    * Documentation links now point to online resources
    * Matt Wall's Exfoliation theme is now installed by default. You can reinstall the classic theme with "make install-classicui"

FIXES

    * Fixes status.cgi when called with no parameters, where host should be set to all if none specified (Michael Friedrich)
    * Fixes possible validation error with empty hostgroups/servicegroups (Sven-G�ran Bergh)
    * Performance-data handling and checking is now thread-safe so long as embedded perl is not used.
    * Children should no longer hang on mutex locks held in parent for localtime() (and similar) calls.

    * Removed duplicated unlinks for check result files with multiple results
    * Fixed race condition on flexible downtime commands when duration not set or zero (Michael Friedrich)
