2 >
3 > 1. Add try-..except check when initially loading library in IDE. This should
4 > ensure that IDE continues to load even when a failure occurs in IBX load
5 > library.
6 >
7 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 >   hence will correctly detect end of the outer containing block when the block
9 >   contains a SELECT ... CASE ... END construct.
10 >
11 > 3. IBExtract: some further tidying up to remove extraneous white space.
12 >
13 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
14 >
15 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
16 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
17 >
18 > 2. TIBSQL: Batch Update/Insert support added.
19 >
20 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
21 >   is no longer automatically converted to upper case when it is syntactically a
22 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
23 >   as CREATE PROCEDURE "iCASE".
24 >
25 >   There could be a backwards compatibility issue when the StoredProcName was entered
26 >   manually at design time. That is not selected from the drop down list. If the
27 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
28 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
29 >   ensure that the value of the StoredProcName is all upper case, unless it was
30 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
31 >   quotes).
32 >
33 >   Note that when a stored procedure name was declared delimited in double quotes,
34 >   as in the first example above, the value of the StoredProcName property must not
35 >   include the delimiters (double quotes).
36 >
37 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
38 >   upgrade.conf was not found. This replaces silently ignoring the problem.
39 >
40 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
41 >   'Version.%.3d' and is used to generate the section header names (for a given
42 >   version no.) in the upgrade.conf file.
43 >
44 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
45 >
46 > 1. -c command line option added to fbsql example program. Used to set connection
47 >   character set.
48 >
49 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
50 >
51 > 1. Firebird 4 support added.
52 >
53 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
54 >   extended precision NUMERIC fields are supported.
55 >
56 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
57 >
58 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
59 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
60 >
61 > 5. IBExtract now supports FB4 enhancements:
62 >   - new data types as above
63 >   - Identity column extensions
64 >   - Default user role
65 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
66 >   - Internal Functions
67 >
68 > 6. IBExtract: new event: OnExtractLines.
69 >
70 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
71 >
72 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
73 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
74 >
75 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
76 >   format for rendering a time zone.
77 >
78 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
79 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
80 >
81 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
82 >    IIBGUIInterface and IIBTimerInf respectively.
83 >
84 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
85 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
86 >
87 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
88 >    truncated to its fixed character width rather than being right padded with
89 >    white space to the maximum data size.
90 >
91 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
92 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
93 >    also empty.
94 >
95 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
96 >
97 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
98 >    connect string. The database name is extracted from the connect string.
99 >
100 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
101 >
102 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
103 >
104 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
105 >    not being present as required.
106 >
107 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
108 >    version that can be customised to work with other database drivers.
109 >
110 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
111 >    unnecessary CR at end of line on Unix platforms.
112 >
113 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
114 >    seconds in order to reduce risk of message loss.
115 >
116 > 23. ISQLMonitor: read and write count statistics now available via:
117 >      property TIBSQLMonitor.ReadCount;
118 >      IIBSQLMonitorHook.GetWriteCount: integer;
119 >
120 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
121 >

123 >
124 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
125 >    number of UTF8 characters exceeds the string size then string is truncated
126 >    to the maximum string size. This is  usually a problem with fixed width columns
127 >    right padded with white space.
128 >
129 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
130 >    If SQLFiltered is set then when a dataset is opened, each line in the
131 >    SQLFilterParams property is assumed to be a SQL condition clause and
132 >    ANDed into the Where clause of the SQL Select statement provided as a
133 >    dataset property. Each such SQL condition thus acts as an additional filter
134 >    on the dataset.
135 >
136 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
137 >    side filters).
138 >
139 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
140 >   text matches complete entry.
141 >
142 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
143 >   dataset are active (avoids risk of access violation if master is inactive)
144 >
145 > 6. TIBEvents: Registered property can now be set at design time even if database not open
146 >
147 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
148 >   This should prevent "spillover" of events between sessions.
149 >
150 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
151 >   This should ensure that the internal buffer is set up correctly and avoids
152 >   a duplicate initial row.
153 >
154 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
155 >   That is, the DataSize should be the field size * character set width. The
156 >   value returned by DataSize is now the same as the Dataset buffer size reserved
157 >   for the field.
158 >
159 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
160 >
161 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
162 >    and vice-versa. This may result in an exception being raised (correctly) for
163 >    older programs when using dataset fields added to a form and the database has been
164 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
165 >    In such cases, the field needs to be deleted in the IDE fields editor and then
166 >    added back in.
167 >
168 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
169 >    false if query contains only white space and not just empty.
170 >
171 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
172 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
173 >    is cancelled.
174 >
175 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
176 >    called on a null field.
177 >
178 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
179 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
180 > set.
181 >
182 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
183 >    a cached update is applied and an exception is raised.
184 >
185 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
186 >
187 > 17. Console Mode Local Database support: backup/restore should now work correctly.
188 >
189 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
190 >    possible and an exception raised.
191 >
192 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
193 >    below this version no. and upgrade not possible.
194 >
195 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
196  
197   1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
198      not SQL Identifiers are now supported.
