After the festive season the dev crew has released an update for WordPress 2.9. WordPress 2.9.1 is a bugfix release and contains no new features. If you have waited updating to 2.9, now is the time to upgrade as most issues have been resolved.
Issues with scheduled posts should be resolved and the same applies to feed parsing errors in the admin dashboard. Update your blogs now via the build-in updater or download the latest WordPress update now.
