1 < IBX Change Log  version                                                              (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1 > IBX Change Log  version (2.4-3 Build 12803) Wed, 06 Oct 2021 10:20:04 +0100
2 >
3 > 1. Add try-..except check when initially loading library in IDE. This should
4 > ensure that IDE continues to load even when a failure occurs in IBX load
5 > library.
6 >
7 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 >   hence will correctly detect end of the outer containing block when the block
9 >   contains a SELECT ... CASE ... END construct.
10 >
11 > 3. IBExtract: some further tidying up to remove extraneous white space.
12 >
13 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
14 >
15 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
16 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
17 >
18 > 2. TIBSQL: Batch Update/Insert support added.
19 >
20 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
21 >   is no longer automatically converted to upper case when it is syntactically a
22 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
23 >   as CREATE PROCEDURE "iCASE".
24 >
25 >   There could be a backwards compatibility issue when the StoredProcName was entered
26 >   manually at design time. That is not selected from the drop down list. If the
27 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
28 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
29 >   ensure that the value of the StoredProcName is all upper case, unless it was
30 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
31 >   quotes).
32 >
33 >   Note that when a stored procedure name was declared delimited in double quotes,
34 >   as in the first example above, the value of the StoredProcName property must not
35 >   include the delimiters (double quotes).
36 >
37 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
38 >   upgrade.conf was not found. This replaces silently ignoring the problem.
39 >
40 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
41 >   'Version.%.3d' and is used to generate the section header names (for a given
42 >   version no.) in the upgrade.conf file.
43 >
44 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
45 >
46 > 1. -c command line option added to fbsql example program. Used to set connection
47 >   character set.
48 >
49 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
50 >
51 > 1. Firebird 4 support added.
52 >
53 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
54 >   extended precision NUMERIC fields are supported.
55 >
56 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
57 >
58 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
59 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
60 >
61 > 5. IBExtract now supports FB4 enhancements:
62 >   - new data types as above
63 >   - Identity column extensions
64 >   - Default user role
65 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
66 >   - Internal Functions
67 >
68 > 6. IBExtract: new event: OnExtractLines.
69 >
70 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
71 >
72 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
73 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
74 >
75 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
76 >   format for rendering a time zone.
77 >
78 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
79 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
80 >
81 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
82 >    IIBGUIInterface and IIBTimerInf respectively.
83 >
84 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
85 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
86 >
87 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
88 >    truncated to its fixed character width rather than being right padded with
89 >    white space to the maximum data size.
90 >
91 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
92 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
93 >    also empty.
94 >
95 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
96 >
97 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
98 >    connect string. The database name is extracted from the connect string.
99 >
100 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
101 >
102 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
103 >
104 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
105 >    not being present as required.
106 >
107 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
108 >    version that can be customised to work with other database drivers.
109 >
110 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
111 >    unnecessary CR at end of line on Unix platforms.
112 >
113 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
114 >    seconds in order to reduce risk of message loss.
115 >
116 > 23. ISQLMonitor: read and write count statistics now available via:
117 >      property TIBSQLMonitor.ReadCount;
118 >      IIBSQLMonitorHook.GetWriteCount: integer;
119 >
120 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
121 >
122 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
123 >
124 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
125 >    number of UTF8 characters exceeds the string size then string is truncated
126 >    to the maximum string size. This is  usually a problem with fixed width columns
127 >    right padded with white space.
128 >
129 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
130 >    If SQLFiltered is set then when a dataset is opened, each line in the
131 >    SQLFilterParams property is assumed to be a SQL condition clause and
132 >    ANDed into the Where clause of the SQL Select statement provided as a
133 >    dataset property. Each such SQL condition thus acts as an additional filter
134 >    on the dataset.
135 >
136 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
137 >    side filters).
138 >
139 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
140 >   text matches complete entry.
141 >
142 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
143 >   dataset are active (avoids risk of access violation if master is inactive)
144 >
145 > 6. TIBEvents: Registered property can now be set at design time even if database not open
146 >
147 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
148 >   This should prevent "spillover" of events between sessions.
149 >
150 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
151 >   This should ensure that the internal buffer is set up correctly and avoids
152 >   a duplicate initial row.
153 >
154 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
155 >   That is, the DataSize should be the field size * character set width. The
156 >   value returned by DataSize is now the same as the Dataset buffer size reserved
157 >   for the field.
158 >
159 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
160 >
161 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
162 >    and vice-versa. This may result in an exception being raised (correctly) for
163 >    older programs when using dataset fields added to a form and the database has been
164 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
165 >    In such cases, the field needs to be deleted in the IDE fields editor and then
166 >    added back in.
167 >
168 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
169 >    false if query contains only white space and not just empty.
170 >
171 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
172 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
173 >    is cancelled.
174 >
175 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
176 >    called on a null field.
177 >
178 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
179 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
180 > set.
181 >
182 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
183 >    a cached update is applied and an exception is raised.
184 >
185 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
186 >
187 > 17. Console Mode Local Database support: backup/restore should now work correctly.
188 >
189 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
190 >    possible and an exception raised.
191 >
192 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
193 >    below this version no. and upgrade not possible.
194 >
195 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
196 >
197 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
198 >    not SQL Identifiers are now supported.
199 >
200 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
201 >    passed to the Firebird engine for execution.
202 >
203 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
204 >    is made to scroll back.
205 >
206 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
207 >
208 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
209 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
210 >
211 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
212 >   validated. If no match is found in the list of field names and the database has
213 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
214 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
215 >
216 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
217 >   with fpc 3.2.
218 >
219 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
220 >
221 >
222 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
223 >   and is used to override the default settings in the client side "firebird.conf" This
224 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
225 >   Each line of the string list should be a setting in the same format as "firebird.conf".
226 >   For example "WireCompression = true" in order to request wire compression on the client side.
227 >
228 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
229 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
230 >   also require a compatible setting in the server side "firebird.conf". For example
231 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
232 >   compression to be used.
233 >
234 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
235 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
236 >   ibx/examples/dbinfo for examples of how to display this information.
237 >
238 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
239 >   is a "convenience" property. If set the "WireCompression=true" is added to the
240 >   ConfigOverrides. If unchecked then this setting is removed.
241 >
242 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
243 >   not "INT64".
244 >
245 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
246 >   These are:
247 >    property TimestampFormat: string;
248 >    property DateFormat: string;
249 >    property TimeFormat: string;
250 >
251 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
252 >   DATETIME and TIME. The format strings use the standard FPC date/time format
253 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
254 >
255 >   If any of the above properties are set to an empty string, then the locale default
256 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
257 >   locale default is extended by appending '.zzz' to include milliseconds.
258 >
259 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
260 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
261 >
262 > 5. New published property for TIBCSVDataOut:
263 >     property QuoteStrings: boolean (default true)
264 >
265 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
266 >   used to delimit each and every string in the output.
267 >
268 > 6. New published properties for TIBCSVDataOut:
269 >    property FieldSeparator: string;
270 >    property HeaderSeparator: string;
271 >
272 >   Respectively, these provide the separator character(s) used to separate fields
273 >   in data and header rows. Both default to ','.
274 >
275 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
276 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
277 >    property OnFormatTextString;
278 >
279 >   This event handler can be used to process text strings before they are included
280 >   in the output e.g. to replace unprintable characters with alternative strings.
281 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
282 >
283 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
284 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
285 >   and without raising and exception if it does not.
286 >
287 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
288 >   consistency with SQL queries.
289 >
290 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
291 >    When true, SQL statement parameter names are parsed case sensitive. Note for
292 >    TIBDataSet only applies to Select query.
293 >
294 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
295 >    an IDE exception.
296 >
297 > 12. LocalDBSupport: initial database creation should now work correctly
298 >    when the schema source is an sql file.
299 >
300 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
301 >    when defined, this handler will be called by the internal TIBXScript during
302 >    initial database creation when the schema source is an sql file and may be used
303 >    to provide a visual indication of progress in console mode.
304 >
305 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
306 >    to true while a new local database is being created and its schema populated.
307 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
308 >    when the database is disconnected/connected during the create DB procedure.
309 >
310 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
311 >    are now always ignored and replaced by the user name and password provided as
312 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
313 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
314 >    completely ignored if this property is true.
315 >
316 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
317 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
318 >    ImageIndex and SelectImageIndex values on AddNode.
319 >
320 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
321 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
322 >    the same database connection.
323 >
324 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
325 >    if provided, this should be an conditional SQL expression suitable for
326 >    including in an SQL Select statement "where" clause. If non-empty and the
327 >    "Filtered" property is true then the SQL expression provided as the value of
328 >    the "Filter" property is "ANDed" with any existing condition statement
329 >    in the SQL statement's "Where" clause.
330 >
331 >    If the "Filter" property is set at run time, the "Filtered" property is true
332 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
333 >
334 >    The "Filter" condition may include IBX style parameters. In which case, their
335 >    value must be set by the dataset's "OnBeforeOpen" event handler.
336 >
337 >    This is a public property for TIBDataSet and TIBQuery query and intended for
338 >    use at run time.
339 >
340 >    Note: The property is a published property of TIBTable. The TIBTable functionality
341 >    is unaffected by this change.
342 >
343 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
344 >
345 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
346 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
347 >   mode apps.
348 >
349 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
350 >   statement. This avoids problems if "Execute Block" is used as the Query.
351 >
352 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
353 >   internal SQL tokeniser routines.
354 >
355 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
356 >   as a select statement, with or without CTEs.
357 >
358 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
359 >
360 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
361 >   internal SQL tokeniser routines.
362 >
363 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
364 >    being raised for valid set statements processed by a data formatter.
365 >
366 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
367 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
368 >   the path of the Firebird Library used by the database/services connection.
369 >
370 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
371 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
372 >   services connection.
373 >
374 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
375 >   or param name is not a valid SQL identifier.
376 >
377 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
378 >    view of whether the text box should be editable when no DataSource is specified.
379 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
380 >    ReadOnly is false, the text box is editable when no DataSource is specified.
381 >
382 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
383 >    the FBLIB environment variable. If you do not want to permit this then you
384 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
385 >    this setting.

394 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
395 > all previous copies of the IBX source code tree before installing this release.
396 >
397 > The IBX packages used by most users have not changed, with one exception. The
398 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
399 > to use the IBServices unit in your applications, please add the iblegacyServices
400 > to the list of dependencies. To do this, open the Project Inspector and select
401 > Add->New Requirement and select "ibLegacyServices" from the list of available
402 > packages.
403 >
404 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
405 >   the IBServices unit providing what is intended to be a clearer and easier to
406 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
407 >   more information and the guide to "Firebird Service Management Using IBX".
408 >   As indicated above, the legacy services components are still available and
409 >   provided in a separate package. There is no need to update working applications
410 >   using the older versions except for an additional package dependency.
411 >
412 > 2. The IBX packages and source code tree have been re-organised in an attempt to
413 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
414 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
415 >   new set of IBX packages.
416 >
417 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
418 >   updated to use the new Services API components.
419 >
420 > 4. The iblocal package has been updated to use the new Services API components.

422 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
423 >   TIBXSecurityService. It had been wrongly classified in the previous version
424 >   as a per database configuration item. It is global to a server and hence
425 >   correctly positioned as part of the Security Package. In the DBAdmin example,
426 >   the setting has moved to the mappings page.
427 >
428 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
429 >   are ignored.
430 >
431 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
432 >   closed before the database is dropped. Before and After Disconnect event handlers
433 >   are also fired.
434 >
435 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
436 >   is started and not just the first time.
437 >
438 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
439 >   depenendency with comp type.
440 >
441 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
442 >
443 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
444 >    then this is recognised and not ignored.
445 >
446 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
447 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
448 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
449 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
450 >
451 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
452 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
453 >    counters for the select query. Note: stats accumulate after each fetch from
454 >    the database. To get total query cost after open, call the "Last" method
455 >    and then GetPerfStatistics.
456 >
457 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
458 >
459 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
460 >    in parenthesises.
461 >
462 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
463 >    SQL identifiers are always delimited by double quotes. If false, then they are
464 >    only delimited if the identifier is a reserved word, contains lower case or special
465 >    characters. Set this property to true to retain previous behaviour.
466 >
467 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
468 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
469 >
470 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
471 >       property MasterDetailDelay: integer {defaults to zero}
472 >
473 >    When non-zero and the dataset is a detail table referencing a master table
474 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
475 >    then a synchronisation delay is added (in milliseconds) between the master
476 >    row changing and the detail dataset being re-opened. If the master dataset
477 >    is scrolled before the delay expires then the delay is reset. This can be used
478 >    to avoid performance overheads when scrolling through a large master dataset.
479 >
480 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
481 >    chreads unit must be included in your project. TTimer is not used in order
482 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
483 >
484 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
485 >    with Extract Option eoDatabase.
486 >
487 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
488 >    When a deLayoutChanged event is reported on the ListSource dataset, the
489 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
490 >    relationship with the control's datasource (master).
491 >
492 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
493 >
494 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
495 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
496 >
497 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
498 >    DDL (Firebird 3 and later only).
499 >
500 > 22. TIBLookupComboBox Autocomplete Fixes:
501 >    i. Only appended text is now selected after autocomplete.
502 >    ii. Uppercase keys no longer ignored for autocomplete.
503 >    iii. Retain Prefix case is now honoured correctly.
504 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
505 >        before autocomplete performed. i.e. behaviour now the same as when
506 >        no DataSource assigned.
507 >
508 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
509 >    between SQL statements.
510 >
511 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
512 >    ObjectNames are converted to upper case before matching against metadata object
513 >    names, unless the objectname is delimited by double quotes, in which case, the
514 >    double quotes are removed and the remaining string is used (unmodified) to match
515 >    against the metadata object name.
516 >
517 >    If true then the ObjectName is used as is without modification and matched
518 >    against the metadata object name. No attempt is made to remove double quotes.
519 >
520 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
521 >    with eoTrigger, these extract types can be used to select only Database Triggers,
522 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
523 >
524 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
525 >    statement separate character is now reset to the default (';').
526 >
527 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
528 >
529 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
530 >    a commit or reconnect statement and instead activated only when next SQL statement
531 >    is executed.
532 >
533 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
534 >
535 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
536 >    converting statement to upper case.
537 >
538 > 31. TIBExtract: metadata comments now supported. New published property
539 >    IncludeMetaDataComments (default true). If true then metadata comments included
540 >    in extracted DDL. New Extract Object member eoComments. This may be used with
541 >    ExtractObject method to list all metadata comments.
542 >
543 > 32. TIBExtract: ListObjectNames method added.
544 >
545 > 33. Updated Database component editor to support additional connection string
546 >    types.
547 >
548 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
549 >
550 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
551 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
552 > RELEASE.
553 >
554 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
555 >
556 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
557 >
558 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
559 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
560 >   information). However, this is also a very useful mechanism for returning updated computed by
561 >   column values. Values returned as a result of executing an Insert or Update statement
562 >   replace existing values in the current row for each corresponding column.
563 >
564 >   Previously, if a dataset's select query included read only (computed by) fields then
565 >   an automatic row refresh was performed after an insert or update query had been processed,
566 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
567 >   that an automatic refresh is no longer performed if an insert or update query contains
568 >   a returning clause that updates one or more fields on the current row. A full row
569 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
570 >   field values and the select query contains read only fields. Use of Insert/update
571 >   returning should be significantly more efficient than executing a refresh query.
572 >
573 >   This behaviour change is intended to be backwards compatible and there should be no need to change
574 >   existing programs, other than to improve performance by using the new capability.
575 >
576 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
577 >   they are called when the dataset row is being deleted, there is no value in
578 >   updating the current record from the query result. Instead, a new event handler
579 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
580 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
581 >   by the query. The event handler can then interrogate the query results and
582 >   perform whatever action is necessary. For example to confirm, to the user,
583 >   the deletion of a row with the returned values.
584 >
585 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
586 >   any Computed By or Identity Columns. The IBTables example has been updated to
587 >   illustrate the computation of the employee Full Name on update.
588 >
589 > 5. TIBTable: The GeneratorField property is now published.
590 >
591 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
592 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
593 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
594 >   each Identity column after the insert is executed.
595 >
596 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
597 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
598 >   Insert..Returning clause.
599 >
600 > 8. TIBGenerator: small performance improvement by not preparing query each time
601 >   a new value is generated.
602 >
603 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
604 >
605 > 10. Property editors will now sync table name to a System Table when "Include System
606 >    Tables" is selected and the query is for a System Table.
607 >
608 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
609 >    values are no longer converted to milliseconds from TDateTime and then back again
610 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
611 >
612 > 12. Property Editors handling of Stored Procedures.
613 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
614 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
615 >      query).
616 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
617 >
618 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
619 >    can be used to select a package. If non-empty, the stored procedure name is
620 >    expected to be a stored procedure defined in the specified package and the
621 >    generated SQL will be as required for a stored procedure located in a package.
622 >
623 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
624 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
625 >    which a stored procedure can be selected. With no package name selected, non-package
626 >    stored procedures are listed.
627 >
628 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
629 >    for password on reconnect.
630 >
631 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
632 >    and character set name.
633 >
634 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
635 >    DB info lookups"
636 >
637 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
638 >
639 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
640 >
641 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
642 >    parameters. This stops an exception being raised when the field cannot be
643 >    located in the record buffer.
644 >
645 > 21. Property Editors now automatically include System Tables when opened and when the query table
646 >    is a System Table.
647 >
648 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
649 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
650 >
651 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
652 >    add the SPB item isc_spb_expected_db. This names a database using
653 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
654 >    database. examples/services re-written to illustrate use of "expected_db".
655 >
656 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
657 >    This avoids truncated backups when the server returns a timeout (busy) response.
658 >
659 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
660 >
661 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
662 >    databasenames. These are respectively expanded to the local system's temp directory
663 >    (including trailing delimiter) or to a prescribed data directory (including
664 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
665 >    in the user's home directory. The hidden directory name is either the string returned
666 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
667 >    Under Windows, the directory is the same as the Data Directory as decribed
668 >    above but instead prefixed by the User's application data path. These may be
669 >    used to improve application portability for Personal Databases.
670 >
671 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
672 >    this has not worked for a long time and is not useful either. FieldDefs should be
673 >    managed using the Fields Editor as with any other dataset. To access the fields
674 >    editor for a TIBTable component, double click on the component. The fields editor
675 >    is then displayed.
676 >
677 > 28. TIBDatabaseInfo: new properties/function
678 >     * DateDBCreated (returns date/time database created)
679 >     * TransactionCount (returns no. of active transactions)
680 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
681 >     * PagesFree (Firebird 3 or later)
682 >     * PagesUsed (Firebird 3 or later)
683 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
684 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
685 >
686 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
687 >
688 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
689 >
690 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
691 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
692 >
693 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
694 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
695 >    firing during backup and restore.
696 >
697 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
698 >    for verbose output using the new property "StatisticsRequested".
699 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
700 >
701 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
702 >
703 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
704 >    palette. This uses the online validation feature added in Firebird 2.5. The
705 >    services's properties enable inclusion/exclusion of tables and indexes using
706 >    regular expressions. See.
707 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
708 >
709 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
710 >    option on a database.
711 >
712 > 37. TIBCustomService: Assign method implemented to allow copying of service login
713 >    context between service API components. "Detach" method now only detaches
714 >    service when last reference to the service interface detaches. Tidy up of
715 >    code for SetActive and Attach methods including password hiding.
716 >
717 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
718 >    and used to determine the auth method and protocol used for the connection.
719 >
720 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
721 >    a Create Database Statement generated by IBX.
722 >
723 > 40. All IBServices now have an additional published property "PortNo". This may
724 >    be set to a non-standard port number when necessary. If zero then the default
725 >    port number is used.
726 >
727 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
728 >    and not just the mouse.
729 >
730 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
731 >
732 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
733 >    image index and selected image index for each node to be set from a database field.
734 >
735 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
736 >    then database schema includes grants to all users. If not present then the
737 >    only user grants included are those to User PUBLIC.
738 >
739 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
740 >    and child nodes in dataset.
741 >
742 >
743 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
744 >
745 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
746 >   changes.
747 >
748 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
749 >   Bug could result in truncated multi-byte character set values.
750 >
751 > 3. Changes consequential on moving fbintf character set utility functions from
752 >   IFirebirdAPI to IAttachment.
753 >
754 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
755 >
756 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
757 >   results in autocomplete ignoring prefix text.
758 >
759 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
760 >   entering a new name into the text box.
761 >
762 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
763 >   Firebird rather than recomputing it.
764 >
765 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
766 >   screen centre. Previously some were "poDesigned" which may be inappropriate
767 >   for multi monitor desktops.
768 >
769 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
770 >
771 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
772 >    a transaction and always reset the object.
773 >
774 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
775 >
776 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
777 >
778 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
779 >    to a gbak format archive.
780 >
781 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
782 >
783 > 16. IBLocaldb: Drop database if error creating an empty database.
784 >
785 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
786 >    unless selected node not in current dataset.
787 >
788 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
789 >    to TIBCustomService, and IBlocalDB code tidy up.
790 >
791 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
792 >    behaviour due to uninitialised variable.
793 >
794 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
795 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
796 >
797 > 21. IBSQL: When Database changed ensure that all resources are freed.
798 >
799 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
800 >
801 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
802 >    * Line Wrap on SQL Token boundaries (on user command)
803 >    * auto-complete table names in drop down list of table names
804 >    * Double click on tablename or field name adds to SQL text
805 >
806 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
807 >
808 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
809 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
810 >    workaround for a problem in fpc 3.0.4 win64).
811 >
812 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
813 >
814 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
815 >
816 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
817 >
818 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
819 >   include remote system name.
820 >
821 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
822 >   tables when data included in output.
823 >
824 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
825 >   and timing information to be written to stdout. This may be used to locate
826 >   performance bottlenecks.
827 >
828 > 4. SQLParser: only call "OnChanging" event handler when value is different.
829 >
830 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
831 >
832 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
833 >   that BindFields is called when the query is next activated. Avoids FieldName
834 >   not found error.
835 >
836 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
837 >   purpose and allows the programmer to define any action they want for Update, Insert
838 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
839 >   filtering of updates, or use of statements such as Grant or Revoke instead of
840 >   normal DML. See User Manual for more information.
841 >
842 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
843 >

890 > See also doc/IBX4LazarusGuide.pdf for important information on
891 > upgrading to IBX2.
892 >
893 > 1. Size property of TIBStringField is now the width in characters of the field
894 >   and not the byte length. This applies only to multi-byte character sets such
895 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
896 >   code is not recognised as a bug and hence this change to align the behaviour.
897 >   The TStringField change is expected in fpc 3.2.0.
898 >
899 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
900 >   true (default) then Size property value saved in the lfm is ignored. Size is
901 >   always set from the dynamic information read from the database. It is unclear
902 >   why anyone would want to override this and set Size to false.
903 >
904 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
905 >   block.
906 >
907 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
908 >   exist when an attempt is made to connect to it (run time only) then an attempt
909 >   is made to create the database.
910 >
911 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
912 >   has been successfully created as a result of a call to CreateDatabase or when
913 >   creating a database after it was found not to exist.
914 >
915 > 6.  DBControlGrid: a race condition could result in the wrong row image being
916 >    written to the cache. This has been avoided by a trip round the message
917 >    loop before rendering the row image.
918 >
919 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
920 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
921 >    known to risk corrupt rendering of row images when the control is first
922 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
923 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
924 >
925 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
926 >    a TDateEdit control located on an editor panel.
927 >
928 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
929 >
930 > 10. DBControlGrid: Removed memory leak when updating rows.

944 >   similar.
945 >
946 > 4. IBCodePage: updated mapping between codepages and character id.
947 >
948 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
949 >   Firebird. Character sets with a char width of two are not UTF16.
950 >
951 > 6. Strings received from the database are now always transliterated into UTF8

960 >
961 > 2. Clearing a  Blob now sets the corresponding field's modified flag.

978 >
979 > 1. No character set specified for connection: when a text blob is retrieved, the
980 >  character set is determined by looking up the native character set using then
981 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
982 >  set as the connection.

984 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
985 >   for Login Dialog returing a change to the database path.
986 >
987 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
988 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
989 >   entered value to be saved on a project specific basis (design time only).
990 >
991 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
992 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
993 >   Otherwise, it sets the column text to the selected ListField Value.
994 >
995 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
996 >   column width.
997 >
998 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
999 >   and a case insensitive search is requested.
1000 >
1001 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1002 >   or column ListSource.
1003 >
1004 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1005 >   unprepare) when closing and the text has not changed.
1006 >
1007 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1008 >   Less likely to cause a cursor re-use error on Windows.
1009 >
1010 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1011 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1012 >
1013 > 11. TIBTreeView: Guard against nil destination on record changed
1014 >
1015 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1016 >    string type with the code page set to reflect the returned field encoding after
1017 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1018 >    earlier versions.
1019 >
1020 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1021 >    will now result in transliteration to the code page specified for the Firebird driver
1022 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1023 >
1024 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1025 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
1026 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1027 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1028 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1029 >    the GETACP is used to determine the Windows code page.
1030 >
1031 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1032 >    name used as the lc_ctype when the database was opened. Only valid while the
1033 >    Database is connected.
1034 >
1035 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage

1040 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1041 >   path is given and database attach fails due to access permission issues on the
1042 >   temp directory or security database, then the attach is retried with "localhost:"

1044 >   be accessed by a local (e.g. classic) server and libfbembed is used.
1045 >
1046 > 2. Windows: revised search order for Firebird DLL:
1047 >     i.   The Firebird Embedded Server in the application Directory.
1048 >     ii.  If the FIREBIRD environment variable is set then the directory this
1049 >          points to is searched for the FB Client DLL and then then underlying
1050 >          "bin" directory.
1051 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1052 >          is used to locate the Firebird installation directory and the underlying
1053 >          "bin" directory is searched for the FB Client DLL.
1054 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1055 >          are searched for the FB Client DLL.
1056 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
1057 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.

1075 >
1076 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1077 >
1078 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1079 >
1080 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1081 >
1082 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1083 >   i.e. when it is a calculated field
1084 >
1085 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1086 >   This problem was due to a race condition between recalculating row heights and
1087 >   determining which row was selected by the mouse click. The row height calculation
1088 >   is now deferred by an extra trip round the message loop allowing the row to
1089 >   be always calculated on the current grid layout rather than risking it being
1090 >   calculated on the grid layout after the expanded row has been shrunk.
1091 >
1092 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1093 >   Windows.
1094 >
1095 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1096 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1097 >   to be determined at runtime. See doc/readme.charactersets.html.
1098 >
1099 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1100 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1101 >
1102 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1103 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1104 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1105 >
1106 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1107 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1108 >   implies no truncation.
1109 >
1110 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1111 >
1112 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1113 >   (avoids "Not in Edit Mode" error).
1114 >
1115 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1116 >
1117 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1118 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1119 >
1120 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1121 >
1122 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1123 >
1124 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1125 >
1126 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

1130 > 1.   OnCloseUp Event Handler added to TDBLookupProperties

1134 >
1135 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1136 >

1140 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1141 >     keyed in i.e. when autocomplete not performed
1142 >
1143 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1144 >     console mode applications with all LCL required functions (builtin dialogs and
1145 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1146 >     not included in your project, IBX should compile and link with a console mode program.
1147 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1148 >     console mode application or the IDE will automatically assume that your
1149 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1150 >
1151 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1152 >     to use the built in dialogs and cursor management. IBDialogs is
1153 >     included by default if "ibexpress" is in your project source's "uses" clause.
1154 >     This should be the case for all projects created through the IDE. This is why
1155 >     you do not want to add the ibexpress package to console mode applications. The
1156 >     ibexpressconsolemode package has been created to allow console mode programs
1157 >     to avoid adding LCL dependencies when using IBX, while still having the
1158 >     unit search paths set up correctly.
1159 >
1160 >     Existing users should check to ensure that the "ibexpress" unit is included in
1161 >     each project's source file (*.lpr).
1162 >
1163 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
1164 >     exists, you have to first open the package in the IDE and then close it. This
1165 >     adds it to the most recently accessed packages list. To make it permanently
1166 >     available, add the package name to lazarus' staticpackages.inc file.
1167 >
1168 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
1169 >
1170 > 7.   SQL Parser can now accept quoted strings that include new lines
1171 >
1172 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1173 >     of text on start of edit. This is particularly useful when tabbing to a
1174 >     column and then inserting text.
1175 >
1176 > 9.   New Examples provided for IB Services and ISQLMonitor.
1177 >
1178 > 10. Fix error when writing to blob streams that recorded only the last buffer
1179 >    write in the blob stream. In most cases, this did not cause a problem as the
1180 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
1181 >    of a graphic type prefix was lost which caused a problem when the image could
1182 >        not be automatically recognised.
1183 >
1184 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1185 >    already open" errors due to random numbers used for the cursor name being identical.
1186 >
1187 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
1188 >    when opening the table and the Primary Key is the last or only column in the
1189 >    table. Thanks to Rick Hoover for the fix.
1190 >
1191 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
