->
+IBX Change Log  version (2.4-3 Build 12875) Sat, 23 Oct 2021 14:43:01 +0100
->
->
+. 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.
->
->
+. 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.
->
->
+. IBExtract: some further tidying up to remove extraneous white space.
->
->
+. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
->
+   errors when extra elements are added to DB.TFieldType.
->
->
+. IBUpdate: updated to reflect changes to ISQLParam.
->
->
+. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
->
->
+. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
->
->
+. 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
->
->
+. 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.
->
->
+. TIBSQL: Batch Update/Insert support added.
->
->
+. 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).
->
->
+. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
->
+   upgrade.conf was not found. This replaces silently ignoring the problem.
->
->
+. 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
->
->
+. -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
->
->
+. Firebird 4 support added.
->
->
+. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
->
+   extended precision NUMERIC fields are supported.
->
->
+. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
->
->
+. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
->
+   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
->
->
+. 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
->
->
+. IBExtract: new event: OnExtractLines.
->
->
+. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
->
->
+. 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"
->
->
+. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
->
+   format for rendering a time zone.
->
->
+. 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.
->
->
+. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
->
+    IIBGUIInterface and IIBTimerInf respectively.
->
->
+. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
->
+    now accessible as properties of TIBDatabase and TIBTransaction respectively.
->
->
+. 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.
->
->
+. 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.
->
->
+. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
->
->
+. TIBXControlService descendents: DatabaseName may now be set using a database
->
+    connect string. The database name is extracted from the connect string.
->
->
+. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
->
->
+. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
->
->
+. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
->
+    not being present as required.
->
->
+. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
->
+    version that can be customised to work with other database drivers.
->
->
+. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
->
+    unnecessary CR at end of line on Unix platforms.
->
->
+. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
->
+    seconds in order to reduce risk of message loss.
->
->
+. ISQLMonitor: read and write count statistics now available via:
->
+      property TIBSQLMonitor.ReadCount;
->
+      IIBSQLMonitorHook.GetWriteCount: integer;
->
->
+. 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
->
->
+.  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.
->
->
+.  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.
->
->
+.  The Filtered property inherited from TDataset is no longer used for SQL (server
->
+    side filters).
->
->
+. IBLookupComboEditBox: Selection should no longer reset to start of text when
->
+   text matches complete entry.
->
->
+. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
->
+   dataset are active (avoids risk of access violation if master is inactive)
->
->
+. TIBEvents: Registered property can now be set at design time even if database not open
->
->
+. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
->
+   This should prevent "spillover" of events between sessions.
->
->
+. 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.
->
->
+. 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.
->
->
+. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
->
->
+. 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.
->
->
+. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
->
+    false if query contains only white space and not just empty.
->
->
+. 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.
->
->
+. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
->
+    called on a null field.
->
->
+. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
->
+    results in an empty dataTC86                Client side Filtered Dataset    1       X
->
+set.
->
->
+. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
->
+    a cached update is applied and an exception is raised.
->
->
+. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
->
->
+. Console Mode Local Database support: backup/restore should now work correctly.
->
->
+. Local Database Support: if an upgrade fails, a downgrade is now performed if
->
+    possible and an exception raised.
->
->
+. 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
->
->
+.  TIBXDataSet and Generators: Generator Names that are not all upper case or
->
+    not SQL Identifiers are now supported.
->
->
+.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
->
+    passed to the Firebird engine for execution.
->
->
+.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
->
+    is made to scroll back.
->
->
+.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
->
->
+. 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.
->
->
+. 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.
->
->
+. 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
->
->
->
+. 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.
->
->
+. 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.
->
->
+. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
->
+   not "INT64".
->
->
+. 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.
->
->
+. 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.
->
->
+. 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 ','.
->
->
+. 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.
->
->
+. 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.
->
->
+. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
->
+   consistency with SQL queries.
->
->
+. 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.
->
->
+. IBEvents: removing a TIBEvent component from a form should no longer result in
->
+    an IDE exception.
->
->
+. LocalDBSupport: initial database creation should now work correctly
->
+    when the schema source is an sql file.
->
->
+. 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.
->
->
+. 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.
->
->
+. 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.
->
->
+. 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.
->
->
+. 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.
->
->
+. 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
->
->
+. 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.
->
->
+. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
->
+   statement. This avoids problems if "Execute Block" is used as the Query.
->
->
+. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
->
+   internal SQL tokeniser routines.
->
->
+. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
->
+   as a select statement, with or without CTEs.
->
->
+. IBSQLParser: parser now recognises the "ROWS" clause.
->
->
+. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
->
+   internal SQL tokeniser routines.
->
->
+.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
->
+    being raised for valid set statements processed by a data formatter.
->
->
+. 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.
->
->
+. New read only public property for TIBDatabase and TIBXServicesConnection. This
->
+   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
->
+   services connection.
->
->
+.SQL Property editors now quote parameter names if "Quote identifier" is selected
->
+   or param name is not a valid SQL identifier.
->
->
+. 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.
->
->
+. 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
->
->
+. 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.
+    with Extract Option eoDatabase.
+. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
-<
+    When a deLaoutChanged event is reported on the ListSource dataset, the
->
+    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).
-+
+. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
-+
-+
+. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
-+
+    stubs. Pedantic fix really, as procedures output in dependency order anyway.
-+
-+
+. TIBExtract: Package Headers and Package Bodies are now included in the extracted
-+
+    DDL (Firebird 3 and later only).
-+
-+
+. 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.
-+
-+
+. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
-+
+    between SQL statements.
-+
-+
+. 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.
-+
-+
+. 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.
-+
-+
+. TIBXScript: If an exception occurs during the processing of a statement, the
-+
+    statement separate character is now reset to the default (';').
-+
-+
+. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
-+
-+
+. TIBXScript: Transaction is no longer automatically reactivated immediately processing
-+
+    a commit or reconnect statement and instead activated only when next SQL statement
-+
+    is executed.
-+
-+
+. TIBSQL.HasField should no longer generate and exception when the field does not exist.
-+
-+
+. TIBXScript: case insensitive regex now used when matching statements instead of
-+
+    converting statement to upper case.
-+
-+
+. 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.
-+
-+
+. TIBExtract: ListObjectNames method added.
-+
-+
+. Updated Database component editor to support additional connection string
-+
+    types.
