Since 2.9′s release a lot of users have been complaining that they were unable to use the scheduled posts feature. While you could schedule the post, it would not publish at the time you wanted. In fact, you would have to go in and adjust manually publish.

Other problems that have been addressed can be found at the WordPress trac. Please note that if you are having actual upgrade issues to be specific about your problem or it will be difficult to resolve. If it is just plugin issues, either contact the plugin creator, or go to the WordPress Support Forums and post a new topic. Please note, some plugin creators may not provide support or request you to join their own forum.

The update should be available as an automatic download or for those still having trouble, you can download and manually upgrade your WordPress installation.
