WordPress announced the release of WordPress 2.9.1. This release addresses a handful of minor issues as well as a rather annoying problem where scheduled posts and pingbacks are not processed correctly due to incompatibilities with some hosts. Download 2.9.1 or upgrade automatically from the Tools->Upgrade menu in your blog’s admin area. http://wordpress.org/development/2010/01/wordpress-2-9-1/, http://wordpress.org/download/
