1 > IBX Change Log  version (2.4-0 Build 12473) Wed, 17 Feb 2021 10:49:57 +0000
2 >
3 > 1. Firebird 4 support added.
4 >
5 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
6 >   extended precision NUMERIC fields are supported.
7 >
8 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
9 >
10 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
11 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
12 >
13 > 5. IBExtract now supports FB4 enhancements:
14 >   - new data types as above
15 >   - Identity column extensions
16 >   - Default user role
17 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
18 >   - Internal Functions
19 >
20 > 6. IBExtract: new event: OnExtractLines.
21 >
22 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
23 >
24 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
25 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
26 >
27 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
28 >   format for rendering a time zone.
29 >
30 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
31 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
32 >
33 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
34 >    IIBGUIInterface and IIBTimerInf respectively.
35 >
36 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
37 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
38 >
39 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
40 >    truncated to its fixed character width rather than being right padded with
41 >    white space to the maximum data size.
42 >
43 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
44 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
45 >    also empty.
46 >
47 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
48 >
49 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
50 >    connect string. The database name is extracted from the connect string.
51 >
52 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
53 >
54 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
55 >
56 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
57 >    not being present as required.
58 >
59 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
60 >    version that can be customised to work with other database drivers.
61 >
62 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
63 >
64 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
65 >    number of UTF8 characters exceeds the string size then string is truncated
66 >    to the maximum string size. This is  usually a problem with fixed width columns
67 >    right padded with white space.
68 >
69 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
70 >    If SQLFiltered is set then when a dataset is opened, each line in the
71 >    SQLFilterParams property is assumed to be a SQL condition clause and
72 >    ANDed into the Where clause of the SQL Select statement provided as a
73 >    dataset property. Each such SQL condition thus acts as an additional filter
74 >    on the dataset.
75 >
76 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
77 >    side filters).
78 >
79 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
80 >   text matches complete entry.
81 >
82 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
83 >   dataset are active (avoids risk of access violation if master is inactive)
84 >
85 > 6. TIBEvents: Registered property can now be set at design time even if database not open
86 >
87 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
88 >   This should prevent "spillover" of events between sessions.
89 >
90 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
91 >   This should ensure that the internal buffer is set up correctly and avoids
92 >   a duplicate initial row.
93 >
94 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
95 >   That is, the DataSize should be the field size * character set width. The
96 >   value returned by DataSize is now the same as the Dataset buffer size reserved
97 >   for the field.
98 >
99 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
100 >
101 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
102 >    and vice-versa. This may result in an exception being raised (correctly) for
103 >    older programs when using dataset fields added to a form and the database has been
104 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
105 >    In such cases, the field needs to be deleted in the IDE fields editor and then
106 >    added back in.
107 >
108 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
109 >    false if query contains only white space and not just empty.
110 >
111 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
112 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
113 >    is cancelled.
114 >
115 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
116 >    called on a null field.
117 >
118 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
119 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
120 > set.
121 >
122 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
123 >    a cached update is applied and an exception is raised.
124 >
125 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
126 >
127 > 17. Console Mode Local Database support: backup/restore should now work correctly.
128 >
129 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
130 >    possible and an exception raised.
131 >
132 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
133 >    below this version no. and upgrade not possible.
134 >
135 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
136 >
137 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
138 >    not SQL Identifiers are now supported.
139 >
140 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
141 >    passed to the Firebird engine for execution.
142 >
143 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
144 >    is made to scroll back.
145 >
146 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
147 >
148 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
149 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
150 >
151 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
152 >   validated. If no match is found in the list of field names and the database has
153 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
154 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
155 >
156 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
157 >   with fpc 3.2.
158 >
159 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
160 >
161 >
162 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
163 >   and is used to override the default settings in the client side "firebird.conf" This
164 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
165 >   Each line of the string list should be a setting in the same format as "firebird.conf".
166 >   For example "WireCompression = true" in order to request wire compression on the client side.
167 >
168 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
169 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
170 >   also require a compatible setting in the server side "firebird.conf". For example
171 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
172 >   compression to be used.
173 >
174 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
175 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
176 >   ibx/examples/dbinfo for examples of how to display this information.
177 >
178 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
179 >   is a "convenience" property. If set the "WireCompression=true" is added to the
180 >   ConfigOverrides. If unchecked then this setting is removed.
181 >
182 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
183 >   not "INT64".
184 >
185 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
186 >   These are:
187 >    property TimestampFormat: string;
188 >    property DateFormat: string;
189 >    property TimeFormat: string;
190 >
191 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
192 >   DATETIME and TIME. The format strings use the standard FPC date/time format
193 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
194 >
195 >   If any of the above properties are set to an empty string, then the locale default
196 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
197 >   locale default is extended by appending '.zzz' to include milliseconds.
198 >
199 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
200 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
201 >
202 > 5. New published property for TIBCSVDataOut:
203 >     property QuoteStrings: boolean (default true)
204 >
205 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
206 >   used to delimit each and every string in the output.
207 >
208 > 6. New published properties for TIBCSVDataOut:
209 >    property FieldSeparator: string;
210 >    property HeaderSeparator: string;
211 >
212 >   Respectively, these provide the separator character(s) used to separate fields
213 >   in data and header rows. Both default to ','.
214 >
215 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
216 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
217 >    property OnFormatTextString;
218 >
219 >   This event handler can be used to process text strings before they are included
220 >   in the output e.g. to replace unprintable characters with alternative strings.
221 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
222 >
223 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
224 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
225 >   and without raising and exception if it does not.
226 >
227 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
228 >   consistency with SQL queries.
229 >
230 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
231 >    When true, SQL statement parameter names are parsed case sensitive. Note for
232 >    TIBDataSet only applies to Select query.
233 >
234 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
235 >    an IDE exception.
236 >
237 > 12. LocalDBSupport: initial database creation should now work correctly
238 >    when the schema source is an sql file.
239 >
240 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
241 >    when defined, this handler will be called by the internal TIBXScript during
242 >    initial database creation when the schema source is an sql file and may be used
243 >    to provide a visual indication of progress in console mode.
244 >
245 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
246 >    to true while a new local database is being created and its schema populated.
247 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
248 >    when the database is disconnected/connected during the create DB procedure.
249 >
250 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
251 >    are now always ignored and replaced by the user name and password provided as
252 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
253 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
254 >    completely ignored if this property is true.
255 >
256 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
257 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
258 >    ImageIndex and SelectImageIndex values on AddNode.
259 >
260 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
261 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
262 >    the same database connection.
263 >
264 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
265 >    if provided, this should be an conditional SQL expression suitable for
266 >    including in an SQL Select statement "where" clause. If non-empty and the
267 >    "Filtered" property is true then the SQL expression provided as the value of
268 >    the "Filter" property is "ANDed" with any existing condition statement
269 >    in the SQL statement's "Where" clause.
270 >
271 >    If the "Filter" property is set at run time, the "Filtered" property is true
272 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
273 >
274 >    The "Filter" condition may include IBX style parameters. In which case, their
275 >    value must be set by the dataset's "OnBeforeOpen" event handler.
276 >
277 >    This is a public property for TIBDataSet and TIBQuery query and intended for
278 >    use at run time.
279 >
280 >    Note: The property is a published property of TIBTable. The TIBTable functionality
281 >    is unaffected by this change.
282 >
283 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
284 >
285 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
286 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
287 >   mode apps.
288 >
289 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
290 >   statement. This avoids problems if "Execute Block" is used as the Query.
291 >
292 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
293 >   internal SQL tokeniser routines.
294 >
295 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
296 >   as a select statement, with or without CTEs.
297 >
298 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
299 >
300 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
301 >   internal SQL tokeniser routines.
302 >
303 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
304 >    being raised for valid set statements processed by a data formatter.
305 >
306 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
307 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
308 >   the path of the Firebird Library used by the database/services connection.
309 >
310 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
311 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
312 >   services connection.
313 >
314 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
315 >   or param name is not a valid SQL identifier.
316 >
317 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
318 >    view of whether the text box should be editable when no DataSource is specified.
319 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
320 >    ReadOnly is false, the text box is editable when no DataSource is specified.
321 >
322 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
323 >    the FBLIB environment variable. If you do not want to permit this then you
324 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
325 >    this setting.
326 >
327 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
328 >
329 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
330 >   Utf8EscapeControlChars
331 >
332 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
333 >
334 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
335 > all previous copies of the IBX source code tree before installing this release.
336 >
337 > The IBX packages used by most users have not changed, with one exception. The
338 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
339 > to use the IBServices unit in your applications, please add the iblegacyServices
340 > to the list of dependencies. To do this, open the Project Inspector and select
341 > Add->New Requirement and select "ibLegacyServices" from the list of available
342 > packages.
343 >
344 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
345 >   the IBServices unit providing what is intended to be a clearer and easier to
346 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
347 >   more information and the guide to "Firebird Service Management Using IBX".
348 >   As indicated above, the legacy services components are still available and
349 >   provided in a separate package. There is no need to update working applications
350 >   using the older versions except for an additional package dependency.
351 >
352 > 2. The IBX packages and source code tree have been re-organised in an attempt to
353 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
354 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
355 >   new set of IBX packages.
356 >
357 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
358 >   updated to use the new Services API components.
359 >
360 > 4. The iblocal package has been updated to use the new Services API components.
361 >
362 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
363 >   TIBXSecurityService. It had been wrongly classified in the previous version
364 >   as a per database configuration item. It is global to a server and hence
365 >   correctly positioned as part of the Security Package. In the DBAdmin example,
366 >   the setting has moved to the mappings page.
367 >
368 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
369 >   are ignored.
370 >
371 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
372 >   closed before the database is dropped. Before and After Disconnect event handlers
373 >   are also fired.
374 >
375 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
376 >   is started and not just the first time.
377 >
378 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
379 >   depenendency with comp type.
380 >
381 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
382 >
383 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
384 >    then this is recognised and not ignored.
385 >
386 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
387 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
388 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
389 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
390 >
391 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
392 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
393 >    counters for the select query. Note: stats accumulate after each fetch from
394 >    the database. To get total query cost after open, call the "Last" method
395 >    and then GetPerfStatistics.
396 >
397 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
398 >
399 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
400 >    in parenthesises.
401 >
402 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
403 >    SQL identifiers are always delimited by double quotes. If false, then they are
404 >    only delimited if the identifier is a reserved word, contains lower case or special
405 >    characters. Set this property to true to retain previous behaviour.
406 >
407 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
408 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
409 >
410 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
411 >       property MasterDetailDelay: integer {defaults to zero}
412 >
413 >    When non-zero and the dataset is a detail table referencing a master table
414 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
415 >    then a synchronisation delay is added (in milliseconds) between the master
416 >    row changing and the detail dataset being re-opened. If the master dataset
417 >    is scrolled before the delay expires then the delay is reset. This can be used
418 >    to avoid performance overheads when scrolling through a large master dataset.
419 >
420 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
421 >    chreads unit must be included in your project. TTimer is not used in order
422 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.

424 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
425 >    with Extract Option eoDatabase.
426 >
427 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
428 >    When a deLayoutChanged event is reported on the ListSource dataset, the
429 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
430 >    relationship with the control's datasource (master).
431 >
432 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
433 >
434 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
435 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
436 >
437 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
438 >    DDL (Firebird 3 and later only).
439 >
440 > 22. TIBLookupComboBox Autocomplete Fixes:
441 >    i. Only appended text is now selected after autocomplete.
442 >    ii. Uppercase keys no longer ignored for autocomplete.
443 >    iii. Retain Prefix case is now honoured correctly.
444 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
445 >        before autocomplete performed. i.e. behaviour now the same as when
446 >        no DataSource assigned.
447 >
448 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
449 >    between SQL statements.
450 >
451 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
452 >    ObjectNames are converted to upper case before matching against metadata object
453 >    names, unless the objectname is delimited by double quotes, in which case, the
454 >    double quotes are removed and the remaining string is used (unmodified) to match
455 >    against the metadata object name.
456 >
457 >    If true then the ObjectName is used as is without modification and matched
458 >    against the metadata object name. No attempt is made to remove double quotes.
459 >
460 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
461 >    with eoTrigger, these extract types can be used to select only Database Triggers,
462 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
463 >
464 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
465 >    statement separate character is now reset to the default (';').
466 >
467 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
468 >
469 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
470 >    a commit or reconnect statement and instead activated only when next SQL statement
471 >    is executed.
472 >
473 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
474 >
475 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
476 >    converting statement to upper case.
477 >
478 > 31. TIBExtract: metadata comments now supported. New published property
479 >    IncludeMetaDataComments (default true). If true then metadata comments included
480 >    in extracted DDL. New Extract Object member eoComments. This may be used with
481 >    ExtractObject method to list all metadata comments.
482 >
483 > 32. TIBExtract: ListObjectNames method added.
484 >
485 > 33. Updated Database component editor to support additional connection string
486 >    types.
