18 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
19 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
20 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
21 >      ISSUES TO support@mwasoftware.co.uk
22 >
23 > 1. Complete rewrite of internal buffer management in order to improve performance
24 >   and maintainability. Highlights:
25 >
26 >   * Extending the size of the buffer pool no longer has to copy the entire record
27 >     cache. Instead, a new extent is simply added to the buffer pool.
28 >   * A memory to memory copy of each display buffer now is avoided when scolling the
29 >     dataset.
30 >   * A separate set of buffers is now used for calculated fields. This avoids
31 >     having to keep copies of calculated field values in the buffer cache.
32 >   * Compact bitmaps are used to record null status and need to refresh in each
33 >     buffer.
34 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
35 >     buffer type in FCL-DB.
36 >
37 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
38 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
39 >
40 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
41 >   If either or both of these flags are set at design time (using the fields editor)
42 >   then this forces a row refresh on respectively insert or update, or both, when the
43 >   corresponding field is not present in an SQL RETURNING clause.
44 >
45 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
46 >   maintainability and readability and to add identification of primary key fields.
47 >
48 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
49 >   as a refresh of the current row. However, this is different behaviour to that described
50 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
51 >   the dataset from the underlying database, and attempts to reposition the cursor on
52 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
53 >
54 > 6. A progammatic Row Refresh should no longer be required.
55 >   Use Insert/Update... returning to refresh any fields that may change following an
56 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
57 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
58 >   for the field at Design Time to force a row refresh if not in the returning clause.
59 >
60 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
61 >
62 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
63 >   This gives the number of buffers in the initial block for the buffer pool in
64 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
65 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
66 >   for small datasets.

69 >
70 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
71 >
72 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
73 >
74 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
75 >
76 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
77 >
78 > 1. TIBTransaction: new properties
79 >    property TransactionID: integer read GetTransactionID;
80 >    property IsReadOnly: boolean read GetIsReadOnly;
81 >    {published}
82 >    property TransactionName: string read FTransactionName write SetTransactionName;
83 >
84 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
85 >   Insert or Update...Returning. This allows blobs and arrays to be returned
86 >   by the statement.
87 >
88 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
89 >
90 > 4. TransactionName initialised to a newly generated GUID if empty.
91 >
92 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
93 >   for the fbintf package's journaling capability. TIBJournal is used to set the
94 >   file path and filename for the journal file and to Enabled (start journaling) and
95 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
96 >   more information, and comments in IBJournal.pas.
97 >
98 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
99 >
100 > 7. Bug fix: blob id no longer set to null on update when blob has not been
101 >   retrieved.
102 >
103 > 8. Row auto refreshed on update/insert if blob or array field updated and field
104 >   not in a returning clause.
105 >
106 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
107 >   buffer overhead and avoids problem when refresh query has a different column
108 >   count to select query i.e. incorrectly changing number of columns.
109 >
110 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
111 >
112 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
113 >    string. Note that the Version property returns an InterBase compatible version string.
114 >
115 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
116 >

118 >
119 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
120 >   This is for compatibility with Firebird 5 where Update...Returning can return
121 >   a cursor.
