2 >
3 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
4 >
5 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 >   information). However, this is also a very useful mechanism for returning updated computed by
8 >   column values. Values returned as a result of executing an Insert or Update statement
9 >   replace existing values in the current row for each corresponding column.
10 >
11 >   Previously, if a dataset's select query included read only (computed by) fields then
12 >   an automatic row refresh was performed after an insert or update query had been processed,
13 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
14 >   that an automatic refresh is no longer performed if an insert or update query contains
15 >   a returning clause that updates one or more fields on the current row. A full row
16 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17 >   field values and the select query contains read only fields. Use of Insert/update
18 >   returning should be significantly more efficient than executing a refresh query.
19 >
20 >   This behaviour change is intended to be backwards compatible and there should be no need to change
21 >   existing programs, other than to improve performance by using the new capability.
22 >
23 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
24 >   they are called when the dataset row is being deleted, there is no value in
25 >   updating the current record from the query result. Instead, a new event handler
26 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
27 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
28 >   by the query. The event handler can then interrogate the query results and
29 >   perform whatever action is necessary. For example to confirm, to the user,
30 >   the deletion of a row with the returned values.
31 >
32 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
33 >   any Computed By or Identity Columns. The IBTables example has been updated to
34 >   illustrate the computation of the employee Full Name on update.
35 >
36 > 5. TIBTable: The GeneratorField property is now published.
37 >
38 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
39 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
40 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
41 >   each Identity column after the insert is executed.
42 >
43 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
44 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
45 >   Insert..Returning clause.
46 >
47 > 8. TIBGenerator: small performance improvement by not preparing query each time
48 >   a new value is generated.
49 >
50 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
51 >
52 > 10. Property editors will now sync table name to a System Table when "Include System
53 >    Tables" is selected and the query is for a System Table.
54 >
55 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
56 >    values are no longer converted to milliseconds from TDateTime and then back again
57 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
58 >
59 > 12. Property Editors handling of Stored Procedures.
60 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
61 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
62 >      query).
63 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
64 >
65 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
66 >    can be used to select a package. If non-empty, the stored procedure name is
67 >    expected to be a stored procedure defined in the specified package and the
68 >    generated SQL will be as required for a stored procedure located in a package.
69 >
70 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
71 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
72 >    which a stored procedure can be selected. With no package name selected, non-package
73 >    stored procedures are listed.
74 >
75 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
76 >    for password on reconnect.
77 >
78 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
79 >    and character set name.
80 >
81 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
82 >    DB info lookups"
83 >
84 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
85 >
86 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
87 >
88 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
89 >    parameters. This stops an exception being raised when the field cannot be
90 >    located in the record buffer.
91 >
92 > 21. Property Editors now automatically include System Tables when opened and when the query table
93 >    is a System Table.
94 >
95 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws and exception.
96 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
97 >
98 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
99 >    add the SPB item isc_spb_expected_db. This names a database using
100 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
101 >    database. examples/services re-written to illustrate use of "expected_db".
102 >
103 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
104 >    This avoids truncated backups when the server returns a timeout (busy) response.
105 >
106 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
107 >
108 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
109 >    databasenames. These are respectively expanded to the local system's temp directory
110 >    (including trailing delimiter) or to a directory a prescribed data directory (including
111 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
112 >    in the user's home directory. The hidden directory name is either the string returned
113 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
114 >    Under Windows, the directory is the same as the Data Directory as decribed
115 >    above but instead prefixed by the User's application data path. These may be
116 >    used to improve application portability.
117 >
118 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
119 >    this has not worked for a long time and is not useful either. FieldDefs should be
120 >    managed using the Fields Editor as with any other dataset. To access the fields
121 >    editor for a TIBTable component, double click on the component. The fields editor
122 >    is then displayed.
123 >
124 > 28. TIBDatabaseInfo: new properties/function
125 >     * DateDBCreated (returns date/time database created)
126 >     * TransactionCount (returns no. of active transactions)
127 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
128 >     * PagesFree (Firebird 3 or later)
129 >     * PagesUsed (Firebird 3 or later)
130 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
131 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
132 >
133 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
134 >
135 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
136 >
137 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
138 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
139 >
140 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
141 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
142 >    firing during backup and restore.
143 >
144 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
145 >    for verbose output using the new property "StatisticsRequested".
146 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
147 >
148 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
149 >
150 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
151 >    palette. This uses the online validation feature added in Firebird 2.5. The
152 >    services's properties enable inclusion/exclusion of tables and indexes using
153 >    regular expressions. See.
154 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
155 >
156 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
157 >    option on a database.
158 >
159 > 37. TIBCustomService: Assign method implemented to allow copying of service login
160 >    context between service API components. "Detach" method now only detaches
161 >    service when last reference to the service interface detaches. Tidy up of
162 >    code for SetActive and Attach methods including password hiding.
163 >
164 > 38. TIBDatabase: new proterties: AuthenticationMethod and RemoteProtocol. Read only
165 >    and used to determine the auth method and protocol used for the connection.
166 >
167 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
168 >    a Create Database Statement generated by IBX.
169 >
170 > 40. All IBServices now have an additional published property "PortNo". This may
171 >    be set to a non-standard port number when necessary. If zero then the default
172 >    port number is used.
173 >
174 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
175 >    and not just the mouse.
176 >
177 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
178 >
179 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
180 >    image index and selected image index for each node to be set from a database field.
181 >
182 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
183 >    then database schema includes grants to all users. If not present then the
184 >    only user grants included are those to User PUBLIC.
185 >
186 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
187 >    and child nodes in dataset.
188 >
189 >
190 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
191 >
192 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
193 >   changes.
194 >
195 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
196 >   Bug could result in truncated multi-byte character set values.
197 >
198 > 3. Changes consequential on moving fbintf character set utility functions from
199 >   IFirebirdAPI to IAttachment.
200 >
201 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
202 >
203 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
204 >   results in autocomplete ignoring prefix text.
205 >
206 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
207 >   entering a new name into the text box.
208 >
209 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
210 >   Firebird rather than recomputing it.
211 >
212 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
213 >   screen centre. Previously some were "poDesigned" which may be inappropriate
214 >   for multi monitor desktops.
215 >
216 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
217 >
218 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
219 >    a transaction and always reset the object.
220 >
221 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
222 >
223 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
224 >
225 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
226 >    to a gbak format archive.
227 >
228 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
229 >
230 > 16. IBLocaldb: Drop database if error creating an empty database.
231 >
232 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
233 >    unless selected node not in current dataset.
234 >
235 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
236 >    to TIBCustomService, and IBlocalDB code tidy up.
237 >
238 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
239 >    behaviour due to uninitialised variable.
240 >
241 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
242 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
243 >
244 > 21. IBSQL: When Database changed ensure that all resources are freed.
245 >
246 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
247 >
248 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
249 >    * Line Wrap on SQL Token boundaries (on user command)
250 >    * auto-complete table names in drop down list of table names
251 >    * Double click on tablename or field name adds to SQL text
252 >
253 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
254 >
255 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
256 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
257 >    workaround for a problem in fpc 3.0.4 win64).
258 >
259 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
260 >
261 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
262 >
263 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
264 >
265 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
266 >   include remote system name.
267 >
268 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
269 >   tables when data included in output.
270 >
271 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
272 >   and timing information to be written to stdout. This may be used to locate
273 >   performance bottlenecks.
274 >
275 > 4. SQLParser: only call "OnChanging" event handler when value is different.
276 >
277 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
278 >
279 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
280 >   that BindFields is called when the query is next activated. Avoids FieldName
281 >   not found error.
282 >
283 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
284 >   purpose and allows the programmer to define any action they want for Update, Insert
285 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
286 >   filtering of updates, or use of statements such as Grant or Revoke instead of
287 >   normal DML. See User Manual for more information.
288 >
289 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
290 >
291 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
292 >
293 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
294 >
295 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
296 >   hexadecimal notation.
297 >
298 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
299 >   using a simple XML format.
300 >
301 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
302 >   grants to these objects.
303 >
304 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
305 >   dependency problems restoring complex databases.
306 >
307 > 7. TIBXScript: This component has been restructured to allow for the processing of
308 >   embedded XML in INSERT statements and to support interactive sources in addition
309 >   to non-interactive data sources such as files.
310 >
311 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
312 >
313 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
314 >   SET SQL DIALECT
315 >   SET TERM
316 >   SET AUTODDL
317 >   SET BAIL
318 >   SET ECHO
319 >   SET COUNT
320 >   SET STATS
321 >   SET NAMES <character set>
322 >
323 > 10. IBVersion unit added to hold current IBX Version Number information.
324 >
325 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
326 >    and domain definitions.
327 >
328 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
329 >    fully supported.
330 >
331 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
332 >
333 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
334 >
335 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
336 >
337 > See also doc/IBX4LazarusGuide.pdf for important information on
338 > upgrading to IBX2.
339 >
340 > 1. Size property of TIBStringField is now the width in characters of the field
341 >   and not the byte length. This applies only to multi-byte character sets such
342 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
343 >   code is not recognised as a bug and hence this change to align the behaviour.
344 >   The TStringField change is expected in fpc 3.2.0.
345 >
346 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
347 >   true (default) then Size property value saved in the lfm is ignored. Size is
348 >   always set from the dynamic information read from the database. It is unclear
349 >   why anyone would want to override this and set Size to false.
350 >
351 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
352 >   block.
353 >
354 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
355 >   exist when an attempt is made to connect to it (run time only) then an attempt
356 >   is made to create the database.
357 >
358 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
359 >   has been successfully created as a result of a call to CreateDatabase or when
360 >   creating a database after it was found not to exist.
361 >
362 > 6.  DBControlGrid: a race condition could result in the wrong row image being
363 >    written to the cache. This has been avoided by a trip round the message
364 >    loop before rendering the row image.
365 >
366 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
367 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
368 >    known to risk corrupt rendering of row images when the control is first
369 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
370 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
371 >
372 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
373 >    a TDateEdit control located on an editor panel.
374 >
375 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
376 >
377 > 10. DBControlGrid: Removed memory leak when updating rows.
378 >
379 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

382 >
383 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
384 >   when target codepage is CP_NONE. This is a workaround for
385 >   http://bugs.freepascal.org/view.php?id=30622.
386 >
387 > 2. DBLog option removed from TIBStatisticalService - not supported by server
388 >   since Firebird 1.5.
389 >
390 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
391 >   similar.
392 >
393 > 4. IBCodePage: updated mapping between codepages and character id.
394 >
395 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
396 >   Firebird. Character sets with a char width of two are not UTF16.
397 >
398 > 6. Strings received from the database are now always transliterated into UTF8
399 >   regardless of the database character set or connection character set. This
400 >   is for compatibility with the LCL.

402 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
403 >
404 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
405 >   read in an entire blob just to get the size of the blob. General performance
406 >   improvement when opening datasets containing blobs.
407 >
408 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
409 >
410 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
411 >   is now used.
412 >
413 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
414 >   determined.
415 >
416 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
417 >
418 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
419 >   lazarus 1.6.0
420 >
421 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
422 >   compilation error.

439 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
440 >   Otherwise, it sets the column text to the selected ListField Value.

442 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating

445 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given

447 >
448 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
449 >   or column ListSource.
450 >
451 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
452 >   unprepare) when closing and the text has not changed.
453 >
454 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
455 >   Less likely to cause a cursor re-use error on Windows.
456 >
457 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
458 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.

462 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
463 >    string type with the code page set to reflect the returned field encoding after

487 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
488 >   path is given and database attach fails due to access permission issues on the
489 >   temp directory or security database, then the attach is retried with "localhost:"
490 >   prefixing the databasename. This should avoid problems when the database has to
491 >   be accessed by a local (e.g. classic) server and libfbembed is used.

493 > 2. Windows: revised search order for Firebird DLL:
494 >     i.   The Firebird Embedded Server in the application Directory.
495 >     ii.  If the FIREBIRD environment variable is set then the directory this
496 >          points to is searched for the FB Client DLL and then then underlying
497 >          "bin" directory.
498 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
499 >          is used to locate the Firebird installation directory and the underlying
500 >          "bin" directory is searched for the FB Client DLL.

502 >          are searched for the FB Client DLL.
503 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
504 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.

522 >
523 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
524 >
525 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
526 >
527 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early

529 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
530 >   i.e. when it is a calculated field
531 >
532 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
533 >   This problem was due to a race condition between recalculating row heights and
534 >   determining which row was selected by the mouse click. The row height calculation
535 >   is now deferred by an extra trip round the message loop allowing the row to

539 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
540 >   Windows.
541 >
542 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
543 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
544 >   to be determined at runtime. See doc/readme.charactersets.html.

546 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
547 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
548 >
549 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from

556 >
557 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.

597  
598       IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
599       to use the built in dialogs and cursor management. IBDialogs is
600 <     included by default if "ibexpress" is in your project source "uses" clause.
600 >     included by default if "ibexpress" is in your project source's "uses" clause.
601       This should be the case for all projects created through the IDE. This is why
602       you do not want to add the ibexpress package to console mode applications. The
603       ibexpressconsolemode package has been created to allow console mode programs
604       to avoid adding LCL dependencies when using IBX, while still having the
605       unit search paths set up correctly.
606  
607 +     Existing users should check to ensure that the "ibexpress" unit is included in
608 +     each project's source file (*.lpr).
609 +
610       You may find that in order for the IDE to recognise that ibexpressconsolemode
611       exists, you have to first open the package in the IDE and then close it. This
612       adds it to the most recently accessed packages list. To make it permanently
613       available, add the package name to lazarus' staticpackages.inc file.
614  
615 <     Under Windows, the TISQLMonitor OnSQL Event Handler may require a new call to
39 <         Application.ProcessMessages in order to display an event journal correctly. See
40 <         example. This was previously called by TISQLMonitor itself but removed to avoid
41 <         a GUI dependency.

43 <         Thansk to Julio Jiménez for suggesting support of console mode.
615 >         Thanks to Julio Jiménez for suggesting support of console mode.

617   7.   SQL Parser can now accept quoted strings that include new lines

630  
631   11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
632 <    already open" errors due to random numbers being identical.
632 >    already open" errors due to random numbers used for the cursor name being identical.
633  
634   12. IBTable: corrected error that could result in an "Index out of bounds" error
635      when opening the table and the Primary Key is the last or only column in the
636      table. Thanks to Rick Hoover for the fix.

638 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
639 >    of "UTF-8", and update list of available database character sets. Existing

757      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
# Line 197 | Line 773 | IBX Change Log  version
773   4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
