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.

7 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
8 >
9 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
10 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
11 >
12 > 2. TIBSQL: Batch Update/Insert support added.
13 >
14 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
15 >   is no longer automatically converted to upper case when it is syntactically a
16 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
17 >   as CREATE PROCEDURE "iCASE".
18 >
19 >   There could be a backwards compatibility issue when the StoredProcName was entered
20 >   manually at design time. That is not selected from the drop down list. If the
21 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
22 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
23 >   ensure that the value of the StoredProcName is all upper case, unless it was
24 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
25 >   quotes).
26 >
27 >   Note that when a stored procedure name was declared delimited in double quotes,
28 >   as in the first example above, the value of the StoredProcName property must not
29 >   include the delimiters (double quotes).
30 >
31 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
32 >   upgrade.conf was not found. This replaces silently ignoring the problem.
33 >
34 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
35 >   'Version.%.3d' and is used to generate the section header names (for a given
36 >   version no.) in the upgrade.conf file.
37 >
38 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
39 >
40 > 1. -c command line option added to fbsql example program. Used to set connection
41 >   character set.
42 >
43 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
44 >
45 > 1. Firebird 4 support added.
46 >
47 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
48 >   extended precision NUMERIC fields are supported.
49 >
50 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
51 >
52 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
53 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
54 >
55 > 5. IBExtract now supports FB4 enhancements:
56 >   - new data types as above
57 >   - Identity column extensions
58 >   - Default user role
59 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
60 >   - Internal Functions
61 >
62 > 6. IBExtract: new event: OnExtractLines.
63 >
64 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
65 >
66 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
67 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
68 >
69 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
70 >   format for rendering a time zone.
71 >
72 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
73 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
74 >
75 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
76 >    IIBGUIInterface and IIBTimerInf respectively.
77 >
78 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
79 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
80 >
81 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
82 >    truncated to its fixed character width rather than being right padded with
83 >    white space to the maximum data size.
84 >
85 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
86 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
87 >    also empty.
88 >
89 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
90 >
91 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
92 >    connect string. The database name is extracted from the connect string.
93 >
94 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
95 >
96 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
97 >
98 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
99 >    not being present as required.
100 >
101 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
102 >    version that can be customised to work with other database drivers.
103 >
104 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
105 >    unnecessary CR at end of line on Unix platforms.
106 >
107 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
108 >    seconds in order to reduce risk of message loss.
109 >
110 > 23. ISQLMonitor: read and write count statistics now available via:
111 >      property TIBSQLMonitor.ReadCount;
112 >      IIBSQLMonitorHook.GetWriteCount: integer;
113 >
114 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
115 >
116 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
117 >
118 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
119 >    number of UTF8 characters exceeds the string size then string is truncated
120 >    to the maximum string size. This is  usually a problem with fixed width columns
121 >    right padded with white space.
122 >
123 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
124 >    If SQLFiltered is set then when a dataset is opened, each line in the
125 >    SQLFilterParams property is assumed to be a SQL condition clause and
126 >    ANDed into the Where clause of the SQL Select statement provided as a
127 >    dataset property. Each such SQL condition thus acts as an additional filter
128 >    on the dataset.
129 >
130 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
131 >    side filters).
132 >
133 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
134 >   text matches complete entry.
135 >
136 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
137 >   dataset are active (avoids risk of access violation if master is inactive)
138 >
139 > 6. TIBEvents: Registered property can now be set at design time even if database not open
140 >
141 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
142 >   This should prevent "spillover" of events between sessions.
143 >
144 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
145 >   This should ensure that the internal buffer is set up correctly and avoids
146 >   a duplicate initial row.
147 >
148 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
149 >   That is, the DataSize should be the field size * character set width. The
150 >   value returned by DataSize is now the same as the Dataset buffer size reserved
151 >   for the field.
152 >
153 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
154 >
155 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
156 >    and vice-versa. This may result in an exception being raised (correctly) for
157 >    older programs when using dataset fields added to a form and the database has been
158 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
159 >    In such cases, the field needs to be deleted in the IDE fields editor and then
160 >    added back in.
161 >
162 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
163 >    false if query contains only white space and not just empty.
164 >
165 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
166 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
167 >    is cancelled.
168 >
169 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
170 >    called on a null field.
171 >
172 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
173 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
174 > set.
175 >
176 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
177 >    a cached update is applied and an exception is raised.
178 >
179 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
180 >
181 > 17. Console Mode Local Database support: backup/restore should now work correctly.
182 >
183 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
184 >    possible and an exception raised.
185 >
186 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
187 >    below this version no. and upgrade not possible.
188 >
189 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
190 >
191 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
192 >    not SQL Identifiers are now supported.
193 >
194 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
195 >    passed to the Firebird engine for execution.
196 >
197 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
198 >    is made to scroll back.
199 >
200 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
201 >
202 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
203 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
204 >
205 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
206 >   validated. If no match is found in the list of field names and the database has
207 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
208 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
209 >
210 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
211 >   with fpc 3.2.
212 >
213 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
