4 > See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
5 > upgrading to IBX2.
6 >
7 > 1. Size property of TIBStringField is now the width in characters of the field
8 >   and not the byte length. This applies only to multi-byte character sets such
9 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
10 >   code is not recognised as a bug and hence this change to align the behaviour.
11 >   The TStringField change is expected in fpc 3.2.0.
12 >
13 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
14 >   true (default) then Size property value saved in the lfm is ignored. Size is
15 >   always set from the dynamic information read from the database. It is unclear
16 >   why anyone would want to override this and set Size to false.
17 >
18 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
19 >   block.
20 >
21 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
22 >   exist when an attempt is made to connect to it (run time only) then an attempt
23 >   is made to create the database.
24 >
25 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
26 >   has been successfully created as a result of a call to CreateDatabase or when
27 >   creating a database after it was found not to exist.
28 >
29 > 6.  DBControlGrid: a race condition could result in the wrong row image being
30 >    written to the cache. This has been avoided by a trip round the message
31 >    loop before rendering the row image.
32 >
33 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
34 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
35 >    known to risk corrupt rendering of row images when the control is first
36 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
37 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
38 >
39 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
40 >    a TDateEdit control located on an editor panel.
41 >
42 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
43 >
44 > 10. DBControlGrid: Removed memory leak when updating rows.
45 >
46 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
47 >

49 >
50 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
51 >   when target codepage is CP_NONE. This is a workaround for
52 >   http://bugs.freepascal.org/view.php?id=30622.
53 >
54 > 2. DBLog option removed from TIBStatisticalService - not supported by server
55 >   since Firebird 1.5.
56 >
57 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
58 >   similar.
59 >
60 > 4. IBCodePage: updated mapping between codepages and character id.
61 >
62 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
63 >   Firebird. Character sets with a char width of two are not UTF16.
64 >
65 > 6. Strings received from the database are now always transliterated into UTF8
66 >   regardless of the database character set or connection character set. This
67 >   is for compatibility with the LCL.
68 >
69 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
70 >
71 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
72 >   read in an entire blob just to get the size of the blob. General performance
73 >   improvement when opening datasets containing blobs.
74 >
75 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
76 >
77 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
78 >   is now used.
79 >
80 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
81 >   determined.
82 >
83 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
84 >
85 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
86 >   lazarus 1.6.0
87 >
88 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
89 >   compilation error.
90 >
91 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
92 >
93 > 1. No character set specified for connection: when a text blob is retrieved, the
94 >  character set is determined by looking up the native character set using then
95 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
96 >  set as the connection.
97 >
98 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
99 >   for Login Dialog returing a change to the database path.
100 >
101 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
102 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
103 >   entered value to be saved on a project specific basis (design time only).
104 >
105 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
106 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
107 >   Otherwise, it sets the column text to the selected ListField Value.
108 >
109 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
110 >   column width.
111 >
112 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
113 >   and a case insensitive search is requested.
114 >
115 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
116 >   or column ListSource.
117 >
118 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
119 >   unprepare) when closing and the text has not changed.
120 >
121 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
122 >   Less likely to cause a cursor re-use error on Windows.
123 >
124 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
125 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
126 >
127 > 11. TIBTreeView: Guard against nil destination on record changed
128 >
129 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
130 >    string type with the code page set to reflect the returned field encoding after
131 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
132 >    earlier versions.
133 >
134 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
135 >    will now result in transliteration to the code page specified for the Firebird driver
136 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
137 >
138 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
139 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
140 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
141 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
142 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
143 >    the GETACP is used to determine the Windows code page.
144 >
145 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
146 >    name used as the lc_ctype when the database was opened. Only valid while the
147 >    Database is connected.
148 >
149 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
150 >    id that corresponds to the DefaultCharSetName.
151 >
152 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
153 >
154 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
155 >   path is given and database attach fails due to access permission issues on the
156 >   temp directory or security database, then the attach is retried with "localhost:"
157 >   prefixing the databasename. This should avoid problems when the database has to
158 >   be accessed by a local (e.g. classic) server and libfbembed is used.
159 >
160 > 2. Windows: revised search order for Firebird DLL:
161 >     i.   The Firebird Embedded Server in the application Directory.
162 >     ii.  If the FIREBIRD environment variable is set then the directory this
163 >          points to is searched for the FB Client DLL and then then underlying
164 >          "bin" directory.
165 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
166 >          is used to locate the Firebird installation directory and the underlying
167 >          "bin" directory is searched for the FB Client DLL.
168 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
169 >          are searched for the FB Client DLL.
170 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
171 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
172 >
173 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
174 >   See doc/readme.scriptengine and example applications.
175 >
176 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
177 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
178 >   See dpc/readme.localdatabase and example applications.
179 >
180 > 5. IBDynamicGrid: Reordering on column header click should now also work for
181 >   dynamic columns.
182 >
183 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
184 >   between incrementing/decrementing the lock count and signalling the event.
185 >
186 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
187 >
188 > 1.3.2 was never formally released and only made available as beta copies.
189 >
190 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
191 >
192 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
193 >
194 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
195 >
196 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
197 >   i.e. when it is a calculated field
198 >
199 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
200 >   This problem was due to a race condition between recalculating row heights and
201 >   determining which row was selected by the mouse click. The row height calculation
202 >   is now deferred by an extra trip round the message loop allowing the row to
203 >   be always calculated on the current grid layout rather than risking it being
204 >   calculated on the grid layout after the expanded row has been shrunk.
205 >
206 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
207 >   Windows.
208 >
209 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
210 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
211 >   to be determined at runtime. See doc/readme.charactersets.html.
212 >
213 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
214 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
215 >
216 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
217 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
218 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
219 >
220 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
221 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
222 >   implies no truncation.
223 >
224 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
225 >
226 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
227 >   (avoids "Not in Edit Mode" error).
228 >
229 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
230 >
231 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
232 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
233 >
234 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
235 >
236 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
237 >
238 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
239 >
240 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
241 >
242 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
243 >
244 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
245 >
246 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
247 >     problem with row size when exception is called.
248 >
249 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
250 >
251 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
252 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
253 >
254 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
255 >     keyed in i.e. when autocomplete not performed
256 >
257 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
258 >     console mode applications with all LCL required functions (builtin dialogs and
259 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
260 >     not included in your project, IBX should compile and link with a console mode program.
261 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
262 >     console mode application or the IDE will automatically assume that your
263 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
264 >
265 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
266 >     to use the built in dialogs and cursor management. IBDialogs is
267 >     included by default if "ibexpress" is in your project source's "uses" clause.
268 >     This should be the case for all projects created through the IDE. This is why
269 >     you do not want to add the ibexpress package to console mode applications. The
270 >     ibexpressconsolemode package has been created to allow console mode programs
271 >     to avoid adding LCL dependencies when using IBX, while still having the
272 >     unit search paths set up correctly.
273 >
274 >     Existing users should check to ensure that the "ibexpress" unit is included in
275 >     each project's source file (*.lpr).
276 >
277 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
278 >     exists, you have to first open the package in the IDE and then close it. This
279 >     adds it to the most recently accessed packages list. To make it permanently
280 >     available, add the package name to lazarus' staticpackages.inc file.
281 >
282 >         Thanks to Julio Jiménez for suggesting support of console mode.
283 >
284 > 7.   SQL Parser can now accept quoted strings that include new lines
285 >
286 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
287 >     of text on start of edit. This is particularly useful when tabbing to a
288 >     column and then inserting text.
289 >
290 > 9.   New Examples provided for IB Services and ISQLMonitor.
291 >
292 > 10. Fix error when writing to blob streams that recorded only the last buffer
293 >    write in the blob stream. In most cases, this did not cause a problem as the
294 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
295 >    of a graphic type prefix was lost which caused a problem when the image could
296 >        not be automatically recognised.
297 >
298 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
299 >    already open" errors due to random numbers used for the cursor name being identical.
300 >
301 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
302 >    when opening the table and the Primary Key is the last or only column in the
303 >    table. Thanks to Rick Hoover for the fix.
304 >
305 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
306 >    of "UTF-8", and update list of available database character sets. Existing
307 >    users should check the current lc_ctype setting in their applications.
308 >
309 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
310 >
311 > 1.  Firebird Services: avoid List Index error when opening a service with an
312 >    empty Params property.
313 >
314 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
315 >    Link now set up in Loaded method - avoids occasional failure to apply
316 >    SQL markup on initial open.
317 >
318 > 3.  "Employees" example performance improvements when scrolling.
319 >
320 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
321 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
322 >    random image cached).
323 >
324 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
325 >
326 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
327 >    even when further rows exist.
328 >
329 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
330 >    always be derived from panel height and setting this property can cause confusion.
331 >    Note for existing projects: to avoid a missing property error at run time,
332 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
333 >    in order to remove the property value from the lfm.
334 >
335 >
336 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
337 >
338 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
339 >    call Prepare before setting parameter values.
340 >
341 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
342 >
343 > 3.  Code tidyup and more robust handling of dsql information result vector.
344 >
345 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
346 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
347 >    and "AfterExecQuery". The first three are called after the same event is called
348 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
349 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
350 >    enable monitoring of transaction status changes for a given transaction to be
351 >    handled in a single place. For example, when a change to the dataset occurs
352 >    an indicator can be set that shows the user that in order to save changes,
353 >    the transaction should be committed.  Rather than doing this per dataset, this
354 >    can now be done per transaction.
355 >
356 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
357 >    the dataset is scrolled. However, any changes to the current row are, by default,
358 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
359 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
360 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
361 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
362 >    then IBX will attempt to post any unsaved changes before the dataset is closed
363 >    (and after the BeforeClose event handler is called). The exception is when the
364 >    dataset is being closed as a result of a transaction rollback. In this case,
365 >    no action is taken and any unsaved  changes are discarded. This avoids both
366 >    unnecessary overhead and the risk that a validation error may occur in the Post
367 >    raising an exception and thereby preventing a rollback.
368 >
369 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
370 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
371 >    width. Display Widths are now corrected by dividing by the max byte width per character.
372 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
373 >    the byte width divided by 4. The byte width of each character set is determined
374 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
375 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
376 >
377 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
378 >
379 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
380 >    control loses focus. Default Key press default interval reduced to 200ms.
381 >
382 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
383 >    when dataset rows are less than visible rows.
384 >
385 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
386 >    does not exist or DataSet is empty. More responsive on dataset open. New event
387 >    OnRestorePosition. Column sort disabled if no header row.
388 >
389 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
390 >    while dataset state is dsInsert. Avoids posting errors.
391 >
392 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
393 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
394 >
395 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
396 >
397 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
398 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by

421 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
422 >
423 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
424 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
425 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
426 >    corresponds to a row of the linked DataSource. Any data aware control on the
427 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
428 >
429 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
430 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
431 >   takes place during database access. This may be useful when there are performance issues with
432 >   the change of cursor. Setting the property to false suppresses the change of cursor.
433 >
434 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
435 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
436 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
437 >   making all changes permanent immediately rather than when the transaction is explicitly
438 >   committed.
439 >
440 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
441 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

447 > IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
448 >
449 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
450 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
451 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
452 >   complexity.
453 >
454 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
455 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
456 >   These are:
457 >
458 >   - TIBLookupComboEditBox
459 >   - TIBDynamicGrid
460 >   - TIBTreeview
461 >
462 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
463 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
464 >   to revise the available list and restrict it to items that are prefixed by the
465 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
466 >   newly typed entry to be added to the list dataset and included in the available
467 >   list items.
468 >
469 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
470 >   - automatic resizing of selected columns to fill the available row length
471 >   - automatic positioning and sizing of a "totals" control, typically at the
472 >     column footer, on a per column basis.
473 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
474 >     A second click on the same header cell reversed the sort order.
475 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
476 >     is automatically expanded and a panel superimposed on it. The panel can have any
477 >     number of child controls, typically data aware controls with the same datasource
478 >     as the grid allowing for editing of additional fields and more complex editors.
479 >   - Reselection of the same row following resorting.
480 >   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
481 >     Its properties are specified on a per column basis and allows for one or more
482 >     columns to have their values selected from a list provided by a dataset.
483 >     Autocomplete and autoinsert are also available. The existing picklist editor
484 >     is unaffected by the extension.
485 >
486 >   TIBTreeView is a data aware TCustomTreeView.
487 >
488 > 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
489 >   zero scale will no longer return an error. An Int64 will be returned instead.
490 >
491 > 4. TIBTransaction now has events for Before and After Transaction End and a new function
492 >   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
493 >
494 > 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
495 >   repeated multiple times.
496 >
497 > 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
498 >   check used to get in the way of using Stored Procedures, and "Update or Insert"
499 >   statements.
500 >
501 > 7. Insert, Modify and Delete property Editors now support Query Generation from
502 >   Stored Procedures.
503 >
504 > 8. Three new examples illustrate the use of the new IB Controls
505 >
