2 >
3 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 >    number of UTF8 characters exceeds the string size then string is truncated
5 >    to the maximum string size. This is  usually a problem with fixed width columns
6 >    right padded with white space.
7 >
8 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 >    If SQLFiltered is set then when a dataset is opened, each line in the
10 >    SQLFilterParams property is assumed to be a SQL condition clause and
11 >    ANDed into the Where clause of the SQL Select statement provided as a
12 >    dataset property. Each such SQL condition thus acts as an additional filter
13 >    on the dataset. (Not yet tested)
14 >
15 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 >    side filters).
17 >
18 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
19 >
20 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
21 >    not SQL Identifiers are now supported.
22 >
23 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
24 >    passed to the Firebird engine for execution.
25 >
26 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
27 >    is made to scroll back.
28 >
29 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
30 >
31 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
32 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
33 >
34 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
35 >   validated. If no match is found in the list of field names and the database has
36 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
37 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
38 >
39 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
40 >   with fpc 3.2.
41 >
42 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
43 >
44 >
45 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
46 >   and is used to override the default settings in the client side "firebird.conf" This
47 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
48 >   Each line of the string list should be a setting in the same format as "firebird.conf".
49 >   For example "WireCompression = true" in order to request wire compression on the client side.
50 >
51 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
52 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
53 >   also require a compatible setting in the server side "firebird.conf". For example
54 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
55 >   compression to be used.
56 >
57 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
58 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
59 >   ibx/examples/dbinfo for examples of how to display this information.
60 >
61 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
62 >   is a "convenience" property. If set the "WireCompression=true" is added to the
63 >   ConfigOverrides. If unchecked then this setting is removed.
64 >
65 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
66 >   not "INT64".
67 >
68 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
69 >   These are:
70 >    property TimestampFormat: string;
71 >    property DateFormat: string;
72 >    property TimeFormat: string;
73 >
74 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
75 >   DATETIME and TIME. The format strings use the standard FPC date/time format
76 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
77 >
78 >   If any of the above properties are set to an empty string, then the locale default
79 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
80 >   locale default is extended by appending '.zzz' to include milliseconds.
81 >
82 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
83 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
84 >
85 > 5. New published property for TIBCSVDataOut:
86 >     property QuoteStrings: boolean (default true)
87 >
88 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
89 >   used to delimit each and every string in the output.
90 >
91 > 6. New published properties for TIBCSVDataOut:
92 >    property FieldSeparator: string;
93 >    property HeaderSeparator: string;
94 >
95 >   Respectively, these provide the separator character(s) used to separate fields
96 >   in data and header rows. Both default to ','.
97 >
98 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
99 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
100 >    property OnFormatTextString;
101 >
102 >   This event handler can be used to process text strings before they are included
103 >   in the output e.g. to replace unprintable characters with alternative strings.
104 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
105 >
106 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
107 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
108 >   and without raising and exception if it does not.
109 >
110 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
111 >   consistency with SQL queries.
112 >
113 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
114 >    When true, SQL statement parameter names are parsed case sensitive. Note for
115 >    TIBDataSet only applies to Select query.
116 >
117 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
118 >    an IDE exception.
119 >
120 > 12. LocalDBSupport: initial database creation should now work correctly
121 >    when the schema source is an sql file.
122 >
123 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
124 >    when defined, this handler will be called by the internal TIBXScript during
125 >    initial database creation when the schema source is an sql file and may be used
126 >    to provide a visual indication of progress in console mode.
127 >
128 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
129 >    to true while a new local database is being created and its schema populated.
130 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
131 >    when the database is disconnected/connected during the create DB procedure.
132 >
133 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
134 >    are now always ignored and replaced by the user name and password provided as
135 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
136 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
137 >    completely ignored if this property is true.
138 >
139 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
140 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
141 >    ImageIndex and SelectImageIndex values on AddNode.
142 >
143 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
144 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
145 >    the same database connection.
146 >
147 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
148 >    if provided, this should be an conditional SQL expression suitable for
149 >    including in an SQL Select statement "where" clause. If non-empty and the
150 >    "Filtered" property is true then the SQL expression provided as the value of
151 >    the "Filter" property is "ANDed" with any existing condition statement
152 >    in the SQL statement's "Where" clause.
153 >
154 >    If the "Filter" property is set at run time, the "Filtered" property is true
155 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
156 >
157 >    The "Filter" condition may include IBX style parameters. In which case, their
158 >    value must be set by the dataset's "OnBeforeOpen" event handler.
159 >
160 >    This is a public property for TIBDataSet and TIBQuery query and intended for
161 >    use at run time.
162 >
163 >    Note: The property is a published property of TIBTable. The TIBTable functionality
164 >    is unaffected by this change.
165 >
166 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
167 >
168 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
169 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
170 >   mode apps.
171 >
172 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
173 >   statement. This avoids problems if "Execute Block" is used as the Query.
174 >
175 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
176 >   internal SQL tokeniser routines.
177 >
178 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
179 >   as a select statement, with or without CTEs.
180 >
181 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
182 >
183 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
184 >   internal SQL tokeniser routines.
185 >
186 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
187 >    being raised for valid set statements processed by a data formatter.
188 >
189 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
190 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
191 >   the path of the Firebird Library used by the database/services connection.
192 >
193 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
194 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
195 >   services connection.
196 >
197 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
198 >   or param name is not a valid SQL identifier.
199 >
200 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
201 >    view of whether the text box should be editable when no DataSource is specified.
202 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
203 >    ReadOnly is false, the text box is editable when no DataSource is specified.
204 >
205 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
206 >    the FBLIB environment variable. If you do not want to permit this then you
207 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
208 >    this setting.
209 >
210 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
211 >
212 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
213 >   Utf8EscapeControlChars
214 >
215 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
216 >
217 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
218 > all previous copies of the IBX source code tree before installing this release.
219 >
220 > The IBX packages used by most users have not changed, with one exception. The
221 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
222 > to use the IBServices unit in your applications, please add the iblegacyServices
223 > to the list of dependencies. To do this, open the Project Inspector and select
224 > Add->New Requirement and select "ibLegacyServices" from the list of available
225 > packages.
226 >
227 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
228 >   the IBServices unit providing what is intended to be a clearer and easier to
229 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
230 >   more information and the guide to "Firebird Service Management Using IBX".
231 >   As indicated above, the legacy services components are still available and
232 >   provided in a separate package. There is no need to update working applications
233 >   using the older versions except for an additional package dependency.
234 >
235 > 2. The IBX packages and source code tree have been re-organised in an attempt to
236 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
237 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
238 >   new set of IBX packages.
239 >
240 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
241 >   updated to use the new Services API components.
242 >
243 > 4. The iblocal package has been updated to use the new Services API components.
244 >
245 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
246 >   TIBXSecurityService. It had been wrongly classified in the previous version
247 >   as a per database configuration item. It is global to a server and hence
248 >   correctly positioned as part of the Security Package. In the DBAdmin example,
249 >   the setting has moved to the mappings page.
250 >
251 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
252 >   are ignored.
253 >
254 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
255 >   closed before the database is dropped. Before and After Disconnect event handlers
256 >   are also fired.
257 >
258 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
259 >   is started and not just the first time.
260 >
261 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
262 >   depenendency with comp type.
263 >
264 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
265 >
266 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
267 >    then this is recognised and not ignored.
268 >
269 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
270 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
271 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
272 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
273 >
274 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
275 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
276 >    counters for the select query. Note: stats accumulate after each fetch from
277 >    the database. To get total query cost after open, call the "Last" method
278 >    and then GetPerfStatistics.
279 >
280 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
281 >
282 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
283 >    in parenthesises.
284 >
285 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
286 >    SQL identifiers are always delimited by double quotes. If false, then they are
287 >    only delimited if the identifier is a reserved word, contains lower case or special
288 >    characters. Set this property to true to retain previous behaviour.
289 >
290 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
291 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
292 >
293 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
294 >       property MasterDetailDelay: integer {defaults to zero}
295 >
296 >    When non-zero and the dataset is a detail table referencing a master table
297 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
298 >    then a synchronisation delay is added (in milliseconds) between the master
299 >    row changing and the detail dataset being re-opened. If the master dataset
300 >    is scrolled before the delay expires then the delay is reset. This can be used
301 >    to avoid performance overheads when scrolling through a large master dataset.
302 >
303 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
304 >    chreads unit must be included in your project. TTimer is not used in order
305 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
306 >
307 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
308 >    with Extract Option eoDatabase.
309 >
310 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
311 >    When a deLayoutChanged event is reported on the ListSource dataset, the
312 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
313 >    relationship with the control's datasource (master).
314 >
315 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
316 >
317 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
318 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
319 >
320 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
321 >    DDL (Firebird 3 and later only).
322 >
323 > 22. TIBLookupComboBox Autocomplete Fixes:
324 >    i. Only appended text is now selected after autocomplete.
325 >    ii. Uppercase keys no longer ignored for autocomplete.
326 >    iii. Retain Prefix case is now honoured correctly.
327 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
328 >        before autocomplete performed. i.e. behaviour now the same as when
329 >        no DataSource assigned.
330 >
331 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
332 >    between SQL statements.
333 >
334 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
335 >    ObjectNames are converted to upper case before matching against metadata object
336 >    names, unless the objectname is delimited by double quotes, in which case, the
337 >    double quotes are removed and the remaining string is used (unmodified) to match
338 >    against the metadata object name.
339 >
340 >    If true then the ObjectName is used as is without modification and matched
341 >    against the metadata object name. No attempt is made to remove double quotes.
342 >
343 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
344 >    with eoTrigger, these extract types can be used to select only Database Triggers,
345 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
346 >
347 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
348 >    statement separate character is now reset to the default (';').
349 >
350 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
351 >
352 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
353 >    a commit or reconnect statement and instead activated only when next SQL statement
354 >    is executed.
355 >
356 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
357 >
358 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
359 >    converting statement to upper case.
360 >
361 > 31. TIBExtract: metadata comments now supported. New published property
362 >    IncludeMetaDataComments (default true). If true then metadata comments included
363 >    in extracted DDL. New Extract Object member eoComments. This may be used with
364 >    ExtractObject method to list all metadata comments.
365 >
366 > 32. TIBExtract: ListObjectNames method added.
367 >
368 > 33. Updated Database component editor to support additional connection string
369 >    types.
370 >
371 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
372 >
373 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
374 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
375 > RELEASE.
376 >
377 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
378 >
379 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
380 >
381 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
382 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
383 >   information). However, this is also a very useful mechanism for returning updated computed by
384 >   column values. Values returned as a result of executing an Insert or Update statement
385 >   replace existing values in the current row for each corresponding column.
386 >
387 >   Previously, if a dataset's select query included read only (computed by) fields then
388 >   an automatic row refresh was performed after an insert or update query had been processed,
389 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
390 >   that an automatic refresh is no longer performed if an insert or update query contains
391 >   a returning clause that updates one or more fields on the current row. A full row
392 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
393 >   field values and the select query contains read only fields. Use of Insert/update
394 >   returning should be significantly more efficient than executing a refresh query.
395 >
396 >   This behaviour change is intended to be backwards compatible and there should be no need to change
397 >   existing programs, other than to improve performance by using the new capability.
398 >
399 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
400 >   they are called when the dataset row is being deleted, there is no value in
401 >   updating the current record from the query result. Instead, a new event handler
402 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
403 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
404 >   by the query. The event handler can then interrogate the query results and
405 >   perform whatever action is necessary. For example to confirm, to the user,
406 >   the deletion of a row with the returned values.
407 >
408 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
409 >   any Computed By or Identity Columns. The IBTables example has been updated to
410 >   illustrate the computation of the employee Full Name on update.
411 >
412 > 5. TIBTable: The GeneratorField property is now published.
413 >
414 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
415 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
416 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
417 >   each Identity column after the insert is executed.
418 >
419 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
420 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
421 >   Insert..Returning clause.
422 >
423 > 8. TIBGenerator: small performance improvement by not preparing query each time
424 >   a new value is generated.
425 >
426 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
427 >
428 > 10. Property editors will now sync table name to a System Table when "Include System
429 >    Tables" is selected and the query is for a System Table.
430 >
431 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
432 >    values are no longer converted to milliseconds from TDateTime and then back again
433 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
434 >
435 > 12. Property Editors handling of Stored Procedures.
436 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
437 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
438 >      query).
439 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
440 >
441 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
442 >    can be used to select a package. If non-empty, the stored procedure name is
443 >    expected to be a stored procedure defined in the specified package and the
444 >    generated SQL will be as required for a stored procedure located in a package.
445 >
446 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
447 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
448 >    which a stored procedure can be selected. With no package name selected, non-package
449 >    stored procedures are listed.
450 >
451 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
452 >    for password on reconnect.
453 >
454 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
455 >    and character set name.
456 >
457 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
458 >    DB info lookups"
459 >
460 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
461 >
462 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
463 >
464 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
465 >    parameters. This stops an exception being raised when the field cannot be
466 >    located in the record buffer.
467 >
468 > 21. Property Editors now automatically include System Tables when opened and when the query table
469 >    is a System Table.
470 >
471 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
472 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
473 >
474 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
475 >    add the SPB item isc_spb_expected_db. This names a database using
476 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
477 >    database. examples/services re-written to illustrate use of "expected_db".
478 >
479 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
480 >    This avoids truncated backups when the server returns a timeout (busy) response.
481 >
482 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
483 >
484 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
485 >    databasenames. These are respectively expanded to the local system's temp directory
486 >    (including trailing delimiter) or to a prescribed data directory (including
487 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
488 >    in the user's home directory. The hidden directory name is either the string returned
489 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
490 >    Under Windows, the directory is the same as the Data Directory as decribed
491 >    above but instead prefixed by the User's application data path. These may be
492 >    used to improve application portability for Personal Databases.
493 >
494 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
495 >    this has not worked for a long time and is not useful either. FieldDefs should be
496 >    managed using the Fields Editor as with any other dataset. To access the fields
497 >    editor for a TIBTable component, double click on the component. The fields editor
498 >    is then displayed.
499 >
500 > 28. TIBDatabaseInfo: new properties/function
501 >     * DateDBCreated (returns date/time database created)
502 >     * TransactionCount (returns no. of active transactions)
503 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
504 >     * PagesFree (Firebird 3 or later)
505 >     * PagesUsed (Firebird 3 or later)
506 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
507 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
508 >
509 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
510 >
511 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
512 >
513 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
514 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
515 >
516 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
517 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
518 >    firing during backup and restore.
519 >
520 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
521 >    for verbose output using the new property "StatisticsRequested".
522 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
523 >
524 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
525 >
526 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
527 >    palette. This uses the online validation feature added in Firebird 2.5. The
528 >    services's properties enable inclusion/exclusion of tables and indexes using
529 >    regular expressions. See.
530 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
531 >
532 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
533 >    option on a database.
534 >
535 > 37. TIBCustomService: Assign method implemented to allow copying of service login
536 >    context between service API components. "Detach" method now only detaches
537 >    service when last reference to the service interface detaches. Tidy up of
538 >    code for SetActive and Attach methods including password hiding.
539 >
540 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
541 >    and used to determine the auth method and protocol used for the connection.
542 >
543 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
544 >    a Create Database Statement generated by IBX.
545 >
546 > 40. All IBServices now have an additional published property "PortNo". This may
547 >    be set to a non-standard port number when necessary. If zero then the default
548 >    port number is used.
549 >
550 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
551 >    and not just the mouse.
552 >
553 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
554 >
555 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
556 >    image index and selected image index for each node to be set from a database field.
557 >
558 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
559 >    then database schema includes grants to all users. If not present then the
560 >    only user grants included are those to User PUBLIC.
561 >
562 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
563 >    and child nodes in dataset.
