Wordpress 2.9.2 has been released an hour ago by Wordpress.org.So why this release is, this resolves a security fix for multi user blogs where in case you have some untrusted users (authors, subscribers) on your blog/site so when logged can peek at trashed posts belonging to other authors.Other bugs also have been fixed and can be found here

According to Wordpress.org ” Thomas Mackenzie alerted them about the 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.”

If your have a blog/site which has only an Administrator i.e. you, without any registered users, this upgrade is not necessary.
