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 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 >   text matches complete entry.
20 >
21 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 >   dataset are active (avoids risk of access violation if master is inactive)
23 >
24 > 6. TIBEvents: Registered property can now be set at design time even if database not open
25 >
26 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 >   This should prevent "spillover" of events between sessions.
28 >
29 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 >   This should ensure that the internal buffer is set up correctly and avoids
31 >   a duplicate initial row.
32 >
33 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 >   That is, the DataSize should be the field size * character set width. The
35 >   value returned by DataSize is now the same as the Dataset buffer size reserved
36 >   for the field.
37 >
38 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 >
40 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 >    and vice-versa. This may result in an exception being raised (correctly) for
42 >    older programs when using dataset fields added to a form and the database has been
43 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 >    In such cases, the field needs to be deleted in the IDE fields editor and then
45 >    added back in.
46 >
47 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
48 >    false if query contains white space and not just empty.
49 >
50 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
51 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
52 >    is cancelled.
53 >
54 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
55 >
56 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
57 >    not SQL Identifiers are now supported.
58 >
59 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
60 >    passed to the Firebird engine for execution.
61 >
62 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
63 >    is made to scroll back.
64 >
65 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
66 >
67 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
68 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
69 >
70 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
71 >   validated. If no match is found in the list of field names and the database has
72 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
73 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
74 >
75 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
76 >   with fpc 3.2.
77 >
78 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
79 >
80 >
81 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
82 >   and is used to override the default settings in the client side "firebird.conf" This
83 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
84 >   Each line of the string list should be a setting in the same format as "firebird.conf".
85 >   For example "WireCompression = true" in order to request wire compression on the client side.
86 >
87 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
88 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
89 >   also require a compatible setting in the server side "firebird.conf". For example
90 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
91 >   compression to be used.
92 >
93 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
94 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
95 >   ibx/examples/dbinfo for examples of how to display this information.
96 >
97 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
98 >   is a "convenience" property. If set the "WireCompression=true" is added to the
99 >   ConfigOverrides. If unchecked then this setting is removed.
100 >
101 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
102 >   not "INT64".
103 >
104 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
105 >   These are:
106 >    property TimestampFormat: string;
107 >    property DateFormat: string;
108 >    property TimeFormat: string;
109 >
110 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
111 >   DATETIME and TIME. The format strings use the standard FPC date/time format
112 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
113 >
114 >   If any of the above properties are set to an empty string, then the locale default
115 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
116 >   locale default is extended by appending '.zzz' to include milliseconds.
117 >
118 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
119 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
120 >
121 > 5. New published property for TIBCSVDataOut:
122 >     property QuoteStrings: boolean (default true)
123 >
124 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
125 >   used to delimit each and every string in the output.
126 >
127 > 6. New published properties for TIBCSVDataOut:
128 >    property FieldSeparator: string;
129 >    property HeaderSeparator: string;
130 >
131 >   Respectively, these provide the separator character(s) used to separate fields
132 >   in data and header rows. Both default to ','.
133 >
134 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
135 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
136 >    property OnFormatTextString;
137 >
138 >   This event handler can be used to process text strings before they are included
139 >   in the output e.g. to replace unprintable characters with alternative strings.
140 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
141 >
142 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
143 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
144 >   and without raising and exception if it does not.
145 >
146 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
147 >   consistency with SQL queries.
148 >
149 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
150 >    When true, SQL statement parameter names are parsed case sensitive. Note for
151 >    TIBDataSet only applies to Select query.
152 >
153 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
154 >    an IDE exception.
155 >
156 > 12. LocalDBSupport: initial database creation should now work correctly
157 >    when the schema source is an sql file.
158 >
159 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
160 >    when defined, this handler will be called by the internal TIBXScript during
161 >    initial database creation when the schema source is an sql file and may be used
162 >    to provide a visual indication of progress in console mode.
163 >
164 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
165 >    to true while a new local database is being created and its schema populated.
166 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
167 >    when the database is disconnected/connected during the create DB procedure.
168 >
169 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
170 >    are now always ignored and replaced by the user name and password provided as
171 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
172 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
173 >    completely ignored if this property is true.
174 >
175 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
176 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
177 >    ImageIndex and SelectImageIndex values on AddNode.
178 >
179 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
180 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
181 >    the same database connection.
182 >
183 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
184 >    if provided, this should be an conditional SQL expression suitable for
185 >    including in an SQL Select statement "where" clause. If non-empty and the
186 >    "Filtered" property is true then the SQL expression provided as the value of
187 >    the "Filter" property is "ANDed" with any existing condition statement
188 >    in the SQL statement's "Where" clause.
189 >
190 >    If the "Filter" property is set at run time, the "Filtered" property is true
191 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
192 >
193 >    The "Filter" condition may include IBX style parameters. In which case, their
194 >    value must be set by the dataset's "OnBeforeOpen" event handler.
195 >
196 >    This is a public property for TIBDataSet and TIBQuery query and intended for
197 >    use at run time.
198 >
199 >    Note: The property is a published property of TIBTable. The TIBTable functionality
200 >    is unaffected by this change.
201 >
202 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
203 >
204 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
205 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
206 >   mode apps.
207 >
208 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
209 >   statement. This avoids problems if "Execute Block" is used as the Query.
210 >
211 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
212 >   internal SQL tokeniser routines.
213 >
214 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
215 >   as a select statement, with or without CTEs.
216 >
217 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
218 >
219 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
220 >   internal SQL tokeniser routines.
221 >
222 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
223 >    being raised for valid set statements processed by a data formatter.
224 >
225 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
226 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
227 >   the path of the Firebird Library used by the database/services connection.
228 >
229 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
230 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
231 >   services connection.
232 >
233 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
234 >   or param name is not a valid SQL identifier.
235 >
236 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
237 >    view of whether the text box should be editable when no DataSource is specified.
238 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
239 >    ReadOnly is false, the text box is editable when no DataSource is specified.
240 >
241 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
242 >    the FBLIB environment variable. If you do not want to permit this then you
243 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
244 >    this setting.
245 >
246 > IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
247 >
248 > 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
249 >   Utf8EscapeControlChars
250 >
251 > IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
252 >
253 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
254 > all previous copies of the IBX source code tree before installing this release.
255 >
256 > The IBX packages used by most users have not changed, with one exception. The
257 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
258 > to use the IBServices unit in your applications, please add the iblegacyServices
259 > to the list of dependencies. To do this, open the Project Inspector and select
260 > Add->New Requirement and select "ibLegacyServices" from the list of available
261 > packages.
262 >
263 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
264 >   the IBServices unit providing what is intended to be a clearer and easier to
265 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
266 >   more information and the guide to "Firebird Service Management Using IBX".
267 >   As indicated above, the legacy services components are still available and
268 >   provided in a separate package. There is no need to update working applications
269 >   using the older versions except for an additional package dependency.
270 >
271 > 2. The IBX packages and source code tree have been re-organised in an attempt to
272 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
273 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
274 >   new set of IBX packages.
275 >
276 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
277 >   updated to use the new Services API components.
278 >
279 > 4. The iblocal package has been updated to use the new Services API components.
280 >
281 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
282 >   TIBXSecurityService. It had been wrongly classified in the previous version
283 >   as a per database configuration item. It is global to a server and hence
284 >   correctly positioned as part of the Security Package. In the DBAdmin example,
285 >   the setting has moved to the mappings page.
286 >
287 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
288 >   are ignored.
289 >
290 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
291 >   closed before the database is dropped. Before and After Disconnect event handlers
292 >   are also fired.
293 >
294 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
295 >   is started and not just the first time.
296 >
297 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
298 >   depenendency with comp type.
299 >
300 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
301 >
302 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
303 >    then this is recognised and not ignored.
304 >
305 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
306 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
307 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
308 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
309 >
310 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
311 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
312 >    counters for the select query. Note: stats accumulate after each fetch from
313 >    the database. To get total query cost after open, call the "Last" method
314 >    and then GetPerfStatistics.
315 >
316 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
317 >
318 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
319 >    in parenthesises.
320 >
321 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
322 >    SQL identifiers are always delimited by double quotes. If false, then they are
323 >    only delimited if the identifier is a reserved word, contains lower case or special
324 >    characters. Set this property to true to retain previous behaviour.
325 >
326 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
327 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
328 >
329 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
330 >       property MasterDetailDelay: integer {defaults to zero}
331 >
332 >    When non-zero and the dataset is a detail table referencing a master table
333 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
334 >    then a synchronisation delay is added (in milliseconds) between the master
335 >    row changing and the detail dataset being re-opened. If the master dataset
336 >    is scrolled before the delay expires then the delay is reset. This can be used
337 >    to avoid performance overheads when scrolling through a large master dataset.
338 >
339 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
340 >    chreads unit must be included in your project. TTimer is not used in order
341 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
342 >
343 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
344 >    with Extract Option eoDatabase.
345 >
346 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
347 >    When a deLayoutChanged event is reported on the ListSource dataset, the
348 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
349 >    relationship with the control's datasource (master).
350 >
351 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
352 >
353 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
354 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
355 >
356 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
357 >    DDL (Firebird 3 and later only).
358 >
359 > 22. TIBLookupComboBox Autocomplete Fixes:
360 >    i. Only appended text is now selected after autocomplete.
361 >    ii. Uppercase keys no longer ignored for autocomplete.
362 >    iii. Retain Prefix case is now honoured correctly.
363 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
364 >        before autocomplete performed. i.e. behaviour now the same as when
365 >        no DataSource assigned.
366 >
367 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
368 >    between SQL statements.
369 >
370 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
371 >    ObjectNames are converted to upper case before matching against metadata object
372 >    names, unless the objectname is delimited by double quotes, in which case, the
373 >    double quotes are removed and the remaining string is used (unmodified) to match
374 >    against the metadata object name.
375 >
376 >    If true then the ObjectName is used as is without modification and matched
377 >    against the metadata object name. No attempt is made to remove double quotes.
378 >
379 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
380 >    with eoTrigger, these extract types can be used to select only Database Triggers,
381 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
382 >
383 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
384 >    statement separate character is now reset to the default (';').
385 >
386 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
387 >
388 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
389 >    a commit or reconnect statement and instead activated only when next SQL statement
390 >    is executed.
391 >
392 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
393 >
394 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
395 >    converting statement to upper case.
396 >
397 > 31. TIBExtract: metadata comments now supported. New published property
398 >    IncludeMetaDataComments (default true). If true then metadata comments included
399 >    in extracted DDL. New Extract Object member eoComments. This may be used with
400 >    ExtractObject method to list all metadata comments.
401 >
402 > 32. TIBExtract: ListObjectNames method added.
403 >
404 > 33. Updated Database component editor to support additional connection string
405 >    types.

427     a returning clause that updates one or more fields on the current row. A full row
428     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
429     field values and the select query contains read only fields. Use of Insert/update

430 >   returning should be significantly more efficient than executing a refresh query.
431  
432     This behaviour change is intended to be backwards compatible and there should be no need to change
433     existing programs, other than to improve performance by using the new capability.
434  
435 < 3. TIBTable: generated Insert and Update SQL now include a RETURNING clause for

443 >
444 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
445     any Computed By or Identity Columns. The IBTables example has been updated to
446     illustrate the computation of the employee Full Name on update.
447  
448 < 4. TIBTable: The GeneratorField property is now published.
448 > 5. TIBTable: The GeneratorField property is now published.
449  
450 < 5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
450 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
451     When InsertSQL is generated, the Identity columns are not included in the list of values to
452     be inserted. A RETURNING clause is added to the insert statement to return the value of
453     each Identity column after the insert is executed.
454  
455 < 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
455 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
456     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
457     Insert..Returning clause.
458  
459 < 7. TIBGenerator: small performance improvement by not preparing query each time
459 > 8. TIBGenerator: small performance improvement by not preparing query each time
460     a new value is generated.
461  
462 < 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
462 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
463  
464 < 9. Property editors will now sync table name to a System Table when "Include System
465 <   Tables" is selected and the query is for a System Table.
464 > 10. Property editors will now sync table name to a System Table when "Include System
465 >    Tables" is selected and the query is for a System Table.
466  
467 < 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
467 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
468      values are no longer converted to milliseconds from TDateTime and then back again
469      to TDateTime (the conversion to milliseconds is the default TDataset approach).
470  
471 < 11. Property Editors handling of Stored Procedures.
471 > 12. Property Editors handling of Stored Procedures.
472      * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
473        which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
474        query).
475      * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
476  
477 < 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
477 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
478      can be used to select a package. If non-empty, the stored procedure name is
479      expected to be a stored procedure defined in the specified package and the
480      generated SQL will be as required for a stored procedure located in a package.
481  
482 < 13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
482 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
483      a "Package Name" drop down box to allow selection of a Firebird 3 Package from
484      which a stored procedure can be selected. With no package name selected, non-package
485      stored procedures are listed.
486  
487 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
488 +    for password on reconnect.
489 +
490 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
491 +    and character set name.
492 +
493 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
494 +    DB info lookups"
495 +
496 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
497 +
498 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
499 +
500 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
501 +    parameters. This stops an exception being raised when the field cannot be
502 +    located in the record buffer.
503 +
504 + 21. Property Editors now automatically include System Tables when opened and when the query table
505 +    is a System Table.
506 +
507 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
508 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
509 +
510 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
511 +    add the SPB item isc_spb_expected_db. This names a database using
512 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
513 +    database. examples/services re-written to illustrate use of "expected_db".
514 +
515 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
516 +    This avoids truncated backups when the server returns a timeout (busy) response.
517 +
518 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
519 +
520 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
521 +    databasenames. These are respectively expanded to the local system's temp directory
522 +    (including trailing delimiter) or to a prescribed data directory (including
523 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
524 +    in the user's home directory. The hidden directory name is either the string returned
525 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
526 +    Under Windows, the directory is the same as the Data Directory as decribed
527 +    above but instead prefixed by the User's application data path. These may be
528 +    used to improve application portability for Personal Databases.
529 +
530 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
531 +    this has not worked for a long time and is not useful either. FieldDefs should be
532 +    managed using the Fields Editor as with any other dataset. To access the fields
533 +    editor for a TIBTable component, double click on the component. The fields editor
534 +    is then displayed.
535 +
536 + 28. TIBDatabaseInfo: new properties/function
537 +     * DateDBCreated (returns date/time database created)
538 +     * TransactionCount (returns no. of active transactions)
539 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
540 +     * PagesFree (Firebird 3 or later)
541 +     * PagesUsed (Firebird 3 or later)
542 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
543 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
544 +
545 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
546 +
547 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
548 +
549 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
550 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
551 +
552 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
553 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
554 +    firing during backup and restore.
555 +
556 + 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
557 +    for verbose output using the new property "StatisticsRequested".
558 +    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
559 +
560 + 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
561 +
562 + 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
563 +    palette. This uses the online validation feature added in Firebird 2.5. The
564 +    services's properties enable inclusion/exclusion of tables and indexes using
565 +    regular expressions. See.
566 +    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
567 +
568 + 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
569 +    option on a database.
570 +
571 + 37. TIBCustomService: Assign method implemented to allow copying of service login
572 +    context between service API components. "Detach" method now only detaches
573 +    service when last reference to the service interface detaches. Tidy up of
574 +    code for SetActive and Attach methods including password hiding.
575 +
576 + 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
577 +    and used to determine the auth method and protocol used for the connection.
578 +
579 + 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
580 +    a Create Database Statement generated by IBX.
581 +
582 + 40. All IBServices now have an additional published property "PortNo". This may
583 +    be set to a non-standard port number when necessary. If zero then the default
584 +    port number is used.
585 +
586 + 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
587 +    and not just the mouse.
588 +
589 + 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
590 +
591 + 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
592 +    image index and selected image index for each node to be set from a database field.
593 +
594 + 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
595 +    then database schema includes grants to all users. If not present then the
596 +    only user grants included are those to User PUBLIC.
597 +
598 + 45. TIBTreeView: performance improvement. When expanding include both expanded node
599 +    and child nodes in dataset.
