38 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
39 >   using a simple XML format.
40 >
41 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
42 >   grants to these objects.
43 >
44 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
45 >   dependency problems restoring complex databases.
46 >
47 > 7. TIBXScript: This component has been restructured to allow for the processing of
48 >   embedded XML in INSERT statements and to support interactive sources in addition
49 >   to non-interactive data sources such as files.
50 >
51 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
52 >
53 > 9. TIBXScript: ISQL compatiable Set statements are now supported:

61 >   SET NAMES <character set>
62 >
63 > 10. IBVersion unit added to hold current IBX Version Number information.
64 >
65 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
66 >    and domain definitions.
67 >
68 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
69 >    fully supported.
70 >
71 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
72 >
73 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
74 >
75 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
76 >
77 > See also doc/IBX4LazarusGuide.pdf for important information on
78 > upgrading to IBX2.
79 >
80 > 1. Size property of TIBStringField is now the width in characters of the field
81 >   and not the byte length. This applies only to multi-byte character sets such
82 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
83 >   code is not recognised as a bug and hence this change to align the behaviour.
84 >   The TStringField change is expected in fpc 3.2.0.
85 >
86 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
87 >   true (default) then Size property value saved in the lfm is ignored. Size is
88 >   always set from the dynamic information read from the database. It is unclear
89 >   why anyone would want to override this and set Size to false.
90 >
91 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
92 >   block.
93 >
94 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
95 >   exist when an attempt is made to connect to it (run time only) then an attempt
96 >   is made to create the database.
97 >
98 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
99 >   has been successfully created as a result of a call to CreateDatabase or when
100 >   creating a database after it was found not to exist.
101 >
102 > 6.  DBControlGrid: a race condition could result in the wrong row image being
103 >    written to the cache. This has been avoided by a trip round the message
104 >    loop before rendering the row image.
105 >
106 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
107 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
108 >    known to risk corrupt rendering of row images when the control is first
109 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
110 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
111 >
112 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
113 >    a TDateEdit control located on an editor panel.
114 >
115 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
116 >
117 > 10. DBControlGrid: Removed memory leak when updating rows.
118 >
119 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
120 >
121 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
122 >
123 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
124 >   when target codepage is CP_NONE. This is a workaround for
125 >   http://bugs.freepascal.org/view.php?id=30622.
126 >
127 > 2. DBLog option removed from TIBStatisticalService - not supported by server
128 >   since Firebird 1.5.
129 >
130 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
131 >   similar.
132 >
133 > 4. IBCodePage: updated mapping between codepages and character id.
134 >
135 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
136 >   Firebird. Character sets with a char width of two are not UTF16.
137 >
138 > 6. Strings received from the database are now always transliterated into UTF8
139 >   regardless of the database character set or connection character set. This
140 >   is for compatibility with the LCL.
141 >
142 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
143 >
144 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
145 >   read in an entire blob just to get the size of the blob. General performance
146 >   improvement when opening datasets containing blobs.
147 >
148 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
149 >
150 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
151 >   is now used.
152 >
153 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
154 >   determined.
155 >
156 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
157 >
158 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
159 >   lazarus 1.6.0
160 >
161 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
162 >   compilation error.
163 >
164 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
165 >
166 > 1. No character set specified for connection: when a text blob is retrieved, the
167 >  character set is determined by looking up the native character set using then
168 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
169 >  set as the connection.
170 >
171 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
172 >   for Login Dialog returing a change to the database path.
173 >
174 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
175 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
176 >   entered value to be saved on a project specific basis (design time only).
177 >
178 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
179 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
180 >   Otherwise, it sets the column text to the selected ListField Value.
181 >
182 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
183 >   column width.
184 >
185 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
186 >   and a case insensitive search is requested.
187 >
188 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
189 >   or column ListSource.
190 >
191 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
192 >   unprepare) when closing and the text has not changed.
193 >
194 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
195 >   Less likely to cause a cursor re-use error on Windows.
196 >
197 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
198 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
199 >
200 > 11. TIBTreeView: Guard against nil destination on record changed
201 >
202 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
203 >    string type with the code page set to reflect the returned field encoding after
204 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
205 >    earlier versions.
206 >
207 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
208 >    will now result in transliteration to the code page specified for the Firebird driver
209 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
210 >
211 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
212 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
213 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
214 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
215 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
216 >    the GETACP is used to determine the Windows code page.
217 >
218 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
219 >    name used as the lc_ctype when the database was opened. Only valid while the
220 >    Database is connected.
221 >
222 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
223 >    id that corresponds to the DefaultCharSetName.
224 >
225 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
226 >
227 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
228 >   path is given and database attach fails due to access permission issues on the
229 >   temp directory or security database, then the attach is retried with "localhost:"
230 >   prefixing the databasename. This should avoid problems when the database has to
231 >   be accessed by a local (e.g. classic) server and libfbembed is used.
232 >
233 > 2. Windows: revised search order for Firebird DLL:
234 >     i.   The Firebird Embedded Server in the application Directory.
235 >     ii.  If the FIREBIRD environment variable is set then the directory this
236 >          points to is searched for the FB Client DLL and then then underlying
237 >          "bin" directory.
238 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
239 >          is used to locate the Firebird installation directory and the underlying
240 >          "bin" directory is searched for the FB Client DLL.
241 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
242 >          are searched for the FB Client DLL.
243 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
244 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
245 >
246 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
247 >   See doc/readme.scriptengine and example applications.
248 >
249 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
250 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
251 >   See dpc/readme.localdatabase and example applications.
252 >
253 > 5. IBDynamicGrid: Reordering on column header click should now also work for
254 >   dynamic columns.
255 >
256 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
257 >   between incrementing/decrementing the lock count and signalling the event.
258 >
259 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
260 >
261 > 1.3.2 was never formally released and only made available as beta copies.
262 >
263 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
264 >
265 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
266 >
267 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
268 >
269 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
270 >   i.e. when it is a calculated field
271 >
272 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
273 >   This problem was due to a race condition between recalculating row heights and
274 >   determining which row was selected by the mouse click. The row height calculation
275 >   is now deferred by an extra trip round the message loop allowing the row to
276 >   be always calculated on the current grid layout rather than risking it being
277 >   calculated on the grid layout after the expanded row has been shrunk.
278 >
279 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
280 >   Windows.
281 >
282 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
283 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
284 >   to be determined at runtime. See doc/readme.charactersets.html.
285 >
286 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
287 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
288 >
289 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
290 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
291 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
292 >
293 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
294 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
295 >   implies no truncation.
296 >
297 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
298 >
299 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
300 >   (avoids "Not in Edit Mode" error).
301 >
302 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
303 >
304 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
305 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
306 >
307 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
308 >
309 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
310 >
311 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
312 >
313 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
314 >
315 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
316 >
317 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
318 >
319 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
320 >     problem with row size when exception is called.
321 >
322 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
323 >
324 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
325 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
326 >
327 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
328 >     keyed in i.e. when autocomplete not performed
329 >
330 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
331 >     console mode applications with all LCL required functions (builtin dialogs and
332 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
333 >     not included in your project, IBX should compile and link with a console mode program.
334 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
335 >     console mode application or the IDE will automatically assume that your
336 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
337 >
338 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
339 >     to use the built in dialogs and cursor management. IBDialogs is
340 >     included by default if "ibexpress" is in your project source's "uses" clause.
341 >     This should be the case for all projects created through the IDE. This is why
342 >     you do not want to add the ibexpress package to console mode applications. The
343 >     ibexpressconsolemode package has been created to allow console mode programs
344 >     to avoid adding LCL dependencies when using IBX, while still having the
345 >     unit search paths set up correctly.
346 >
347 >     Existing users should check to ensure that the "ibexpress" unit is included in
348 >     each project's source file (*.lpr).
349 >
350 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
351 >     exists, you have to first open the package in the IDE and then close it. This
352 >     adds it to the most recently accessed packages list. To make it permanently
353 >     available, add the package name to lazarus' staticpackages.inc file.
354 >
355 >         Thanks to Julio Jiménez for suggesting support of console mode.
356 >
357 > 7.   SQL Parser can now accept quoted strings that include new lines
358 >
359 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
360 >     of text on start of edit. This is particularly useful when tabbing to a
361 >     column and then inserting text.
362 >
363 > 9.   New Examples provided for IB Services and ISQLMonitor.
364 >
365 > 10. Fix error when writing to blob streams that recorded only the last buffer
366 >    write in the blob stream. In most cases, this did not cause a problem as the
367 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
368 >    of a graphic type prefix was lost which caused a problem when the image could
369 >        not be automatically recognised.
370 >
371 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
372 >    already open" errors due to random numbers used for the cursor name being identical.
373 >
374 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
375 >    when opening the table and the Primary Key is the last or only column in the
376 >    table. Thanks to Rick Hoover for the fix.
377 >
378 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
379 >    of "UTF-8", and update list of available database character sets. Existing
380 >    users should check the current lc_ctype setting in their applications.
381 >
382 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
383 >
384 > 1.  Firebird Services: avoid List Index error when opening a service with an
385 >    empty Params property.
386 >
387 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
388 >    Link now set up in Loaded method - avoids occasional failure to apply
389 >    SQL markup on initial open.
390 >
391 > 3.  "Employees" example performance improvements when scrolling.
392 >
393 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
394 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
395 >    random image cached).
396 >
397 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
398 >
399 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
400 >    even when further rows exist.
401 >
402 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
403 >    always be derived from panel height and setting this property can cause confusion.
404 >    Note for existing projects: to avoid a missing property error at run time,
405 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
406 >    in order to remove the property value from the lfm.
407 >
408 >
409 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
410 >
411 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
412 >    call Prepare before setting parameter values.
413 >
414 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
415 >
416 > 3.  Code tidyup and more robust handling of dsql information result vector.
417 >
418 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
419 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
420 >    and "AfterExecQuery". The first three are called after the same event is called
421 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
422 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
423 >    enable monitoring of transaction status changes for a given transaction to be
424 >    handled in a single place. For example, when a change to the dataset occurs
425 >    an indicator can be set that shows the user that in order to save changes,
426 >    the transaction should be committed.  Rather than doing this per dataset, this
427 >    can now be done per transaction.
428 >
429 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
430 >    the dataset is scrolled. However, any changes to the current row are, by default,
431 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
432 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
433 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
434 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
435 >    then IBX will attempt to post any unsaved changes before the dataset is closed
436 >    (and after the BeforeClose event handler is called). The exception is when the
437 >    dataset is being closed as a result of a transaction rollback. In this case,
438 >    no action is taken and any unsaved  changes are discarded. This avoids both
439 >    unnecessary overhead and the risk that a validation error may occur in the Post
440 >    raising an exception and thereby preventing a rollback.
441 >
442 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
443 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
444 >    width. Display Widths are now corrected by dividing by the max byte width per character.
445 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
446 >    the byte width divided by 4. The byte width of each character set is determined
447 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
448 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
449 >
450 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
451 >
452 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
453 >    control loses focus. Default Key press default interval reduced to 200ms.
454 >
455 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
456 >    when dataset rows are less than visible rows.
457 >
458 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
459 >    does not exist or DataSet is empty. More responsive on dataset open. New event
460 >    OnRestorePosition. Column sort disabled if no header row.
461 >
462 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
463 >    while dataset state is dsInsert. Avoids posting errors.
464 >
465 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
466 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
467 >
468 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
469 >
470 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
471 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
472 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
473 >    always "posts" the current record regardless or whether or not it may be more appropriate
474 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
475 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
476 >    as the first action of the "Post" method and allows the handler to convert the Post
477 >    into a Cancel if that is the appropriate action on moving to a different row. This is
478 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
479 >    raised here, but it may still be more appropriate to validate a post and signal
480 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
481 >
482 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
483 >    separated list. Each library name on the list is tried in turn, in left to right
484 >    order with the first found being used as the firebird library. By default, on Linux,
485 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
486 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
487 >
488 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
489 >    then it will still attempt to access the database via the Firebird Server and will
490 >    require a username and password. If only the pathname is given, then the username
491 >    and password should be omitted and the unix file permissions are used to grant
492 >    access.

494 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
495 >
496 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
497 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
498 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
499 >    corresponds to a row of the linked DataSource. Any data aware control on the
500 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
501 >
502 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
503 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
504 >   takes place during database access. This may be useful when there are performance issues with
505 >   the change of cursor. Setting the property to false suppresses the change of cursor.
506 >
507 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
508 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
509 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
510 >   making all changes permanent immediately rather than when the transaction is explicitly
511 >   committed.
512 >
513 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
514 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

520 > IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
521 >
522 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
523 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
524 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
525 >   complexity.
526 >
527 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
528 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
529 >   These are:
530 >
531 >   - TIBLookupComboEditBox
532 >   - TIBDynamicGrid
533 >   - TIBTreeview
534 >
535 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
536 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
537 >   to revise the available list and restrict it to items that are prefixed by the
538 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
539 >   newly typed entry to be added to the list dataset and included in the available
540 >   list items.
541 >
542 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
543 >   - automatic resizing of selected columns to fill the available row length
544 >   - automatic positioning and sizing of a "totals" control, typically at the
545 >     column footer, on a per column basis.
546 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
547 >     A second click on the same header cell reversed the sort order.
548 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
549 >     is automatically expanded and a panel superimposed on it. The panel can have any
550 >     number of child controls, typically data aware controls with the same datasource
551 >     as the grid allowing for editing of additional fields and more complex editors.
552 >   - Reselection of the same row following resorting.
553 >   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
554 >     Its properties are specified on a per column basis and allows for one or more
555 >     columns to have their values selected from a list provided by a dataset.
556 >     Autocomplete and autoinsert are also available. The existing picklist editor
557 >     is unaffected by the extension.
558 >
559 >   TIBTreeView is a data aware TCustomTreeView.
560 >
561 > 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
562 >   zero scale will no longer return an error. An Int64 will be returned instead.
563 >
564 > 4. TIBTransaction now has events for Before and After Transaction End and a new function
565 >   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
566 >
567 > 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
568 >   repeated multiple times.
569 >
570 > 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
571 >   check used to get in the way of using Stored Procedures, and "Update or Insert"
572 >   statements.
573 >
574 > 7. Insert, Modify and Delete property Editors now support Query Generation from
575 >   Stored Procedures.
576 >
577 > 8. Three new examples illustrate the use of the new IB Controls
578 >
579 >
