
935 >
936 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
937 >    and domain definitions.
938 >
939 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
940 >    fully supported.
941 >
942 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
943 >
944 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

948 > See also doc/IBX4LazarusGuide.pdf for important information on
949 > upgrading to IBX2.
950 >
951 > 1. Size property of TIBStringField is now the width in characters of the field
952 >   and not the byte length. This applies only to multi-byte character sets such
953 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
954 >   code is not recognised as a bug and hence this change to align the behaviour.
955 >   The TStringField change is expected in fpc 3.2.0.
956 >
957 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
958 >   true (default) then Size property value saved in the lfm is ignored. Size is
959 >   always set from the dynamic information read from the database. It is unclear
960 >   why anyone would want to override this and set Size to false.
961 >
962 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
963 >   block.
964 >
965 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
966 >   exist when an attempt is made to connect to it (run time only) then an attempt
967 >   is made to create the database.
968 >
969 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
970 >   has been successfully created as a result of a call to CreateDatabase or when
971 >   creating a database after it was found not to exist.
972 >
973 > 6.  DBControlGrid: a race condition could result in the wrong row image being
974 >    written to the cache. This has been avoided by a trip round the message
975 >    loop before rendering the row image.
976 >
977 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
978 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
979 >    known to risk corrupt rendering of row images when the control is first
980 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
981 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
982 >
983 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
984 >    a TDateEdit control located on an editor panel.
985 >
986 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
987 >
988 > 10. DBControlGrid: Removed memory leak when updating rows.
989 >
990 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

994 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
995 >   when target codepage is CP_NONE. This is a workaround for
996 >   http://bugs.freepascal.org/view.php?id=30622.
997 >
998 > 2. DBLog option removed from TIBStatisticalService - not supported by server
999 >   since Firebird 1.5.
1000 >
1001 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1002 >   similar.
1003 >
1004 > 4. IBCodePage: updated mapping between codepages and character id.
1005 >
1006 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1007 >   Firebird. Character sets with a char width of two are not UTF16.
1008 >
1009 > 6. Strings received from the database are now always transliterated into UTF8
1010 >   regardless of the database character set or connection character set. This

1014 >
1015 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1016 >   read in an entire blob just to get the size of the blob. General performance
1017 >   improvement when opening datasets containing blobs.
1018 >
1019 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
1020 >
1021 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
1022 >   is now used.
1023 >
1024 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1025 >   determined.
1026 >
1027 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1028 >
1029 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1030 >   lazarus 1.6.0

1036 >
1037 > 1. No character set specified for connection: when a text blob is retrieved, the
1038 >  character set is determined by looking up the native character set using then
1039 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
1040 >  set as the connection.
1041 >
1042 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1043 >   for Login Dialog returing a change to the database path.
1044 >
1045 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1046 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
1047 >   entered value to be saved on a project specific basis (design time only).
1048 >
1049 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1050 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
1051 >   Otherwise, it sets the column text to the selected ListField Value.
1052 >
1053 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1054 >   column width.
1055 >
1056 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1057 >   and a case insensitive search is requested.
1058 >
1059 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1060 >   or column ListSource.
1061 >
1062 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1063 >   unprepare) when closing and the text has not changed.
1064 >
1065 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1066 >   Less likely to cause a cursor re-use error on Windows.
1067 >
1068 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1069 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1070 >
1071 > 11. TIBTreeView: Guard against nil destination on record changed
1072 >
1073 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1074 >    string type with the code page set to reflect the returned field encoding after
1075 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1076 >    earlier versions.
1077 >
1078 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1079 >    will now result in transliteration to the code page specified for the Firebird driver
1080 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1081 >
1082 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1083 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
1084 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1085 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1086 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1087 >    the GETACP is used to determine the Windows code page.
1088 >
1089 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1090 >    name used as the lc_ctype when the database was opened. Only valid while the
1091 >    Database is connected.
1092 >
1093 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage

1098 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1099 >   path is given and database attach fails due to access permission issues on the
1100 >   temp directory or security database, then the attach is retried with "localhost:"
1101 >   prefixing the databasename. This should avoid problems when the database has to
1102 >   be accessed by a local (e.g. classic) server and libfbembed is used.
1103 >
1104 > 2. Windows: revised search order for Firebird DLL:
1105 >     i.   The Firebird Embedded Server in the application Directory.
1106 >     ii.  If the FIREBIRD environment variable is set then the directory this
1107 >          points to is searched for the FB Client DLL and then then underlying
1108 >          "bin" directory.
1109 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1110 >          is used to locate the Firebird installation directory and the underlying
1111 >          "bin" directory is searched for the FB Client DLL.
1112 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1113 >          are searched for the FB Client DLL.
1114 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
1115 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1116 >
1117 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1118 >   See doc/readme.scriptengine and example applications.

1122 >   See dpc/readme.localdatabase and example applications.
1123 >
1124 > 5. IBDynamicGrid: Reordering on column header click should now also work for
1125 >   dynamic columns.
1126 >
1127 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1128 >   between incrementing/decrementing the lock count and signalling the event.

1133 >
1134 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1135 >
1136 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1137 >
1138 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1139 >
1140 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1141 >   i.e. when it is a calculated field
1142 >
1143 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1144 >   This problem was due to a race condition between recalculating row heights and
1145 >   determining which row was selected by the mouse click. The row height calculation
1146 >   is now deferred by an extra trip round the message loop allowing the row to
1147 >   be always calculated on the current grid layout rather than risking it being
1148 >   calculated on the grid layout after the expanded row has been shrunk.
1149 >
1150 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1151 >   Windows.
1152 >
1153 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1154 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1155 >   to be determined at runtime. See doc/readme.charactersets.html.
1156 >
1157 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1158 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1159 >
1160 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1161 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1162 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1163 >
1164 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1165 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1166 >   implies no truncation.
1167 >
1168 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1169 >
1170 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1171 >   (avoids "Not in Edit Mode" error).
1172 >
1173 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1174 >
1175 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1176 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1177 >
1178 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1179 >
1180 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1181 >
1182 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1183 >
1184 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

1188 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
1189 >
1190 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids

1192 >
1193 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1194 >

1196 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
1197 >
1198 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1199 >     keyed in i.e. when autocomplete not performed
1200 >
1201 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1202 >     console mode applications with all LCL required functions (builtin dialogs and
1203 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1204 >     not included in your project, IBX should compile and link with a console mode program.
1205 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1206 >     console mode application or the IDE will automatically assume that your
1207 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1208 >
1209 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1210 >     to use the built in dialogs and cursor management. IBDialogs is
1211 >     included by default if "ibexpress" is in your project source's "uses" clause.
1212 >     This should be the case for all projects created through the IDE. This is why
1213 >     you do not want to add the ibexpress package to console mode applications. The
1214 >     ibexpressconsolemode package has been created to allow console mode programs
1215 >     to avoid adding LCL dependencies when using IBX, while still having the
1216 >     unit search paths set up correctly.
1217 >
1218 >     Existing users should check to ensure that the "ibexpress" unit is included in
1219 >     each project's source file (*.lpr).
1220 >
1221 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
1222 >     exists, you have to first open the package in the IDE and then close it. This
1223 >     adds it to the most recently accessed packages list. To make it permanently
1224 >     available, add the package name to lazarus' staticpackages.inc file.
1225 >
1226 >         Thanks to Julio Jiménez for suggesting support of console mode.
1227 >
1228 > 7.   SQL Parser can now accept quoted strings that include new lines
1229 >
1230 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1231 >     of text on start of edit. This is particularly useful when tabbing to a
1232 >     column and then inserting text.
1233 >
1234 > 9.   New Examples provided for IB Services and ISQLMonitor.
1235 >
1236 > 10. Fix error when writing to blob streams that recorded only the last buffer
1237 >    write in the blob stream. In most cases, this did not cause a problem as the
1238 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
1239 >    of a graphic type prefix was lost which caused a problem when the image could
1240 >        not be automatically recognised.
1241 >
1242 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1243 >    already open" errors due to random numbers used for the cursor name being identical.
1244 >
1245 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
1246 >    when opening the table and the Primary Key is the last or only column in the
1247 >    table. Thanks to Rick Hoover for the fix.
1248 >
1249 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead

1258 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1259 >    Link now set up in Loaded method - avoids occasional failure to apply
1260 >    SQL markup on initial open.
1261 >
1262 > 3.  "Employees" example performance improvements when scrolling.
1263 >
1264 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1265 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1266 >    random image cached).
1267 >
1268 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
1269 >
1270 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1271 >    even when further rows exist.
1272 >
1273 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1274 >    always be derived from panel height and setting this property can cause confusion.
1275 >    Note for existing projects: to avoid a missing property error at run time,
1276 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
1277 >    in order to remove the property value from the lfm.

1280 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1281 >
1282 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1283 >    call Prepare before setting parameter values.
1284 >
1285 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1286 >
1287 > 3.  Code tidyup and more robust handling of dsql information result vector.
1288 >
1289 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
1290 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1291 >    and "AfterExecQuery". The first three are called after the same event is called
1292 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1293 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1294 >    enable monitoring of transaction status changes for a given transaction to be
1295 >    handled in a single place. For example, when a change to the dataset occurs
1296 >    an indicator can be set that shows the user that in order to save changes,
1297 >    the transaction should be committed.  Rather than doing this per dataset, this
1298 >    can now be done per transaction.
1299 >
1300 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1301 >    the dataset is scrolled. However, any changes to the current row are, by default,
1302 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1303 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
1304 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
1305 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1306 >    then IBX will attempt to post any unsaved changes before the dataset is closed
1307 >    (and after the BeforeClose event handler is called). The exception is when the
1308 >    dataset is being closed as a result of a transaction rollback. In this case,
1309 >    no action is taken and any unsaved  changes are discarded. This avoids both
1310 >    unnecessary overhead and the risk that a validation error may occur in the Post
1311 >    raising an exception and thereby preventing a rollback.
1312 >
1313 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1314 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1315 >    width. Display Widths are now corrected by dividing by the max byte width per character.
1316 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
1317 >    the byte width divided by 4. The byte width of each character set is determined
1318 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1319 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1320 >
1321 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1322 >
1323 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1324 >    control loses focus. Default Key press default interval reduced to 200ms.
1325 >
1326 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1327 >    when dataset rows are less than visible rows.
1328 >
1329 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1330 >    does not exist or DataSet is empty. More responsive on dataset open. New event
1331 >    OnRestorePosition. Column sort disabled if no header row.
1332 >
1333 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1334 >    while dataset state is dsInsert. Avoids posting errors.
1335 >
1336 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1337 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1338 >
1339 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1340 >
1341 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1342 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1343 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1344 >    always "posts" the current record regardless or whether or not it may be more appropriate
1345 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1346 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1347 >    as the first action of the "Post" method and allows the handler to convert the Post
1348 >    into a Cancel if that is the appropriate action on moving to a different row. This is
1349 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1350 >    raised here, but it may still be more appropriate to validate a post and signal
1351 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1352 >
1353 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
1354 >    separated list. Each library name on the list is tried in turn, in left to right
1355 >    order with the first found being used as the firebird library. By default, on Linux,
1356 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1357 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1358 >
1359 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1360 >    then it will still attempt to access the database via the Firebird Server and will
1361 >    require a username and password. If only the pathname is given, then the username
1362 >    and password should be omitted and the unix file permissions are used to grant
1363 >    access.
1364 >
1365 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1366 >
1367 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1368 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1369 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1370 >    corresponds to a row of the linked DataSource. Any data aware control on the
1371 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1372 >
1373 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1374 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1375 >   takes place during database access. This may be useful when there are performance issues with
1376 >   the change of cursor. Setting the property to false suppresses the change of cursor.
1377 >
1378 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1379 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1380 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1381 >   making all changes permanent immediately rather than when the transaction is explicitly
1382 >   committed.
1383 >
1384 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1385 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1392 >
1393 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1394 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1395 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
1396 >   complexity.
1397 >
1398 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1399 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1400 >   These are:
1401 >
1402 >   - TIBLookupComboEditBox
1403 >   - TIBDynamicGrid
1404 >   - TIBTreeview
1405 >
1406 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1407 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1408 >   to revise the available list and restrict it to items that are prefixed by the
1409 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
1410 >   newly typed entry to be added to the list dataset and included in the available
1411 >   list items.
1412 >
1413 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
1414 >   - automatic resizing of selected columns to fill the available row length
1415 >   - automatic positioning and sizing of a "totals" control, typically at the
1416 >     column footer, on a per column basis.
1417 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
1418 >     A second click on the same header cell reversed the sort order.
1419 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1420 >     is automatically expanded and a panel superimposed on it. The panel can have any
1421 >     number of child controls, typically data aware controls with the same datasource
1422 >     as the grid allowing for editing of additional fields and more complex editors.
1423 >   - Reselection of the same row following resorting.
1424 >   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1425 >     Its properties are specified on a per column basis and allows for one or more
1426 >     columns to have their values selected from a list provided by a dataset.
1427 >     Autocomplete and autoinsert are also available. The existing picklist editor
1428 >     is unaffected by the extension.
1429 >
1430 >   TIBTreeView is a data aware TCustomTreeView.
1431 >
1432 > 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1433 >   zero scale will no longer return an error. An Int64 will be returned instead.
1434 >
1435 > 4. TIBTransaction now has events for Before and After Transaction End and a new function
1436 >   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1437 >
1438 > 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1439 >   repeated multiple times.
1440 >
1441 > 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1442 >   check used to get in the way of using Stored Procedures, and "Update or Insert"
1443 >   statements.
1444 >
1445 > 7. Insert, Modify and Delete property Editors now support Query Generation from
1446 >   Stored Procedures.
1447 >
1448 > 8. Three new examples illustrate the use of the new IB Controls
1449 >
