2
3	<	This is rc1 for 2.2.3.
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	<	1. New property for TIBDatabase and TIBXServicesConnection. This is "WireCompression".
9	<	If this property is set to true then the Client will request WireCompression for
10	<	the connection. Note: "WireCompression = true" must be set in the server's
11	<	"firebird.conf". This property is overridden if "WireCompression = true" is set
12	<	in the client "firebird.conf" when wire compression is always requested by the client.
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	<	IBX Change Log  version                   (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
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. IBExtract: 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: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
48	>	false if query contains white space and not just empty.
49	>
50	>	12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
51	>	should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
52	>	is cancelled.
53	>
54	>	IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
55	>
56	>	1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
57	>	not SQL Identifiers are now supported.
58	>
59	>	2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
60	>	passed to the Firebird engine for execution.
61	>
62	>	3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
63	>	is made to scroll back.
64	>
65	>	4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
66	>
67	>	5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
68	>	only enclosed in double quotes in SQL dialect 3 and when it needs to be.
69	>
70	>	6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
71	>	validated. If no match is found in the list of field names and the database has
72	>	been opened in SQL Dialect 3, then the ListField Name is converted to upper case
73	>	if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
74	>
75	>	7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
76	>	with fpc 3.2.
77	>
78	>	IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
79	>
80	>
81	>	1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
82	>	and is used to override the default settings in the client side "firebird.conf" This
83	>	includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
84	>	Each line of the string list should be a setting in the same format as "firebird.conf".
85	>	For example "WireCompression = true" in order to request wire compression on the client side.
86	>
87	>	Note: explicit settings in the client side "firebird.conf" appear to take precedence
88	>	over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
89	>	also require a compatible setting in the server side "firebird.conf". For example
90	>	"WireCompression = true" must also be set in the server's "firebird.conf" for wire
91	>	compression to be used.
92	>
93	>	Whether or not WireCompression or WireCrypt are in use can be checked using the information
94	>	returned with the Client/Server protocol version. See ibx/examples/dbadmin and
95	>	ibx/examples/dbinfo for examples of how to display this information.
96	>
97	>	2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
98	>	is a "convenience" property. If set the "WireCompression=true" is added to the
99	>	ConfigOverrides. If unchecked then this setting is removed.
100	>
101	>	3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
102	>	not "INT64".
103	>
104	>	4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
105	>	These are:
106	>	property TimestampFormat: string;
107	>	property DateFormat: string;
108	>	property TimeFormat: string;
109	>
110	>	Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
111	>	DATETIME and TIME. The format strings use the standard FPC date/time format
112	>	characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
113	>
114	>	If any of the above properties are set to an empty string, then the locale default
115	>	is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
116	>	locale default is extended by appending '.zzz' to include milliseconds.
117	>
118	>	TIBCSVDataOut by default sets these properties to the empty string, while the other
119	>	two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
120	>
121	>	5. New published property for TIBCSVDataOut:
122	>	property QuoteStrings: boolean (default true)
123	>
124	>	If false then strings are unquoted, otherwise, the QuoteChar property value is
125	>	used to delimit each and every string in the output.
126	>
127	>	6. New published properties for TIBCSVDataOut:
128	>	property FieldSeparator: string;
129	>	property HeaderSeparator: string;
130	>
131	>	Respectively, these provide the separator character(s) used to separate fields
132	>	in data and header rows. Both default to ','.
133	>
134	>	7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
135	>	TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
136	>	property OnFormatTextString;
137	>
138	>	This event handler can be used to process text strings before they are included
139	>	in the output e.g. to replace unprintable characters with alternative strings.
140	>	This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
141	>
142	>	8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
143	>	Uses "FindParam" if in order to find out if a parameter with a given name exists
144	>	and without raising and exception if it does not.
145	>
146	>	9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
147	>	consistency with SQL queries.
148	>
149	>	10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
150	>	When true, SQL statement parameter names are parsed case sensitive. Note for
151	>	TIBDataSet only applies to Select query.
152	>
153	>	11. IBEvents: removing a TIBEvent component from a form should no longer result in
154	>	an IDE exception.
155	>
156	>	12. LocalDBSupport: initial database creation should now work correctly
157	>	when the schema source is an sql file.
158	>
159	>	13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
160	>	when defined, this handler will be called by the internal TIBXScript during
161	>	initial database creation when the schema source is an sql file and may be used
162	>	to provide a visual indication of progress in console mode.
163	>
164	>	14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
165	>	to true while a new local database is being created and its schema populated.
166	>	Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
167	>	when the database is disconnected/connected during the create DB procedure.
168	>
169	>	15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
170	>	are now always ignored and replaced by the user name and password provided as
171	>	the login parameters for the TIBDatabase referenced from the TIBXScript. The
172	>	IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
173	>	completely ignored if this property is true.
174	>
175	>	16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
176	>	to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
177	>	ImageIndex and SelectImageIndex values on AddNode.
178	>
179	>	17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
180	>	read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
181	>	the same database connection.
182	>
183	>	18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
184	>	if provided, this should be an conditional SQL expression suitable for
185	>	including in an SQL Select statement "where" clause. If non-empty and the
186	>	"Filtered" property is true then the SQL expression provided as the value of
187	>	the "Filter" property is "ANDed" with any existing condition statement
188	>	in the SQL statement's "Where" clause.
189	>
190	>	If the "Filter" property is set at run time, the "Filtered" property is true
191	>	and the dataset is already open, then the dataset is closed and re-opened automatically.
192	>
193	>	The "Filter" condition may include IBX style parameters. In which case, their
194	>	value must be set by the dataset's "OnBeforeOpen" event handler.
195	>
196	>	This is a public property for TIBDataSet and TIBQuery query and intended for
197	>	use at run time.
198	>
199	>	Note: The property is a published property of TIBTable. The TIBTable functionality
200	>	is unaffected by this change.
