3 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
4 >   when target codepage is CP_NONE. This is a workaround for
5 >   http://bugs.freepascal.org/view.php?id=30622.
6 >
7 > 2. DBLog option removed from TIBStatisticalService - not supported by server
8 >   since Firebird 1.5.
9 >
10 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
11 >   similar.
12 >
13 > 4. IBCodePage: updated mapping between codepages and character id.
14 >
15 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
16 >   Firebird. Character sets with a char width of two are not UTF16.
17 >
18 > 6. Strings received from the database are now always transliterated into UTF8
19 >   regardless of the database character set or connection character set. This
20 >   is for compatibility with the LCL.

23 >
24 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
25 >   read in an entire blob just to get the size of the blob. General performance
26 >   improvement when opening datasets containing blobs.
27 >
28 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
29 >
30 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
31 >   is now used.
32 >
33 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
34 >   determined.
35 >
36 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
37 >
38 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
39 >   lazarus 1.6.0
40 >
41 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
42 >   compilation error.
43 >
44 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
45 >
46 > 1. No character set specified for connection: when a text blob is retrieved, the
47 >  character set is determined by looking up the native character set using then
48 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
49 >  set as the connection.
50 >
51 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
52 >   for Login Dialog returing a change to the database path.
53 >
54 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
55 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
56 >   entered value to be saved on a project specific basis (design time only).
57 >
58 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
59 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
60 >   Otherwise, it sets the column text to the selected ListField Value.
61 >
62 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
63 >   column width.
64 >
65 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
66 >   and a case insensitive search is requested.
67 >
68 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
69 >   or column ListSource.
70 >
71 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
72 >   unprepare) when closing and the text has not changed.
73 >
74 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
75 >   Less likely to cause a cursor re-use error on Windows.
76 >
77 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
78 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
79 >
80 > 11. TIBTreeView: Guard against nil destination on record changed
81 >
82 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
83 >    string type with the code page set to reflect the returned field encoding after
84 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
85 >    earlier versions.
86 >
87 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
88 >    will now result in transliteration to the code page specified for the Firebird driver
89 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
90 >
91 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
92 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
93 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
94 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
95 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
96 >    the GETACP is used to determine the Windows code page.
97 >
98 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
99 >    name used as the lc_ctype when the database was opened. Only valid while the
100 >    Database is connected.
101 >
102 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
103 >    id that corresponds to the DefaultCharSetName.
104 >
105 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
106 >
107 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
108 >   path is given and database attach fails due to access permission issues on the
109 >   temp directory or security database, then the attach is retried with "localhost:"
110 >   prefixing the databasename. This should avoid problems when the database has to
111 >   be accessed by a local (e.g. classic) server and libfbembed is used.
112 >
113 > 2. Windows: revised search order for Firebird DLL:
114 >     i.   The Firebird Embedded Server in the application Directory.
115 >     ii.  If the FIREBIRD environment variable is set then the directory this
116 >          points to is searched for the FB Client DLL and then then underlying
117 >          "bin" directory.
118 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
119 >          is used to locate the Firebird installation directory and the underlying
120 >          "bin" directory is searched for the FB Client DLL.
121 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
122 >          are searched for the FB Client DLL.
123 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
124 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
125 >
126 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
127 >   See doc/readme.scriptengine and example applications.
128 >
129 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
130 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
131 >   See dpc/readme.localdatabase and example applications.
132 >
133 > 5. IBDynamicGrid: Reordering on column header click should now also work for
134 >   dynamic columns.
135 >
136 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
137 >   between incrementing/decrementing the lock count and signalling the event.
138 >
139 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
140 >
141 > 1.3.2 was never formally released and only made available as beta copies.
142 >
143 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
144 >
145 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
146 >
147 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
148 >
149 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
150 >   i.e. when it is a calculated field
151 >
152 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
153 >   This problem was due to a race condition between recalculating row heights and
154 >   determining which row was selected by the mouse click. The row height calculation
155 >   is now deferred by an extra trip round the message loop allowing the row to
156 >   be always calculated on the current grid layout rather than risking it being
157 >   calculated on the grid layout after the expanded row has been shrunk.
158 >
159 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
160 >   Windows.
161 >
162 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
163 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
164 >   to be determined at runtime. See doc/readme.charactersets.html.
165 >
166 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
167 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
168 >
169 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
170 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
171 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
172 >
173 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
174 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
175 >   implies no truncation.
176 >
177 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
178 >
179 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
180 >   (avoids "Not in Edit Mode" error).
181 >
182 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
183 >
184 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
185 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
186 >
187 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
188 >
189 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
190 >
191 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
192 >
193 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
194 >
195 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
196 >
197 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
198 >
199 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
200 >     problem with row size when exception is called.
201 >
202 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
203 >
204 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
205 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
206 >
207 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
208 >     keyed in i.e. when autocomplete not performed
209 >
210 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
211 >     console mode applications with all LCL required functions (builtin dialogs and
212 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
213 >     not included in your project, IBX should compile and link with a console mode program.
214 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
215 >     console mode application or the IDE will automatically assume that your
216 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
217 >
218 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
219 >     to use the built in dialogs and cursor management. IBDialogs is
220 >     included by default if "ibexpress" is in your project source's "uses" clause.
221 >     This should be the case for all projects created through the IDE. This is why
222 >     you do not want to add the ibexpress package to console mode applications. The
223 >     ibexpressconsolemode package has been created to allow console mode programs
224 >     to avoid adding LCL dependencies when using IBX, while still having the
225 >     unit search paths set up correctly.
226 >
227 >     Existing users should check to ensure that the "ibexpress" unit is included in
228 >     each project's source file (*.lpr).
229 >
230 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
231 >     exists, you have to first open the package in the IDE and then close it. This
232 >     adds it to the most recently accessed packages list. To make it permanently
233 >     available, add the package name to lazarus' staticpackages.inc file.
234 >
235 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
236 >
237 > 7.   SQL Parser can now accept quoted strings that include new lines
238 >
239 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
240 >     of text on start of edit. This is particularly useful when tabbing to a
241 >     column and then inserting text.
242 >
243 > 9.   New Examples provided for IB Services and ISQLMonitor.
244 >
245 > 10. Fix error when writing to blob streams that recorded only the last buffer
246 >    write in the blob stream. In most cases, this did not cause a problem as the
247 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
248 >    of a graphic type prefix was lost which caused a problem when the image could
249 >        not be automatically recognised.
250 >
251 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
252 >    already open" errors due to random numbers used for the cursor name being identical.
253 >
254 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
255 >    when opening the table and the Primary Key is the last or only column in the
256 >    table. Thanks to Rick Hoover for the fix.
257 >
258 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
259 >    of "UTF-8", and update list of available database character sets. Existing
260 >    users should check the current lc_ctype setting in their applications.
261 >
262 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
263 >
264 > 1.  Firebird Services: avoid List Index error when opening a service with an
265 >    empty Params property.
266 >
267 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
268 >    Link now set up in Loaded method - avoids occasional failure to apply
269 >    SQL markup on initial open.
270 >
271 > 3.  "Employees" example performance improvements when scrolling.
272 >
273 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
274 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
275 >    random image cached).
276 >
277 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
278 >
279 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
280 >    even when further rows exist.
281 >
282 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
283 >    always be derived from panel height and setting this property can cause confusion.
284 >    Note for existing projects: to avoid a missing property error at run time,
285 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
286 >    in order to remove the property value from the lfm.

376   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
377      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
