A new small update today that fixes some annoying bugs with PHP 5.3 and PHP 5.4; It also solves the problem of previewing the posts and pages being edited.

Do not forget to empty the cache of the templates (Maintenance plugin) as well as the cache of your browser after having made an update. In case you have opted for a manual update, do not forget to disconnect and reconnect, some updates (concerning the database) are made at this time.
