Last official TRegExpr - deprecated methods

To include last TRegExpr from its official repo https://github.com/andgineer/TRegExpr which is now maintained by me (de facto), I need to support old 'symbols', ie methods and properties, right? I found these deleted 'symbols':

    function ExecNext: boolean; overload;

    function ExecPos(AOffset: integer; ATryOnce: boolean): boolean; overload;

    class function InvertCaseFunction(const Ch: REChar): REChar;

    property UseUnicodeWordDetection: boolean read FUseUnicodeWordDetection write FUseUnicodeWordDetection;

    property LinePairedSeparator: RegExprString read GetLinePairedSeparator write SetLinePairedSeparator; // ###0.941

    property InvertCase: TRegExprInvertCaseFunction read fInvertCase write fInvertCase; // ##0.935

    property UseOsLineEndOnReplace: boolean read FUseOsLineEndOnReplace write SetUseOsLineEndOnReplace;

    Property EmptyInputRaisesError : Boolean Read FEmptyInputRaisesError Write FEmptyInputRaisesError;

Do I need to include them to official TRegExpr as DEPRECATED, so FPC guys will accept my version?
