3 < 1. IBExtract: Identity columns - add addition check for null column for generator name.
3 > 1. Add try-..except check when initially loading library in IDE. This should
4 > ensure that IDE continues to load even when a failure occurs in IBX load
5 > library.

8 >
9 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
10 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
11 >
12 > 2. TIBSQL: Batch Update/Insert support added.
13 >
14 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
15 >   is no longer automatically converted to upper case when it is syntactically a
16 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
17 >   as CREATE PROCEDURE "iCASE".
18 >
19 >   There could be a backwards compatibility issue when the StoredProcName was entered
20 >   manually at design time. That is not selected from the drop down list. If the
21 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
22 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
23 >   ensure that the value of the StoredProcName is all upper case, unless it was
24 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
25 >   quotes).
26 >
27 >   Note that when a stored procedure name was declared delimited in double quotes,
28 >   as in the first example above, the value of the StoredProcName property must not
29 >   include the delimiters (double quotes).
30 >
31 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
32 >   upgrade.conf was not found. This replaces silently ignoring the problem.
33 >
34 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
35 >   'Version.%.3d' and is used to generate the section header names (for a given
36 >   version no.) in the upgrade.conf file.
37 >
38 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
39 >
40 > 1. -c command line option added to fbsql example program. Used to set connection
41 >   character set.
42 >
43 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
44 >
45 > 1. Firebird 4 support added.
46 >
47 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
48 >   extended precision NUMERIC fields are supported.
49 >
50 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
51 >
52 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
53 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
54 >
55 > 5. IBExtract now supports FB4 enhancements:
56 >   - new data types as above
57 >   - Identity column extensions
58 >   - Default user role
59 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
60 >   - Internal Functions
61 >
62 > 6. IBExtract: new event: OnExtractLines.
63 >
64 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
65 >
66 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
67 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
68 >
69 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
70 >   format for rendering a time zone.
71 >
72 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
73 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
74 >
75 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
76 >    IIBGUIInterface and IIBTimerInf respectively.
77 >
78 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
79 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
80 >
81 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
82 >    truncated to its fixed character width rather than being right padded with
83 >    white space to the maximum data size.
84 >
85 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
86 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
87 >    also empty.
88 >
89 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
90 >
91 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
92 >    connect string. The database name is extracted from the connect string.
93 >
94 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
95 >
96 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
97 >
98 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
99 >    not being present as required.
100 >
101 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
102 >    version that can be customised to work with other database drivers.
103 >
104 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
105 >    unnecessary CR at end of line on Unix platforms.
106 >
107 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
108 >    seconds in order to reduce risk of message loss.
109 >
110 > 23. ISQLMonitor: read and write count statistics now available via:
111 >      property TIBSQLMonitor.ReadCount;
112 >      IIBSQLMonitorHook.GetWriteCount: integer;
113 >
114 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
115 >
116 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
117 >
118 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
119 >    number of UTF8 characters exceeds the string size then string is truncated
120 >    to the maximum string size. This is  usually a problem with fixed width columns
121 >    right padded with white space.
122 >
123 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
124 >    If SQLFiltered is set then when a dataset is opened, each line in the
125 >    SQLFilterParams property is assumed to be a SQL condition clause and
126 >    ANDed into the Where clause of the SQL Select statement provided as a
127 >    dataset property. Each such SQL condition thus acts as an additional filter
128 >    on the dataset.
129 >
130 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
131 >    side filters).
132 >
133 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
134 >   text matches complete entry.
135 >
136 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
137 >   dataset are active (avoids risk of access violation if master is inactive)
138 >
139 > 6. TIBEvents: Registered property can now be set at design time even if database not open
140 >
141 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
142 >   This should prevent "spillover" of events between sessions.
143 >
144 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
145 >   This should ensure that the internal buffer is set up correctly and avoids
146 >   a duplicate initial row.
147 >
148 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
149 >   That is, the DataSize should be the field size * character set width. The
150 >   value returned by DataSize is now the same as the Dataset buffer size reserved
151 >   for the field.
152 >
153 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
154 >
155 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
156 >    and vice-versa. This may result in an exception being raised (correctly) for
157 >    older programs when using dataset fields added to a form and the database has been
158 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
159 >    In such cases, the field needs to be deleted in the IDE fields editor and then
160 >    added back in.
161 >
162 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
163 >    false if query contains only white space and not just empty.
164 >
165 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
166 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
167 >    is cancelled.
168 >
169 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
170 >    called on a null field.
171 >
172 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
173 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
174 > set.
175 >
176 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
177 >    a cached update is applied and an exception is raised.
178 >
179 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
180 >
181 > 17. Console Mode Local Database support: backup/restore should now work correctly.
182 >
183 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
184 >    possible and an exception raised.
185 >
186 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
187 >    below this version no. and upgrade not possible.
188 >
189 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
190 >
191 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
192 >    not SQL Identifiers are now supported.
193 >
194 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
195 >    passed to the Firebird engine for execution.
196 >
197 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
198 >    is made to scroll back.
199 >
200 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
201 >
202 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
203 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
204 >
205 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
206 >   validated. If no match is found in the list of field names and the database has
207 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
208 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
209 >
210 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
211 >   with fpc 3.2.
212 >
213 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
214 >
215 >
216 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
217 >   and is used to override the default settings in the client side "firebird.conf" This
218 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
219 >   Each line of the string list should be a setting in the same format as "firebird.conf".
220 >   For example "WireCompression = true" in order to request wire compression on the client side.
221 >
222 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
223 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
224 >   also require a compatible setting in the server side "firebird.conf". For example
225 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
226 >   compression to be used.
227 >
228 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
229 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
230 >   ibx/examples/dbinfo for examples of how to display this information.
231 >
232 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
233 >   is a "convenience" property. If set the "WireCompression=true" is added to the
234 >   ConfigOverrides. If unchecked then this setting is removed.
235 >
236 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
237 >   not "INT64".
238 >
239 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
240 >   These are:
241 >    property TimestampFormat: string;
242 >    property DateFormat: string;
243 >    property TimeFormat: string;
244 >
245 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
246 >   DATETIME and TIME. The format strings use the standard FPC date/time format
247 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
248 >
249 >   If any of the above properties are set to an empty string, then the locale default
250 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
251 >   locale default is extended by appending '.zzz' to include milliseconds.
252 >
253 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
254 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
255 >
256 > 5. New published property for TIBCSVDataOut:
257 >     property QuoteStrings: boolean (default true)
258 >
259 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
260 >   used to delimit each and every string in the output.
261 >
262 > 6. New published properties for TIBCSVDataOut:
263 >    property FieldSeparator: string;
264 >    property HeaderSeparator: string;
265 >
266 >   Respectively, these provide the separator character(s) used to separate fields
267 >   in data and header rows. Both default to ','.
268 >
269 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
270 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
271 >    property OnFormatTextString;
272 >
273 >   This event handler can be used to process text strings before they are included
274 >   in the output e.g. to replace unprintable characters with alternative strings.
275 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
276 >
277 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
278 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
279 >   and without raising and exception if it does not.
280 >
281 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
282 >   consistency with SQL queries.
283 >
284 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
285 >    When true, SQL statement parameter names are parsed case sensitive. Note for
286 >    TIBDataSet only applies to Select query.
287 >
288 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
289 >    an IDE exception.
290 >
291 > 12. LocalDBSupport: initial database creation should now work correctly
292 >    when the schema source is an sql file.
293 >
294 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
295 >    when defined, this handler will be called by the internal TIBXScript during
296 >    initial database creation when the schema source is an sql file and may be used
297 >    to provide a visual indication of progress in console mode.
298 >
299 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
300 >    to true while a new local database is being created and its schema populated.
301 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
302 >    when the database is disconnected/connected during the create DB procedure.
303 >
304 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
305 >    are now always ignored and replaced by the user name and password provided as
306 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
307 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
308 >    completely ignored if this property is true.
309 >
310 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
311 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
312 >    ImageIndex and SelectImageIndex values on AddNode.
313 >
314 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
315 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
316 >    the same database connection.
317 >
318 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
319 >    if provided, this should be an conditional SQL expression suitable for
320 >    including in an SQL Select statement "where" clause. If non-empty and the
321 >    "Filtered" property is true then the SQL expression provided as the value of
322 >    the "Filter" property is "ANDed" with any existing condition statement
323 >    in the SQL statement's "Where" clause.
324 >
325 >    If the "Filter" property is set at run time, the "Filtered" property is true
326 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
327 >
328 >    The "Filter" condition may include IBX style parameters. In which case, their
329 >    value must be set by the dataset's "OnBeforeOpen" event handler.
330 >
331 >    This is a public property for TIBDataSet and TIBQuery query and intended for
332 >    use at run time.
333 >
334 >    Note: The property is a published property of TIBTable. The TIBTable functionality
335 >    is unaffected by this change.
336 >
337 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
338 >
339 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
340 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
341 >   mode apps.
342 >
343 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
344 >   statement. This avoids problems if "Execute Block" is used as the Query.
345 >
346 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
347 >   internal SQL tokeniser routines.
348 >
349 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
350 >   as a select statement, with or without CTEs.
351 >
352 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
353 >
354 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
355 >   internal SQL tokeniser routines.
356 >
357 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
358 >    being raised for valid set statements processed by a data formatter.
359 >
360 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
361 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
362 >   the path of the Firebird Library used by the database/services connection.
363 >
364 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
365 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
366 >   services connection.
367 >
368 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
369 >   or param name is not a valid SQL identifier.
370 >
371 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
372 >    view of whether the text box should be editable when no DataSource is specified.
373 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
374 >    ReadOnly is false, the text box is editable when no DataSource is specified.
375 >
376 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
377 >    the FBLIB environment variable. If you do not want to permit this then you
378 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
379 >    this setting.

388 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
389 > all previous copies of the IBX source code tree before installing this release.
390 >
391 > The IBX packages used by most users have not changed, with one exception. The
392 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
393 > to use the IBServices unit in your applications, please add the iblegacyServices
394 > to the list of dependencies. To do this, open the Project Inspector and select
395 > Add->New Requirement and select "ibLegacyServices" from the list of available
396 > packages.
397 >
398 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
399 >   the IBServices unit providing what is intended to be a clearer and easier to
400 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
401 >   more information and the guide to "Firebird Service Management Using IBX".
402 >   As indicated above, the legacy services components are still available and
403 >   provided in a separate package. There is no need to update working applications
404 >   using the older versions except for an additional package dependency.
405 >
406 > 2. The IBX packages and source code tree have been re-organised in an attempt to
407 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
408 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
409 >   new set of IBX packages.
410 >
411 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
412 >   updated to use the new Services API components.
413 >
414 > 4. The iblocal package has been updated to use the new Services API components.
415 >
416 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
417 >   TIBXSecurityService. It had been wrongly classified in the previous version
418 >   as a per database configuration item. It is global to a server and hence
419 >   correctly positioned as part of the Security Package. In the DBAdmin example,

542 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
543 >
544 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
545 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
546 > RELEASE.
547 >
548 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
549 >
550 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
551  
552   2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
553     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
554 <   information). Values returned as a result of executing an Insert or Update statement
555 <   replace existing values in the current row for each corresponding column.
554 >   information). However, this is also a very useful mechanism for returning updated computed by
555 >   column values. Values returned as a result of executing an Insert or Update statement
556 >   replace existing values in the current row for each corresponding column.
557 >
558 >   Previously, if a dataset's select query included read only (computed by) fields then
559 >   an automatic row refresh was performed after an insert or update query had been processed,
560 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
561 >   that an automatic refresh is no longer performed if an insert or update query contains
562 >   a returning clause that updates one or more fields on the current row. A full row
563 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
564 >   field values and the select query contains read only fields. Use of Insert/update
565 >   returning should be significantly more efficient than executing a refresh query.
566 >
567 >   This behaviour change is intended to be backwards compatible and there should be no need to change
568 >   existing programs, other than to improve performance by using the new capability.
569  
570 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
570 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
571 >   they are called when the dataset row is being deleted, there is no value in
572 >   updating the current record from the query result. Instead, a new event handler
573 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
574 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
575 >   by the query. The event handler can then interrogate the query results and
576 >   perform whatever action is necessary. For example to confirm, to the user,
577 >   the deletion of a row with the returned values.
578 >
579 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
580 >   any Computed By or Identity Columns. The IBTables example has been updated to
581 >   illustrate the computation of the employee Full Name on update.
582 >
583 > 5. TIBTable: The GeneratorField property is now published.
584 >
585 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
586     When InsertSQL is generated, the Identity columns are not included in the list of values to
587     be inserted. A RETURNING clause is added to the insert statement to return the value of
588     each Identity column after the insert is executed.
589  
590 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
591 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
592 +   Insert..Returning clause.
593 +
594 + 8. TIBGenerator: small performance improvement by not preparing query each time
595 +   a new value is generated.
596 +
597 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
598 +
599 + 10. Property editors will now sync table name to a System Table when "Include System
600 +    Tables" is selected and the query is for a System Table.
601 +
602 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
603 +    values are no longer converted to milliseconds from TDateTime and then back again
604 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
605 +
606 + 12. Property Editors handling of Stored Procedures.
607 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
608 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
609 +      query).
610 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
611 +
612 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
613 +    can be used to select a package. If non-empty, the stored procedure name is
614 +    expected to be a stored procedure defined in the specified package and the
615 +    generated SQL will be as required for a stored procedure located in a package.
616 +
617 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
618 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
619 +    which a stored procedure can be selected. With no package name selected, non-package
620 +    stored procedures are listed.
621 +
622 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
623 +    for password on reconnect.
624 +
625 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
626 +    and character set name.
627 +
628 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
629 +    DB info lookups"
630 +
631 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
632 +
633 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
634 +
635 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
636 +    parameters. This stops an exception being raised when the field cannot be
637 +    located in the record buffer.
638 +
639 + 21. Property Editors now automatically include System Tables when opened and when the query table
640 +    is a System Table.
641 +
642 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
643 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
644 +
645 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
646 +    add the SPB item isc_spb_expected_db. This names a database using
647 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
648 +    database. examples/services re-written to illustrate use of "expected_db".
649 +
650 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
651 +    This avoids truncated backups when the server returns a timeout (busy) response.
652 +
653 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
654 +
655 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
656 +    databasenames. These are respectively expanded to the local system's temp directory
657 +    (including trailing delimiter) or to a prescribed data directory (including
658 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
659 +    in the user's home directory. The hidden directory name is either the string returned
660 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
661 +    Under Windows, the directory is the same as the Data Directory as decribed
662 +    above but instead prefixed by the User's application data path. These may be
663 +    used to improve application portability for Personal Databases.
664 +
665 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
666 +    this has not worked for a long time and is not useful either. FieldDefs should be
667 +    managed using the Fields Editor as with any other dataset. To access the fields
668 +    editor for a TIBTable component, double click on the component. The fields editor
669 +    is then displayed.
670 +
671 + 28. TIBDatabaseInfo: new properties/function
672 +     * DateDBCreated (returns date/time database created)
673 +     * TransactionCount (returns no. of active transactions)
674 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
675 +     * PagesFree (Firebird 3 or later)
676 +     * PagesUsed (Firebird 3 or later)
677 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
678 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
679 +
680 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
681 +
682 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
683 +
684 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
685 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
686 +
687 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
688 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
689 +    firing during backup and restore.
690 +
691 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
692 +    for verbose output using the new property "StatisticsRequested".
693 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
694 +
695 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
696 +
697 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
698 +    palette. This uses the online validation feature added in Firebird 2.5. The
699 +    services's properties enable inclusion/exclusion of tables and indexes using
700 +    regular expressions. See.
701 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
702 +
703 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
704 +    option on a database.
705 +
706 + 37. TIBCustomService: Assign method implemented to allow copying of service login
707 +    context between service API components. "Detach" method now only detaches
708 +    service when last reference to the service interface detaches. Tidy up of
709 +    code for SetActive and Attach methods including password hiding.
710 +
711 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
712 +    and used to determine the auth method and protocol used for the connection.
713 +
714 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
715 +    a Create Database Statement generated by IBX.
716 +
717 + 40. All IBServices now have an additional published property "PortNo". This may
718 +    be set to a non-standard port number when necessary. If zero then the default
719 +    port number is used.
720 +
721 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
722 +    and not just the mouse.
723 +
724 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
725 +
726 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
727 +    image index and selected image index for each node to be set from a database field.
728 +
729 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
730 +    then database schema includes grants to all users. If not present then the
731 +    only user grants included are those to User PUBLIC.
732 +
733 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
734 +    and child nodes in dataset.
735 +
736 +
