1 + IBX Change Log  version                                (2.1-1) Fri, 05 Jan 2018 16:53:58 +0000
2 +
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 + IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
16 +
17 + 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
18 +   changes.
19 +
20 + 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
21 +   Bug could result in truncated multi-byte character set values.
22 +
23 + 3. Changes consequential on moving fbintf character set utility functions from
24 +   IFirebirdAPI to IAttachment.
25 +
26 + 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
27 +
28 + 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
29 +   results in autocomplete ignoring prefix text.
30 +
31 + 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
32 +   entering a new name into the text box.
33 +
34 + 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
35 +   Firebird rather than recomputing it.
36 +
37 + 8. Property Editor positioning tidy up: All IBX Property editors should now be
38 +   screen centre. Previously some were "poDesigned" which may be inappropriate
39 +   for multi monitor desktops.
40 +
41 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
42 +
43 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
44 +    a transaction and always reset the object.
45 +
46 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
47 +
48 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
49 +
50 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
51 +    to a gbak format archive.
52 +
53 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
54 +
55 + 16. IBLocaldb: Drop database if error creating an empty database.
56 +
57 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
58 +    unless selected node not in current dataset.
59 +
60 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
61 +    to TIBCustomService, and IBlocalDB code tidy up.
62 +
63 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
64 +    behaviour due to uninitialised variable.
65 +
66 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
67 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
68 +
69 + 21. IBSQL: When Database changed ensure that all resources are freed.
70 +
71 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
72 +
73 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
74 +    * Line Wrap on SQL Token boundaries (on user command)
75 +    * auto-complete table names in drop down list of table names
76 +    * Double click on tablename or field name adds to SQL text
77 +
78 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
79 +
80 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
81 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
82 +    workaround for a problem in fpc 3.0.4 win64).
83 +
84 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
85 +
86 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
87 +
88 + IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
89 +
90 + 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
91 +   include remote system name.
92 +
93 + 2. TIBExtract: No longer include comment header and COMMIT statement for empty
94 +   tables when data included in output.
95 +
96 + 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
97 +   and timing information to be written to stdout. This may be used to locate
98 +   performance bottlenecks.
99 +
100 + 4. SQLParser: only call "OnChanging" event handler when value is different.
101 +
102 + 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
103 +
104 + 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
105 +   that BindFields is called when the query is next activated. Avoids FieldName
106 +   not found error.
107 +
108 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
109 +   purpose and allows the programmer to define any action they want for Update, Insert
110 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
111 +   filtering of updates, or use of statements such as Grant or Revoke instead of
112 +   normal DML. See User Manual for more information.
113 +
