+FBINTF Change Log  version            (1.1-2) Mon, 09 Apr 2018 11:30:46 +0100
->
+FBINTF Change Log  version          (1.4-1 Build 14083) Fri, 20 Oct 2023 11:41:24 +0100
->
->
+. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
->
+   checks for range checking.
->
->
+. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that
->
+   any additional error information is decoded.
->
->
+. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING
->
+   charsetid is now preserved and size is set to default blob size. Now aligns with
->
+   FB3 and later.
->
->
+. DDL and DML string literals are now explicitly set to the connection character
->
+   set rather than the default character set provided by the compiler.
->
->
+. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing
->
+   now makes use of the RTL fpwidestring unit for support of international character
->
+   sets.
->
->
+. Database exception handling (see section 9.3 in user guide).
->
+    * For FB3 and later API: Connection Character set now applied to message returned
->
+      by fb_interpret and message then transliterated if necessary to the system character set.
->
+    * For Legacy API: The message character set is guessed as UTF8 unless invalid
->
+      UTF8 characters found when connection character set is assumed. Message then
->
+      transliterated if necessary to system character set.
->
+      Note: this difference of behaviour is because legacy API presents exception messages
->
+      "as is", while FB3 server attempts to transliterate to connection character set.
->
->
+FBINTF Change Log  version          (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
->
->
+. Support package fbudr added for support of User Defined Routines (UDRs), and package
->
+   fbudrtestbed for client side debugging of UDR libraries.
->
->
+. Package layout changed with introduction of udr support. IB*.pas files moved from
->
+    root directory to "client". IBHeader moved to "Client".
->
->
+. Delphi packages: all packages now compile .dcp and .bpi files to either
->
+   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
->
+   fbintf.dcp and fbintf.bpi files from other locations.
->
->
+. Client side journaling support added. Interface changes
->
+   IAttachment
->
+    function JournalingActive: boolean;
->
+    function GetJournalOptions: TJournalOptions;
->
+    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
->
+    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
->
+    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
->
+    procedure StopJournaling(RetainJournal: boolean);
->
->
+. Transactions may now be given a local transaction name:
->
+   IFirebirdAPI
->
+     function StartTransaction(Attachments: array of IAttachment;
->
+             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
->
+             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
->
+             aName: AnsiString=''): ITransaction; overload;
->
+     function StartTransaction(Attachments: array of IAttachment;
->
+             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
->
+             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
->
+             aName: AnsiString=''): ITransaction; overload;
->
->
+   IAttachment
->
+    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
->
+    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
->
+    function StartTransaction(TPB: array of byte;
->
+                              DefaultCompletion: TTransactionCompletion=taCommit;
->
+                              aName: AnsiString=''): ITransaction; overload;
->
+    function StartTransaction(TPB: ITPB;
->
+                              DefaultCompletion: TTransactionCompletion=taCommit;
->
+                              aName: AnsiString=''): ITransaction; overload;
->
->
+  ITransaction
->
+    function GetTransactionName: AnsiString;
->
+    procedure SetTransactionName(aValue: AnsiString);
->
->
+. Additional Transaction information
->
+     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
->
->
+   ITransaction
->
+     function GetDefaultCompletion: TTransactionCompletion;
->
+     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
->
->
+. New IAttachment helper functions
->
+     function HasTable(aTableName: AnsiString): boolean;
->
+     function HasFunction(aFunctionName: AnsiString): boolean;
->
+     function HasProcedure(aProcName: AnsiString): boolean;
->
+     function GetAttachmentID: integer;
->
+     function GetCharSetID: integer;
->
->
+. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
->
+   will be allocated for batch operations.
->
->
+. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
->
+    function GetStatement: IStatement;
->
+    function GetTransaction: ITransaction;
->
+    function GetAttachment: IAttachment;
->
->
+. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
->
+    interfaces.
->
->
+. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
->
+    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
->
+    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
->
+    of numerics without loss of precision.
->
->
+. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
->
->
+. ISQLParams new method "Clear"
->
->
+. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
->
+    request rather than on attachment connect.
->
->
+. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
->
+    fact that SQLCodes are soon to be deprecated. In the future, the other options
->
+    will be silently ignored if SQLCode support is not present in the Firebird
->
+    Client library.
->
->
+. ITransaction changes Rollback and Commit from procedures to functions:
->
+      function Commit(Force: boolean=false): TTrCompletionState;
->
+      function Rollback(Force: boolean=false): TTrCompletionState;
->
->
+    Specifically, this is to allow the functions to report back a failed commit or
->
+    rollback when Force = true. In the case, the transaction handle has been
->
+    released, while the transaction remains in limbo.
->
->
+. IAttachment ExecImmediate.
->
+    When the transaction parameters are provided as an array of const and the
->
+    statement fails, the transaction is rolledback (forced) before the exception
->
+    is raised.
->
->
+. In Firebird 3 and later API: the status vector is now a thread var, as was
->
+    already the case with the legacy API. Avoids problems when calling underlying
->
+    Firebird API in multiple threads.
->
->
+. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
->
+    reasons.
->
->
+. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
->
->
+. TSQLXMLReader: handle 'blob' as a reserved word
->
->
+. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
->
->
->
+FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
->
->
+. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
->
->
+. Remove constraint in IAttachment.HasScollableCursors that returned false when
->
+   using remote protocol. Scrollable cursors with remote database expected to
->
+   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
->
+   a not supported error.
->
->
+. IStatement: new function;
->
+    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
->
+    TStatementFlags = set of TStatementFlag;
->
+    function GetFlags: TStatementFlags;
->
->
+. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
->
+   compatibility.
->
+   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
->
+   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
->
+   to be used with Update...Retruning statements that return a singleton row,
->
+   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
->
+   it will open the cursor and return the first row only.
->
->
+. ITransaction: new functions:
->
+    function GetIsReadOnly: boolean;
->
+    function GetTransactionID: integer;
->
+    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
->
+    function GetTrInformation(Request: byte): ITrInformation; overload;
->
->
+   The latter two return the Transaction Information block. The first two extract
->
+   information the Transaction Information block
->
->
+. New function TSQLTokeniser.ReadCharacters
->
+   Used internally.
->
->
+. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
->
+   parameter placeholders instead of named parameters.
->
->
+. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
->
+   transaction handle is now ignored if Rollback/Commit is called with Force=true
->
->
+. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
->
+   used to get an IBError Message instead of isc_interprete.
->
->
+. Internal tidyup. Native code now used for decoding integers and the events
->
+    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
->
+    isc_event_block and isc_event_counts.
->
->
+. New IAttachment function
->
+     function GetAttachmentID: integer;
->
->
+. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
->
+    subclasses to enable UDR support.
->
->
+FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
->
->
+. TFBClientAPI.GetProcAddr. Add check for nil reference.
->
->
+. IStatement: new methods:
->
+    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
->
+    function GetStaleReferenceChecks: boolean;
->
->
+   In previous versions, stale reference checks were always enabled. This allows the
->
+   user to disable them on a per statement basis. Note this can risk out-of-date
->
+   statement BLR. See User Guide.
->
->
+. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
->
+   stored procedure and hence avoids replacing named parameters within a containing
->
+   BEGIN..END block.
->
->
+. ISQLParam: using a string value to set an integer field with a scale factor of
->
+   zero is now treated as a special case to avoid the risk of floating point
->
+   rounding errors affecting pure integers.
->
->
+. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
->
->
+. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
->
+   SQL Parameter metadata (methods moved from ISQLParam).
->
->
+. ISQLParam: new method
->
+     function getColMetadata: IParamMetaData;
->
+   This instance of IParamMetaData returns the original column metadata which is unmutable.
->
+   Note: ISQLParam metadata can change after a parameter value has been set e.g when
->
+   setting a VARCHAR column to an integer value.
->
->
+. IStatement: can now set cursor name when opening a cursor. New overloaded method:
->
+    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
->
+   also IAttachment:
->
+    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
->
+    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
->
+    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
->
+                       aSQLDialect: integer; GenerateParamNames: boolean=false;
->
+                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
->
+    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
->
+                       GenerateParamNames: boolean=false;
->
+                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
->
->
+. Support for scrollable cursors added. New/updated methods:
->
+   IAttachment:
->
+    function HasScollableCursors: boolean;
->
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
->
+                             Scrollable: boolean=false): IResultSet; overload;
->
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
->
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
->
+                             params: array of const): IResultSet; overload;
->
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
->
+                             params: array of const): IResultSet; overload;
->
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
->
+                             params: array of const): IResultSet; overload;
->
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
->
+                             Scrollable: boolean=false): IResultSet; overload;
->
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
->
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
->
+                             params: array of const): IResultSet; overload;
->
+    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
->
+    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
->
+                             params: array of const): IResultSet; overload;
->
+   IStatement:
->
+     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
->
+   IResultSet:
->
+    function FetchPrior: boolean; {fetch previous record}
->
+    function FetchFirst:boolean; {fetch first record}
->
+    function FetchLast: boolean; {fetch last record}
->
+    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
->
+    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
->
+    function IsBof: boolean;
->
->
+. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
->
->
+. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
->
+    may be noticeable when a line separator occurs inside quoted text. The quoted text
->
+    output by the tokeniser will now use the platform specific lineEnding regardless
->
+    of whether the input uses the CRLF or LF as a line separator.
->
->
+. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
->
->
->
+FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
->
->
+. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
->
->
+. Support for inline blob encoding. Blob values pass using the "SetAsString" method
->
+   will now be encoded inline (i.e. as part of the parameter buffer) if they are
->
+   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
->
+   separate server interaction. This is intended as a performance optimisation.
->
->
+   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
->
+   IAttachment interface functions:
->
->
+    function GetInlineBlobLimit: integer;
->
+    procedure SetInlineBlobLimit(limit: integer);
->
->
+. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
->
+   user as the functionality is embedded in the implementation of the IStatement
->
+   interface. Three new functions are defined:
->
->
+    procedure AddToBatch;
->
+    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
->
+    procedure CancelBatch;
->
+    function GetBatchCompletion: IBatchCompletion;
->
+    function GetBatchRowLimit: integer;
->
+    procedure SetBatchRowLimit(aLimit: integer);
->
->
+   Also
->
->
+    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
->
+    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
->
->
+   For more information see the User Guide.
->
->
+. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
->
+   provided with the EIBInterBaseError now include all three parts.
->
->
+. Firebird.pas and include files updated to Firebird 4.0.0
->
->
+. New IStatement method: function GetSQLStatementTypeName: AnsiString;
->
+   Returns SQL Statement type as a text string;
->
->
+. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
->
+   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
->
->
+FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
->
->
+. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
->
+   typo in FB30Statement.pas that caused an unknown parameter error.
->
->
+FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
->
->
+. Imported (Firebird) constants updated for Firebird 4.
->
->
+. Firebird.pas from Firebird 4 integrated into source code tree.
->
->
+. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
->
->
+. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
->
->
+. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
->
+   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
->
+   interface provides a single method "function GetIMasterIntf: IMaster". This provides
->
+   type safe access to the Firebird IMaster interface and avoids the need to turn
->
+   off object checks when coercing "function GetIMaster: TObject" to IMaster.
->
->
+. New IFirebirdAPI Calls:
->
+    function HasLocalTZDB: boolean;
->
+    function HasTimeZoneSupport: boolean;
->
+    function HasExtendedTZSupport: boolean;
->
+    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
->

+. New IAttachment Calls:
->
+    function HasDecFloatSupport: boolean;
->
+    function GetTimeZoneServices: ITimeZoneServices;
->
+    function HasTimeZoneSupport: boolean;
->
->
+. New Interface ITimeZoneServices.

->

->
->
+. IDPB, ITPB and ISPB: new interface method
->
+      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
->
+    This is used to add a parameter block item by the string equivalent of its
->
+    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
->
->
+. IDPBItem/ITPBItem/ISPBItem: new interface method:
->
+      function getParamTypeName: AnsiString;
->
->
+. fb_shutdown now called before unloading Firebird library. This can avoid a
->
+     SIGEVENT error when a programme using the embeded server is unloaded.
->
->
+FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
->
->
+. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
->
+   with a Firebrid 3 client library.
->
->
+. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
->
+    If a client library path is not explicitly provided and the FIREBIRD environment
->
+    variable is set then the directory given by this variable and any 'lib' subdirectory
->
+    are searched for the Firebird client library. Only if none is found, is the default
->
+    client library used.
->
->
+.  IUtil.FormatStatus now used to format error messages when using new API
->
->
+.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
->
->
+.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
->
+    returned using GetAsString and the string codepage is UTF8, the string is truncated so
->
+    that the byte length corresponds to the number of characters specified for the column.
->
+    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
->
+    correct behaviour but may affect some implementations that relied upon automatic
->
+    trimming of trailing white space.
->
->
+.  New IFirebirdAPI Calls:
->
+      function GetClientMajor: integer;
->
+      function GetClientMinor: integer;
->
->
+.  IColumnMetaData and IArrayMetaData: new method
->
+      function GetCharSetWidth: integer;

->
->
+. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
->
+   case sensitive
->
->
+. Single line SQL comments starting with '--' are now recognised by SQL Parser.
->
->
+. New API Calls:
->
+        IColumnMetaData.GetStatement
->
+        IColumnMetaData.GetTransaction
->
+        ISQLData.GetStrDataLength
->
+        IResults.GetStatement
->
+        IAttachment.OpenBlob (using Blob metadata)
->
+        IAttachment.OpenArray (using array metadata)
->
->
+. FBMessages: removal of unused messages
->
->
+. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
->
->
+. TIBSQLStatementType: SQLSavePoint added to end of enumeration.

+FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
->
->
+. Fix a problem with the SQL parameter parser that failed to recognise parameters
->
+   where the second character of the parameter name is a numeric.
->
->
+. New method for IAttachment: procedure getFBVersion(version: TStrings);
->
+   This returns the isc_version connection information as one or more lines.
->
+   This is the same information as returned by isql with the -z option.
->
->
+. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
->
+   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
->
+   compiler option then the Firebird 3 API is no longer compiled in.
->
->
+. IColumnMetaData: new method.
->
->
+   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
->
+                        dfDateTime,   {SQL DATETIME}
->
+                        dfTime);
->
->
+   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
->
->
+   This returns the max. number of characters returned by the "AsString" method
->
+   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
->
->
+. Additional argument for IAttachment.PrepareWithNamedParameters -
->
+     CaseSensitiveParams: boolean = false
->
->
+   If this argument is set to true then SQL parameter names are assumed to be case
->
+   sensitive and must be referenced (using ISQLParams.ByName) using the case
->
+   sensitive name.
->
->
+. Bug fix: when setting a query parameter, it is now possible, when the parameter
->
+   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
->
+   .AsCurrency) and then subsequently to update the value to a non-numeric string
->
+   using .AsString.

+FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
->
->
+. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
->
->
+. Restrict IsMultiThread check to Unix only for compatibility with
->
+   https://bugs.freepascal.org/view.php?id=30535
->
->
+. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
->
+   named parameters and is intended to avoid problems with (e.g.) Execute Block
->
+   and processing internal parameters as statement parameters.
->
->
+. New interface IFirebirdLibrary provides access to the underlying firebird DLL
->
+   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
->
->
+. New function added to IB.pas
->
->
+   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
->
->
+   This allows a Firebird Library to be loaded from an explicit path. use the
->
+   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
->
+   the library. It is possible to load Firebird libraries from different locations
->
+   simultaneously, each with a distinct IFirebirdAPI.
->
->
+FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
+. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
+   program compiled with -CR command line switch.
+. Testsuite Test10 updated to include thread synchronisation for event reporting.
-+
+. URL Connection Strings: inet4 and inet6 now recognised.
-+
-+
+. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
-+
-+
+. IAttachment.CharSetName2CharSetID is now performed case insensitive.
