15     a returning clause that updates one or more fields on the current row. A full row
16     refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
17     field values and the select query contains read only fields. Use of Insert/update
18 <   returning should be significantly more efficient than excuting a refresh query.
18 >   returning should be significantly more efficient than executing a refresh query.
19  
20     This behaviour change is intended to be backwards compatible and there should be no need to change
21     existing programs, other than to improve performance by using the new capability.
22  
23 < 3. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
23 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
24 >   they are called when the dataset row is being deleted, there is no value in
25 >   updating the current record from the query result. Instead, a new event handler
26 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
27 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
28 >   by the query. The event handler can then interrogate the query results and
29 >   perform whatever action is necessary. For example to confirm, to the user,
30 >   the deletion of a row with the returned values.
31 >
32 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
33     any Computed By or Identity Columns. The IBTables example has been updated to
34     illustrate the computation of the employee Full Name on update.
35  
36 < 4. TIBTable: The GeneratorField property is now published.
36 > 5. TIBTable: The GeneratorField property is now published.
37  
38 < 5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
38 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
39     When InsertSQL is generated, the Identity columns are not included in the list of values to
40     be inserted. A RETURNING clause is added to the insert statement to return the value of
41     each Identity column after the insert is executed.
42  
43 < 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
43 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
44     Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
45     Insert..Returning clause.
46  
47 < 7. TIBGenerator: small performance improvement by not preparing query each time
47 > 8. TIBGenerator: small performance improvement by not preparing query each time
48     a new value is generated.
49  
50 < 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
50 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
51  
52 < 9. Property editors will now sync table name to a System Table when "Include System
53 <   Tables" is selected and the query is for a System Table.
52 > 10. Property editors will now sync table name to a System Table when "Include System
53 >    Tables" is selected and the query is for a System Table.
54  
55 < 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
55 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
56      values are no longer converted to milliseconds from TDateTime and then back again
57      to TDateTime (the conversion to milliseconds is the default TDataset approach).
58  
59 < 11. Property Editors handling of Stored Procedures.
59 > 12. Property Editors handling of Stored Procedures.
60      * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
61        which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
62        query).
63      * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
64  
65 < 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
65 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
66      can be used to select a package. If non-empty, the stored procedure name is
67      expected to be a stored procedure defined in the specified package and the
68      generated SQL will be as required for a stored procedure located in a package.
69  
70 < 13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
70 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
71      a "Package Name" drop down box to allow selection of a Firebird 3 Package from
72      which a stored procedure can be selected. With no package name selected, non-package
73      stored procedures are listed.
74  
75 < 14. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
75 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
76      for password on reconnect.
77  
78 + 16. IBDatabase: use IAttachment for connection default character set id, code page
79 +    and character set name.
80 +
81 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
82 +    DB info lookups"
83 +
84 + 18. IBExtract: now supports DDL Triggers.
