49	>	1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
50	>
51	>	2. Remove constraint in IAttachment.HasScollableCursors that returned false when
52	>	using remote protocol. Scrollable cursors with remote database expected to
53	>	be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
54	>	a not supported error.
55	>
56	>	3. IStatement: new function;
57	>	TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
58	>	TStatementFlags = set of TStatementFlag;
59	>	function GetFlags: TStatementFlags;
60	>
61	>	4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
62	>	compatibility.
63	>	In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
64	>	type changes from ExecProcedure to Select. So that ExecuteQuery can continue
65	>	to be used with Update...Retruning statements that return a singleton row,
66	>	instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
67	>	it will open the cursor and return the first row only.
68	>
69	>	5. ITransaction: new functions:
70	>	function GetIsReadOnly: boolean;
71	>	function GetTransactionID: integer;
72	>	function GetTrInformation(Requests: array of byte): ITrInformation; overload;
73	>	function GetTrInformation(Request: byte): ITrInformation; overload;
74	>
75	>	The latter two return the Transaction Information block. The first two extract
76	>	information the Transaction Information block
77	>
78	>	6. New function TSQLTokeniser.ReadCharacters
79	>	Used internally.
80	>
81	>	7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
82	>	parameter placeholders instead of named parameters.
83	>
84	>	8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
85	>	transaction handle is now ignored if Rollback/Commit is called with Force=true

96		user to disable them on a per statement basis. Note this can risk out-of-date
97		statement BLR. See User Guide.

99	+	3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
100	+	stored procedure and hence avoids replacing named parameters within a containing
101	+	BEGIN..END block.
102	+
103	+	4. ISQLParam: using a string value to set an integer field with a scale factor of
104	+	zero is now treated as a special case to avoid the risk of floating point
105	+	rounding errors affecting pure integers.
106	+
107	+	5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
108	+
109	+	6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
110	+	SQL Parameter metadata (methods moved from ISQLParam).
111	+
112	+	7. ISQLParam: new method
113	+	function getColMetadata: IParamMetaData;
114	+	This instance of IParamMetaData returns the original column metadata which is unmutable.
115	+	Note: ISQLParam metadata can change after a parameter value has been set e.g when
116	+	setting a VARCHAR column to an integer value.
117	+
118	+	8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
119	+	procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
120	+	also IAttachment:
121	+	function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
122	+	function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
123	+	function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
124	+	aSQLDialect: integer; GenerateParamNames: boolean=false;
125	+	CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
126	+	function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
127	+	GenerateParamNames: boolean=false;
128	+	CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
129	+
130	+	9. Support for scrollable cursors added. New/updated methods:
131	+	IAttachment:
132	+	function HasScollableCursors: boolean;
133	+	function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
134	+	Scrollable: boolean=false): IResultSet; overload;
135	+	function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
136	+	function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
137	+	params: array of const): IResultSet; overload;
138	+	function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
139	+	params: array of const): IResultSet; overload;
140	+	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
141	+	params: array of const): IResultSet; overload;
142	+	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
143	+	Scrollable: boolean=false): IResultSet; overload;
144	+	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
145	+	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
146	+	params: array of const): IResultSet; overload;
147	+	function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
148	+	function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
149	+	params: array of const): IResultSet; overload;
150	+	IStatement:
151	+	function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
152	+	IResultSet:
153	+	function FetchPrior: boolean; {fetch previous record}
154	+	function FetchFirst:boolean; {fetch first record}
155	+	function FetchLast: boolean; {fetch last record}
156	+	function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
157	+	function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
158	+	function IsBof: boolean;
159	+
160	+	10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
161	+
162	+	11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
163	+	may be noticeable when a line separator occurs inside quoted text. The quoted text
164	+	output by the tokeniser will now use the platform specific lineEnding regardless
165	+	of whether the input uses the CRLF or LF as a line separator.
166	+
167	+	12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
168	+
169	+
