3 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
4 >
5 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
6 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
7 >   information). However, this is also a very useful mechanism for returning updated computed by
8 >   column values. Values returned as a result of executing an Insert or Update statement
9 >   replace existing values in the current row for each corresponding column.
10 >
11 >   Previously, if a dataset's select query included read only (computed by) fields then
12 >   an automatic row refresh was performed after an insert or update query had been processed,
13 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
14 >   that an automatic refresh is no longer performed if an insert or update query contains
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.
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
24 >   any Computed By or Identity Columns. The IBTables example has been updated to
25 >   illustrate the computation of the employee Full Name on update.
26 >
27 > 4. TIBTable: The GeneratorField property is now published.
28 >
29 > 5. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
30 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
31 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
32 >   each Identity column after the insert is executed.
33 >
34 > 6. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
35 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
36 >   Insert..Returning clause.
37 >
38 > 7. TIBGenerator: small performance improvement by not preparing query each time
39 >   a new value is generated.
40 >
41 > 8. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
42 >
43 > 9. Property editors will now sync table name to a System Table when "Include System
44 >   Tables" is selected and the query is for a System Table.
45 >
46 > 10. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
47 >    values are no longer converted to milliseconds from TDateTime and then back again
48 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
49 >
50 > 11. Property Editors handling of Stored Procedures.
51 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
52 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
53 >      query).
54 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
55 >
56 > 12. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
57 >    can be used to select a package. If non-empty, the stored procedure name is
58 >    expected to be a stored procedure defined in the specified package and the
59 >    generated SQL will be as required for a stored procedure located in a package.
60 >
61 > 13. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
62 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
63 >    which a stored procedure can be selected. With no package name selected, non-package
64 >    stored procedures are listed.
65 >
66 > 14. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
67 >    for password on reconnect.
68 >

128 < 23. SQL Property Editors now use SynEdit with SQL Highlighter.
128 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
129 >    * Line Wrap on SQL Token boundaries (on user command)
130 >    * auto-complete table names in drop down list of table names
131 >    * Double click on tablename or field name adds to SQL text
132  
133   24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
