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

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

404   1. IBBlob: Defer reading of blob until read method called. This avoids having to
405     read in an entire blob just to get the size of the blob. General performance
