3	>	1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
4	>
5	>	2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
6	>	will now be encoded inline (i.e. as part of the parameter buffer) if they are
7	>	shorter than a pre-set limit. Longer values continue to be saved as blobs as a
8	>	separate server interaction. This is intended as a performance optimisation.
9	>
10	>	The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
11	>	IAttachment interface functions:
12	>
13	>	function GetInlineBlobLimit: integer;
14	>	procedure SetInlineBlobLimit(limit: integer);
15	>
16	>	3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
17	>	user as the functionality is embedded in the implementation of the IStatement
18	>	interface. Three new functions are defined:
19	>
20	>	procedure AddToBatch;
21	>	function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
22	>	procedure CancelBatch;
23	>	function GetBatchCompletion: IBatchCompletion;
24	>	function GetBatchRowLimit: integer;
25	>	procedure SetBatchRowLimit(aLimit: integer);
26	>
27	>	Also
28	>
29	>	function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
30	>	function HasBatchMode: boolean;         {true if and only if IBatch Supported}
31	>
32	>	For more information see the User Guide.
33	>
34	>	4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
35	>	provided with the EIBInterBaseError now include all three parts.
36	>
37	>	5. Firebird.pas and include files updated to Firebird 4.0.0
38	>
39	>	6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
40	>	Returns SQL Statement type as a text string;
41	>
42	>	7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
43	>	an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
44	>
45	>	FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
46	>
47	>	1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
48	>	typo in FB30Statement.pas that caused an unknown parameter error.
49	>
50	>	FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
51	>
52	>	1. Imported (Firebird) constants updated for Firebird 4.
53	>
54	>	2. Firebird.pas from Firebird 4 integrated into source code tree.
55	>
56	>	3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
57	>
58	>	4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
59	>
60	>	5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
61	>	QueryInterface may be used to coerce this interface from IFirebirdAPI. The
62	>	interface provides a single method "function GetIMasterIntf: IMaster". This provides
63	>	type safe access to the Firebird IMaster interface and avoids the need to turn
64	>	off object checks when coercing "function GetIMaster: TObject" to IMaster.
65	>
66	>	6. New IFirebirdAPI Calls:
67	>	function HasLocalTZDB: boolean;
68	>	function HasTimeZoneSupport: boolean;
69	>	function HasExtendedTZSupport: boolean;
70	>	procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
71	>	function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
72	>
73	>	7. New IAttachment Calls:
74	>	function HasDecFloatSupport: boolean;
75	>	function GetTimeZoneServices: ITimeZoneServices;
76	>	function HasTimeZoneSupport: boolean;
77	>
78	>	8. New Interface ITimeZoneServices.
79	>
80	>	9. New ISQLData API Calls:
81	>	procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
82	>	procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
83	>	procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
84	>	procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
85	>	function GetAsUTCDateTime: TDateTime;
86	>	function GetAsBCD: tBCD;
87	>
88	>	10. New ISQLParam API Calls
89	>	procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
90	>	procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
91	>	procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

96	>	function GetTransaction: ITransaction;
97	>	procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;

101	>	procedure SetAsUTCDateTime(aUTCTime: TDateTime);
102	>	procedure SetAsBcd(aValue: tBCD);
103	>
104	>	11. New IArray API Calls
105	>	procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
106	>	procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

135	>	FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
136	>
137	>	1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
138	>	with a Firebrid 3 client library.
139	>
140	>	2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
141	>	If a client library path is not explicitly provided and the FIREBIRD environment
142	>	variable is set then the directory given by this variable and any 'lib' subdirectory
143	>	are searched for the Firebird client library. Only if none is found, is the default
144	>	client library used.
145	>
146	>	3.  IUtil.FormatStatus now used to format error messages when using new API
147	>
148	>	4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
149	>
150	>	5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
151	>	returned using GetAsString and the string codepage is UTF8, the string is truncated so
152	>	that the byte length corresponds to the number of characters specified for the column.
153	>	SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
154	>	correct behaviour but may affect some implementations that relied upon automatic
155	>	trimming of trailing white space.
156	>
157	>	6.  New IFirebirdAPI Calls:
158	>	function GetClientMajor: integer;
159	>	function GetClientMinor: integer;
160	>
161	>	7.  IColumnMetaData and IArrayMetaData: new method
162	>	function GetCharSetWidth: integer;
163	>
164	>	FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
