3 < 1. TIBDatabase.CreateDatabase: extract full DB Name using reg ex in order to
3 > 1. IBExtract: Identity columns - add addition 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). Values returned as a result of executing an Insert or Update statement
8 >   replace existing values in the current row for each corresponding column.
9 >
10 > 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
11 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
12 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
13 >   each Identity column after the insert is executed.
14 >
15 > 4. TIBGenerator: small performance improvement by not preparing query each time
16 >   a new number is generated.
17 >
18 > 5. TIBSQL: Free resources when transaction changed.
19 >
20 > 6. Property editor will now sync table name to a System Table when "Include System
21 >   Tables" is selected and the query is for a System Table.
22 >
23 > 7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
24 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
25 >   Insert..Returning clause.
26 >
27 > 8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
28 >   values are no longer converted to milliseconds from TDateTime and then back again
29 >   the TDateTime (the TDataset approach).

32 >
33 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
34 >   changes.
35 >
36 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
37 >   Bug could result in truncated multi-byte character set values.
38 >
39 > 3. Changes consequential on moving fbintf character set utility functions from
40 >   IFirebirdAPI to IAttachment.
41 >
42 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
43 >
44 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
45 >   results in autocomplete ignoring prefix text.
46 >
47 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
48 >   entering a new name into the text box.
49 >
50 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
51 >   Firebird rather than recomputing it.
52 >
53 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
54 >   screen centre. Previously some were "poDesigned" which may be inappropriate
55 >   for multi monitor desktops.
56 >
57 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
58 >
59 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
60 >    a transaction and always reset the object.
61 >
62 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
63 >
64 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
65 >
66 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
67 >    to a gbak format archive.
68 >
69 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
70 >
71 > 16. IBLocaldb: Drop database if error creating an empty database.
72 >
73 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
74 >    unless selected node not in current dataset.
75 >
76 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
77 >    to TIBCustomService, and IBlocalDB code tidy up.
78 >
79 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
80 >    behaviour due to uninitialised variable.
81 >
82 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
83 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
84 >
85 > 21. IBSQL: When Database changed ensure that all resources are freed.
86 >
87 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
88 >
89 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
90 >    * Line Wrap on SQL Token boundaries (on user command)
91 >    * auto-complete table names in drop down list of table names
92 >    * Double click on tablename or field name adds to SQL text
93 >
94 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
95 >
96 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
97 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
98 >    workaround for a problem in fpc 3.0.4 win64).
99 >
100 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
101 >
102 > 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

106 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
107     include remote system name.
108  
109   2. TIBExtract: No longer include comment header and COMMIT statement for empty

117  
118   5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
119  
120 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
121 +   that BindFields is called when the query is next activated. Avoids FieldName
122 +   not found error.
123 +
124 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
125 +   purpose and allows the programmer to define any action they want for Update, Insert
126 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
127 +   filtering of updates, or use of statements such as Grant or Revoke instead of
128 +   normal DML. See User Manual for more information.
