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.

69		1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
70		changes.
#	Line 17 | Line 83 | IBX Change Log  version
83		6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
84		entering a new name into the text box.
85
86	+	7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
87	+	Firebird rather than recomputing it.
88	+
89	+	8. Property Editor positioning tidy up: All IBX Property editors should now be
90	+	screen centre. Previously some were "poDesigned" which may be inappropriate
91	+	for multi monitor desktops.
92	+
93	+	10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
94	+
95	+	11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
96	+	a transaction and always reset the object.
97	+
98	+	12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
99	+
100	+	13. TIBXScript: Allow for override of database filename in Create Database statements.
101	+
102	+	14. IBLocaldb: Support initialisation of the database from an SQL script in addition
103	+	to a gbak format archive.
104	+
105	+	15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
106	+
107	+	16. IBLocaldb: Drop database if error creating an empty database.
108	+
109	+	17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
110	+	unless selected node not in current dataset.
111	+
112	+	18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
113	+	to TIBCustomService, and IBlocalDB code tidy up.
114	+
115	+	19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
116	+	behaviour due to uninitialised variable.
117	+
118	+	20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
119	+	integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
120	+
121	+	21. IBSQL: When Database changed ensure that all resources are freed.
122	+
123	+	22. IBCustomDataset: When database changed ensure that queries an unprepared.
124	+
125	+	23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
126	+	* Line Wrap on SQL Token boundaries (on user command)
127	+	* auto-complete table names in drop down list of table names
128	+	* Double click on tablename or field name adds to SQL text
129	+
130	+	24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
131	+
132	+	25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
133	+	TVariantArray. Seems to avoid memory corruption in Windows (probably a
134	+	workaround for a problem in fpc 3.0.4 win64).
135	+
136	+	26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
137	+
138	+	27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
139	+

142		1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
#	Line 37 | Line 157 | IBX Change Log  version
157		that BindFields is called when the query is next activated. Avoids FieldName
158		not found error.
159
160	+	7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
161	+	purpose and allows the programmer to define any action they want for Update, Insert
162	+	or Delete. This may be complex SQL (similar to a Trigger), application specific
163	+	filtering of updates, or use of statements such as Grant or Revoke instead of
164	+	normal DML. See User Manual for more information.
165	+

167
168		1. TIBEvents: Fix uninitialised variable that could result in lost events.
