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.
406 >
407 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
408 >
409 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
410 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
411 > RELEASE.
412 >
413 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
414 >
415 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
416 >
417 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
418 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
419 >   information). However, this is also a very useful mechanism for returning updated computed by
420 >   column values. Values returned as a result of executing an Insert or Update statement
421 >   replace existing values in the current row for each corresponding column.
422 >
423 >   Previously, if a dataset's select query included read only (computed by) fields then
424 >   an automatic row refresh was performed after an insert or update query had been processed,
425 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
426 >   that an automatic refresh is no longer performed if an insert or update query contains
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. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
436 >   they are called when the dataset row is being deleted, there is no value in
437 >   updating the current record from the query result. Instead, a new event handler
438 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
439 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
440 >   by the query. The event handler can then interrogate the query results and
441 >   perform whatever action is necessary. For example to confirm, to the user,
442 >   the deletion of a row with the returned values.
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 > 5. TIBTable: The GeneratorField property is now published.
449 >
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 > 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 > 8. TIBGenerator: small performance improvement by not preparing query each time
460 >   a new value is generated.
461 >
462 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
463 >
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 > 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 > 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 > 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 > 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.
600 >

602 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
603 >
604 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
605 >   changes.
606 >
607 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
608 >   Bug could result in truncated multi-byte character set values.
609 >
610 > 3. Changes consequential on moving fbintf character set utility functions from
611 >   IFirebirdAPI to IAttachment.
612 >
613 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
614 >
615 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
616 >   results in autocomplete ignoring prefix text.
617 >
618 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
619 >   entering a new name into the text box.
620 >
621 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
622 >   Firebird rather than recomputing it.
623 >
624 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
625 >   screen centre. Previously some were "poDesigned" which may be inappropriate
626 >   for multi monitor desktops.
627 >
628 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
629 >
630 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
631 >    a transaction and always reset the object.
632 >
633 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
634 >
635 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
636 >
637 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
638 >    to a gbak format archive.
639 >
640 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
641 >
642 > 16. IBLocaldb: Drop database if error creating an empty database.
643 >
644 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
645 >    unless selected node not in current dataset.
646 >
647 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
648 >    to TIBCustomService, and IBlocalDB code tidy up.
649 >
650 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
651 >    behaviour due to uninitialised variable.
652 >
653 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
654 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
655 >
656 > 21. IBSQL: When Database changed ensure that all resources are freed.
657 >
658 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
659 >
660 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
661 >    * Line Wrap on SQL Token boundaries (on user command)
662 >    * auto-complete table names in drop down list of table names
663 >    * Double click on tablename or field name adds to SQL text
664 >
665 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
666 >
667 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
668 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
669 >    workaround for a problem in fpc 3.0.4 win64).
670 >
671 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
672 >
673 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
674 >
675 > IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
676 >
677 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
678 >   include remote system name.
679 >
680 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
681 >   tables when data included in output.
682 >
683 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
684 >   and timing information to be written to stdout. This may be used to locate
685 >   performance bottlenecks.
686 >
687 > 4. SQLParser: only call "OnChanging" event handler when value is different.
688 >
689 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
690 >
691 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
692 >   that BindFields is called when the query is next activated. Avoids FieldName
693 >   not found error.
694 >
695 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
696 >   purpose and allows the programmer to define any action they want for Update, Insert
697 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
698 >   filtering of updates, or use of statements such as Grant or Revoke instead of
699 >   normal DML. See User Manual for more information.
700 >
701 > IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
702 >
703 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
704 >
705 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
706 >
707 > 3. TIBExtract: data formatted as Charset set "octets" is now output using
708 >   hexadecimal notation.
709 >
710 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
711 >   using a simple XML format.
712 >
713 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
714 >   grants to these objects.
715 >
716 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
717 >   dependency problems restoring complex databases.
718 >
719 > 7. TIBXScript: This component has been restructured to allow for the processing of
720 >   embedded XML in INSERT statements and to support interactive sources in addition
721 >   to non-interactive data sources such as files.
722 >
723 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
724 >
725 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
726 >   SET SQL DIALECT
727 >   SET TERM
728 >   SET AUTODDL
729 >   SET BAIL
730 >   SET ECHO
731 >   SET COUNT
732 >   SET STATS
733 >   SET NAMES <character set>
734 >
735 > 10. IBVersion unit added to hold current IBX Version Number information.
736 >
737 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
738 >    and domain definitions.
739 >
740 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
741 >    fully supported.
742 >
743 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
744 >
745 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
746 >

748 >
749 > See also doc/IBX4LazarusGuide.pdf for important information on
750 > upgrading to IBX2.
751 >
752 > 1. Size property of TIBStringField is now the width in characters of the field
753 >   and not the byte length. This applies only to multi-byte character sets such
754 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
755 >   code is not recognised as a bug and hence this change to align the behaviour.
756 >   The TStringField change is expected in fpc 3.2.0.
757 >
758 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
759 >   true (default) then Size property value saved in the lfm is ignored. Size is
760 >   always set from the dynamic information read from the database. It is unclear
761 >   why anyone would want to override this and set Size to false.
762 >
763 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
764 >   block.
765 >
766 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
767 >   exist when an attempt is made to connect to it (run time only) then an attempt
768 >   is made to create the database.
769 >
770 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
771 >   has been successfully created as a result of a call to CreateDatabase or when
772 >   creating a database after it was found not to exist.
773 >
774 > 6.  DBControlGrid: a race condition could result in the wrong row image being
775 >    written to the cache. This has been avoided by a trip round the message
776 >    loop before rendering the row image.
777 >
778 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
779 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
780 >    known to risk corrupt rendering of row images when the control is first
781 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
782 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
783 >
784 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
785 >    a TDateEdit control located on an editor panel.
786 >
787 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
788 >
789 > 10. DBControlGrid: Removed memory leak when updating rows.
790 >
791 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

793 > IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
794 >
795 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
796 >   when target codepage is CP_NONE. This is a workaround for
797 >   http://bugs.freepascal.org/view.php?id=30622.
798 >
799 > 2. DBLog option removed from TIBStatisticalService - not supported by server
800 >   since Firebird 1.5.
801 >
802 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
803 >   similar.
804 >
805 > 4. IBCodePage: updated mapping between codepages and character id.
806 >
807 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
808 >   Firebird. Character sets with a char width of two are not UTF16.
809 >
810 > 6. Strings received from the database are now always transliterated into UTF8
811 >   regardless of the database character set or connection character set. This
812 >   is for compatibility with the LCL.

814 > IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
815 >
816 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
817 >   read in an entire blob just to get the size of the blob. General performance
818 >   improvement when opening datasets containing blobs.
819 >
820 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
821 >
822 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
823 >   is now used.
824 >
825 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
826 >   determined.
827 >
828 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
829 >
830 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
831 >   lazarus 1.6.0
832 >
833 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
834 >   compilation error.

837 >
838 > 1. No character set specified for connection: when a text blob is retrieved, the
839 >  character set is determined by looking up the native character set using then
840 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
841 >  set as the connection.
842 >
843 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
844 >   for Login Dialog returing a change to the database path.
845 >
846 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
847 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
848 >   entered value to be saved on a project specific basis (design time only).

899 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
900 >   path is given and database attach fails due to access permission issues on the

902 >   prefixing the databasename. This should avoid problems when the database has to
903 >   be accessed by a local (e.g. classic) server and libfbembed is used.
904 >
905 > 2. Windows: revised search order for Firebird DLL:
906 >     i.   The Firebird Embedded Server in the application Directory.
907 >     ii.  If the FIREBIRD environment variable is set then the directory this
908 >          points to is searched for the FB Client DLL and then then underlying

910 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
911 >          is used to locate the Firebird installation directory and the underlying
912 >          "bin" directory is searched for the FB Client DLL.
913 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
914 >          are searched for the FB Client DLL.

934 >
935 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
936 >
937 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
938 >
939 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
940 >
941 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
942 >   i.e. when it is a calculated field
943 >
944 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
945 >   This problem was due to a race condition between recalculating row heights and
946 >   determining which row was selected by the mouse click. The row height calculation
947 >   is now deferred by an extra trip round the message loop allowing the row to
948 >   be always calculated on the current grid layout rather than risking it being
949 >   calculated on the grid layout after the expanded row has been shrunk.
950 >
951 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
952 >   Windows.
953 >
954 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
955 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
956 >   to be determined at runtime. See doc/readme.charactersets.html.
957 >
958 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
959 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
960 >
961 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
962 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
963 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
964 >
965 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
966 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
967 >   implies no truncation.
968 >
969 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
970 >
971 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
972 >   (avoids "Not in Edit Mode" error).
973 >
974 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
975 >
976 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
977 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
978 >
979 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.

981 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
982 >
983 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.

989 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
990 >
991 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
992 >     problem with row size when exception is called.
993 >
994 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
995 >
996 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
997 >     in a TCustomComboBox and ignores return key if in a TCustomMemo

999 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1000 >     keyed in i.e. when autocomplete not performed
1001 >
1002 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1003 >     console mode applications with all LCL required functions (builtin dialogs and
1004 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1005 >     not included in your project, IBX should compile and link with a console mode program.
1006 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1007 >     console mode application or the IDE will automatically assume that your
1008 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1009 >
1010 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1011 >     to use the built in dialogs and cursor management. IBDialogs is
1012 >     included by default if "ibexpress" is in your project source's "uses" clause.
1013 >     This should be the case for all projects created through the IDE. This is why
1014 >     you do not want to add the ibexpress package to console mode applications. The
1015 >     ibexpressconsolemode package has been created to allow console mode programs
1016 >     to avoid adding LCL dependencies when using IBX, while still having the
1017 >     unit search paths set up correctly.
1018 >
1019 >     Existing users should check to ensure that the "ibexpress" unit is included in
1020 >     each project's source file (*.lpr).
1021 >
1022 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
1023 >     exists, you have to first open the package in the IDE and then close it. This
1024 >     adds it to the most recently accessed packages list. To make it permanently
1025 >     available, add the package name to lazarus' staticpackages.inc file.
1026 >
1027 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
1028 >
1029 > 7.   SQL Parser can now accept quoted strings that include new lines
1030 >
1031 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1032 >     of text on start of edit. This is particularly useful when tabbing to a
1033 >     column and then inserting text.
1034 >
1035 > 9.   New Examples provided for IB Services and ISQLMonitor.
1036 >
1037 > 10. Fix error when writing to blob streams that recorded only the last buffer
1038 >    write in the blob stream. In most cases, this did not cause a problem as the
1039 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
1040 >    of a graphic type prefix was lost which caused a problem when the image could
1041 >        not be automatically recognised.
1042 >
1043 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1044 >    already open" errors due to random numbers used for the cursor name being identical.
1045 >
1046 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
1047 >    when opening the table and the Primary Key is the last or only column in the
1048 >    table. Thanks to Rick Hoover for the fix.
1049 >
1050 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1051 >    of "UTF-8", and update list of available database character sets. Existing
1052 >    users should check the current lc_ctype setting in their applications.
