IBX Change Log  version (2.6-4 Build 14172) Thu, 04 Jan 2024 11:55:41 +0000

1. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
   if ApplyUpdates called before a cursor exists.

2. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
   creating the blob.

3. TIBCustomDataset.Requery: The display buffer pool is now also reset avoiding
   issues with left over pointers to invalid internal buffers.

4. TIBCustomDataset.PrimaryKeys when used in InternalRefresh. when more than one
   primary key is used by the dataset then the list of primary keys is now
   properly separated by a ';'.

5. When refresh is called for a dataset without any primary keys (e.g. views and
   stored procedures), the internal record number is now used to restore the cursor
   following the refresh. However, it should be noted that cannot be 100% reliable.
   The internal record number simply reflects the record fetch order and this can
   change between successive queries if records are inserted or deleted by the
   current or another user (if the read_committed transaction isolation level is used).

6. Inserting a record at the start of a grid and then resizing the grid should
   no longer result in an apparent duplication of records in the grid. Note: this
   was due to TDataset.SetCurrentRecord ignoring the bookmark flag (bfInserted). IBX
   works around this by no longer using this bookmark flag value.

7. Inserting a record into an empty grid and then resizing the grid should
   no longer result in an apparent duplication of records in the grid.

IBX Change Log  version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100

1. Update to calls to EInterbaseError to add default code page. Consequential
   on change to fbintf.

2. Update some examples to replace test for null date with the NullDate constant
   instead of zero. This is because Laz 3.0 changes the value of NullDate.

IBX Change Log  version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100

1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
   with later versions of fpc - later than 3.2.2.

2. IBUpdateSQL. update internal queries if parent dataset database changed.

3. IBUpdateSQL: Do not prepare an empty internal query.

4. IBBufferedCursors: avoid range error when max field no. is > fields.count

5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count

IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100

1. Maintenance update of 2.6.0. This version is still at beta.

2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623

3. ibxscript: When parsing a store procedure or function with a variable name
   enclosed in doublequotes, the double quotes are no longer removed.

IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100

NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY 
      ISSUES TO support@mwasoftware.co.uk

1. Complete rewrite of internal buffer management in order to improve performance
   and maintainability. Highlights:

   * Extending the size of the buffer pool no longer has to copy the entire record
     cache. Instead, a new extent is simply added to the buffer pool.
   * A memory to memory copy of each display buffer now is avoided when scolling the
     dataset.
   * A separate set of buffers is now used for calculated fields. This avoids
     having to keep copies of calculated field values in the buffer cache.
   * Compact bitmaps are used to record null status and need to refresh in each
     buffer.
   * Display buffer type changed from PChar to TRecordBuffer in line with change of
     buffer type in FCL-DB.

2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.

3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
   If either or both of these flags are set at design time (using the fields editor)
   then this forces a row refresh on respectively insert or update, or both, when the
   corresponding field is not present in an SQL RETURNING clause.

4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
   maintainability and readability and to add identification of primary key fields.

5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
   as a refresh of the current row. However, this is different behaviour to that described
   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
   the dataset from the underlying database, and attempts to reposition the cursor on
   the same record as it was". IBX now complies with the FPC definition of Refresh.

6. A progammatic Row Refresh should no longer be required.
   Use Insert/Update... returning to refresh any fields that may change following an
   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
   for the field at Design Time to force a row refresh if not in the returning clause.

7. It should now be possible to insert a row into an empty unidirectional dataset.

8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
   This gives the number of buffers in the initial block for the buffer pool in
   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
   for small datasets.

IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000

1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.

2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0

3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0

IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100

1. TIBTransaction: new properties
    property TransactionID: integer read GetTransactionID;
    property IsReadOnly: boolean read GetIsReadOnly;
    {published}
    property TransactionName: string read FTransactionName write SetTransactionName;

2. IBCustomDataset: per row blob and array buffer cached clear before processing
   Insert or Update...Returning. This allows blobs and arrays to be returned
   by the statement.

3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.

4. TransactionName initialised to a newly generated GUID if empty.

5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
   for the fbintf package's journaling capability. TIBJournal is used to set the
   file path and filename for the journal file and to Enabled (start journaling) and
   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
   more information, and comments in IBJournal.pas.

6. TIBDatabase.InternalTransaction is now a read only transaction.

7. Bug fix: blob id no longer set to null on update when blob has not been
   retrieved.

8. Row auto refreshed on update/insert if blob or array field updated and field
   not in a returning clause.

9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
   buffer overhead and avoids problem when refresh query has a different column
   count to select query i.e. incorrectly changing number of columns.

10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.

11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
    string. Note that the Version property returns an InterBase compatible version string.

12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.

IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000

1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
   This is for compatibility with Firebird 5 where Update...Returning can return
   a cursor.

IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100

1. Add try-..except check when initially loading library in IDE. This should
ensure that IDE continues to load even when a failure occurs in IBX load
library.

2. IBXScript: now recognises a CASE...END block within a stored procedure and
   hence will correctly detect end of the outer containing block when the block
   contains a SELECT ... CASE ... END construct.

3. IBExtract: some further tidying up to remove extraneous white space.

4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
   errors when extra elements are added to DB.TFieldType.

5. IBUpdate: updated to reflect changes to ISQLParam.

6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.

7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.

8. IBSQL: Support for scrollable cursors added (note: local databases only)

IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100

1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
   exception of those defined to be one byte wide e.g. DBImplementationNo.

2. TIBSQL: Batch Update/Insert support added.

3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
   is no longer automatically converted to upper case when it is syntactically a
   SQL Identifier. This is to support the use of stored procedures defined e.g.
   as CREATE PROCEDURE "iCASE".

   There could be a backwards compatibility issue when the StoredProcName was entered
   manually at design time. That is not selected from the drop down list. If the
   StoredProcName is entered in mixed case and the procedure was declared e.g. as
   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
   ensure that the value of the StoredProcName is all upper case, unless it was
   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
   quotes).

   Note that when a stored procedure name was declared delimited in double quotes,
   as in the first example above, the value of the StoredProcName property must not
   include the delimiters (double quotes).

4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
   upgrade.conf was not found. This replaces silently ignoring the problem.

5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
   'Version.%.3d' and is used to generate the section header names (for a given
   version no.) in the upgrade.conf file.

IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100

1. -c command line option added to fbsql example program. Used to set connection
   character set.

IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000

1. Firebird 4 support added.

2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
   extended precision NUMERIC fields are supported.

3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.

4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.

5. IBExtract now supports FB4 enhancements:
   - new data types as above
   - Identity column extensions
   - Default user role
   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
   - Internal Functions

6. IBExtract: new event: OnExtractLines.

7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145

8. IBXServices: Server version no. parsing now allows any letter before major version number
   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"

9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
   format for rendering a time zone.

10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
     to convert TIME WITH TIME ZONE data type values to and from GMT.

11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
    IIBGUIInterface and IIBTimerInf respectively.

12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
    now accessible as properties of TIBDatabase and TIBTransaction respectively.

13. String Fields: when a fixed character with (CHAR) field is returned, it is now
    truncated to its fixed character width rather than being right padded with
    white space to the maximum data size.

14. TIBTable.Empty table. In additional to deleting all records in the underlying
    table, the internal buffers are now also flushed ensuring that the TIBTable is
    also empty.

15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.

16. TIBXControlService descendents: DatabaseName may now be set using a database
    connect string. The database name is extracted from the connect string.

17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel

18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.

19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
    not being present as required.

20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
    version that can be customised to work with other database drivers.

21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
    unnecessary CR at end of line on Unix platforms.

22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
    seconds in order to reduce risk of message loss.

23. ISQLMonitor: read and write count statistics now available via:
      property TIBSQLMonitor.ReadCount;
      IIBSQLMonitorHook.GetWriteCount: integer;

24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.

IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100

1.  TIBStringField: when a string value is read from a dataset buffer, if the
    number of UTF8 characters exceeds the string size then string is truncated
    to the maximum string size. This is  usually a problem with fixed width columns
    right padded with white space.

2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
    If SQLFiltered is set then when a dataset is opened, each line in the
    SQLFilterParams property is assumed to be a SQL condition clause and
    ANDed into the Where clause of the SQL Select statement provided as a
    dataset property. Each such SQL condition thus acts as an additional filter
    on the dataset.

3.  The Filtered property inherited from TDataset is no longer used for SQL (server
    side filters).

4. IBLookupComboEditBox: Selection should no longer reset to start of text when
   text matches complete entry.

5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
   dataset are active (avoids risk of access violation if master is inactive)

6. TIBEvents: Registered property can now be set at design time even if database not open

7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
   This should prevent "spillover" of events between sessions.

8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
   This should ensure that the internal buffer is set up correctly and avoids
   a duplicate initial row.

9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
   That is, the DataSize should be the field size * character set width. The
   value returned by DataSize is now the same as the Dataset buffer size reserved
   for the field.

10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.

11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
    and vice-versa. This may result in an exception being raised (correctly) for
    older programs when using dataset fields added to a form and the database has been
    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
    In such cases, the field needs to be deleted in the IDE fields editor and then
    added back in.

12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
    false if query contains only white space and not just empty.

12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
    is cancelled.

13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
    called on a null field.

14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
    results in an empty dataTC86                Client side Filtered Dataset    1       X
set.

15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
    a cached update is applied and an exception is raised.

16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.

17. Console Mode Local Database support: backup/restore should now work correctly.

18. Local Database Support: if an upgrade fails, a downgrade is now performed if
    possible and an exception raised.

19. MinimumVersionNo added to Local Database Support. Database will not open if
    below this version no. and upgrade not possible.

IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100

1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
    not SQL Identifiers are now supported.

2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
    passed to the Firebird engine for execution.

3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
    is made to scroll back.

4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf

5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
   only enclosed in double quotes in SQL dialect 3 and when it needs to be.

6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
   validated. If no match is found in the list of field names and the database has
   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.

7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
   with fpc 3.2.

IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000


1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
   and is used to override the default settings in the client side "firebird.conf" This
   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
   Each line of the string list should be a setting in the same format as "firebird.conf".
   For example "WireCompression = true" in order to request wire compression on the client side.

   Note: explicit settings in the client side "firebird.conf" appear to take precedence
   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
   also require a compatible setting in the server side "firebird.conf". For example
   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
   compression to be used.

   Whether or not WireCompression or WireCrypt are in use can be checked using the information
   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
   ibx/examples/dbinfo for examples of how to display this information.

2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
   is a "convenience" property. If set the "WireCompression=true" is added to the
   ConfigOverrides. If unchecked then this setting is removed.

3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
   not "INT64".

4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
   These are:
    property TimestampFormat: string;
    property DateFormat: string;
    property TimeFormat: string;

   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
   DATETIME and TIME. The format strings use the standard FPC date/time format
   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).

   If any of the above properties are set to an empty string, then the locale default
   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
   locale default is extended by appending '.zzz' to include milliseconds.

   TIBCSVDataOut by default sets these properties to the empty string, while the other
   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.

5. New published property for TIBCSVDataOut:
     property QuoteStrings: boolean (default true)

   If false then strings are unquoted, otherwise, the QuoteChar property value is
   used to delimit each and every string in the output.

6. New published properties for TIBCSVDataOut:
    property FieldSeparator: string;
    property HeaderSeparator: string;

   Respectively, these provide the separator character(s) used to separate fields
   in data and header rows. Both default to ','.

7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
    property OnFormatTextString;

   This event handler can be used to process text strings before they are included
   in the output e.g. to replace unprintable characters with alternative strings.
   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.

8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
   Uses "FindParam" if in order to find out if a parameter with a given name exists
   and without raising and exception if it does not.

9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
   consistency with SQL queries.

10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
    When true, SQL statement parameter names are parsed case sensitive. Note for
    TIBDataSet only applies to Select query.

11. IBEvents: removing a TIBEvent component from a form should no longer result in
    an IDE exception.

12. LocalDBSupport: initial database creation should now work correctly
    when the schema source is an sql file.

13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
    when defined, this handler will be called by the internal TIBXScript during
    initial database creation when the schema source is an sql file and may be used
    to provide a visual indication of progress in console mode.

14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
    to true while a new local database is being created and its schema populated.
    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
    when the database is disconnected/connected during the create DB procedure.

15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
    are now always ignored and replaced by the user name and password provided as
    the login parameters for the TIBDatabase referenced from the TIBXScript. The
    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
    completely ignored if this property is true.

16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
    ImageIndex and SelectImageIndex values on AddNode.

17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
    the same database connection.

18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
    if provided, this should be an conditional SQL expression suitable for
    including in an SQL Select statement "where" clause. If non-empty and the
    "Filtered" property is true then the SQL expression provided as the value of
    the "Filter" property is "ANDed" with any existing condition statement
    in the SQL statement's "Where" clause.

    If the "Filter" property is set at run time, the "Filtered" property is true
    and the dataset is already open, then the dataset is closed and re-opened automatically.

    The "Filter" condition may include IBX style parameters. In which case, their
    value must be set by the dataset's "OnBeforeOpen" event handler.

    This is a public property for TIBDataSet and TIBQuery query and intended for
    use at run time.

    Note: The property is a published property of TIBTable. The TIBTable functionality
    is unaffected by this change.

IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000

1. Remove need to check for IsMultiThread by providing access to GUI timers via
   IBGUIInterface. Note: master/detail delay timer does not apply to console
   mode apps.

2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
   statement. This avoids problems if "Execute Block" is used as the Query.

3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
   internal SQL tokeniser routines.

4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
   as a select statement, with or without CTEs.

5. IBSQLParser: parser now recognises the "ROWS" clause.

6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
   internal SQL tokeniser routines.

7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
    being raised for valid set statements processed by a data formatter.

8. New published property for TIBDatabase and TIBXServicesConnection. This is
   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
   the path of the Firebird Library used by the database/services connection.

9. New read only public property for TIBDatabase and TIBXServicesConnection. This
   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
   services connection.

10.SQL Property editors now quote parameter names if "Quote identifier" is selected
   or param name is not a valid SQL identifier.

11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
    view of whether the text box should be editable when no DataSource is specified.
    TIBLookupComboEditBox has been updated to workaround this problem. As long as
    ReadOnly is false, the text box is editable when no DataSource is specified.

12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
    the FBLIB environment variable. If you do not want to permit this then you
    must modify the Register procedure in the design/IBDBReg.pas unit to remove
    this setting.

IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100

1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
   Utf8EscapeControlChars

IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100

IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
all previous copies of the IBX source code tree before installing this release.

The IBX packages used by most users have not changed, with one exception. The
IBServices unit has been moved to the package iblegacyServices.lpk. To continue
to use the IBServices unit in your applications, please add the iblegacyServices
to the list of dependencies. To do this, open the Project Inspector and select
Add->New Requirement and select "ibLegacyServices" from the list of available
packages.

1. New unit IBXServices. The IBXServices unit is a re-architectured update of
   the IBServices unit providing what is intended to be a clearer and easier to
   use set of IB Services components. See Chapter 10 of the IBX User Guide for
   more information and the guide to "Firebird Service Management Using IBX".
   As indicated above, the legacy services components are still available and
   provided in a separate package. There is no need to update working applications
   using the older versions except for an additional package dependency.

2. The IBX packages and source code tree have been re-organised in an attempt to
   finally get rid of the "duplicate ppu" warnings. This re-organisation should
   not affect existing users. Section 2.3 of the IBX User Guide describes the
   new set of IBX packages.

3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
   updated to use the new Services API components.

4. The iblocal package has been updated to use the new Services API components.

5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
   TIBXSecurityService. It had been wrongly classified in the previous version
   as a per database configuration item. It is global to a server and hence
   correctly positioned as part of the Security Package. In the DBAdmin example,
   the setting has moved to the mappings page.

6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
   are ignored.

7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
   closed before the database is dropped. Before and After Disconnect event handlers
   are also fired.

8. TIBTransaction: OnStartTransaction event now fires every time the transaction
   is started and not just the first time.

9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
   depenendency with comp type.

10. IBDataOutput: select query data output is now sent to stdout instead of stderr.

11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
    then this is recognised and not ignored.

12. TIBDataSet, TIBQuery, TIBTable: additions:
    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
    function GetPerfStatistics(var stats: TPerfCounters): boolean;
    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;

    GetRowsAffected returns the affected row counts from the last insert/update/delete
    if EnableStatistics = true then GetPerfStatistics returns the current stats
    counters for the select query. Note: stats accumulate after each fetch from
    the database. To get total query cost after open, call the "Last" method
    and then GetPerfStatistics.

    See ibx/examples/consolemode for an example of the use of GetPerfStatistics

13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
    in parenthesises.

14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
    SQL identifiers are always delimited by double quotes. If false, then they are
    only delimited if the identifier is a reserved word, contains lower case or special
    characters. Set this property to true to retain previous behaviour.

15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.

16. TIBDataSet, TIBQuery, TIBTable: addition:
       property MasterDetailDelay: integer {defaults to zero}

    When non-zero and the dataset is a detail table referencing a master table
    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
    then a synchronisation delay is added (in milliseconds) between the master
    row changing and the detail dataset being re-opened. If the master dataset
    is scrolled before the delay expires then the delay is reset. This can be used
    to avoid performance overheads when scrolling through a large master dataset.

    Note: uses fptimer and hence requires a thread manager. Under Linux the
    chreads unit must be included in your project. TTimer is not used in order
    to avoid an LCL dependency. Requires FPC 3.0.2 or later.

17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
    with Extract Option eoDatabase.

18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
    When a deLayoutChanged event is reported on the ListSource dataset, the
    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
    relationship with the control's datasource (master).

19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.

20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
    stubs. Pedantic fix really, as procedures output in dependency order anyway.

21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
    DDL (Firebird 3 and later only).

22. TIBLookupComboBox Autocomplete Fixes:
    i. Only appended text is now selected after autocomplete.
    ii. Uppercase keys no longer ignored for autocomplete.
    iii. Retain Prefix case is now honoured correctly.
    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
        before autocomplete performed. i.e. behaviour now the same as when
        no DataSource assigned.

23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
    between SQL statements.

24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
    ObjectNames are converted to upper case before matching against metadata object
    names, unless the objectname is delimited by double quotes, in which case, the
    double quotes are removed and the remaining string is used (unmodified) to match
    against the metadata object name.

    If true then the ObjectName is used as is without modification and matched
    against the metadata object name. No attempt is made to remove double quotes.

25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
    with eoTrigger, these extract types can be used to select only Database Triggers,
    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.

26. TIBXScript: If an exception occurs during the processing of a statement, the
    statement separate character is now reset to the default (';').

27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.

28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
    a commit or reconnect statement and instead activated only when next SQL statement
    is executed.

29. TIBSQL.HasField should no longer generate and exception when the field does not exist.

30. TIBXScript: case insensitive regex now used when matching statements instead of
    converting statement to upper case.

31. TIBExtract: metadata comments now supported. New published property
    IncludeMetaDataComments (default true). If true then metadata comments included
    in extracted DDL. New Extract Object member eoComments. This may be used with
    ExtractObject method to list all metadata comments.

32. TIBExtract: ListObjectNames method added.

33. Updated Database component editor to support additional connection string
    types.

IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000

NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
RELEASE.

NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.

1. IBExtract: Identity columns - add additional check for null column for generator name.

2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
   information). However, this is also a very useful mechanism for returning updated computed by 
   column values. Values returned as a result of executing an Insert or Update statement
   replace existing values in the current row for each corresponding column. 

   Previously, if a dataset's select query included read only (computed by) fields then
   an automatic row refresh was performed after an insert or update query had been processed,
   irrespective of the setting of the "ForcedUpdates" property. This has changed such
   that an automatic refresh is no longer performed if an insert or update query contains
   a returning clause that updates one or more fields on the current row. A full row
   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
   field values and the select query contains read only fields. Use of Insert/update
   returning should be significantly more efficient than executing a refresh query.

   This behaviour change is intended to be backwards compatible and there should be no need to change 
   existing programs, other than to improve performance by using the new capability.

3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
   they are called when the dataset row is being deleted, there is no value in
   updating the current record from the query result. Instead, a new event handler
   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
   an OnDeleteReturning event handler is provided then it is called with the IResults returned
   by the query. The event handler can then interrogate the query results and
   perform whatever action is necessary. For example to confirm, to the user,
   the deletion of a row with the returned values.

4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
   any Computed By or Identity Columns. The IBTables example has been updated to
   illustrate the computation of the employee Full Name on update.

5. TIBTable: The GeneratorField property is now published.

6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
   When InsertSQL is generated, the Identity columns are not included in the list of values to
   be inserted. A RETURNING clause is added to the insert statement to return the value of
   each Identity column after the insert is executed.

7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
   Insert..Returning clause.

8. TIBGenerator: small performance improvement by not preparing query each time
   a new value is generated.

9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.

10. Property editors will now sync table name to a System Table when "Include System
    Tables" is selected and the query is for a System Table.

11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
    values are no longer converted to milliseconds from TDateTime and then back again
    to TDateTime (the conversion to milliseconds is the default TDataset approach).

12. Property Editors handling of Stored Procedures.
    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
      query).
    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).

13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
    can be used to select a package. If non-empty, the stored procedure name is
    expected to be a stored procedure defined in the specified package and the
    generated SQL will be as required for a stored procedure located in a package.

14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
    which a stored procedure can be selected. With no package name selected, non-package
    stored procedures are listed.

15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
    for password on reconnect.

16. TIBDatabase: use IAttachment for connection default character set id, code page
    and character set name.

17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
    DB info lookups"

18. IBExtract: now supports DDL Triggers and Grants to DDL objects.

19. Add a property Editor for TIBUpdate.RefreshSQL.

20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
    parameters. This stops an exception being raised when the field cannot be
    located in the record buffer.

21. Property Editors now automatically include System Tables when opened and when the query table
    is a System Table.

22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
    This avoids errors due to a stale SQRB or SRB being used for the next query.

23. IBServices: Service attach parameters now include "expected_db". This is used to
    add the SPB item isc_spb_expected_db. This names a database using
    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
    database. examples/services re-written to illustrate use of "expected_db".

24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
    This avoids truncated backups when the server returns a timeout (busy) response.

25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.

26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
    databasenames. These are respectively expanded to the local system's temp directory
    (including trailing delimiter) or to a prescribed data directory (including
    trailing delimiter). Under Unix systems the data directory is a hidden directory
    in the user's home directory. The hidden directory name is either the string returned
    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
    Under Windows, the directory is the same as the Data Directory as decribed
    above but instead prefixed by the User's application data path. These may be
    used to improve application portability for Personal Databases.

27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
    this has not worked for a long time and is not useful either. FieldDefs should be
    managed using the Fields Editor as with any other dataset. To access the fields
    editor for a TIBTable component, double click on the component. The fields editor
    is then displayed.

28. TIBDatabaseInfo: new properties/function
     * DateDBCreated (returns date/time database created)
     * TransactionCount (returns no. of active transactions)
     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
     * PagesFree (Firebird 3 or later)
     * PagesUsed (Firebird 3 or later)
     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)

29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.

30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).

31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).

32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
    firing during backup and restore.

33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
    for verbose output using the new property "StatisticsRequested".
    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats

34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).

35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
    palette. This uses the online validation feature added in Firebird 2.5. The
    services's properties enable inclusion/exclusion of tables and indexes using
    regular expressions. See.
    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation

36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
    option on a database.

37. TIBCustomService: Assign method implemented to allow copying of service login
    context between service API components. "Detach" method now only detaches
    service when last reference to the service interface detaches. Tidy up of
    code for SetActive and Attach methods including password hiding.

38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
    and used to determine the auth method and protocol used for the connection.

39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
    a Create Database Statement generated by IBX.

40. All IBServices now have an additional published property "PortNo". This may
    be set to a non-standard port number when necessary. If zero then the default
    port number is used.

41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
    and not just the mouse.

42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.

43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
    image index and selected image index for each node to be set from a database field.

44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
    then database schema includes grants to all users. If not present then the
    only user grants included are those to User PUBLIC.

45. TIBTreeView: performance improvement. When expanding include both expanded node
    and child nodes in dataset.


IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000

1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
   changes.

2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
   Bug could result in truncated multi-byte character set values.

3. Changes consequential on moving fbintf character set utility functions from
   IFirebirdAPI to IAttachment.

4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true

5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
   results in autocomplete ignoring prefix text.

6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
   entering a new name into the text box.

7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
   Firebird rather than recomputing it.

8. Property Editor positioning tidy up: All IBX Property editors should now be
   screen centre. Previously some were "poDesigned" which may be inappropriate
   for multi monitor desktops.

10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.

11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
    a transaction and always reset the object.

12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.

13. TIBXScript: Allow for override of database filename in Create Database statements.

14. IBLocaldb: Support initialisation of the database from an SQL script in addition
    to a gbak format archive.

15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.

16. IBLocaldb: Drop database if error creating an empty database.

17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
    unless selected node not in current dataset.

18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
    to TIBCustomService, and IBlocalDB code tidy up.

19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
    behaviour due to uninitialised variable.

20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.

21. IBSQL: When Database changed ensure that all resources are freed.

22. IBCustomDataset: When database changed ensure that queries an unprepared.

23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
    * Line Wrap on SQL Token boundaries (on user command)
    * auto-complete table names in drop down list of table names
    * Double click on tablename or field name adds to SQL text

24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).

25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
    TVariantArray. Seems to avoid memory corruption in Windows (probably a
    workaround for a problem in fpc 3.0.4 win64).

26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.

27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000

1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
   include remote system name.

2. TIBExtract: No longer include comment header and COMMIT statement for empty
   tables when data included in output.

3. Profiling: IBSQL now has conditional compilation flags to enable query performance
   and timing information to be written to stdout. This may be used to locate
   performance bottlenecks.

4. SQLParser: only call "OnChanging" event handler when value is different.

5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit

6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
   that BindFields is called when the query is next activated. Avoids FieldName
   not found error.

7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
   purpose and allows the programmer to define any action they want for Update, Insert
   or Delete. This may be complex SQL (similar to a Trigger), application specific
   filtering of updates, or use of statements such as Grant or Revoke instead of
   normal DML. See User Manual for more information.

IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000

1. TIBEvents: Fix uninitialised variable that could result in lost events.

2. TIBExtract: Added support for FB3 "USAGE" privilege.

3. TIBExtract: data formatted as Charset set "octets" is now output using
   hexadecimal notation.

4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
   using a simple XML format.

5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
   grants to these objects.

6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
   dependency problems restoring complex databases.

7. TIBXScript: This component has been restructured to allow for the processing of
   embedded XML in INSERT statements and to support interactive sources in addition
   to non-interactive data sources such as files.

8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.

9. TIBXScript: ISQL compatiable Set statements are now supported:
   SET SQL DIALECT
   SET TERM
   SET AUTODDL
   SET BAIL
   SET ECHO
   SET COUNT
   SET STATS
   SET NAMES <character set>

10. IBVersion unit added to hold current IBX Version Number information.

11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
    and domain definitions.

12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
    fully supported.

13. TIBExtract: when a database dump includes data, the generator values are now also set.

14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000

See also doc/IBX4LazarusGuide.pdf for important information on
upgrading to IBX2.

1. Size property of TIBStringField is now the width in characters of the field
   and not the byte length. This applies only to multi-byte character sets such
   as UTF8. The original approach aligned with TStringField. However, the TStringField
   code is not recognised as a bug and hence this change to align the behaviour.
   The TStringField change is expected in fpc 3.2.0.

2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
   true (default) then Size property value saved in the lfm is ignored. Size is
   always set from the dynamic information read from the database. It is unclear
   why anyone would want to override this and set Size to false.

3. ibxscript: should now handle correctly a Case..End statement within a procedure
   block.

4. IBDatabase: new property - CreateIfNotExists. If true and database does not
   exist when an attempt is made to connect to it (run time only) then an attempt
   is made to create the database.

5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
   has been successfully created as a result of a call to CreateDatabase or when
   creating a database after it was found not to exist.

6.  DBControlGrid: a race condition could result in the wrong row image being
    written to the cache. This has been avoided by a trip round the message
    loop before rendering the row image.

7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
    known to risk corrupt rendering of row images when the control is first
    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
    of the dataset (see DBControlGrid examples) until the Form's Window has been created.

8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
    a TDateEdit control located on an editor panel.

9.  TIBExtract: brought up-to-date plus many bug fixes.

10. DBControlGrid: Removed memory leak when updating rows.

11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100

1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
   when target codepage is CP_NONE. This is a workaround for
   http://bugs.freepascal.org/view.php?id=30622.

2. DBLog option removed from TIBStatisticalService - not supported by server
   since Firebird 1.5.

3. ibxscript: An error is no longer generated for "on commit preserve rows" or
   similar.

4. IBCodePage: updated mapping between codepages and character id.

5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
   Firebird. Character sets with a char width of two are not UTF16.

6. Strings received from the database are now always transliterated into UTF8
   regardless of the database character set or connection character set. This
   is for compatibility with the LCL.

IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100

1. IBBlob: Defer reading of blob until read method called. This avoids having to
   read in an entire blob just to get the size of the blob. General performance
   improvement when opening datasets containing blobs.

2. Clearing a  Blob now sets the corresponding field's modified flag.

3. IBLookupCombo: When not performing auto-complete, original query sort order
   is now used.

4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
   determined.

5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.

6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
   lazarus 1.6.0

7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
   compilation error.

IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100

1. No character set specified for connection: when a text blob is retrieved, the
  character set is determined by looking up the native character set using then
  Firebird API. Otherwise a text mode blob is assumed to have the same character
  set as the connection.

2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
   for Login Dialog returing a change to the database path.

3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
   to be changed from that given in the TIBDatabase/TIBServer component and for the
   entered value to be saved on a project specific basis (design time only).

4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
   column fieldname. If they are the same then it is acts as a look up for the KeyValue
   Otherwise, it sets the column text to the selected ListField Value.

5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
   column width.

6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
   and a case insensitive search is requested.

7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
   or column ListSource.

8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
   unprepare) when closing and the text has not changed.

9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
   Less likely to cause a cursor re-use error on Windows.

10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.

11. TIBTreeView: Guard against nil destination on record changed

12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
    string type with the code page set to reflect the returned field encoding after
    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for 
    earlier versions.

13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
    will now result in transliteration to the code page specified for the Firebird driver
    if the assigned string has a different code page. FPC 3.0.0 onwards only.

14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
    is ignored and the lc_ctype value, when the database is opened, is set to align with
    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
    the GETACP is used to determine the Windows code page.

15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
    name used as the lc_ctype when the database was opened. Only valid while the
    Database is connected.

16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
    id that corresponds to the DefaultCharSetName.

IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000

1. Unix: If Firebird Embedded Server shared object is loaded and a local database
   path is given and database attach fails due to access permission issues on the
   temp directory or security database, then the attach is retried with "localhost:"
   prefixing the databasename. This should avoid problems when the database has to
   be accessed by a local (e.g. classic) server and libfbembed is used.

2. Windows: revised search order for Firebird DLL:
     i.   The Firebird Embedded Server in the application Directory.
     ii.  If the FIREBIRD environment variable is set then the directory this
          points to is searched for the FB Client DLL and then then underlying
          "bin" directory.
     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
          is used to locate the Firebird installation directory and the underlying
          "bin" directory is searched for the FB Client DLL.
     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
          are searched for the FB Client DLL.
     v.   The PATH Environment variable is used to search for the FB Client DLL.
     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.

3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
   See doc/readme.scriptengine and example applications.

4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
   simplify the use of the embedded firebird server on both Linux and Windows platforms.
   See dpc/readme.localdatabase and example applications.

5. IBDynamicGrid: Reordering on column header click should now also work for
   dynamic columns.

6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
   between incrementing/decrementing the lock count and signalling the event.

IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000

1.3.2 was never formally released and only made available as beta copies.

1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo

2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column

3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early

4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
   i.e. when it is a calculated field

5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
   This problem was due to a race condition between recalculating row heights and
   determining which row was selected by the mouse click. The row height calculation
   is now deferred by an extra trip round the message loop allowing the row to
   be always calculated on the current grid layout rather than risking it being
   calculated on the grid layout after the expanded row has been shrunk.

6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
   Windows.

7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
   to be determined at runtime. See doc/readme.charactersets.html.

8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.

9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of 
   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.

   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
   implies no truncation.

10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.

11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
   (avoids "Not in Edit Mode" error).

12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.

13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.

14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.

15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls

16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.

17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100

1.   OnCloseUp Event Handler added to TDBLookupProperties

2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
     problem with row size when exception is called.

3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.

4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
     in a TCustomComboBox and ignores return key if in a TCustomMemo

5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
     keyed in i.e. when autocomplete not performed

6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
     console mode applications with all LCL required functions (builtin dialogs and
     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is 
     not included in your project, IBX should compile and link with a console mode program. 
     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a 
     console mode application or the IDE will automatically assume that your 
     application is GUI based. Instead, you should include the ibexpressconsolemode package.

     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order 
     to use the built in dialogs and cursor management. IBDialogs is
     included by default if "ibexpress" is in your project source's "uses" clause.
     This should be the case for all projects created through the IDE. This is why
     you do not want to add the ibexpress package to console mode applications. The
     ibexpressconsolemode package has been created to allow console mode programs
     to avoid adding LCL dependencies when using IBX, while still having the
     unit search paths set up correctly.

     Existing users should check to ensure that the "ibexpress" unit is included in
     each project's source file (*.lpr).

     You may find that in order for the IDE to recognise that ibexpressconsolemode
     exists, you have to first open the package in the IDE and then close it. This
     adds it to the most recently accessed packages list. To make it permanently
     available, add the package name to lazarus' staticpackages.inc file.

         Thanks to Julio Jiménez for suggesting support of console mode.

7.   SQL Parser can now accept quoted strings that include new lines

8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end 
     of text on start of edit. This is particularly useful when tabbing to a
     column and then inserting text.

9.   New Examples provided for IB Services and ISQLMonitor.

10. Fix error when writing to blob streams that recorded only the last buffer
    write in the blob stream. In most cases, this did not cause a problem as the
    IB Blob Stream is written in a single write. However, with the TDBImage, write
    of a graphic type prefix was lost which caused a problem when the image could
        not be automatically recognised.

11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
    already open" errors due to random numbers used for the cursor name being identical.

12. IBTable: corrected error that could result in an "Index out of bounds" error
    when opening the table and the Primary Key is the last or only column in the
    table. Thanks to Rick Hoover for the fix.

13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
    of "UTF-8", and update list of available database character sets. Existing
    users should check the current lc_ctype setting in their applications.

IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100

1.  Firebird Services: avoid List Index error when opening a service with an
    empty Params property.

2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
    Link now set up in Loaded method - avoids occasional failure to apply
    SQL markup on initial open.

3.  "Employees" example performance improvements when scrolling.

4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
    TFrame. Force recaching of selected frame to avoid GTK race (results in a
    random image cached).

5.  DBControlGrid: Should now react to changes in panel height at run time.

6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid   
    even when further rows exist.

7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
    always be derived from panel height and setting this property can cause confusion.
    Note for existing projects: to avoid a missing property error at run time,
    each form using the DBControlGrid must be opened, updated and saved in the IDE
    in order to remove the property value from the lfm.


IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100

1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
    call Prepare before setting parameter values.

2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.

3.  Code tidyup and more robust handling of dsql information result vector.

4.  Support for centralised handling of transaction status changes. TIBTransaction
    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
    and "AfterExecQuery". The first three are called after the same event is called
    for an IBCustomDataSet descendent using the Transaction. The fourth is called
    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
    enable monitoring of transaction status changes for a given transaction to be
    handled in a single place. For example, when a change to the dataset occurs
    an indicator can be set that shows the user that in order to save changes,
    the transaction should be committed.  Rather than doing this per dataset, this
    can now be done per transaction.

5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
    the dataset is scrolled. However, any changes to the current row are, by default,
    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
    have a new property "DataSetCloseAction" that adds automatic posting of changes
    on dataset close. If this property is set to dcDiscardChanges (default) then the
    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
    then IBX will attempt to post any unsaved changes before the dataset is closed
    (and after the BeforeClose event handler is called). The exception is when the
    dataset is being closed as a result of a transaction rollback. In this case,
    no action is taken and any unsaved  changes are discarded. This avoids both
    unnecessary overhead and the risk that a validation error may occur in the Post
    raising an exception and thereby preventing a rollback.

6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
    In earlier versions, the Display Width was set to the maximum byte width rather than the character
    width. Display Widths are now corrected by dividing by the max byte width per character.
    For UTF8 character sets, the byte width is four and hence the Display Width will be
    the byte width divided by 4. The byte width of each character set is determined
    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
    system table. (see also http://bugs.freepascal.org/view.php?id=27766).

7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.

8.  IBLookupComboEditBox: List should now always be restored to full list when the
    control loses focus. Default Key press default interval reduced to 200ms.

9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
    when dataset rows are less than visible rows.

10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
    does not exist or DataSet is empty. More responsive on dataset open. New event
    OnRestorePosition. Column sort disabled if no header row.

11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
    while dataset state is dsInsert. Avoids posting errors.

12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.

13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.

14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
    always "posts" the current record regardless or whether or not it may be more appropriate
    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
    as the first action of the "Post" method and allows the handler to convert the Post
    into a Cancel if that is the appropriate action on moving to a different row. This is
    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
    raised here, but it may still be more appropriate to validate a post and signal
    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)

15. On Unix derived systems, the Firebird library name can now be given as a colon
    separated list. Each library name on the list is tried in turn, in left to right
    order with the first found being used as the firebird library. By default, on Linux,
    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
    overidden by the FBLIB environment variable or the OnGetLibraryName function.

    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
    then it will still attempt to access the database via the Firebird Server and will
    require a username and password. If only the pathname is given, then the username
    and password should be omitted and the unix file permissions are used to grant
    access.

IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000

1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike 
    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid 
    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row 
    corresponds to a row of the linked DataSource. Any data aware control on the 
    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.

2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
   takes place during database access. This may be useful when there are performance issues with
   the change of cursor. Setting the property to false suppresses the change of cursor.

3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to 
   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
   making all changes permanent immediately rather than when the transaction is explicitly 
   committed.

4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000

Development version only.

IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000

1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
   This is typically used during an "OnBeforeOpen" event handler to manipulate the
   "Where" and "Having" clauses to implement user specified filters of arbitrary
   complexity.

2. A new Component Palette entry "Firebird Data Controls" is now available. This has
   three new data aware controls dependent on IBX and which make use of the SQL Parser.
   These are:

   - TIBLookupComboEditBox
   - TIBDynamicGrid
   - TIBTreeview

   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
   to revise the available list and restrict it to items that are prefixed by the
   typed text (either case sensitive or case insensitive). Autoinsert allows a
   newly typed entry to be added to the list dataset and included in the available
   list items.

   TIBDynamicGrid is a TDBGrid descendent that provides for:
   - automatic resizing of selected columns to fill the available row length
   - automatic positioning and sizing of a "totals" control, typically at the
     column footer, on a per column basis.
   - DataSet resorting on header row click, sorting the dataset by the selected column.
     A second click on the same header cell reversed the sort order.
   - Support for a "Panel Editor". That is on clicking the indicator column, the row
     is automatically expanded and a panel superimposed on it. The panel can have any
     number of child controls, typically data aware controls with the same datasource
     as the grid allowing for editing of additional fields and more complex editors.
   - Reselection of the same row following resorting.
   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
     Its properties are specified on a per column basis and allows for one or more
     columns to have their values selected from a list provided by a dataset.
     Autocomplete and autoinsert are also available. The existing picklist editor
     is unaffected by the extension.

   TIBTreeView is a data aware TCustomTreeView.

3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
   zero scale will no longer return an error. An Int64 will be returned instead.

4. TIBTransaction now has events for Before and After Transaction End and a new function
   "GetEndAction" allowing the EndAction to be accessed by these event handlers.

5. TIBQuery can now handle correctly queries which contain the same keyword parameter 
   repeated multiple times.

6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
   check used to get in the way of using Stored Procedures, and "Update or Insert"
   statements.

7. Insert, Modify and Delete property Editors now support Query Generation from
   Stored Procedures.

8. Three new examples illustrate the use of the new IB Controls


IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100

1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
   Gabor Boros for reporting this problem and for testing the improvements).

2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
   See readme.field+param.names in the doc folder.

3. IBX SQL Editors will now automatically add double quotes around column names when the database
   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.

4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc

5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
   actions.

6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
   thanks to Yuriy Kopnin for pointing this out).

7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.

8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
   for both fields and parameter setting.

9. Changes to the Select SQL in an IBCustomDataset descendent should now be
   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.

10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.

11. TIBTable now has a property editor for "MasterFields"

12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.

13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
    of settings is unrecognised. Selecting this radio button has no effect on the settings.
   

IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000

1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.

IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000

1. In a TIBCustomDataset descendent, a generator now only sets the value when
   it is null. This allows for alternative user defined setting of the generator

   Many thanks to Julio Jiménez for this fix

2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
   and suggests that the user may have forgotten to install it.

IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000

1. Conditional compilation used to limit registration of TIntegerField to
   Lazarus versions less than 1.1

2. When a database connection is created, character set is now by default set
   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
   1250 to 1254.


IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100

1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.


IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100

1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1

2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
   package is changed to do this (which it should do).

IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100

1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).

2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)

3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes

4. Property editors should now correctly resize.

5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
   (restored original functionality)

6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
