7 >
8 > 1. Firebird 4 support added.
9 >
10 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
11 >   extended precision NUMERIC fields are supported.
12 >
13 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
14 >
15 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
16 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
17 >
18 > 5. IBExtract now supports FB4 enhancements:
19 >   - new data types as above
20 >   - Identity column extensions
21 >   - Default user role
22 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
23 >   - Internal Functions
24 >
25 > 6. IBExtract: new event: OnExtractLines.
26 >
27 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
28 >
29 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
30 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
31 >
32 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
33 >   format for rendering a time zone.
34 >
35 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
36 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
37 >
38 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
39 >    IIBGUIInterface and IIBTimerInf respectively.
40 >
41 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
42 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
43 >
44 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
45 >    truncated to its fixed character width rather than being right padded with
46 >    white space to the maximum data size.
47 >
48 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
49 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
50 >    also empty.
51 >
52 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
53 >
54 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
55 >    connect string. The database name is extracted from the connect string.
56 >
57 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
58 >
59 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
60 >
61 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
62 >    not being present as required.
63 >
64 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
65 >    version that can be customised to work with other database drivers.
66 >
67 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
68 >    unnecessary CR at end of line on Unix platforms.
69 >
70 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
71 >    seconds in order to reduce risk of message loss.
72 >
73 > 23. ISQLMonitor: read and write count statistics now available via:
74 >      property TIBSQLMonitor.ReadCount;
75 >      IIBSQLMonitorHook.GetWriteCount: integer;
76 >
77 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
78 >
79 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
80 >
81 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
82 >    number of UTF8 characters exceeds the string size then string is truncated
83 >    to the maximum string size. This is  usually a problem with fixed width columns
84 >    right padded with white space.
85 >
86 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
87 >    If SQLFiltered is set then when a dataset is opened, each line in the
88 >    SQLFilterParams property is assumed to be a SQL condition clause and
89 >    ANDed into the Where clause of the SQL Select statement provided as a
90 >    dataset property. Each such SQL condition thus acts as an additional filter
91 >    on the dataset.
92 >
93 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
94 >    side filters).
95 >
96 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
97 >   text matches complete entry.
98 >
99 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
100 >   dataset are active (avoids risk of access violation if master is inactive)
101 >
102 > 6. TIBEvents: Registered property can now be set at design time even if database not open
103 >
104 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
105 >   This should prevent "spillover" of events between sessions.
106 >
107 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
108 >   This should ensure that the internal buffer is set up correctly and avoids
109 >   a duplicate initial row.
110 >
111 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
112 >   That is, the DataSize should be the field size * character set width. The
113 >   value returned by DataSize is now the same as the Dataset buffer size reserved
114 >   for the field.
115 >
116 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
117 >
118 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
119 >    and vice-versa. This may result in an exception being raised (correctly) for
120 >    older programs when using dataset fields added to a form and the database has been
121 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
122 >    In such cases, the field needs to be deleted in the IDE fields editor and then
123 >    added back in.
124 >
125 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
126 >    false if query contains only white space and not just empty.
127 >
128 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
129 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
130 >    is cancelled.
131 >
132 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
133 >    called on a null field.
134 >
135 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
136 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
137 > set.
138 >
139 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
140 >    a cached update is applied and an exception is raised.
141 >
142 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
143 >
144 > 17. Console Mode Local Database support: backup/restore should now work correctly.
145 >
146 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
147 >    possible and an exception raised.
148 >
149 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
150 >    below this version no. and upgrade not possible.
151 >
152 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
153 >
154 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
155 >    not SQL Identifiers are now supported.
156 >
157 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
158 >    passed to the Firebird engine for execution.
159 >
160 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
161 >    is made to scroll back.
162 >
163 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
164 >
165 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
166 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
167 >
168 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
169 >   validated. If no match is found in the list of field names and the database has
170 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
171 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
172 >
173 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
174 >   with fpc 3.2.
175 >
176 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
177 >
178 >
179 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
180 >   and is used to override the default settings in the client side "firebird.conf" This
181 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
182 >   Each line of the string list should be a setting in the same format as "firebird.conf".
183 >   For example "WireCompression = true" in order to request wire compression on the client side.
184 >
185 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
186 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
187 >   also require a compatible setting in the server side "firebird.conf". For example
188 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
189 >   compression to be used.
190 >
191 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
192 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
193 >   ibx/examples/dbinfo for examples of how to display this information.
194 >
195 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
196 >   is a "convenience" property. If set the "WireCompression=true" is added to the
197 >   ConfigOverrides. If unchecked then this setting is removed.
198 >
199 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
200 >   not "INT64".
201 >
202 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
203 >   These are:
204 >    property TimestampFormat: string;
205 >    property DateFormat: string;
206 >    property TimeFormat: string;
207 >
208 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
209 >   DATETIME and TIME. The format strings use the standard FPC date/time format
210 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
211 >
212 >   If any of the above properties are set to an empty string, then the locale default
213 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
214 >   locale default is extended by appending '.zzz' to include milliseconds.
215 >
216 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
217 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
218 >
219 > 5. New published property for TIBCSVDataOut:
220 >     property QuoteStrings: boolean (default true)
221 >
222 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
223 >   used to delimit each and every string in the output.
224 >
225 > 6. New published properties for TIBCSVDataOut:
226 >    property FieldSeparator: string;
227 >    property HeaderSeparator: string;
228 >
229 >   Respectively, these provide the separator character(s) used to separate fields
230 >   in data and header rows. Both default to ','.
231 >
232 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
233 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
234 >    property OnFormatTextString;
235 >
236 >   This event handler can be used to process text strings before they are included
237 >   in the output e.g. to replace unprintable characters with alternative strings.
238 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
239 >
240 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
241 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
242 >   and without raising and exception if it does not.
243 >
244 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
245 >   consistency with SQL queries.
246 >
247 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
248 >    When true, SQL statement parameter names are parsed case sensitive. Note for
249 >    TIBDataSet only applies to Select query.
250 >
251 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
252 >    an IDE exception.
253 >
254 > 12. LocalDBSupport: initial database creation should now work correctly
255 >    when the schema source is an sql file.
256 >
257 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
258 >    when defined, this handler will be called by the internal TIBXScript during
259 >    initial database creation when the schema source is an sql file and may be used
260 >    to provide a visual indication of progress in console mode.
261 >
262 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
263 >    to true while a new local database is being created and its schema populated.
264 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
265 >    when the database is disconnected/connected during the create DB procedure.
266 >
267 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
268 >    are now always ignored and replaced by the user name and password provided as
269 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
270 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
271 >    completely ignored if this property is true.
272 >
273 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
274 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
275 >    ImageIndex and SelectImageIndex values on AddNode.
276 >
277 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
278 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
279 >    the same database connection.
280 >
281 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
282 >    if provided, this should be an conditional SQL expression suitable for
283 >    including in an SQL Select statement "where" clause. If non-empty and the
284 >    "Filtered" property is true then the SQL expression provided as the value of
285 >    the "Filter" property is "ANDed" with any existing condition statement
286 >    in the SQL statement's "Where" clause.
287 >
288 >    If the "Filter" property is set at run time, the "Filtered" property is true
289 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
290 >
291 >    The "Filter" condition may include IBX style parameters. In which case, their
292 >    value must be set by the dataset's "OnBeforeOpen" event handler.
293 >
294 >    This is a public property for TIBDataSet and TIBQuery query and intended for
295 >    use at run time.
296 >
297 >    Note: The property is a published property of TIBTable. The TIBTable functionality
298 >    is unaffected by this change.
299 >
300 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
301 >
302 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
303 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
304 >   mode apps.
305 >
306 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
307 >   statement. This avoids problems if "Execute Block" is used as the Query.
308 >
309 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
310 >   internal SQL tokeniser routines.
311 >
312 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
313 >   as a select statement, with or without CTEs.
314 >
315 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
316 >
317 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
318 >   internal SQL tokeniser routines.
319 >
320 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
321 >    being raised for valid set statements processed by a data formatter.
322 >
323 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
324 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
325 >   the path of the Firebird Library used by the database/services connection.
326 >
327 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
328 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
329 >   services connection.
330 >
331 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
332 >   or param name is not a valid SQL identifier.
333 >
334 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
335 >    view of whether the text box should be editable when no DataSource is specified.
336 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
337 >    ReadOnly is false, the text box is editable when no DataSource is specified.
338 >
339 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
340 >    the FBLIB environment variable. If you do not want to permit this then you
341 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
342 >    this setting.
343 >
344 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
345 >
346 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
347 >   Utf8EscapeControlChars
348 >
349 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
350 >
351 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
352 > all previous copies of the IBX source code tree before installing this release.
353 >
354 > The IBX packages used by most users have not changed, with one exception. The
355 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
356 > to use the IBServices unit in your applications, please add the iblegacyServices
357 > to the list of dependencies. To do this, open the Project Inspector and select
358 > Add->New Requirement and select "ibLegacyServices" from the list of available
359 > packages.
360 >
361 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
362 >   the IBServices unit providing what is intended to be a clearer and easier to
363 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
364 >   more information and the guide to "Firebird Service Management Using IBX".
365 >   As indicated above, the legacy services components are still available and
366 >   provided in a separate package. There is no need to update working applications
367 >   using the older versions except for an additional package dependency.
368 >
369 > 2. The IBX packages and source code tree have been re-organised in an attempt to
370 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
371 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
372 >   new set of IBX packages.
373 >
374 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
375 >   updated to use the new Services API components.
376 >
377 > 4. The iblocal package has been updated to use the new Services API components.
378 >
379 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
380 >   TIBXSecurityService. It had been wrongly classified in the previous version
381 >   as a per database configuration item. It is global to a server and hence
382 >   correctly positioned as part of the Security Package. In the DBAdmin example,
383 >   the setting has moved to the mappings page.
384 >
385 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
386 >   are ignored.
387 >
388 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
389 >   closed before the database is dropped. Before and After Disconnect event handlers
390 >   are also fired.
391 >
392 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
393 >   is started and not just the first time.
394 >
395 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
396 >   depenendency with comp type.
397 >
398 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
399 >
400 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
401 >    then this is recognised and not ignored.
402 >
403 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
404 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
405 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
406 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
407 >
408 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
409 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
410 >    counters for the select query. Note: stats accumulate after each fetch from
411 >    the database. To get total query cost after open, call the "Last" method
412 >    and then GetPerfStatistics.
413 >
414 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
415 >
416 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
417 >    in parenthesises.
418 >
419 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
420 >    SQL identifiers are always delimited by double quotes. If false, then they are
421 >    only delimited if the identifier is a reserved word, contains lower case or special
422 >    characters. Set this property to true to retain previous behaviour.
423 >
424 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
425 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
426 >
427 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
428 >       property MasterDetailDelay: integer {defaults to zero}
429 >
430 >    When non-zero and the dataset is a detail table referencing a master table
431 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
432 >    then a synchronisation delay is added (in milliseconds) between the master
433 >    row changing and the detail dataset being re-opened. If the master dataset
434 >    is scrolled before the delay expires then the delay is reset. This can be used
435 >    to avoid performance overheads when scrolling through a large master dataset.
436 >
437 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
438 >    chreads unit must be included in your project. TTimer is not used in order
439 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
440 >
441 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
442 >    with Extract Option eoDatabase.
443 >
444 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
445 >    When a deLayoutChanged event is reported on the ListSource dataset, the
446 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
447 >    relationship with the control's datasource (master).
448 >
449 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
450 >
451 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
452 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
453 >
454 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
455 >    DDL (Firebird 3 and later only).
456 >
457 > 22. TIBLookupComboBox Autocomplete Fixes:
458 >    i. Only appended text is now selected after autocomplete.
459 >    ii. Uppercase keys no longer ignored for autocomplete.
460 >    iii. Retain Prefix case is now honoured correctly.
461 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
462 >        before autocomplete performed. i.e. behaviour now the same as when
463 >        no DataSource assigned.
464 >
465 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
466 >    between SQL statements.
467 >
468 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
469 >    ObjectNames are converted to upper case before matching against metadata object
470 >    names, unless the objectname is delimited by double quotes, in which case, the
471 >    double quotes are removed and the remaining string is used (unmodified) to match
472 >    against the metadata object name.
473 >
474 >    If true then the ObjectName is used as is without modification and matched
475 >    against the metadata object name. No attempt is made to remove double quotes.
476 >
477 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
478 >    with eoTrigger, these extract types can be used to select only Database Triggers,
479 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
480 >
481 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
482 >    statement separate character is now reset to the default (';').
483 >
484 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
485 >
486 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
487 >    a commit or reconnect statement and instead activated only when next SQL statement
488 >    is executed.
489 >
490 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
491 >
492 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
493 >    converting statement to upper case.
494 >
495 > 31. TIBExtract: metadata comments now supported. New published property
496 >    IncludeMetaDataComments (default true). If true then metadata comments included
497 >    in extracted DDL. New Extract Object member eoComments. This may be used with
498 >    ExtractObject method to list all metadata comments.
499 >
500 > 32. TIBExtract: ListObjectNames method added.
501 >
502 > 33. Updated Database component editor to support additional connection string
503 >    types.
504 >
505 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
506 >
507 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
508 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
509 > RELEASE.
510 >
511 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
512 >
513 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
514 >
515 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
516 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
517 >   information). However, this is also a very useful mechanism for returning updated computed by
518 >   column values. Values returned as a result of executing an Insert or Update statement
519 >   replace existing values in the current row for each corresponding column.
520 >
521 >   Previously, if a dataset's select query included read only (computed by) fields then
522 >   an automatic row refresh was performed after an insert or update query had been processed,
523 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
524 >   that an automatic refresh is no longer performed if an insert or update query contains
525 >   a returning clause that updates one or more fields on the current row. A full row
526 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
527 >   field values and the select query contains read only fields. Use of Insert/update
528 >   returning should be significantly more efficient than executing a refresh query.
529 >
530 >   This behaviour change is intended to be backwards compatible and there should be no need to change
531 >   existing programs, other than to improve performance by using the new capability.
532 >
533 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
534 >   they are called when the dataset row is being deleted, there is no value in
535 >   updating the current record from the query result. Instead, a new event handler
536 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
537 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
538 >   by the query. The event handler can then interrogate the query results and
539 >   perform whatever action is necessary. For example to confirm, to the user,
540 >   the deletion of a row with the returned values.
541 >
542 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
543 >   any Computed By or Identity Columns. The IBTables example has been updated to
544 >   illustrate the computation of the employee Full Name on update.
545 >
546 > 5. TIBTable: The GeneratorField property is now published.
547 >
548 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
549 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
550 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
551 >   each Identity column after the insert is executed.
552 >
553 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
554 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
555 >   Insert..Returning clause.
556 >
557 > 8. TIBGenerator: small performance improvement by not preparing query each time
558 >   a new value is generated.
559 >
560 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
561 >
562 > 10. Property editors will now sync table name to a System Table when "Include System
563 >    Tables" is selected and the query is for a System Table.
564 >
565 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
566 >    values are no longer converted to milliseconds from TDateTime and then back again
567 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
568 >
569 > 12. Property Editors handling of Stored Procedures.
570 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
571 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
572 >      query).
573 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
574 >
575 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
576 >    can be used to select a package. If non-empty, the stored procedure name is
577 >    expected to be a stored procedure defined in the specified package and the
578 >    generated SQL will be as required for a stored procedure located in a package.
579 >
580 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
581 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
582 >    which a stored procedure can be selected. With no package name selected, non-package
583 >    stored procedures are listed.
584 >
585 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
586 >    for password on reconnect.
587 >
588 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
589 >    and character set name.
590 >
591 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
592 >    DB info lookups"
593 >
594 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
595 >
596 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
597 >
598 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
599 >    parameters. This stops an exception being raised when the field cannot be
600 >    located in the record buffer.
601 >
602 > 21. Property Editors now automatically include System Tables when opened and when the query table
603 >    is a System Table.
604 >
605 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
606 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
607 >
608 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
609 >    add the SPB item isc_spb_expected_db. This names a database using
610 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
611 >    database. examples/services re-written to illustrate use of "expected_db".
612 >
613 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
614 >    This avoids truncated backups when the server returns a timeout (busy) response.
615 >
616 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
617 >
618 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
619 >    databasenames. These are respectively expanded to the local system's temp directory
620 >    (including trailing delimiter) or to a prescribed data directory (including
621 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
622 >    in the user's home directory. The hidden directory name is either the string returned
623 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
624 >    Under Windows, the directory is the same as the Data Directory as decribed
625 >    above but instead prefixed by the User's application data path. These may be
626 >    used to improve application portability for Personal Databases.
627 >
628 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
629 >    this has not worked for a long time and is not useful either. FieldDefs should be
630 >    managed using the Fields Editor as with any other dataset. To access the fields
631 >    editor for a TIBTable component, double click on the component. The fields editor
632 >    is then displayed.
633 >
634 > 28. TIBDatabaseInfo: new properties/function
635 >     * DateDBCreated (returns date/time database created)
636 >     * TransactionCount (returns no. of active transactions)
637 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
638 >     * PagesFree (Firebird 3 or later)
639 >     * PagesUsed (Firebird 3 or later)
640 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
641 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
642 >
643 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
644 >
645 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
646 >
647 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
648 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
649 >
650 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
651 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
652 >    firing during backup and restore.
653 >
654 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
655 >    for verbose output using the new property "StatisticsRequested".
656 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
657 >
658 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
659 >
660 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
661 >    palette. This uses the online validation feature added in Firebird 2.5. The
662 >    services's properties enable inclusion/exclusion of tables and indexes using
663 >    regular expressions. See.
664 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
665 >
666 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
667 >    option on a database.
668 >
669 > 37. TIBCustomService: Assign method implemented to allow copying of service login
670 >    context between service API components. "Detach" method now only detaches
671 >    service when last reference to the service interface detaches. Tidy up of
672 >    code for SetActive and Attach methods including password hiding.
673 >
674 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
675 >    and used to determine the auth method and protocol used for the connection.
676 >
677 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
678 >    a Create Database Statement generated by IBX.
679 >
680 > 40. All IBServices now have an additional published property "PortNo". This may
681 >    be set to a non-standard port number when necessary. If zero then the default
682 >    port number is used.
683 >
684 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
685 >    and not just the mouse.
686 >
687 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
688 >
689 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
690 >    image index and selected image index for each node to be set from a database field.
691 >
692 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
693 >    then database schema includes grants to all users. If not present then the
694 >    only user grants included are those to User PUBLIC.
695 >
696 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
697 >    and child nodes in dataset.
698 >
699 >
