"In addition to closing a DOS vulnerability (thanks to Jim Meyering),
this upstream feature release adds the following enhancements :

  - Support for side-by-side diffs

    - Support for repo content in 'about' view

    - Improved integration with gitolite/gitweb

    - Support for git notes in commit/log view

    - Support for graph in log view (similar to 'git log
      --graph')

    - Improved handling/display of path filters

    - Clients can modify diff view parameters

    - Support for directory listings in plain view

    - Support for remote branches

    - Support for range searches in log view (like 'git log
      master ^stable)

    - Support for expansion of environment vars in certain
      cgitrc options, which can simplify virtual hosting

The release announcement has a more complete changelog :

http://article.gmane.org/gmane.comp.version-control.git/168496

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
