3 < 1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to
3 >
4 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
5 >   and is used to override the default settings in the client side "firebird.conf" This
6 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
7 >   Each line of the string list should be a setting in the same format as "firebird.conf".
8 >   For example "WireCompression = true" in order to request wire compression on the client side.
9 >
10 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
11 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
12 >   also require a compatible setting in the server side "firebird.conf". For example
13 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
14 >   compression to be used.
15 >
16 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
17 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
18 >   ibx/examples/dbinfo for examples of how to display this information.
19 >
20 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
21 >   is a "convenience" property. If set the "WireCompression=true" is added to the
22 >   ConfigOverrides. If unchecked then this setting is removed.
23 >
24 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
25 >   not "INT64".
26 >
27 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
28 >   These are:
29 >    property TimestampFormat: string;
30 >    property DateFormat: string;
31 >    property TimeFormat: string;
32 >
33 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
34 >   DATETIME and TIME. The format strings use the standard FPC date/time format
35 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
36 >
37 >   If any of the above properties are set to an empty string, then the locale default
38 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
39 >   locale default is extended by appending '.zzz' to include milliseconds.
40 >
41 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
42 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
43 >
44 > 5. New published property for TIBCSVDataOut:
45 >     property QuoteStrings: boolean (default true)
46 >
47 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
48 >   used to delimit each and every string in the output.
49 >
50 > 6. New published properties for TIBCSVDataOut:
51 >    property FieldSeparator: string;
52 >    property HeaderSeparator: string;
53 >
54 >   Respectively, these provide the separator character(s) used to separate fields
55 >   in data and header rows. Both default to ','.
56 >
57 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
58 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
59 >    property OnFormatTextString;
60 >
61 >   This event handler can be used to process text strings before they are included
62 >   in the output e.g. to replace unprintable characters with alternative strings.
63 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
64 >
65 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
66 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
67 >   and without raising and exception if it does not.
68 >
69 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
70 >   consistency with SQL queries.
71 >
72 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
73 >    When true, SQL statement parameter names are parsed case sensitive. Note for
74 >    TIBDataSet only applies to Select query.
75 >
76 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
77 >    an IDE exception.
78 >
79 > 12. LocalDBSupport: initial database creation should now work correctly
80 >    when the schema source is an sql file.
81 >
82 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
83 >    when defined, this handler will be called by the internal TIBXScript during
84 >    initial database creation when the schema source is an sql file and may be used
85 >    to provide a visual indication of progress in console mode.
86 >
87 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
88 >    to true while a new local database is being created and its schema populated.
89 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
90 >    when the database is disconnected/connected during the create DB procedure.
91 >
92 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
93 >    are now always ignored and replaced by the user name and password provided as
94 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
95 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
96 >    completely ignored if this property is true.
97 >
98 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
99 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
100 >    ImageIndex and SelectImageIndex values on AddNode.
101 >
102 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
103 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
104 >    the same database connection.
105 >
106 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
107 >    if provided, this should be an conditional SQL expression suitable for
108 >    including in an SQL Select statement "where" clause. If non-empty and the
109 >    "Filtered" property is true then the SQL expression provided as the value of
110 >    the "Filter" property is "ANDed" with any existing condition statement
111 >    in the SQL statement's "Where" clause.
112 >
113 >    If the "Filter" property is set at run time, the "Filtered" property is true
114 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
115 >
116 >    The "Filter" condition may include IBX style parameters. In which case, their
117 >    value must be set by the dataset's "OnBeforeOpen" event handler.
118 >
119 >    This is a public property for TIBDataSet and TIBQuery query and intended for
120 >    use at run time.
121 >
122 >    Note: The property is a published property of TIBTable. The TIBTable functionality
123 >    is unaffected by this change.
124 >
125 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
126 >
127 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
128 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
129 >   mode apps.
130 >
131 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
132 >   statement. This avoids problems if "Execute Block" is used as the Query.
133 >
134 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
135 >   internal SQL tokeniser routines.
136 >
137 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
138 >   as a select statement, with or without CTEs.
139 >
140 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
141 >
142 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
143 >   internal SQL tokeniser routines.
144 >
145 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
146 >    being raised for valid set statements processed by a data formatter.
147 >
148 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
149 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
150 >   the path of the Firebird Library used by the database/services connection.
151 >
152 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
153 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
154 >   services connection.
155 >
156 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
157 >   or param name is not a valid SQL identifier.
158 >
159 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
160 >    view of whether the text box should be editable when no DataSource is specified.
161 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
162 >    ReadOnly is false, the text box is editable when no DataSource is specified.
163 >
164 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
165 >    the FBLIB environment variable. If you do not want to permit this then you
166 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
167 >    this setting.
168 >
169 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
170 >
171 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
172 >   Utf8EscapeControlChars
173 >
174 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
175 >
176 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
177 > all previous copies of the IBX source code tree before installing this release.
178 >
179 > The IBX packages used by most users have not changed, with one exception. The
180 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
181 > to use the IBServices unit in your applications, please add the iblegacyServices
182 > to the list of dependencies. To do this, open the Project Inspector and select
183 > Add->New Requirement and select "ibLegacyServices" from the list of available
184 > packages.
185 >
186 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
187 >   the IBServices unit providing what is intended to be a clearer and easier to
188 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
189 >   more information and the guide to "Firebird Service Management Using IBX".
190 >   As indicated above, the legacy services components are still available and
191 >   provided in a separate package. There is no need to update working applications
192 >   using the older versions except for an additional package dependency.
193 >
194 > 2. The IBX packages and source code tree have been re-organised in an attempt to
195 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
196 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
197 >   new set of IBX packages.
198 >
199 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
200 >   updated to use the new Services API components.
201 >
202 > 4. The iblocal package has been updated to use the new Services API components.
203 >
204 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
205 >   TIBXSecurityService. It had been wrongly classified in the previous version
206 >   as a per database configuration item. It is global to a server and hence
207 >   correctly positioned as part of the Security Package. In the DBAdmin example,
208 >   the setting has moved to the mappings page.
209 >
210 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
211 >   are ignored.
212 >
213 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
214 >   closed before the database is dropped. Before and After Disconnect event handlers
215 >   are also fired.
216 >
217 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
218 >   is started and not just the first time.
219 >
220 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
221 >   depenendency with comp type.
222 >
223 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
224 >
225 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
226 >    then this is recognised and not ignored.
227 >
228 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
229 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
230 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
231 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
232 >
233 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
234 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
235 >    counters for the select query. Note: stats accumulate after each fetch from
236 >    the database. To get total query cost after open, call the "Last" method
237 >    and then GetPerfStatistics.
238 >
239 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
240 >
241 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
242 >    in parenthesises.
243 >
244 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
245 >    SQL identifiers are always delimited by double quotes. If false, then they are
246 >    only delimited if the identifier is a reserved word, contains lower case or special
247 >    characters. Set this property to true to retain previous behaviour.
248 >
249 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
250 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
251 >
252 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
253 >       property MasterDetailDelay: integer {defaults to zero}
254 >
255 >    When non-zero and the dataset is a detail table referencing a master table
256 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
257 >    then a synchronisation delay is added (in milliseconds) between the master
258 >    row changing and the detail dataset being re-opened. If the master dataset
259 >    is scrolled before the delay expires then the delay is reset. This can be used
260 >    to avoid performance overheads when scrolling through a large master dataset.
261 >
262 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
263 >    chreads unit must be included in your project. TTimer is not used in order
264 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
265 >
266 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
267 >    with Extract Option eoDatabase.
268 >
269 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
270 >    When a deLayoutChanged event is reported on the ListSource dataset, the
271 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
272 >    relationship with the control's datasource (master).
273 >
274 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
275 >
276 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
277 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
278 >
279 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
280 >    DDL (Firebird 3 and later only).
281 >
282 > 22. TIBLookupComboBox Autocomplete Fixes:
283 >    i. Only appended text is now selected after autocomplete.
284 >    ii. Uppercase keys no longer ignored for autocomplete.
285 >    iii. Retain Prefix case is now honoured correctly.
286 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
287 >        before autocomplete performed. i.e. behaviour now the same as when
288 >        no DataSource assigned.
289 >
290 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
291 >    between SQL statements.
292 >
293 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
294 >    ObjectNames are converted to upper case before matching against metadata object
295 >    names, unless the objectname is delimited by double quotes, in which case, the
296 >    double quotes are removed and the remaining string is used (unmodified) to match
297 >    against the metadata object name.
298 >
299 >    If true then the ObjectName is used as is without modification and matched
300 >    against the metadata object name. No attempt is made to remove double quotes.
301 >
302 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
303 >    with eoTrigger, these extract types can be used to select only Database Triggers,
304 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
305 >
306 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
307 >    statement separate character is now reset to the default (';').
308 >
309 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
310 >
311 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
312 >    a commit or reconnect statement and instead activated only when next SQL statement
313 >    is executed.
314 >
315 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
316 >
317 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
318 >    converting statement to upper case.
319 >
320 > 31. TIBExtract: metadata comments now supported. New published property
321 >    IncludeMetaDataComments (default true). If true then metadata comments included
322 >    in extracted DDL. New Extract Object member eoComments. This may be used with
323 >    ExtractObject method to list all metadata comments.
324 >
325 > 32. TIBExtract: ListObjectNames method added.
326 >
327 > 33. Updated Database component editor to support additional connection string
328 >    types.
329 >
330 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
331 >
332 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
333 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
334 > RELEASE.
335 >
336 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
337 >
338 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
339 >
340 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
341 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
342 >   information). However, this is also a very useful mechanism for returning updated computed by
343 >   column values. Values returned as a result of executing an Insert or Update statement
344 >   replace existing values in the current row for each corresponding column.
345 >
346 >   Previously, if a dataset's select query included read only (computed by) fields then
347 >   an automatic row refresh was performed after an insert or update query had been processed,
348 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
349 >   that an automatic refresh is no longer performed if an insert or update query contains
350 >   a returning clause that updates one or more fields on the current row. A full row
351 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
352 >   field values and the select query contains read only fields. Use of Insert/update
353 >   returning should be significantly more efficient than executing a refresh query.
354 >
355 >   This behaviour change is intended to be backwards compatible and there should be no need to change
356 >   existing programs, other than to improve performance by using the new capability.
357 >
358 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
359 >   they are called when the dataset row is being deleted, there is no value in
360 >   updating the current record from the query result. Instead, a new event handler
361 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
362 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
363 >   by the query. The event handler can then interrogate the query results and
364 >   perform whatever action is necessary. For example to confirm, to the user,
365 >   the deletion of a row with the returned values.
366 >
367 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
368 >   any Computed By or Identity Columns. The IBTables example has been updated to
369 >   illustrate the computation of the employee Full Name on update.
370 >
371 > 5. TIBTable: The GeneratorField property is now published.
372 >
373 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
374 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
375 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
376 >   each Identity column after the insert is executed.
377 >
378 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
379 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
380 >   Insert..Returning clause.
381 >
382 > 8. TIBGenerator: small performance improvement by not preparing query each time
383 >   a new value is generated.
384 >
385 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
386 >
387 > 10. Property editors will now sync table name to a System Table when "Include System
388 >    Tables" is selected and the query is for a System Table.
389 >
390 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
391 >    values are no longer converted to milliseconds from TDateTime and then back again
392 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
393 >
394 > 12. Property Editors handling of Stored Procedures.
395 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
396 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
397 >      query).
398 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
399 >
400 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
401 >    can be used to select a package. If non-empty, the stored procedure name is
402 >    expected to be a stored procedure defined in the specified package and the
403 >    generated SQL will be as required for a stored procedure located in a package.
404 >
405 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
406 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
407 >    which a stored procedure can be selected. With no package name selected, non-package
408 >    stored procedures are listed.
409 >
410 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
411 >    for password on reconnect.
412 >
413 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
414 >    and character set name.
415 >
416 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
417 >    DB info lookups"
418 >
419 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
420 >
421 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
422 >
423 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
424 >    parameters. This stops an exception being raised when the field cannot be
425 >    located in the record buffer.
426 >
427 > 21. Property Editors now automatically include System Tables when opened and when the query table
428 >    is a System Table.
429 >
430 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
431 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
432 >
433 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
434 >    add the SPB item isc_spb_expected_db. This names a database using
435 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
436 >    database. examples/services re-written to illustrate use of "expected_db".
437 >
438 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
439 >    This avoids truncated backups when the server returns a timeout (busy) response.
440 >
441 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
442 >
443 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
444 >    databasenames. These are respectively expanded to the local system's temp directory
445 >    (including trailing delimiter) or to a prescribed data directory (including
446 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
447 >    in the user's home directory. The hidden directory name is either the string returned
448 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
449 >    Under Windows, the directory is the same as the Data Directory as decribed
450 >    above but instead prefixed by the User's application data path. These may be
451 >    used to improve application portability for Personal Databases.
452 >
453 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
454 >    this has not worked for a long time and is not useful either. FieldDefs should be
455 >    managed using the Fields Editor as with any other dataset. To access the fields
456 >    editor for a TIBTable component, double click on the component. The fields editor
457 >    is then displayed.
458 >
459 > 28. TIBDatabaseInfo: new properties/function
460 >     * DateDBCreated (returns date/time database created)
461 >     * TransactionCount (returns no. of active transactions)
462 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
463 >     * PagesFree (Firebird 3 or later)
464 >     * PagesUsed (Firebird 3 or later)
465 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
466 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
467 >
468 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
469 >
470 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
471 >
472 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
473 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
474 >
475 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
476 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
477 >    firing during backup and restore.
478 >
479 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
480 >    for verbose output using the new property "StatisticsRequested".
481 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
482 >
483 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
484 >
485 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
486 >    palette. This uses the online validation feature added in Firebird 2.5. The
487 >    services's properties enable inclusion/exclusion of tables and indexes using
488 >    regular expressions. See.
489 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
490 >
491 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
492 >    option on a database.
493 >
494 > 37. TIBCustomService: Assign method implemented to allow copying of service login
495 >    context between service API components. "Detach" method now only detaches
496 >    service when last reference to the service interface detaches. Tidy up of
497 >    code for SetActive and Attach methods including password hiding.
498 >
499 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
500 >    and used to determine the auth method and protocol used for the connection.
501 >
502 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
503 >    a Create Database Statement generated by IBX.
504 >
505 > 40. All IBServices now have an additional published property "PortNo". This may
506 >    be set to a non-standard port number when necessary. If zero then the default
507 >    port number is used.
508 >
509 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
510 >    and not just the mouse.
511 >
512 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
513 >
514 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
515 >    image index and selected image index for each node to be set from a database field.
516 >
517 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
518 >    then database schema includes grants to all users. If not present then the
519 >    only user grants included are those to User PUBLIC.
520 >
521 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
522 >    and child nodes in dataset.

534 >   IFirebirdAPI to IAttachment.
535 >
536 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
537 >
538 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
539 >   results in autocomplete ignoring prefix text.
540 >
541 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
542 >   entering a new name into the text box.
543 >
544 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
545 >   Firebird rather than recomputing it.
546 >
547 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
548 >   screen centre. Previously some were "poDesigned" which may be inappropriate
549 >   for multi monitor desktops.

557 >
558 > 13. TIBXScript: Allow for override of database filename in Create Database statements.

569 >
570 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
571 >    to TIBCustomService, and IBlocalDB code tidy up.
572 >
573 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
574 >    behaviour due to uninitialised variable.
575 >
576 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
577 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.

595 >
596 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

612   5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
613  
614 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
615 +   that BindFields is called when the query is next activated. Avoids FieldName
616 +   not found error.

618 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
619 +   purpose and allows the programmer to define any action they want for Update, Insert
620 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
621 +   filtering of updates, or use of statements such as Grant or Revoke instead of
622 +   normal DML. See User Manual for more information.
