+IBX Change Log  version (2.3-5 Build 12341) Mon, 24 Aug 2020 10:23:35 +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. (Not yet tested)
-+
-+
+.  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.
-+
-+
+. IBExtact: 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: 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.
-+
-+
+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
