2 >
3 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 > all previous copies of the IBX source code tree before installing this release.
5 >
6 > The IBX packages used by most users have not changed, with one exception. The
7 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 > to use the IBServices unit in your applications, please add the iblegacyServices
9 > to the list of dependencies. To do this, open the Project Inspector and select
10 > Add->New Requirement and select "ibLegacyServices" from the list of available
11 > packages.
12 >
13 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 >   the IBServices unit providing what is intended to be a clearer and easier to
15 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 >   more information and the guide to "Firebird Service Management Using IBX".
17 >   As indicated above, the legacy services components are still available and
18 >   provided in a separate package. There is no need to update working applications
19 >   using the older versions except for an additional package dependency.
20 >
21 > 2. The IBX packages and source code tree have been re-organised in an attempt to
22 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 >   new set of IBX packages.
25 >
26 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 >   updated to use the new Services API components.
28 >
29 > 4. The iblocal package has been updated to use the new Services API components.
30 >
31 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 >   TIBXSecurityService. It had been wrongly classified in the previous version
33 >   as a per database configuration item. It is global to a server and hence
34 >   correctly positioned as part of the Security Package. In the DBAdmin example,
35 >   the setting has moved to the mappings page.
36 >
37 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 >   are ignored.
39 >
40 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 >   closed before the database is dropped. Before and After Disconnect event handlers
42 >   are also fired.
43 >
44 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 >   is started and not just the first time.
46 >
47 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 >   depenendency with comp type.
49 >
50 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51 >
52 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 >    then this is recognised and not ignored.
54 >
55 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59 >
60 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 >    counters for the select query. Note: stats accumulate after each fetch from
63 >    the database. To get total query cost after open, call the "Last" method
64 >    and then GetPerfStatistics.
65 >
66 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67 >
68 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 >    in parenthesises.
70 >
71 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 >    SQL identifiers are always delimited by double quotes. If false, then they are
73 >    only delimited if the identifier is a reserved word, contains lower case or special
74 >    characters. Set this property to true to retain previous behaviour.
75 >
76 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78 >
79 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 >       property MasterDetailDelay: integer {defaults to zero}
81 >
82 >    When non-zero and the dataset is a detail table referencing a master table
83 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 >    then a synchronisation delay is added (in milliseconds) between the master
85 >    row changing and the detail dataset being re-opened. If the master dataset
86 >    is scrolled before the delay expires then the delay is reset. This can be used
87 >    to avoid performance overheads when scrolling through a large master dataset.
88 >
89 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
90 >    chreads unit must be included in your project. TTimer is not used in order
91 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 >
93 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 >    with Extract Option eoDatabase.
95 >
96 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 >    When a deLayoutChanged event is reported on the ListSource dataset, the
98 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 >    relationship with the control's datasource (master).
100 >
101 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102 >
103 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
105 >
106 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107 >    DDL (Firebird 3 and later only).
108 >
109 > 22. TIBLookupComboBox Autocomplete Fixes:
110 >    i. Only appended text is now selected after autocomplete.
111 >    ii. Uppercase keys no longer ignored for autocomplete.
112 >    iii. Retain Prefix case is now honoured correctly.
113 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114 >        before autocomplete performed. i.e. behaviour now the same as when
115 >        no DataSource assigned.
116 >
117 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 >    between SQL statements.
119 >
120 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121 >    ObjectNames are converted to upper case before matching against metadata object
122 >    names, unless the objectname is delimited by double quotes, in which case, the
123 >    double quotes are removed and the remaining string is used (unmodified) to match
124 >    against the metadata object name.
125 >
126 >    If true then the ObjectName is used as is without modification and matched
127 >    against the metadata object name. No attempt is made to remove double quotes.
128 >
129 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130 >    with eoTrigger, these extract types can be used to select only Database Triggers,
131 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
132 >
133 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
134 >    statement separate character is now reset to the default (';').
135 >
136 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
137 >
138 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
139 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
140 > RELEASE.
141 >
142 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
143 >
144 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
145 >
146 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
147 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
148 >   information). However, this is also a very useful mechanism for returning updated computed by
149 >   column values. Values returned as a result of executing an Insert or Update statement
150 >   replace existing values in the current row for each corresponding column.
151 >
152 >   Previously, if a dataset's select query included read only (computed by) fields then
153 >   an automatic row refresh was performed after an insert or update query had been processed,
154 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
155 >   that an automatic refresh is no longer performed if an insert or update query contains
156 >   a returning clause that updates one or more fields on the current row. A full row
157 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
158 >   field values and the select query contains read only fields. Use of Insert/update
159 >   returning should be significantly more efficient than executing a refresh query.
160 >
161 >   This behaviour change is intended to be backwards compatible and there should be no need to change
162 >   existing programs, other than to improve performance by using the new capability.
163 >
164 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
165 >   they are called when the dataset row is being deleted, there is no value in
166 >   updating the current record from the query result. Instead, a new event handler
167 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
168 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
169 >   by the query. The event handler can then interrogate the query results and
170 >   perform whatever action is necessary. For example to confirm, to the user,
171 >   the deletion of a row with the returned values.
172 >
173 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
174 >   any Computed By or Identity Columns. The IBTables example has been updated to
175 >   illustrate the computation of the employee Full Name on update.
176 >
177 > 5. TIBTable: The GeneratorField property is now published.
178 >
179 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
180 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
181 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
182 >   each Identity column after the insert is executed.
183 >
184 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
185 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
186 >   Insert..Returning clause.
187 >
188 > 8. TIBGenerator: small performance improvement by not preparing query each time
189 >   a new value is generated.
190 >
191 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
192 >
193 > 10. Property editors will now sync table name to a System Table when "Include System
194 >    Tables" is selected and the query is for a System Table.
195 >
196 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
197 >    values are no longer converted to milliseconds from TDateTime and then back again
198 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
199 >
200 > 12. Property Editors handling of Stored Procedures.
201 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
202 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
203 >      query).
204 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
205 >
206 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
207 >    can be used to select a package. If non-empty, the stored procedure name is
208 >    expected to be a stored procedure defined in the specified package and the
209 >    generated SQL will be as required for a stored procedure located in a package.
210 >
211 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
212 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
213 >    which a stored procedure can be selected. With no package name selected, non-package
214 >    stored procedures are listed.
215 >
216 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
217 >    for password on reconnect.
218 >
219 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
220 >    and character set name.
221 >
222 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
223 >    DB info lookups"
224 >
225 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
226 >
227 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
228 >
229 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
230 >    parameters. This stops an exception being raised when the field cannot be
231 >    located in the record buffer.
232 >
233 > 21. Property Editors now automatically include System Tables when opened and when the query table
234 >    is a System Table.
235 >
236 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
237 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
238 >
239 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
240 >    add the SPB item isc_spb_expected_db. This names a database using
241 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
242 >    database. examples/services re-written to illustrate use of "expected_db".
243 >
244 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
245 >    This avoids truncated backups when the server returns a timeout (busy) response.
246 >
247 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
248 >
249 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
250 >    databasenames. These are respectively expanded to the local system's temp directory
251 >    (including trailing delimiter) or to a prescribed data directory (including
252 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
253 >    in the user's home directory. The hidden directory name is either the string returned
254 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
255 >    Under Windows, the directory is the same as the Data Directory as decribed
256 >    above but instead prefixed by the User's application data path. These may be
257 >    used to improve application portability for Personal Databases.
258 >
259 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
260 >    this has not worked for a long time and is not useful either. FieldDefs should be
261 >    managed using the Fields Editor as with any other dataset. To access the fields
262 >    editor for a TIBTable component, double click on the component. The fields editor
263 >    is then displayed.
264 >
265 > 28. TIBDatabaseInfo: new properties/function
266 >     * DateDBCreated (returns date/time database created)
267 >     * TransactionCount (returns no. of active transactions)
268 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
269 >     * PagesFree (Firebird 3 or later)
270 >     * PagesUsed (Firebird 3 or later)
271 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
272 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
273 >
274 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
275 >
276 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
277 >
278 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
279 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
280 >
281 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
282 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
283 >    firing during backup and restore.
284 >
285 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
286 >    for verbose output using the new property "StatisticsRequested".
287 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
288 >
289 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
290 >
291 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
292 >    palette. This uses the online validation feature added in Firebird 2.5. The
293 >    services's properties enable inclusion/exclusion of tables and indexes using
294 >    regular expressions. See.
295 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
296 >
297 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
298 >    option on a database.
299 >
300 > 37. TIBCustomService: Assign method implemented to allow copying of service login
301 >    context between service API components. "Detach" method now only detaches
302 >    service when last reference to the service interface detaches. Tidy up of
303 >    code for SetActive and Attach methods including password hiding.
304 >
305 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
306 >    and used to determine the auth method and protocol used for the connection.
307 >
308 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
309 >    a Create Database Statement generated by IBX.
310 >
311 > 40. All IBServices now have an additional published property "PortNo". This may
312 >    be set to a non-standard port number when necessary. If zero then the default
313 >    port number is used.
314 >
315 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
316 >    and not just the mouse.
317 >
318 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
319 >
320 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
321 >    image index and selected image index for each node to be set from a database field.
322 >
323 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
324 >    then database schema includes grants to all users. If not present then the
325 >    only user grants included are those to User PUBLIC.
326 >
327 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
328 >    and child nodes in dataset.
329 >
330 >
331 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
332 >
333 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
334 >   changes.
335 >
336 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
337 >   Bug could result in truncated multi-byte character set values.
338 >
339 > 3. Changes consequential on moving fbintf character set utility functions from
340 >   IFirebirdAPI to IAttachment.
341 >
342 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
343 >
344 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
345 >   results in autocomplete ignoring prefix text.
346 >
347 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
348 >   entering a new name into the text box.
349 >
350 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
351 >   Firebird rather than recomputing it.
352 >
353 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
354 >   screen centre. Previously some were "poDesigned" which may be inappropriate
355 >   for multi monitor desktops.
356 >
357 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
358 >
359 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
360 >    a transaction and always reset the object.
361 >
362 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
363 >
364 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
365 >
366 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
367 >    to a gbak format archive.
368 >
369 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
370 >
371 > 16. IBLocaldb: Drop database if error creating an empty database.
372 >
373 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
374 >    unless selected node not in current dataset.
375 >
376 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
377 >    to TIBCustomService, and IBlocalDB code tidy up.
378 >
379 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
380 >    behaviour due to uninitialised variable.
381 >
382 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
383 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
384 >
385 > 21. IBSQL: When Database changed ensure that all resources are freed.
386 >
387 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
388 >
389 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
390 >    * Line Wrap on SQL Token boundaries (on user command)
391 >    * auto-complete table names in drop down list of table names
392 >    * Double click on tablename or field name adds to SQL text
393 >
394 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
395 >
396 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
397 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
398 >    workaround for a problem in fpc 3.0.4 win64).
399 >
400 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
401 >
402 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
403 >
404 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
405 >
406 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
407 >   include remote system name.
408 >
409 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
410 >   tables when data included in output.
411 >
412 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
413 >   and timing information to be written to stdout. This may be used to locate

432 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
433 >
434 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
435 >
436 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
437 >   hexadecimal notation.
438 >
439 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
440 >   using a simple XML format.
441 >
442 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
443 >   grants to these objects.
444 >
445 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
446 >   dependency problems restoring complex databases.
447 >
448 > 7. TIBXScript: This component has been restructured to allow for the processing of
449 >   embedded XML in INSERT statements and to support interactive sources in addition
450 >   to non-interactive data sources such as files.
451 >
452 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
453 >
454 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
455 >   SET SQL DIALECT
456 >   SET TERM
457 >   SET AUTODDL
458 >   SET BAIL
459 >   SET ECHO
460 >   SET COUNT
461 >   SET STATS
462 >   SET NAMES <character set>
463 >
464 > 10. IBVersion unit added to hold current IBX Version Number information.
465 >
466 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
467 >    and domain definitions.
468 >
469 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
470 >    fully supported.
471 >
472 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
473 >
474 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

478 > See also doc/IBX4LazarusGuide.pdf for important information on
479 > upgrading to IBX2.
480 >
481 > 1. Size property of TIBStringField is now the width in characters of the field
482 >   and not the byte length. This applies only to multi-byte character sets such
483 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
484 >   code is not recognised as a bug and hence this change to align the behaviour.
485 >   The TStringField change is expected in fpc 3.2.0.
486 >
487 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
488 >   true (default) then Size property value saved in the lfm is ignored. Size is
489 >   always set from the dynamic information read from the database. It is unclear
490 >   why anyone would want to override this and set Size to false.
491 >
492 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
493 >   block.
494 >
495 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
496 >   exist when an attempt is made to connect to it (run time only) then an attempt
497 >   is made to create the database.
498 >
499 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
500 >   has been successfully created as a result of a call to CreateDatabase or when
501 >   creating a database after it was found not to exist.
502 >
503 > 6.  DBControlGrid: a race condition could result in the wrong row image being
504 >    written to the cache. This has been avoided by a trip round the message
505 >    loop before rendering the row image.
506 >
507 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
508 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
509 >    known to risk corrupt rendering of row images when the control is first
510 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
511 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
512 >
513 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
514 >    a TDateEdit control located on an editor panel.
515 >
516 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
517 >
518 > 10. DBControlGrid: Removed memory leak when updating rows.
519 >
520 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

526 >   http://bugs.freepascal.org/view.php?id=30622.
527 >
528 > 2. DBLog option removed from TIBStatisticalService - not supported by server
529 >   since Firebird 1.5.
530 >
531 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
532 >   similar.
533 >
534 > 4. IBCodePage: updated mapping between codepages and character id.
535 >
536 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
537 >   Firebird. Character sets with a char width of two are not UTF16.
538 >
539 > 6. Strings received from the database are now always transliterated into UTF8
540 >   regardless of the database character set or connection character set. This
541 >   is for compatibility with the LCL.

544 >
545 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
546 >   read in an entire blob just to get the size of the blob. General performance
547 >   improvement when opening datasets containing blobs.
548 >
549 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
550 >
551 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
552 >   is now used.
553 >
554 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
555 >   determined.
556 >
557 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
558 >
559 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
560 >   lazarus 1.6.0
561 >
562 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"

566 >
567 > 1. No character set specified for connection: when a text blob is retrieved, the
568 >  character set is determined by looking up the native character set using then
569 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
570 >  set as the connection.
571 >
572 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
573 >   for Login Dialog returing a change to the database path.
574 >
575 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
576 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
577 >   entered value to be saved on a project specific basis (design time only).
578 >
579 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
580 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
581 >   Otherwise, it sets the column text to the selected ListField Value.
582 >
583 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
584 >   column width.
585 >
586 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
587 >   and a case insensitive search is requested.
588 >
589 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
590 >   or column ListSource.
591 >
592 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
593 >   unprepare) when closing and the text has not changed.
594 >
595 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
596 >   Less likely to cause a cursor re-use error on Windows.
597 >
598 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
599 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
600 >
601 > 11. TIBTreeView: Guard against nil destination on record changed
602 >
603 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
604 >    string type with the code page set to reflect the returned field encoding after
605 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
606 >    earlier versions.
607 >
608 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
609 >    will now result in transliteration to the code page specified for the Firebird driver
610 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
611 >
612 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
613 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
614 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
615 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
616 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
617 >    the GETACP is used to determine the Windows code page.
618 >
619 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
620 >    name used as the lc_ctype when the database was opened. Only valid while the
621 >    Database is connected.
622 >
623 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
624 >    id that corresponds to the DefaultCharSetName.

628 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
629 >   path is given and database attach fails due to access permission issues on the
630 >   temp directory or security database, then the attach is retried with "localhost:"
631 >   prefixing the databasename. This should avoid problems when the database has to
632 >   be accessed by a local (e.g. classic) server and libfbembed is used.
633 >
634 > 2. Windows: revised search order for Firebird DLL:
635 >     i.   The Firebird Embedded Server in the application Directory.
636 >     ii.  If the FIREBIRD environment variable is set then the directory this
637 >          points to is searched for the FB Client DLL and then then underlying
638 >          "bin" directory.
639 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
640 >          is used to locate the Firebird installation directory and the underlying
641 >          "bin" directory is searched for the FB Client DLL.
642 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
643 >          are searched for the FB Client DLL.
644 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
645 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
646 >
647 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
648 >   See doc/readme.scriptengine and example applications.
649 >
650 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
651 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
652 >   See dpc/readme.localdatabase and example applications.
653 >
654 > 5. IBDynamicGrid: Reordering on column header click should now also work for
655 >   dynamic columns.
656 >
657 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
658 >   between incrementing/decrementing the lock count and signalling the event.

662 > 1.3.2 was never formally released and only made available as beta copies.
663 >
664 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
665 >
666 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
667 >
668 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
669 >
670 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
671 >   i.e. when it is a calculated field
672 >
673 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
674 >   This problem was due to a race condition between recalculating row heights and
675 >   determining which row was selected by the mouse click. The row height calculation
676 >   is now deferred by an extra trip round the message loop allowing the row to
677 >   be always calculated on the current grid layout rather than risking it being
678 >   calculated on the grid layout after the expanded row has been shrunk.
679 >
680 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
681 >   Windows.
682 >
683 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
684 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
685 >   to be determined at runtime. See doc/readme.charactersets.html.
686 >
687 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
688 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
689 >
690 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
691 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
692 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
693 >
694 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
695 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
696 >   implies no truncation.
697 >
698 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
699 >
700 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
701 >   (avoids "Not in Edit Mode" error).
702 >
703 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
704 >
705 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
706 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
707 >
708 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
709 >
710 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
711 >
712 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
713 >
714 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

718 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
719 >
720 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids

722 >
723 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
724 >
725 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
726 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
727 >
728 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
729 >     keyed in i.e. when autocomplete not performed
730 >
731 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
732 >     console mode applications with all LCL required functions (builtin dialogs and
733 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
734 >     not included in your project, IBX should compile and link with a console mode program.
735 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
736 >     console mode application or the IDE will automatically assume that your
737 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
738 >
739 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
740 >     to use the built in dialogs and cursor management. IBDialogs is
741 >     included by default if "ibexpress" is in your project source's "uses" clause.
742 >     This should be the case for all projects created through the IDE. This is why
743 >     you do not want to add the ibexpress package to console mode applications. The
744 >     ibexpressconsolemode package has been created to allow console mode programs
745 >     to avoid adding LCL dependencies when using IBX, while still having the
746 >     unit search paths set up correctly.
747 >
748 >     Existing users should check to ensure that the "ibexpress" unit is included in
749 >     each project's source file (*.lpr).
750 >
751 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
752 >     exists, you have to first open the package in the IDE and then close it. This
753 >     adds it to the most recently accessed packages list. To make it permanently
754 >     available, add the package name to lazarus' staticpackages.inc file.
755 >
756 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
757 >
758 > 7.   SQL Parser can now accept quoted strings that include new lines
759 >
760 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
761 >     of text on start of edit. This is particularly useful when tabbing to a
762 >     column and then inserting text.
763 >
764 > 9.   New Examples provided for IB Services and ISQLMonitor.
765 >
766 > 10. Fix error when writing to blob streams that recorded only the last buffer
767 >    write in the blob stream. In most cases, this did not cause a problem as the
768 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
769 >    of a graphic type prefix was lost which caused a problem when the image could
770 >        not be automatically recognised.
771 >
772 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
773 >    already open" errors due to random numbers used for the cursor name being identical.
774 >
775 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
776 >    when opening the table and the Primary Key is the last or only column in the
777 >    table. Thanks to Rick Hoover for the fix.
778 >
779 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
780 >    of "UTF-8", and update list of available database character sets. Existing
781 >    users should check the current lc_ctype setting in their applications.

797 >
798 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
799 >
