2 >
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 Note this can risk out-of-date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.

14 >
15 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
16 >
17 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
18 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
19 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
20 >   separate server interaction. This is intended as a performance optimisation.
21 >
22 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
23 >   IAttachment interface functions:
24 >
25 >    function GetInlineBlobLimit: integer;
26 >    procedure SetInlineBlobLimit(limit: integer);
27 >
28 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
29 >   user as the functionality is embedded in the implementation of the IStatement
30 >   interface. Three new functions are defined:
31 >
32 >    procedure AddToBatch;
33 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
34 >    procedure CancelBatch;
35 >    function GetBatchCompletion: IBatchCompletion;
36 >    function GetBatchRowLimit: integer;
37 >    procedure SetBatchRowLimit(aLimit: integer);
38 >
39 >   Also
40 >
41 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
42 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
43 >
44 >   For more information see the User Guide.
45 >
46 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
47 >   provided with the EIBInterBaseError now include all three parts.
48 >
49 > 5. Firebird.pas and include files updated to Firebird 4.0.0
50 >
51 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
52 >   Returns SQL Statement type as a text string;
53 >
54 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
55 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
56 >
57 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
58 >
59 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
60 >   typo in FB30Statement.pas that caused an unknown parameter error.
61 >
62 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
63 >
64 > 1. Imported (Firebird) constants updated for Firebird 4.
65 >
66 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
67 >
68 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
69 >
70 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
71 >
72 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
73 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
74 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
75 >   type safe access to the Firebird IMaster interface and avoids the need to turn
76 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
77 >
78 > 6. New IFirebirdAPI Calls:
79 >    function HasLocalTZDB: boolean;
80 >    function HasTimeZoneSupport: boolean;
81 >    function HasExtendedTZSupport: boolean;
82 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
83 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
84 >
85 > 7. New IAttachment Calls:
86 >    function HasDecFloatSupport: boolean;
87 >    function GetTimeZoneServices: ITimeZoneServices;
88 >    function HasTimeZoneSupport: boolean;
89 >
90 > 8. New Interface ITimeZoneServices.
91 >
92 > 9. New ISQLData API Calls:
93 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
94 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
95 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
96 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
97 >    function GetAsUTCDateTime: TDateTime;
98 >    function GetAsBCD: tBCD;
99 >
100 > 10. New ISQLParam API Calls
101 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
102 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
103 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

106 >    function GetAsBCD: tBCD;
107 >    function GetStatement: IStatement;
108 >    function GetTransaction: ITransaction;
109 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
110 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
111 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
112 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
113 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
114 >    procedure SetAsBcd(aValue: tBCD);
115 >
116 > 11. New IArray API Calls
117 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
118 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

142 >      function getParamTypeName: AnsiString;
143 >
144 > 15. fb_shutdown now called before unloading Firebird library. This can avoid a

146 >
147 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
148 >
149 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
150 >   with a Firebrid 3 client library.
151 >
152 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
153 >    If a client library path is not explicitly provided and the FIREBIRD environment
154 >    variable is set then the directory given by this variable and any 'lib' subdirectory
155 >    are searched for the Firebird client library. Only if none is found, is the default
156 >    client library used.
157 >
158 > 3.  IUtil.FormatStatus now used to format error messages when using new API
159 >
160 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
161 >
162 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
163 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
164 >    that the byte length corresponds to the number of characters specified for the column.
165 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
166 >    correct behaviour but may affect some implementations that relied upon automatic
167 >    trimming of trailing white space.
168 >
169 > 6.  New IFirebirdAPI Calls:
170 >      function GetClientMajor: integer;
171 >      function GetClientMinor: integer;
172 >
173 > 7.  IColumnMetaData and IArrayMetaData: new method
174 >      function GetCharSetWidth: integer;
175 >
176 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
