+IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
-+
-+
+. Maintenance update of 2.6.0. This version is still at beta.
-+
-+
+. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
-+
+   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
-+
-+
+. 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
-+
-+
+. 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.
-+
-+
+. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
-+
+   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
-+
-+
+. 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.
-+
-+
+. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
-+
+   maintainability and readability and to add identification of primary key fields.
-+
-+
+. 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.
-+
-+
+. 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.
-+
-+
+. It should now be possible to insert a row into an empty unidirectional dataset.
-+
-+
+. 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
-+
-+
+. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
-+
-+
+. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
-+
-+
+. 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
-+
-+
+. TIBTransaction: new properties
-+
+    property TransactionID: integer read GetTransactionID;
-+
+    property IsReadOnly: boolean read GetIsReadOnly;
-+
+    {published}
-+
+    property TransactionName: string read FTransactionName write SetTransactionName;
-+
-+
+. 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.
-+
-+
+. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
-+
-+
+. TransactionName initialised to a newly generated GUID if empty.
-+
-+
+. 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.
-+
-+
+. TIBDatabase.InternalTransaction is now a read only transaction.
-+
-+
+. Bug fix: blob id no longer set to null on update when blob has not been
-+
+   retrieved.
-+
-+
+. Row auto refreshed on update/insert if blob or array field updated and field
-+
+   not in a returning clause.
-+
-+
+. 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.
-+
-+
+. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
-+
-+
+. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
-+
+    string. Note that the Version property returns an InterBase compatible version string.
-+
-+
+. 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
-+
-+
+. 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
-+
-+
+. 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.
