57 >    function GetAttachment: IAttachment;
58 >
59 > 7. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
60 >   interfaces.
61 >
62 > 8. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
63 >   and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
64 >   functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
65 >   of numerics without loss of precision.
66 >
67 > 9. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.

72 >
73 > 12. Package layout changed with introduction of udr support. IB*.pas files moved from
74 >    root directory to "client". IBHeader move to "Client".
75 >
76 > 13. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
77 >    request rather than on attachment connect.
78 >
79 >
80 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
81 >
82 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
83 >
84 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
85 >   using remote protocol. Scrollable cursors with remote database expected to
86 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
87 >   a not supported error.
88 >
89 > 3. IStatement: new function;
90 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
91 >    TStatementFlags = set of TStatementFlag;
92 >    function GetFlags: TStatementFlags;
93 >
94 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
95 >   compatibility.
96 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
97 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
98 >   to be used with Update...Retruning statements that return a singleton row,
99 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
100 >   it will open the cursor and return the first row only.
101 >
102 > 5. ITransaction: new functions:
103 >    function GetIsReadOnly: boolean;
104 >    function GetTransactionID: integer;
105 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
106 >    function GetTrInformation(Request: byte): ITrInformation; overload;
107 >
108 >   The latter two return the Transaction Information block. The first two extract
109 >   information the Transaction Information block
110 >
111 > 6. New function TSQLTokeniser.ReadCharacters
112 >   Used internally.
113 >
114 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
115 >   parameter placeholders instead of named parameters.
116 >
117 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
118 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
119 >
120 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
121 >   used to get an IBError Message instead of isc_interprete.
122 >
123 > 10. Internal tidyup. Native code now used for decoding integers and the events
124 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
125 >    isc_event_block and isc_event_counts.
126 >
127 > 11. New IAttachment function
128 >     function GetAttachmentID: integer;
129 >
130 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
131 >    subclasses to enable UDR support.
132 >
133 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
134 >
135 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
136 >
137 > 2. IStatement: new methods:
138 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
139 >    function GetStaleReferenceChecks: boolean;
140 >
141 >   In previous versions, stale reference checks were always enabled. This allows the
142 >   user to disable them on a per statement basis. Note this can risk out-of-date
143 >   statement BLR. See User Guide.
144 >
145 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
146 >   stored procedure and hence avoids replacing named parameters within a containing
147 >   BEGIN..END block.
148 >
149 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
150 >   zero is now treated as a special case to avoid the risk of floating point
151 >   rounding errors affecting pure integers.
152 >
153 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
154 >
155 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
156 >   SQL Parameter metadata (methods moved from ISQLParam).
157 >
158 > 7. ISQLParam: new method
159 >     function getColMetadata: IParamMetaData;
160 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
161 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
162 >   setting a VARCHAR column to an integer value.
163 >
164 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
165 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
166 >   also IAttachment:
167 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
168 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
169 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
170 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
171 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
172 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
173 >                       GenerateParamNames: boolean=false;
174 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
175 >
176 > 9. Support for scrollable cursors added. New/updated methods:
177 >   IAttachment:
178 >    function HasScollableCursors: boolean;
179 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
180 >                             Scrollable: boolean=false): IResultSet; overload;
181 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
182 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
183 >                             params: array of const): IResultSet; overload;
184 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
185 >                             params: array of const): IResultSet; overload;
186 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
187 >                             params: array of const): IResultSet; overload;
188 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
189 >                             Scrollable: boolean=false): IResultSet; overload;
190 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
191 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
192 >                             params: array of const): IResultSet; overload;
193 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
194 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
195 >                             params: array of const): IResultSet; overload;
196 >   IStatement:
197 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
198 >   IResultSet:
199 >    function FetchPrior: boolean; {fetch previous record}
200 >    function FetchFirst:boolean; {fetch first record}
201 >    function FetchLast: boolean; {fetch last record}
202 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
203 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
204 >    function IsBof: boolean;
205 >
206 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
207 >
208 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
209 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
210 >    output by the tokeniser will now use the platform specific lineEnding regardless
211 >    of whether the input uses the CRLF or LF as a line separator.
212 >
213 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
214 >
215 >
216 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
217 >
218 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
219 >
220 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
221 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
222 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
223 >   separate server interaction. This is intended as a performance optimisation.
224 >
225 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
226 >   IAttachment interface functions:
227 >
228 >    function GetInlineBlobLimit: integer;
229 >    procedure SetInlineBlobLimit(limit: integer);
230 >
231 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
232 >   user as the functionality is embedded in the implementation of the IStatement
233 >   interface. Three new functions are defined:
234 >
235 >    procedure AddToBatch;
236 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
237 >    procedure CancelBatch;
238 >    function GetBatchCompletion: IBatchCompletion;
239 >    function GetBatchRowLimit: integer;
240 >    procedure SetBatchRowLimit(aLimit: integer);
241 >
242 >   Also
243 >
244 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
245 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
246 >
247 >   For more information see the User Guide.
248 >
249 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
250 >   provided with the EIBInterBaseError now include all three parts.
251 >
252 > 5. Firebird.pas and include files updated to Firebird 4.0.0
253 >
254 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
255 >   Returns SQL Statement type as a text string;
256 >
257 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
258 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
259 >
260 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
261  
262   1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
263     typo in FB30Statement.pas that caused an unknown parameter error.
