-IBX Change Log  version                           (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
+IBX Change Log  version                                     (2.2-0) Tue, 16 Jan 2018 16:49:07 +0000
+
+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 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.
+
+3. 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.
+
+4. TIBTable: The GeneratorField property is now published.
+
+5. 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.
+
+6. 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.
+
+7. TIBGenerator: small performance improvement by not preparing query each time
+   a new value is generated.
+
+8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
+
+9. 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.
+
+10. 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).
+
+11. 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).
+
+12. 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.
+
+13. 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.
+
+14. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
+    for password on reconnect.
