26 >
27 >
28 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
29 >   and is used to override the default settings in the client side "firebird.conf" This
30 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
31 >   Each line of the string list should be a setting in the same format as "firebird.conf".
32 >   For example "WireCompression = true" in order to request wire compression on the client side.
33 >
34 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
35 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
36 >   also require a compatible setting in the server side "firebird.conf". For example
37 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
38 >   compression to be used.
39 >
40 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
41 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
42 >   ibx/examples/dbinfo for examples of how to display this information.
43 >
44 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
45 >   is a "convenience" property. If set the "WireCompression=true" is added to the
46 >   ConfigOverrides. If unchecked then this setting is removed.
47 >
48 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
49 >   not "INT64".
50 >
51 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
52 >   These are:
53 >    property TimestampFormat: string;
54 >    property DateFormat: string;
55 >    property TimeFormat: string;
56 >
57 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
58 >   DATETIME and TIME. The format strings use the standard FPC date/time format
59 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
60 >
61 >   If any of the above properties are set to an empty string, then the locale default
62 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
63 >   locale default is extended by appending '.zzz' to include milliseconds.
64 >
65 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
66 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
67 >
68 > 5. New published property for TIBCSVDataOut:
69 >     property QuoteStrings: boolean (default true)
70 >
71 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
72 >   used to delimit each and every string in the output.
73 >
74 > 6. New published properties for TIBCSVDataOut:
75 >    property FieldSeparator: string;
76 >    property HeaderSeparator: string;
77 >
78 >   Respectively, these provide the separator character(s) used to separate fields
79 >   in data and header rows. Both default to ','.
80 >
81 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
82 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
83 >    property OnFormatTextString;
84 >
85 >   This event handler can be used to process text strings before they are included
86 >   in the output e.g. to replace unprintable characters with alternative strings.
87 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
88 >
89 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
90 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
91 >   and without raising and exception if it does not.
92 >
93 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
94 >   consistency with SQL queries.
95 >
96 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
97 >    When true, SQL statement parameter names are parsed case sensitive. Note for
98 >    TIBDataSet only applies to Select query.
99 >
100 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
101 >    an IDE exception.
102 >
103 > 12. LocalDBSupport: initial database creation should now work correctly
104 >    when the schema source is an sql file.
105 >
106 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
107 >    when defined, this handler will be called by the internal TIBXScript during
108 >    initial database creation when the schema source is an sql file and may be used
109 >    to provide a visual indication of progress in console mode.
110 >
111 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
112 >    to true while a new local database is being created and its schema populated.
113 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
114 >    when the database is disconnected/connected during the create DB procedure.
115 >
116 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
117 >    are now always ignored and replaced by the user name and password provided as
118 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
119 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
120 >    completely ignored if this property is true.
121 >
122 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
123 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
124 >    ImageIndex and SelectImageIndex values on AddNode.
125 >
126 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
127 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
128 >    the same database connection.
129 >
130 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
131 >    if provided, this should be an conditional SQL expression suitable for
132 >    including in an SQL Select statement "where" clause. If non-empty and the
133 >    "Filtered" property is true then the SQL expression provided as the value of
134 >    the "Filter" property is "ANDed" with any existing condition statement
135 >    in the SQL statement's "Where" clause.
136 >
137 >    If the "Filter" property is set at run time, the "Filtered" property is true
138 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
139 >
140 >    The "Filter" condition may include IBX style parameters. In which case, their
141 >    value must be set by the dataset's "OnBeforeOpen" event handler.
142 >
143 >    This is a public property for TIBDataSet and TIBQuery query and intended for
144 >    use at run time.
145 >
146 >    Note: The property is a published property of TIBTable. The TIBTable functionality
147 >    is unaffected by this change.
148 >
149 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
150 >
151 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
152 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
153 >   mode apps.
154 >
155 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
156 >   statement. This avoids problems if "Execute Block" is used as the Query.
157 >
158 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
159 >   internal SQL tokeniser routines.
160 >
161 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
162 >   as a select statement, with or without CTEs.
163 >
164 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
165 >
166 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
167 >   internal SQL tokeniser routines.
168 >
169 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
170 >    being raised for valid set statements processed by a data formatter.
171 >
172 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
173 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
174 >   the path of the Firebird Library used by the database/services connection.
175 >
176 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
177 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
178 >   services connection.
179 >
180 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
181 >   or param name is not a valid SQL identifier.
182 >
183 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
184 >    view of whether the text box should be editable when no DataSource is specified.
185 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
186 >    ReadOnly is false, the text box is editable when no DataSource is specified.
187 >
188 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
189 >    the FBLIB environment variable. If you do not want to permit this then you
190 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
191 >    this setting.
192 >
193 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
194 >
195 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
196 >   Utf8EscapeControlChars
197 >
198 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
199 >
200 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
201 > all previous copies of the IBX source code tree before installing this release.
202 >
203 > The IBX packages used by most users have not changed, with one exception. The
204 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
205 > to use the IBServices unit in your applications, please add the iblegacyServices
206 > to the list of dependencies. To do this, open the Project Inspector and select
207 > Add->New Requirement and select "ibLegacyServices" from the list of available
208 > packages.
209 >
210 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
211 >   the IBServices unit providing what is intended to be a clearer and easier to
212 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
213 >   more information and the guide to "Firebird Service Management Using IBX".
214 >   As indicated above, the legacy services components are still available and
215 >   provided in a separate package. There is no need to update working applications
216 >   using the older versions except for an additional package dependency.
217 >
218 > 2. The IBX packages and source code tree have been re-organised in an attempt to
219 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
220 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
221 >   new set of IBX packages.
222 >
223 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
224 >   updated to use the new Services API components.
225 >
226 > 4. The iblocal package has been updated to use the new Services API components.
227 >
228 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
229 >   TIBXSecurityService. It had been wrongly classified in the previous version
230 >   as a per database configuration item. It is global to a server and hence
231 >   correctly positioned as part of the Security Package. In the DBAdmin example,
232 >   the setting has moved to the mappings page.
233 >
234 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
235 >   are ignored.
236 >
237 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
238 >   closed before the database is dropped. Before and After Disconnect event handlers
239 >   are also fired.
240 >
241 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
242 >   is started and not just the first time.
243 >
244 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
245 >   depenendency with comp type.
246 >
247 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
248 >
249 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
250 >    then this is recognised and not ignored.
251 >
252 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
253 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
254 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
255 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
256 >
257 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
258 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
259 >    counters for the select query. Note: stats accumulate after each fetch from
260 >    the database. To get total query cost after open, call the "Last" method
261 >    and then GetPerfStatistics.
262 >
263 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
264 >
265 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
266 >    in parenthesises.
267 >
268 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
269 >    SQL identifiers are always delimited by double quotes. If false, then they are
270 >    only delimited if the identifier is a reserved word, contains lower case or special
271 >    characters. Set this property to true to retain previous behaviour.
272 >
273 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
274 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
275 >
276 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
277 >       property MasterDetailDelay: integer {defaults to zero}
278 >
279 >    When non-zero and the dataset is a detail table referencing a master table
280 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
281 >    then a synchronisation delay is added (in milliseconds) between the master
282 >    row changing and the detail dataset being re-opened. If the master dataset
283 >    is scrolled before the delay expires then the delay is reset. This can be used
284 >    to avoid performance overheads when scrolling through a large master dataset.
285 >
286 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
287 >    chreads unit must be included in your project. TTimer is not used in order
288 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
289 >
290 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
291 >    with Extract Option eoDatabase.
292 >
293 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
294 >    When a deLayoutChanged event is reported on the ListSource dataset, the
295 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
296 >    relationship with the control's datasource (master).
297 >
298 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
299 >
300 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
301 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
302 >
303 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
304 >    DDL (Firebird 3 and later only).
305 >
306 > 22. TIBLookupComboBox Autocomplete Fixes:
307 >    i. Only appended text is now selected after autocomplete.
308 >    ii. Uppercase keys no longer ignored for autocomplete.
309 >    iii. Retain Prefix case is now honoured correctly.
310 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
311 >        before autocomplete performed. i.e. behaviour now the same as when
312 >        no DataSource assigned.
313 >
314 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
315 >    between SQL statements.
316 >
317 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
318 >    ObjectNames are converted to upper case before matching against metadata object
319 >    names, unless the objectname is delimited by double quotes, in which case, the
320 >    double quotes are removed and the remaining string is used (unmodified) to match
321 >    against the metadata object name.
322 >
323 >    If true then the ObjectName is used as is without modification and matched
324 >    against the metadata object name. No attempt is made to remove double quotes.
325 >
326 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
327 >    with eoTrigger, these extract types can be used to select only Database Triggers,
328 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
329 >
330 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
331 >    statement separate character is now reset to the default (';').
332 >
333 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
334 >
335 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
336 >    a commit or reconnect statement and instead activated only when next SQL statement
337 >    is executed.
338 >
339 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
340 >
341 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
342 >    converting statement to upper case.
343 >
344 > 31. TIBExtract: metadata comments now supported. New published property
345 >    IncludeMetaDataComments (default true). If true then metadata comments included
346 >    in extracted DDL. New Extract Object member eoComments. This may be used with
347 >    ExtractObject method to list all metadata comments.
348 >
349 > 32. TIBExtract: ListObjectNames method added.
350 >
351 > 33. Updated Database component editor to support additional connection string
352 >    types.
353 >
354 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
355 >
356 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
357 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
358 > RELEASE.
359 >
360 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
361 >
362 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
363 >
364 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
365 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
366 >   information). However, this is also a very useful mechanism for returning updated computed by
367 >   column values. Values returned as a result of executing an Insert or Update statement
368 >   replace existing values in the current row for each corresponding column.
369 >
370 >   Previously, if a dataset's select query included read only (computed by) fields then
371 >   an automatic row refresh was performed after an insert or update query had been processed,
372 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
373 >   that an automatic refresh is no longer performed if an insert or update query contains
374 >   a returning clause that updates one or more fields on the current row. A full row
375 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
376 >   field values and the select query contains read only fields. Use of Insert/update
377 >   returning should be significantly more efficient than executing a refresh query.
378 >
379 >   This behaviour change is intended to be backwards compatible and there should be no need to change
380 >   existing programs, other than to improve performance by using the new capability.
381 >
382 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
383 >   they are called when the dataset row is being deleted, there is no value in
384 >   updating the current record from the query result. Instead, a new event handler
385 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
386 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
387 >   by the query. The event handler can then interrogate the query results and
388 >   perform whatever action is necessary. For example to confirm, to the user,
389 >   the deletion of a row with the returned values.
390 >
391 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
392 >   any Computed By or Identity Columns. The IBTables example has been updated to
393 >   illustrate the computation of the employee Full Name on update.
394 >
395 > 5. TIBTable: The GeneratorField property is now published.
396 >
397 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
398 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
399 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
400 >   each Identity column after the insert is executed.
401 >
402 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
403 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
404 >   Insert..Returning clause.
405 >
406 > 8. TIBGenerator: small performance improvement by not preparing query each time
407 >   a new value is generated.
408 >
409 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
410 >
411 > 10. Property editors will now sync table name to a System Table when "Include System
412 >    Tables" is selected and the query is for a System Table.
413 >
414 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
415 >    values are no longer converted to milliseconds from TDateTime and then back again
416 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
417 >
418 > 12. Property Editors handling of Stored Procedures.
419 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
420 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
421 >      query).
422 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
423 >
424 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
425 >    can be used to select a package. If non-empty, the stored procedure name is
426 >    expected to be a stored procedure defined in the specified package and the
427 >    generated SQL will be as required for a stored procedure located in a package.
428 >
429 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
430 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
431 >    which a stored procedure can be selected. With no package name selected, non-package
432 >    stored procedures are listed.
433 >
434 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
435 >    for password on reconnect.
436 >
437 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
438 >    and character set name.
439 >
440 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
441 >    DB info lookups"
442 >
443 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
444 >
445 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
446 >
447 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
448 >    parameters. This stops an exception being raised when the field cannot be
449 >    located in the record buffer.
450 >
451 > 21. Property Editors now automatically include System Tables when opened and when the query table
452 >    is a System Table.
453 >
454 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
455 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
456 >
457 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
458 >    add the SPB item isc_spb_expected_db. This names a database using
459 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
460 >    database. examples/services re-written to illustrate use of "expected_db".
461 >
462 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
463 >    This avoids truncated backups when the server returns a timeout (busy) response.
464 >
465 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
466 >
467 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
468 >    databasenames. These are respectively expanded to the local system's temp directory
469 >    (including trailing delimiter) or to a prescribed data directory (including
470 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
471 >    in the user's home directory. The hidden directory name is either the string returned
472 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
473 >    Under Windows, the directory is the same as the Data Directory as decribed
474 >    above but instead prefixed by the User's application data path. These may be
475 >    used to improve application portability for Personal Databases.
476 >
477 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
478 >    this has not worked for a long time and is not useful either. FieldDefs should be
479 >    managed using the Fields Editor as with any other dataset. To access the fields
480 >    editor for a TIBTable component, double click on the component. The fields editor
481 >    is then displayed.
482 >
483 > 28. TIBDatabaseInfo: new properties/function
484 >     * DateDBCreated (returns date/time database created)
485 >     * TransactionCount (returns no. of active transactions)
486 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
487 >     * PagesFree (Firebird 3 or later)
488 >     * PagesUsed (Firebird 3 or later)
489 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
490 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
491 >
492 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
493 >
494 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
495 >
496 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
497 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
498 >
499 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
500 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
501 >    firing during backup and restore.
502 >
503 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
504 >    for verbose output using the new property "StatisticsRequested".
505 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
506 >
507 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
508 >
509 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
510 >    palette. This uses the online validation feature added in Firebird 2.5. The
511 >    services's properties enable inclusion/exclusion of tables and indexes using
512 >    regular expressions. See.
513 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
514 >
515 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
516 >    option on a database.
517 >
518 > 37. TIBCustomService: Assign method implemented to allow copying of service login
519 >    context between service API components. "Detach" method now only detaches
520 >    service when last reference to the service interface detaches. Tidy up of
521 >    code for SetActive and Attach methods including password hiding.
522 >
523 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
524 >    and used to determine the auth method and protocol used for the connection.
525 >
526 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
527 >    a Create Database Statement generated by IBX.
528 >
529 > 40. All IBServices now have an additional published property "PortNo". This may
530 >    be set to a non-standard port number when necessary. If zero then the default
531 >    port number is used.
532 >
533 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
534 >    and not just the mouse.
535 >
536 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
537 >
538 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
539 >    image index and selected image index for each node to be set from a database field.
540 >
541 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
542 >    then database schema includes grants to all users. If not present then the
543 >    only user grants included are those to User PUBLIC.
544 >
545 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
546 >    and child nodes in dataset.

558 >   IFirebirdAPI to IAttachment.
559 >
560 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
561 >
562 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
563 >   results in autocomplete ignoring prefix text.
564 >
565 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
566 >   entering a new name into the text box.
567 >
568 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
569 >   Firebird rather than recomputing it.
570 >
571 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
572 >   screen centre. Previously some were "poDesigned" which may be inappropriate
573 >   for multi monitor desktops.

575 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
576 >
577 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
578 >    a transaction and always reset the object.

594 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
595 >    to TIBCustomService, and IBlocalDB code tidy up.
596 >
597 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
598 >    behaviour due to uninitialised variable.
599 >
600 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from

617 >
618 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
619 >
620 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

640     not found error.
641  
642 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
643 +   purpose and allows the programmer to define any action they want for Update, Insert
644 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
645 +   filtering of updates, or use of statements such as Grant or Revoke instead of
646 +   normal DML. See User Manual for more information.
