3 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
4 >   read in an entire blob just to get the size of the blob. General performance
5 >   improvement when opening datasets containing blobs.
6 >
7 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
8 >
9 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
10 >   is now used.
11 >
12 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
13 >   determined.
14 >
15 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
16 >
17 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
18 >   lazarus 1.6.0
19 >
20 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
21 >   compilation error.
22 >
23 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
24 >
25 > 1. No character set specified for connection: when a text blob is retrieved, the
26 >  character set is determined by looking up the native character set using then
27 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
28 >  set as the connection.
29 >
30 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
31 >   for Login Dialog returing a change to the database path.
32 >
33 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
34 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
35 >   entered value to be saved on a project specific basis (design time only).
36 >
37 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
38 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
39 >   Otherwise, it sets the column text to the selected ListField Value.
40 >
41 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
42 >   column width.
43 >
44 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
45 >   and a case insensitive search is requested.
46 >
47 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
48 >   or column ListSource.
49 >
50 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
51 >   unprepare) when closing and the text has not changed.
52 >
53 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
54 >   Less likely to cause a cursor re-use error on Windows.
55 >
56 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
57 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
58 >
59 > 11. TIBTreeView: Guard against nil destination on record changed
60 >
61 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
62 >    string type with the code page set to reflect the returned field encoding after
63 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
64 >    earlier versions.
65 >
66 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
67 >    will now result in transliteration to the code page specified for the Firebird driver
68 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
69 >
70 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
71 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
72 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
73 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
74 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
75 >    the GETACP is used to determine the Windows code page.
76 >
77 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
78 >    name used as the lc_ctype when the database was opened. Only valid while the
79 >    Database is connected.
80 >
81 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
82 >    id that corresponds to the DefaultCharSetName.
83 >
84 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
85 >
86 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
87 >   path is given and database attach fails due to access permission issues on the
88 >   temp directory or security database, then the attach is retried with "localhost:"
89 >   prefixing the databasename. This should avoid problems when the database has to
90 >   be accessed by a local (e.g. classic) server and libfbembed is used.
91 >
92 > 2. Windows: revised search order for Firebird DLL:
93 >     i.   The Firebird Embedded Server in the application Directory.
94 >     ii.  If the FIREBIRD environment variable is set then the directory this
95 >          points to is searched for the FB Client DLL and then then underlying
96 >          "bin" directory.
97 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
98 >          is used to locate the Firebird installation directory and the underlying
99 >          "bin" directory is searched for the FB Client DLL.
100 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
101 >          are searched for the FB Client DLL.
102 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
103 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
104 >
105 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
106 >   See doc/readme.scriptengine and example applications.
107 >
108 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
109 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
110 >   See dpc/readme.localdatabase and example applications.
111 >
112 > 5. IBDynamicGrid: Reordering on column header click should now also work for
113 >   dynamic columns.
114 >
115 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
116 >   between incrementing/decrementing the lock count and signalling the event.
117 >
118 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
119 >
120 > 1.3.2 was never formally released and only made available as beta copies.
121 >
122 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
123 >
124 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
125 >
126 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
127 >
128 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
129 >   i.e. when it is a calculated field
130 >
131 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
132 >   This problem was due to a race condition between recalculating row heights and
133 >   determining which row was selected by the mouse click. The row height calculation
134 >   is now deferred by an extra trip round the message loop allowing the row to
135 >   be always calculated on the current grid layout rather than risking it being
136 >   calculated on the grid layout after the expanded row has been shrunk.
137 >
138 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
139 >   Windows.
140 >
141 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
142 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
143 >   to be determined at runtime. See doc/readme.charactersets.html.
144 >
145 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
146 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
147 >
148 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
149 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
150 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
151 >
152 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
153 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
154 >   implies no truncation.
155 >
156 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
157 >
158 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
159 >   (avoids "Not in Edit Mode" error).
160 >
161 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
162 >
163 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
164 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
165 >
166 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
167 >
168 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
169 >
170 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
171 >
172 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
173 >
174 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
175 >
176 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
177 >
178 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
179 >     problem with row size when exception is called.
180 >
181 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
182 >
183 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
184 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
185 >
186 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
187 >     keyed in i.e. when autocomplete not performed
188 >
189 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
190 >     console mode applications with all LCL required functions (builtin dialogs and
191 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
192 >     not included in your project, IBX should compile and link with a console mode program.
193 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
194 >     console mode application or the IDE will automatically assume that your
195 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
196 >
197 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
198 >     to use the built in dialogs and cursor management. IBDialogs is
199 >     included by default if "ibexpress" is in your project source's "uses" clause.
200 >     This should be the case for all projects created through the IDE. This is why
201 >     you do not want to add the ibexpress package to console mode applications. The
202 >     ibexpressconsolemode package has been created to allow console mode programs
203 >     to avoid adding LCL dependencies when using IBX, while still having the
204 >     unit search paths set up correctly.
205 >
206 >     Existing users should check to ensure that the "ibexpress" unit is included in
207 >     each project's source file (*.lpr).
208 >
209 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
210 >     exists, you have to first open the package in the IDE and then close it. This
211 >     adds it to the most recently accessed packages list. To make it permanently
212 >     available, add the package name to lazarus' staticpackages.inc file.
213 >
214 >         Thanks to Julio Jiménez for suggesting support of console mode.
215 >
216 > 7.   SQL Parser can now accept quoted strings that include new lines
217 >
218 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
219 >     of text on start of edit. This is particularly useful when tabbing to a
220 >     column and then inserting text.
221 >
222 > 9.   New Examples provided for IB Services and ISQLMonitor.
223 >
224 > 10. Fix error when writing to blob streams that recorded only the last buffer
225 >    write in the blob stream. In most cases, this did not cause a problem as the
226 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
227 >    of a graphic type prefix was lost which caused a problem when the image could
228 >        not be automatically recognised.
229 >
230 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
231 >    already open" errors due to random numbers used for the cursor name being identical.
232 >
233 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
234 >    when opening the table and the Primary Key is the last or only column in the
235 >    table. Thanks to Rick Hoover for the fix.
236 >
237 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
238 >    of "UTF-8", and update list of available database character sets. Existing
239 >    users should check the current lc_ctype setting in their applications.
240 >
241 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
242 >
243 > 1.  Firebird Services: avoid List Index error when opening a service with an
244 >    empty Params property.
245 >
246 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
247 >    Link now set up in Loaded method - avoids occasional failure to apply
248 >    SQL markup on initial open.
249 >
250 > 3.  "Employees" example performance improvements when scrolling.
251 >
252 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
253 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
254 >    random image cached).
255 >
256 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
257 >
258 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
259 >    even when further rows exist.
260 >
261 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
262 >    always be derived from panel height and setting this property can cause confusion.
263 >    Note for existing projects: to avoid a missing property error at run time,
264 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
265 >    in order to remove the property value from the lfm.
266 >
267 >
268 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
269 >
270 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
271 >    call Prepare before setting parameter values.
272 >
273 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
274 >
275 > 3.  Code tidyup and more robust handling of dsql information result vector.
276 >
277 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
278 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
279 >    and "AfterExecQuery". The first three are called after the same event is called
280 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
281 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
282 >    enable monitoring of transaction status changes for a given transaction to be
283 >    handled in a single place. For example, when a change to the dataset occurs
284 >    an indicator can be set that shows the user that in order to save changes,
285 >    the transaction should be committed.  Rather than doing this per dataset, this
286 >    can now be done per transaction.
287 >
288 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
289 >    the dataset is scrolled. However, any changes to the current row are, by default,
290 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
291 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
292 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
293 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
294 >    then IBX will attempt to post any unsaved changes before the dataset is closed
295 >    (and after the BeforeClose event handler is called). The exception is when the
296 >    dataset is being closed as a result of a transaction rollback. In this case,
297 >    no action is taken and any unsaved  changes are discarded. This avoids both
298 >    unnecessary overhead and the risk that a validation error may occur in the Post
299 >    raising an exception and thereby preventing a rollback.
300 >
301 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
302 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
303 >    width. Display Widths are now corrected by dividing by the max byte width per character.
304 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
305 >    the byte width divided by 4. The byte width of each character set is determined
306 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
307 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
308 >
309 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
310 >
311 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
312 >    control loses focus. Default Key press default interval reduced to 200ms.
313 >
314 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
315 >    when dataset rows are less than visible rows.
316 >
317 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
318 >    does not exist or DataSet is empty. More responsive on dataset open. New event
319 >    OnRestorePosition. Column sort disabled if no header row.
320 >
321 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
322 >    while dataset state is dsInsert. Avoids posting errors.
323 >
324 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
325 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
326 >
327 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
328 >
329 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
330 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
331 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
332 >    always "posts" the current record regardless or whether or not it may be more appropriate
333 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
334 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
335 >    as the first action of the "Post" method and allows the handler to convert the Post
336 >    into a Cancel if that is the appropriate action on moving to a different row. This is
337 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
338 >    raised here, but it may still be more appropriate to validate a post and signal
339 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
340 >
341 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
342 >    separated list. Each library name on the list is tried in turn, in left to right
343 >    order with the first found being used as the firebird library. By default, on Linux,
344 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
345 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
346 >
347 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
348 >    then it will still attempt to access the database via the Firebird Server and will
349 >    require a username and password. If only the pathname is given, then the username
350 >    and password should be omitted and the unix file permissions are used to grant
351 >    access.

354  
355   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
356      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
357      that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
358 <    correspondes to a row of the linked DataSource. Any data aware control on the
358 >    corresponds to a row of the linked DataSource. Any data aware control on the
359      replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
360  
361   2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
