    - This release contains seven fixes for parsing PDFs.  They mostly
      affect files using cross-reference streams, which were first
      supported in the previous release.  Thanks to Marco Pessotto and
      Stuart Henderson for their help identifying and troubleshooting
      bugs.

    - Added contrib/pdf-debug.pl to help track down issues related to
      opening and parsing PDFs.
