WordPress 2.8.1Published: Tue, 14 Jul 2009 17:34:21 GMT
WordPress have released a bug-fix update to WordPress which fixes many bugs and tightens up security which was allowing certain plug-ins to leak information to unprivaleged users. Not all plugins were affected, but it is recommended that all WordPress users upgrade at their earliest opportunity.
There are reports that the dashboard in the new version is much faster than in 2.8.0, but I haven't noticed a huge difference. I used the automatic upgrade path without any problem - all my plugins worked fine after the upgrade and the theme is unchanged.
