1 < IBX Change Log  version                                                              (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1 > IBX Change Log  version                    (2.3-3) Wed, 26 Dec 2018 18:20:57 +0000
2 >
3 > This is rc1 for 2.2.3.
4 >
5 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "WireCompression".
6 >   If this property is set to true then the Client will request WireCompression for
7 >   the connection. Note: "WireCompression = true" must be set in the server's
8 >   "firebird.conf". This property is overridden if "WireCompression = true" is set
9 >   in the client "firebird.conf" when wire compression is always requested by the client.
10 >
11 > IBX Change Log  version                   (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
12 >
13 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
14 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
15 >   mode apps.
16 >
17 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
18 >   statement. This avoids problems if "Execute Block" is used as the Query.
19 >
20 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
21 >   internal SQL tokeniser routines.
22 >
23 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
24 >   as a select statement, with or without CTEs.
25 >
26 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
27 >
28 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
29 >   internal SQL tokeniser routines.
30 >
31 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
32 >    being raised for valid set statements processed by a data formatter.
33 >
34 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
35 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
36 >   the path of the Firebird Library used by the database/services connection.
37 >
38 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
39 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
40 >   services connection.
41 >
42 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
43 >   or param name is not a valid SQL identifier.
44 >
45 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
46 >    view of whether the text box should be editable when no DataSource is specified.
47 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
48 >    ReadOnly is false, the text box is editable when no DataSource is specified.
49 >
50 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
51 >    the FBLIB environment variable. If you do not want to permit this then you
52 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
53 >    this setting.
54 >
55 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
56 >
57 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
58 >   Utf8EscapeControlChars
59 >
60 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
61 >
62 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
63 > all previous copies of the IBX source code tree before installing this release.
64 >
65 > The IBX packages used by most users have not changed, with one exception. The
66 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
67 > to use the IBServices unit in your applications, please add the iblegacyServices
68 > to the list of dependencies. To do this, open the Project Inspector and select
69 > Add->New Requirement and select "ibLegacyServices" from the list of available
70 > packages.
71 >
72 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
73 >   the IBServices unit providing what is intended to be a clearer and easier to
74 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
75 >   more information and the guide to "Firebird Service Management Using IBX".
76 >   As indicated above, the legacy services components are still available and
77 >   provided in a separate package. There is no need to update working applications
78 >   using the older versions except for an additional package dependency.
79 >
80 > 2. The IBX packages and source code tree have been re-organised in an attempt to
81 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
82 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
83 >   new set of IBX packages.
84 >
85 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
86 >   updated to use the new Services API components.
87 >
88 > 4. The iblocal package has been updated to use the new Services API components.
89 >
90 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
91 >   TIBXSecurityService. It had been wrongly classified in the previous version
92 >   as a per database configuration item. It is global to a server and hence
93 >   correctly positioned as part of the Security Package. In the DBAdmin example,
94 >   the setting has moved to the mappings page.
95 >
96 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
97 >   are ignored.
98 >
99 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
100 >   closed before the database is dropped. Before and After Disconnect event handlers
101 >   are also fired.
102 >
103 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
104 >   is started and not just the first time.
105 >
106 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
107 >   depenendency with comp type.
108 >
109 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
110 >
111 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
112 >    then this is recognised and not ignored.
113 >
114 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
115 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
116 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
117 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
118 >
119 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
120 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
121 >    counters for the select query. Note: stats accumulate after each fetch from
122 >    the database. To get total query cost after open, call the "Last" method
123 >    and then GetPerfStatistics.
124 >
125 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
126 >
127 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
128 >    in parenthesises.
129 >
130 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
131 >    SQL identifiers are always delimited by double quotes. If false, then they are
132 >    only delimited if the identifier is a reserved word, contains lower case or special
133 >    characters. Set this property to true to retain previous behaviour.
134 >
135 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
136 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
137 >
138 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
139 >       property MasterDetailDelay: integer {defaults to zero}
140 >
141 >    When non-zero and the dataset is a detail table referencing a master table
142 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
143 >    then a synchronisation delay is added (in milliseconds) between the master
144 >    row changing and the detail dataset being re-opened. If the master dataset
145 >    is scrolled before the delay expires then the delay is reset. This can be used
146 >    to avoid performance overheads when scrolling through a large master dataset.
147 >
148 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
149 >    chreads unit must be included in your project. TTimer is not used in order
150 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
151 >
152 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
153 >    with Extract Option eoDatabase.
154 >
155 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
156 >    When a deLayoutChanged event is reported on the ListSource dataset, the
157 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
158 >    relationship with the control's datasource (master).
159 >
160 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
161 >
162 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
163 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
164 >
165 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
166 >    DDL (Firebird 3 and later only).
167 >
168 > 22. TIBLookupComboBox Autocomplete Fixes:
169 >    i. Only appended text is now selected after autocomplete.
170 >    ii. Uppercase keys no longer ignored for autocomplete.
171 >    iii. Retain Prefix case is now honoured correctly.
172 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
173 >        before autocomplete performed. i.e. behaviour now the same as when
174 >        no DataSource assigned.
175 >
176 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
177 >    between SQL statements.
178 >
179 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
180 >    ObjectNames are converted to upper case before matching against metadata object
181 >    names, unless the objectname is delimited by double quotes, in which case, the
182 >    double quotes are removed and the remaining string is used (unmodified) to match
183 >    against the metadata object name.
184 >
185 >    If true then the ObjectName is used as is without modification and matched
186 >    against the metadata object name. No attempt is made to remove double quotes.
187 >
188 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
189 >    with eoTrigger, these extract types can be used to select only Database Triggers,
190 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
191 >
192 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
193 >    statement separate character is now reset to the default (';').
194 >
195 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
196 >
197 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
198 >    a commit or reconnect statement and instead activated only when next SQL statement
199 >    is executed.
200 >
201 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
202 >
203 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
204 >    converting statement to upper case.
205 >
206 > 31. TIBExtract: metadata comments now supported. New published property
207 >    IncludeMetaDataComments (default true). If true then metadata comments included
208 >    in extracted DDL. New Extract Object member eoComments. This may be used with
209 >    ExtractObject method to list all metadata comments.
210 >
211 > 32. TIBExtract: ListObjectNames method added.
212 >
213 > 33. Updated Database component editor to support additional connection string
214 >    types.
215 >
216 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
217 >
218 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
219 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
220 > RELEASE.
221 >
222 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
223 >
224 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
225 >
226 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
227 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
228 >   information). However, this is also a very useful mechanism for returning updated computed by
229 >   column values. Values returned as a result of executing an Insert or Update statement
230 >   replace existing values in the current row for each corresponding column.
231 >
232 >   Previously, if a dataset's select query included read only (computed by) fields then
233 >   an automatic row refresh was performed after an insert or update query had been processed,
234 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
235 >   that an automatic refresh is no longer performed if an insert or update query contains
236 >   a returning clause that updates one or more fields on the current row. A full row
237 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
238 >   field values and the select query contains read only fields. Use of Insert/update
239 >   returning should be significantly more efficient than executing a refresh query.
240 >
241 >   This behaviour change is intended to be backwards compatible and there should be no need to change
242 >   existing programs, other than to improve performance by using the new capability.
243 >
244 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
245 >   they are called when the dataset row is being deleted, there is no value in
246 >   updating the current record from the query result. Instead, a new event handler
247 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
248 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
249 >   by the query. The event handler can then interrogate the query results and
250 >   perform whatever action is necessary. For example to confirm, to the user,
251 >   the deletion of a row with the returned values.
252 >
253 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
254 >   any Computed By or Identity Columns. The IBTables example has been updated to
255 >   illustrate the computation of the employee Full Name on update.
256 >
257 > 5. TIBTable: The GeneratorField property is now published.
258 >
259 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
260 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
261 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
262 >   each Identity column after the insert is executed.
263 >
264 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
265 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
266 >   Insert..Returning clause.
267 >
268 > 8. TIBGenerator: small performance improvement by not preparing query each time
269 >   a new value is generated.
270 >
271 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
272 >
273 > 10. Property editors will now sync table name to a System Table when "Include System
274 >    Tables" is selected and the query is for a System Table.
275 >
276 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
277 >    values are no longer converted to milliseconds from TDateTime and then back again
278 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
279 >
280 > 12. Property Editors handling of Stored Procedures.
281 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
282 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
283 >      query).
284 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
285 >
286 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
287 >    can be used to select a package. If non-empty, the stored procedure name is
288 >    expected to be a stored procedure defined in the specified package and the
289 >    generated SQL will be as required for a stored procedure located in a package.
290 >
291 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
292 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
293 >    which a stored procedure can be selected. With no package name selected, non-package
294 >    stored procedures are listed.
295 >
296 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
297 >    for password on reconnect.
298 >
299 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
300 >    and character set name.
301 >
302 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
303 >    DB info lookups"
304 >
305 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
306 >
307 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
308 >
309 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
310 >    parameters. This stops an exception being raised when the field cannot be
311 >    located in the record buffer.
312 >
313 > 21. Property Editors now automatically include System Tables when opened and when the query table
314 >    is a System Table.
315 >
316 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
317 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
318 >
319 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
320 >    add the SPB item isc_spb_expected_db. This names a database using
321 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
322 >    database. examples/services re-written to illustrate use of "expected_db".
323 >
324 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
325 >    This avoids truncated backups when the server returns a timeout (busy) response.
326 >
327 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
328 >
329 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
330 >    databasenames. These are respectively expanded to the local system's temp directory
331 >    (including trailing delimiter) or to a prescribed data directory (including
332 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
333 >    in the user's home directory. The hidden directory name is either the string returned
334 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
335 >    Under Windows, the directory is the same as the Data Directory as decribed
336 >    above but instead prefixed by the User's application data path. These may be
337 >    used to improve application portability for Personal Databases.
338 >
339 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
340 >    this has not worked for a long time and is not useful either. FieldDefs should be
341 >    managed using the Fields Editor as with any other dataset. To access the fields
342 >    editor for a TIBTable component, double click on the component. The fields editor
343 >    is then displayed.
344 >
345 > 28. TIBDatabaseInfo: new properties/function
346 >     * DateDBCreated (returns date/time database created)
347 >     * TransactionCount (returns no. of active transactions)
348 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
349 >     * PagesFree (Firebird 3 or later)
350 >     * PagesUsed (Firebird 3 or later)
351 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
352 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
353 >
354 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
355 >
356 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
357 >
358 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
359 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
360 >
361 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
362 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
363 >    firing during backup and restore.
364 >
365 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
366 >    for verbose output using the new property "StatisticsRequested".
367 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
368 >
369 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
370 >
371 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
372 >    palette. This uses the online validation feature added in Firebird 2.5. The
373 >    services's properties enable inclusion/exclusion of tables and indexes using
374 >    regular expressions. See.
375 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
376 >
377 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
378 >    option on a database.
379 >
380 > 37. TIBCustomService: Assign method implemented to allow copying of service login
381 >    context between service API components. "Detach" method now only detaches
382 >    service when last reference to the service interface detaches. Tidy up of
383 >    code for SetActive and Attach methods including password hiding.
384 >
385 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
386 >    and used to determine the auth method and protocol used for the connection.
387 >
388 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
389 >    a Create Database Statement generated by IBX.
390 >
391 > 40. All IBServices now have an additional published property "PortNo". This may
392 >    be set to a non-standard port number when necessary. If zero then the default
393 >    port number is used.
394 >
395 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
396 >    and not just the mouse.
397 >
398 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
399 >
400 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
401 >    image index and selected image index for each node to be set from a database field.
402 >
403 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
404 >    then database schema includes grants to all users. If not present then the
405 >    only user grants included are those to User PUBLIC.
406 >
407 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
408 >    and child nodes in dataset.

412 >
413 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
414 >   changes.
415 >
416 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
417 >   Bug could result in truncated multi-byte character set values.
418 >
419 > 3. Changes consequential on moving fbintf character set utility functions from
420 >   IFirebirdAPI to IAttachment.
421 >
422 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
423 >
424 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
425 >   results in autocomplete ignoring prefix text.
426 >
427 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
428 >   entering a new name into the text box.
429 >
430 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
431 >   Firebird rather than recomputing it.
432 >
433 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
434 >   screen centre. Previously some were "poDesigned" which may be inappropriate
435 >   for multi monitor desktops.
436 >
437 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
438 >
439 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
440 >    a transaction and always reset the object.
441 >
442 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
443 >
444 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
445 >
446 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
447 >    to a gbak format archive.
448 >
449 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
450 >
451 > 16. IBLocaldb: Drop database if error creating an empty database.
452 >
453 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
454 >    unless selected node not in current dataset.
455 >
456 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
457 >    to TIBCustomService, and IBlocalDB code tidy up.
458 >
459 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
460 >    behaviour due to uninitialised variable.
461 >
462 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
463 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
464 >
465 > 21. IBSQL: When Database changed ensure that all resources are freed.
466 >
467 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
468 >
469 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
470 >    * Line Wrap on SQL Token boundaries (on user command)
471 >    * auto-complete table names in drop down list of table names
472 >    * Double click on tablename or field name adds to SQL text
473 >
474 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
475 >
476 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
477 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
478 >    workaround for a problem in fpc 3.0.4 win64).
479 >
480 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
481 >
482 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
483 >
484 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
485 >
486 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
487 >   include remote system name.
488 >
489 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
490 >   tables when data included in output.
491 >
492 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
493 >   and timing information to be written to stdout. This may be used to locate
494 >   performance bottlenecks.
495 >
496 > 4. SQLParser: only call "OnChanging" event handler when value is different.
497 >
498 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
499 >
500 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
501 >   that BindFields is called when the query is next activated. Avoids FieldName
502 >   not found error.
503 >
504 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
505 >   purpose and allows the programmer to define any action they want for Update, Insert
506 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
507 >   filtering of updates, or use of statements such as Grant or Revoke instead of
508 >   normal DML. See User Manual for more information.
509 >
510 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
511 >
512 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
513 >
514 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
515 >
516 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
517 >   hexadecimal notation.
518 >
519 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
520 >   using a simple XML format.
521 >
522 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
523 >   grants to these objects.
524 >
525 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
526 >   dependency problems restoring complex databases.
527 >
528 > 7. TIBXScript: This component has been restructured to allow for the processing of
529 >   embedded XML in INSERT statements and to support interactive sources in addition
530 >   to non-interactive data sources such as files.
531 >
532 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
533 >
534 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
535 >   SET SQL DIALECT
536 >   SET TERM
537 >   SET AUTODDL
538 >   SET BAIL
539 >   SET ECHO
540 >   SET COUNT
541 >   SET STATS
542 >   SET NAMES <character set>
543 >
544 > 10. IBVersion unit added to hold current IBX Version Number information.
545 >
546 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
547 >    and domain definitions.
548 >
549 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
550 >    fully supported.
551 >
552 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
553 >
554 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
555 >
556 > IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
557 >
558 > See also doc/IBX4LazarusGuide.pdf for important information on
559 > upgrading to IBX2.
560 >
561 > 1. Size property of TIBStringField is now the width in characters of the field
562 >   and not the byte length. This applies only to multi-byte character sets such
563 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
564 >   code is not recognised as a bug and hence this change to align the behaviour.
565 >   The TStringField change is expected in fpc 3.2.0.
566 >
567 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
568 >   true (default) then Size property value saved in the lfm is ignored. Size is
569 >   always set from the dynamic information read from the database. It is unclear
570 >   why anyone would want to override this and set Size to false.
571 >
572 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
573 >   block.
574 >
575 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
576 >   exist when an attempt is made to connect to it (run time only) then an attempt
577 >   is made to create the database.
578 >
579 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
580 >   has been successfully created as a result of a call to CreateDatabase or when
581 >   creating a database after it was found not to exist.
582 >
583 > 6.  DBControlGrid: a race condition could result in the wrong row image being
584 >    written to the cache. This has been avoided by a trip round the message
585 >    loop before rendering the row image.
586 >
587 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
588 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
589 >    known to risk corrupt rendering of row images when the control is first
590 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
591 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
592 >
593 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
594 >    a TDateEdit control located on an editor panel.
595 >
596 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
597 >
598 > 10. DBControlGrid: Removed memory leak when updating rows.
599 >
600 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
601 >
602 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
603 >
604 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
605 >   when target codepage is CP_NONE. This is a workaround for
606 >   http://bugs.freepascal.org/view.php?id=30622.
607 >
608 > 2. DBLog option removed from TIBStatisticalService - not supported by server
609 >   since Firebird 1.5.
610 >
611 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
612 >   similar.
613 >
614 > 4. IBCodePage: updated mapping between codepages and character id.
615 >
616 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
617 >   Firebird. Character sets with a char width of two are not UTF16.
618 >
619 > 6. Strings received from the database are now always transliterated into UTF8
620 >   regardless of the database character set or connection character set. This
621 >   is for compatibility with the LCL.
622 >
623 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
624 >
625 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
626 >   read in an entire blob just to get the size of the blob. General performance
627 >   improvement when opening datasets containing blobs.
628 >
629 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
630 >
631 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
632 >   is now used.
633 >
634 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
635 >   determined.
636 >
637 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
638 >
639 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
640 >   lazarus 1.6.0
641 >
642 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
643 >   compilation error.
644 >
645 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
646 >
647 > 1. No character set specified for connection: when a text blob is retrieved, the
648 >  character set is determined by looking up the native character set using then
649 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
650 >  set as the connection.
651 >
652 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
653 >   for Login Dialog returing a change to the database path.
654 >
655 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
656 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
657 >   entered value to be saved on a project specific basis (design time only).
658 >
659 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
660 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
661 >   Otherwise, it sets the column text to the selected ListField Value.
662 >
663 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
664 >   column width.
665 >
666 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
667 >   and a case insensitive search is requested.
668 >
669 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
670 >   or column ListSource.
671 >
672 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
673 >   unprepare) when closing and the text has not changed.
674 >
675 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
676 >   Less likely to cause a cursor re-use error on Windows.
677 >
678 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
679 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
680 >
681 > 11. TIBTreeView: Guard against nil destination on record changed
682 >
683 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
684 >    string type with the code page set to reflect the returned field encoding after
685 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
686 >    earlier versions.
687 >
688 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
689 >    will now result in transliteration to the code page specified for the Firebird driver
690 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
691 >
692 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
693 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
694 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
695 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
696 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
697 >    the GETACP is used to determine the Windows code page.
698 >
699 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
700 >    name used as the lc_ctype when the database was opened. Only valid while the
701 >    Database is connected.
702 >
703 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
704 >    id that corresponds to the DefaultCharSetName.
705 >
706 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
707 >
708 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
709 >   path is given and database attach fails due to access permission issues on the
710 >   temp directory or security database, then the attach is retried with "localhost:"
711 >   prefixing the databasename. This should avoid problems when the database has to
712 >   be accessed by a local (e.g. classic) server and libfbembed is used.
713 >
714 > 2. Windows: revised search order for Firebird DLL:
715 >     i.   The Firebird Embedded Server in the application Directory.
716 >     ii.  If the FIREBIRD environment variable is set then the directory this
717 >          points to is searched for the FB Client DLL and then then underlying
718 >          "bin" directory.
719 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
720 >          is used to locate the Firebird installation directory and the underlying
721 >          "bin" directory is searched for the FB Client DLL.
722 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
723 >          are searched for the FB Client DLL.
724 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
725 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
726 >
727 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
728 >   See doc/readme.scriptengine and example applications.
729 >
730 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
731 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
732 >   See dpc/readme.localdatabase and example applications.
733 >
734 > 5. IBDynamicGrid: Reordering on column header click should now also work for
735 >   dynamic columns.
736 >
737 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
738 >   between incrementing/decrementing the lock count and signalling the event.
739 >
740 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
741 >
742 > 1.3.2 was never formally released and only made available as beta copies.
743 >
744 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
745 >
746 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
747 >
748 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
749 >
750 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
751 >   i.e. when it is a calculated field
752 >
753 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
754 >   This problem was due to a race condition between recalculating row heights and
755 >   determining which row was selected by the mouse click. The row height calculation
756 >   is now deferred by an extra trip round the message loop allowing the row to
757 >   be always calculated on the current grid layout rather than risking it being
758 >   calculated on the grid layout after the expanded row has been shrunk.
759 >
760 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
761 >   Windows.
762 >
763 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
764 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
765 >   to be determined at runtime. See doc/readme.charactersets.html.
766 >
767 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
768 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
769 >
770 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
771 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
772 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
773 >
774 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
775 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
776 >   implies no truncation.
777 >
778 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
779 >
780 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
781 >   (avoids "Not in Edit Mode" error).
782 >
783 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
784 >
785 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
786 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
787 >
788 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
789 >
790 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
791 >
792 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
793 >
794 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
795 >
796 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
797 >
798 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
799 >
800 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
801 >     problem with row size when exception is called.
802 >
803 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
804 >
805 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
806 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
807 >
808 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
809 >     keyed in i.e. when autocomplete not performed
810 >
811 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
812 >     console mode applications with all LCL required functions (builtin dialogs and
813 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
814 >     not included in your project, IBX should compile and link with a console mode program.
815 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
816 >     console mode application or the IDE will automatically assume that your
817 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
818 >
819 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
820 >     to use the built in dialogs and cursor management. IBDialogs is
821 >     included by default if "ibexpress" is in your project source's "uses" clause.
822 >     This should be the case for all projects created through the IDE. This is why
823 >     you do not want to add the ibexpress package to console mode applications. The
824 >     ibexpressconsolemode package has been created to allow console mode programs
825 >     to avoid adding LCL dependencies when using IBX, while still having the
826 >     unit search paths set up correctly.
827 >
828 >     Existing users should check to ensure that the "ibexpress" unit is included in
829 >     each project's source file (*.lpr).
830 >
831 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
832 >     exists, you have to first open the package in the IDE and then close it. This
833 >     adds it to the most recently accessed packages list. To make it permanently
