15 >   instead of zero. This is because Laz 3.0 changes the value of NullDate.

42 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
43 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
44 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
45 >      ISSUES TO support@mwasoftware.co.uk
46 >
47 > 1. Complete rewrite of internal buffer management in order to improve performance
48 >   and maintainability. Highlights:
49 >
50 >   * Extending the size of the buffer pool no longer has to copy the entire record
51 >     cache. Instead, a new extent is simply added to the buffer pool.
52 >   * A memory to memory copy of each display buffer now is avoided when scolling the
53 >     dataset.
54 >   * A separate set of buffers is now used for calculated fields. This avoids
55 >     having to keep copies of calculated field values in the buffer cache.
56 >   * Compact bitmaps are used to record null status and need to refresh in each
57 >     buffer.
58 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
59 >     buffer type in FCL-DB.
60 >
61 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
62 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
63 >
64 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
65 >   If either or both of these flags are set at design time (using the fields editor)
66 >   then this forces a row refresh on respectively insert or update, or both, when the
67 >   corresponding field is not present in an SQL RETURNING clause.
68 >
69 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
70 >   maintainability and readability and to add identification of primary key fields.
71 >
72 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
73 >   as a refresh of the current row. However, this is different behaviour to that described
74 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
75 >   the dataset from the underlying database, and attempts to reposition the cursor on
76 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
77 >
78 > 6. A progammatic Row Refresh should no longer be required.
79 >   Use Insert/Update... returning to refresh any fields that may change following an
80 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
81 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
82 >   for the field at Design Time to force a row refresh if not in the returning clause.
83 >
84 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
85 >
86 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
87 >   This gives the number of buffers in the initial block for the buffer pool in
88 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
89 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
90 >   for small datasets.
