0.98.1 [stable branch] Fri Aug 25 2006, joern
    Features:
    - Updated spanish translation. Thanks to Sergio Cambra.

    Bugfixes:
    - Fixed exception when TOC reading failed for some reason.
      Thanks for the report to Jimmi <jimmi AT bglug.it>.
    - Spaces in the VOB file path were not refused but gave
      wrong error messages on TOC reading later. Made special
      character checking on project name and paths more strict.
      Reported by Google Roxxort <larspb AT hotmail.com>.
    - Preferences window: places buttons at the bottom of
      the window. Thanks for the hint to Gert Brinkmann
      <g111 AT netcologne.de>.
    - Preferences window: when changing the DVD drive from
      the popup, result checking output wasn't updated.
    - Added "Add node" button to the cluster control window
      (was lost somehow... ;)
