      * IO::Compress::Zip

        - Added Zip64 documentation.

        - Fixed extended timestamp.
          Creation time isn't available in Unix so only store the
          modification time and the last access time in the extended field.

        - Fixed file mode.

        - Added ExtAttr option to control the value of the "external file
          attributes" field in the central directory.

        - Added Unix2 extended attribute ("Ux").
          This stores the UID & GID.

      * IO::Compress::Gzip

        - Fixed 050interop-gzip.t for Windows
