WordPress 2.9.2  has been released.
Thomas Mackenzie alerted us to a problem where logged in users can peek at trashed posts belonging to other authors. If you have untrusted users signed up on your blog and sensitive posts in the trash, you should upgrade to 2.9.2. As always, you can visit the Tools->Upgrade menu to upgrade.
