3	>	1. TFBClientAPI.GetProcAddr. Add check for nil reference.
4	>
5	>	2. IStatement: new methods:
6	>	procedure SetStaleReferenceChecks(Enable:boolean); {default true}
7	>	function GetStaleReferenceChecks: boolean;
8	>
9	>	In previous versions, stale reference checks were always enabled. This allows the
10	>	user to disable them on a per statement basis. Note this can risk out-of-date
11	>	statement BLR. See User Guide.
12	>
13	>	3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
14	>	stored procedure and hence avoids replacing named parameters within a containing
15	>	BEGIN..END block.
16	>
17	>	4. ISQLParam: using a string value to set an integer field with a scale factor of
18	>	zero is now treated as a special case to avoid the risk of floating point
19	>	rounding errors affecting pure integers.
20	>
21	>	5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
22	>
23	>	6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24	>	SQL Parameter metadata (methods moved from ISQLParam).
25	>
26	>	7. ISQLParam: new method
27	>	function getColMetadata: IParamMetaData;
28	>	This instance of IParamMetaData returns the original column metadata which is unmutable.
29	>	Note: ISQLParam metadata can change after a parameter value has been set e.g when
30	>	setting a VARCHAR column to an integer value.
31	>
32	>	8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33	>	procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34	>	also IAttachment:
35	>	function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36	>	function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37	>	function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38	>	aSQLDialect: integer; GenerateParamNames: boolean=false;
39	>	CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40	>	function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41	>	GenerateParamNames: boolean=false;
42	>	CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43	>
44	>	9. Support for scrollable cursors added. New/updated methods:
45	>	IAttachment:
46	>	function HasScollableCursors: boolean;
47	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
48	>	Scrollable: boolean=false): IResultSet; overload;
49	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
50	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
51	>	params: array of const): IResultSet; overload;
52	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
53	>	params: array of const): IResultSet; overload;
54	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
55	>	params: array of const): IResultSet; overload;
56	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
57	>	Scrollable: boolean=false): IResultSet; overload;
58	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
59	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
60	>	params: array of const): IResultSet; overload;
61	>	function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
62	>	function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
63	>	params: array of const): IResultSet; overload;
64	>	IStatement:
65	>	function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
66	>	IResultSet:
67	>	function FetchPrior: boolean; {fetch previous record}
68	>	function FetchFirst:boolean; {fetch first record}
69	>	function FetchLast: boolean; {fetch last record}
70	>	function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
71	>	function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
72	>	function IsBof: boolean;
73	>
74	>	10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
75	>
76	>	11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
77	>	may be noticeable when a line separator occurs inside quoted text. The quoted text
78	>	output by the tokeniser will now use the platform specific lineEnding regardless
79	>	of whether the input uses the CRLF or LF as a line separator.
80	>
81	>	12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
82	>
83	>
84	>	FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
85	>
86	>	1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
87	>
88	>	2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
89	>	will now be encoded inline (i.e. as part of the parameter buffer) if they are
90	>	shorter than a pre-set limit. Longer values continue to be saved as blobs as a
91	>	separate server interaction. This is intended as a performance optimisation.
92	>
93	>	The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
94	>	IAttachment interface functions:
95	>
96	>	function GetInlineBlobLimit: integer;
97	>	procedure SetInlineBlobLimit(limit: integer);
98	>
99	>	3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
100	>	user as the functionality is embedded in the implementation of the IStatement
101	>	interface. Three new functions are defined:
102	>
103	>	procedure AddToBatch;
104	>	function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
105	>	procedure CancelBatch;
106	>	function GetBatchCompletion: IBatchCompletion;
107	>	function GetBatchRowLimit: integer;
108	>	procedure SetBatchRowLimit(aLimit: integer);
109	>
110	>	Also
111	>
112	>	function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
113	>	function HasBatchMode: boolean;         {true if and only if IBatch Supported}
114	>
115	>	For more information see the User Guide.
116	>
117	>	4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
118	>	provided with the EIBInterBaseError now include all three parts.
119	>
120	>	5. Firebird.pas and include files updated to Firebird 4.0.0
121	>
122	>	6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
123	>	Returns SQL Statement type as a text string;
124	>
125	>	7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
126	>	an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
127	>
128	>	FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100

130		1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
131		typo in FB30Statement.pas that caused an unknown parameter error.
