+IBX Change Log  version                                     (2.2-0) Tue, 16 Jan 2018 16:49:07 +0000
-+
-+
+. IBExtract: Identity columns - add additional check for null column for generator name.
-+
-+
+. 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 excuting 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.
-+
-+
+. 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.
-+
-+
+. TIBTable: The GeneratorField property is now published.
-+
-+
+. 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.
-+
-+
+. 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.
-+
-+
+. TIBGenerator: small performance improvement by not preparing query each time
-+
+   a new value is generated.
-+
-+
+. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
-+
-+
+. 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.
-+
-+
+. 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).
-+
-+
+. 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).
-+
-+
+. 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.
-+
-+
+. 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.
-+
-+
+. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
-+
+    for password on reconnect.
-+
-+
-+
+IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
-+
-+
+. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
-+
+   changes.
-+
-+
+. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
-+
+   Bug could result in truncated multi-byte character set values.
-+
-+
+. Changes consequential on moving fbintf character set utility functions from
-+
+   IFirebirdAPI to IAttachment.
-+
-+
+. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
-+
-+
+. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
-+
+   results in autocomplete ignoring prefix text.
-+
-+
+. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
-+
+   entering a new name into the text box.
-+
-+
+. IBCustomDataset: ensure that TIBStringField uses the field size reported by
-+
+   Firebird rather than recomputing it.
-+
-+
+. 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.
-+
-+
+. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
-+
-+
+. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
-+
+    a transaction and always reset the object.
-+
-+
+. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
-+
-+
+. TIBXScript: Allow for override of database filename in Create Database statements.
-+
-+
+. IBLocaldb: Support initialisation of the database from an SQL script in addition
-+
+    to a gbak format archive.
-+
-+
+. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
-+
-+
+. IBLocaldb: Drop database if error creating an empty database.
-+
-+
+. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
-+
+    unless selected node not in current dataset.
-+
-+
+. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
-+
+    to TIBCustomService, and IBlocalDB code tidy up.
-+
-+
+. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
-+
+    behaviour due to uninitialised variable.
-+
-+
+. 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.
-+
-+
+. IBSQL: When Database changed ensure that all resources are freed.
-+
-+
+. IBCustomDataset: When database changed ensure that queries an unprepared.
-+
-+
+. 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
-+
-+
+. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
-+
-+
+. 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).
-+
-+
+. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
-+
-+
+. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
-+
-+
+IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
-+
-+
+. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
-+
+   include remote system name.
-+
-+
+. TIBExtract: No longer include comment header and COMMIT statement for empty
-+
+   tables when data included in output.
-+
-+
+. 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.
-+
-+
+. SQLParser: only call "OnChanging" event handler when value is different.
-+
-+
+. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
-+
-+
+. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
-+
+   that BindFields is called when the query is next activated. Avoids FieldName
-+
+   not found error.
-+
-+
+. 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
-+
-+
+. TIBEvents: Fix uninitialised variable that could result in lost events.
-+
-+
+. TIBExtract: Added support for FB3 "USAGE" privilege.
-+
-+
+. TIBExtract: data formatted as Charset set "octets" is now output using
-+
+   hexadecimal notation.
-+
-+
+. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
-+
+   using a simple XML format.
-+
-+
+. TIBExtract: extract of individual Triggers and Stored Procedures can now include
-+
+   grants to these objects.
-+
-+
+. TIBExtract: Stored Procedures and Views output in dependency order to avoid
-+
+   dependency problems restoring complex databases.
-+
-+
+. 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.
-+
-+
+. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
-+
-+
+. 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>
-+
-+
+. IBVersion unit added to hold current IBX Version Number information.
-+
-+
+. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
-+
+    and domain definitions.
-+
-+
+. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
-+
+    fully supported.
-+
-+
+. TIBExtract: when a database dump includes data, the generator values are now also set.
-+
-+
+: 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.
-+
-+
+. 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.
-+
-+
+. 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.
-+
-+
+. ibxscript: should now handle correctly a Case..End statement within a procedure
-+
+   block.
-+
-+
+. 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.
-+
-+
+. 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.
-+
-+
+.  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.
-+
-+
+.  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.
-+
-+
+.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
-+
+    a TDateEdit control located on an editor panel.
-+
-+
+.  TIBExtract: brought up-to-date plus many bug fixes.
-+
-+
+. DBControlGrid: Removed memory leak when updating rows.
-+
-+
+. TIBCMLocalDBSupport: fixed invalid free on upgrade.

+IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
+. IBCustomDataset: When calling SetCodePage, no longer request transliteration
+   regardless of the database character set or connection character set. This
+   is for compatibility with the LCL.

+. 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
