[ Stig Sandbeck Mathisen ]

  If used with librrds-perl 1.2 or older, the font path is wrong.

[ Tom Feiner ]
* Update watch file.
* Add patch from munin ticket #828, to suppress "occasional" unknown

* Removed asterisks from NEWS.Debian and rewrite as non bulleted list, as
  advised by the developers reference.
