I've updated the Noticeboard format for M2.5beta - also in beta:
1. First beta for Moodle 2.5beta.
2. Removed '.jumpmenu' from styles.css because of MDL-38907.
3. Added automatic 'Purge all caches' when upgrading. If this appears not to work by lack of display etc. then perform a
manual 'Purge all caches' under 'Home -> Site administration -> Development -> Purge all caches'.
