3 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
4 > all previous copies of the IBX source code tree before installing this release.
5 >
6 > The IBX packages used by most users have not changed, with one exception. The
7 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
8 > to use the IBServices unit in your applications, please add the iblegacyServices
9 > to the list of dependencies. To do this, open the Project Inspector and select
10 > Add->New Requirement and select "ibLegacyServices" from the list of available
11 > packages.
12 >
13 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
14 >   the IBServices unit providing what is intended to be a clearer and easier to
15 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
16 >   more information and the guide to "Firebird Service Management Using IBX".
17 >   As indicated above, the legacy services components are still available and
18 >   provided in a separate package. There is no need to update working applications
19 >   using the older versions except for an additional package dependency.
20 >
21 > 2. The IBX packages and source code tree have been re-organised in an attempt to
22 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
23 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
24 >   new set of IBX packages.
25 >
26 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
27 >   updated to use the new Services API components.
28 >
29 > 4. The iblocal package has been updated to use the new Services API components.
30 >
31 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
32 >   TIBXSecurityService. It had been wrongly classified in the previous version
33 >   as a per database configuration item. It is global to a server and hence
34 >   correctly positioned as part of the Security Package. In the DBAdmin example,
35 >   the setting has moved to the mappings page.
36 >
37 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
38 >   are ignored.
39 >
40 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
41 >   closed before the database is dropped. Before and After Disconnect event handlers
42 >   are also fired.
43 >
44 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
45 >   is started and not just the first time.
46 >
47 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
48 >   depenendency with comp type.
49 >
50 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
51 >
52 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
53 >    then this is recognised and not ignored.
54 >
55 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
56 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
57 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
58 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
59 >
60 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
61 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
62 >    counters for the select query. Note: stats accumulate after each fetch from
63 >    the database. To get total query cost after open, call the "Last" method
64 >    and then GetPerfStatistics.
65 >
66 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
67 >
68 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
69 >    in parenthesises.
70 >
71 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
72 >    SQL identifiers are always delimited by double quotes. If false, then they are
73 >    only delimited if the identifier is a reserved word, contains lower case or special
74 >    characters. Set this property to true to retain previous behaviour.
75 >
76 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
77 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
78 >
79 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
80 >       property MasterDetailDelay: integer {defaults to zero}
81 >
82 >    When non-zero and the dataset is a detail table referencing a master table
83 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
84 >    then a synchronisation delay is added (in milliseconds) between the master
85 >    row changing and the detail dataset being re-opened. If the master dataset
86 >    is scrolled before the delay expires then the delay is reset. This can be used
87 >    to avoid performance overheads when scrolling through a large master dataset.
88 >
89 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
90 >    chreads unit must be included in your project. TTimer is not used in order
91 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
92 >
93 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
94 >    with Extract Option eoDatabase.
95 >
96 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
97 >    When a deLaoutChanged event is reported on the ListSource dataset, the
98 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
99 >    relationship with the control's datasource (master).

102 >
103 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
104 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
105 > RELEASE.
106 >
107 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.

199      is a System Table.

201 < 22. IBServices: SQRB and SRB buffers are now reset when service query throws and exception.
201 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
202      This avoids errors due to a stale SQRB or SRB being used for the next query.

204   23. IBServices: Service attach parameters now include "expected_db". This is used to

214   26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
215      databasenames. These are respectively expanded to the local system's temp directory
216 <    (including trailing delimiter) or to a directory a prescribed data directory (including
216 >    (including trailing delimiter) or to a prescribed data directory (including
217      trailing delimiter). Under Unix systems the data directory is a hidden directory
218      in the user's home directory. The hidden directory name is either the string returned
219      from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
220      Under Windows, the directory is the same as the Data Directory as decribed
221      above but instead prefixed by the User's application data path. These may be
222 <    used to improve application portability.
222 >    used to improve application portability for Personal Databases.
223  
224   27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
225      this has not worked for a long time and is not useful either. FieldDefs should be
