2 >
3 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 >    number of UTF8 characters exceeds the string size then string is truncated
5 >    to the maximum string size. This is  usually a problem with fixed width columns
6 >    right padded with white space.
7 >
8 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 >    If SQLFiltered is set then when a dataset is opened, each line in the
10 >    SQLFilterParams property is assumed to be a SQL condition clause and
11 >    ANDed into the Where clause of the SQL Select statement provided as a
12 >    dataset property. Each such SQL condition thus acts as an additional filter
13 >    on the dataset. (Not yet tested)
14 >
15 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 >    side filters).
17 >
18 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 >   text matches complete entry.
20 >
21 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 >   dataset are active (avoids risk of access violation if master is inactive)
23 >
24 > 6. TIBEvents: Registered property can now be set at design time even if database not open
25 >
26 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 >   This should prevent "spillover" of events between sessions.
28 >
29 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 >   This should ensure that the internal buffer is set up correctly and avoids
31 >   a duplicate initial row.
32 >
33 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 >   That is, the DataSize should be the field size * character set width. The
35 >   value returned by DataSize is now the same as the Dataset buffer size reserved
36 >   for the field.
37 >
38 > 10. IBExtact: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 >
40 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 >    and vice-versa. This may result in an exception being raised (correctly) for
42 >    older programs when using dataset fields added to a form and the database has been
43 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 >    In such cases, the field needs to be deleted in the IDE fields editor and then
45 >    added back in.
46 >
47 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
48 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
49 >    is cancelled.
50 >
51 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
52 >
53 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
54 >    not SQL Identifiers are now supported.
55 >
56 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
57 >    passed to the Firebird engine for execution.
58 >
59 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
60 >    is made to scroll back.
61 >
62 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
63 >
64 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
65 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
66 >
67 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
68 >   validated. If no match is found in the list of field names and the database has
69 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
70 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
71 >
72 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
73 >   with fpc 3.2.
74 >
75 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
76 >
77 >
78 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
79 >   and is used to override the default settings in the client side "firebird.conf" This
80 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
81 >   Each line of the string list should be a setting in the same format as "firebird.conf".
82 >   For example "WireCompression = true" in order to request wire compression on the client side.
83 >
84 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
85 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
86 >   also require a compatible setting in the server side "firebird.conf". For example
87 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
88 >   compression to be used.
89 >
90 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
91 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
92 >   ibx/examples/dbinfo for examples of how to display this information.
93 >
94 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
95 >   is a "convenience" property. If set the "WireCompression=true" is added to the
96 >   ConfigOverrides. If unchecked then this setting is removed.
97 >
98 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
99 >   not "INT64".
100 >
101 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
102 >   These are:
103 >    property TimestampFormat: string;
104 >    property DateFormat: string;
105 >    property TimeFormat: string;
106 >
107 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
108 >   DATETIME and TIME. The format strings use the standard FPC date/time format
109 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
110 >
111 >   If any of the above properties are set to an empty string, then the locale default
112 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
113 >   locale default is extended by appending '.zzz' to include milliseconds.
114 >
115 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
116 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
117 >
118 > 5. New published property for TIBCSVDataOut:
119 >     property QuoteStrings: boolean (default true)
120 >
121 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
122 >   used to delimit each and every string in the output.
123 >
124 > 6. New published properties for TIBCSVDataOut:
125 >    property FieldSeparator: string;
126 >    property HeaderSeparator: string;
127 >
128 >   Respectively, these provide the separator character(s) used to separate fields
129 >   in data and header rows. Both default to ','.
130 >
131 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
132 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
133 >    property OnFormatTextString;
134 >
135 >   This event handler can be used to process text strings before they are included
136 >   in the output e.g. to replace unprintable characters with alternative strings.
137 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
138 >
139 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
140 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
141 >   and without raising and exception if it does not.
142 >
143 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
144 >   consistency with SQL queries.
145 >
146 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
147 >    When true, SQL statement parameter names are parsed case sensitive. Note for
148 >    TIBDataSet only applies to Select query.
149 >
150 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
151 >    an IDE exception.
152 >
153 > 12. LocalDBSupport: initial database creation should now work correctly
154 >    when the schema source is an sql file.
155 >
156 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
157 >    when defined, this handler will be called by the internal TIBXScript during
158 >    initial database creation when the schema source is an sql file and may be used
159 >    to provide a visual indication of progress in console mode.
160 >
161 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
162 >    to true while a new local database is being created and its schema populated.
163 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
164 >    when the database is disconnected/connected during the create DB procedure.
165 >
166 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
167 >    are now always ignored and replaced by the user name and password provided as
168 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
169 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
170 >    completely ignored if this property is true.
171 >
172 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
173 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
174 >    ImageIndex and SelectImageIndex values on AddNode.
175 >
176 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
177 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
178 >    the same database connection.
179 >
180 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
181 >    if provided, this should be an conditional SQL expression suitable for
182 >    including in an SQL Select statement "where" clause. If non-empty and the
183 >    "Filtered" property is true then the SQL expression provided as the value of
184 >    the "Filter" property is "ANDed" with any existing condition statement
185 >    in the SQL statement's "Where" clause.
186 >
187 >    If the "Filter" property is set at run time, the "Filtered" property is true
188 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
189 >
190 >    The "Filter" condition may include IBX style parameters. In which case, their
191 >    value must be set by the dataset's "OnBeforeOpen" event handler.
192 >
193 >    This is a public property for TIBDataSet and TIBQuery query and intended for
194 >    use at run time.
195 >
196 >    Note: The property is a published property of TIBTable. The TIBTable functionality
197 >    is unaffected by this change.
