* IO::Uncompress::Base
        - Am input file that had a valid header, and so would allow
          creation of the uncompression object, but was then followed by
          corrupt data would trigger an infinite loop when using the
          input line oprator.
          [RT #61915]

      * IO::Compress::Gzip
        - XFL default settings for max compression & fastest algorithm were
          the wrong way around. Thanks to Andrey Zholos for spotting this.

      * IO::Compress::Base::Common
        - Fixed precedence problem in parameter parsing code.
