WordPress 2.2.3 and WordPress MU 1.2.5

Are you WordPress user? These are some info for you. Last week — I know, it’s probably an old news — WordPress 2.2.3 had been released. This release includes some bug fixes and security issues (see the closed bugs).
If you’re running an older version, download it and upgrade your WordPress installation.
Another release is related to WordPress MU. The latest WordPress MU distribution (1.2.5) released for public on September 10, 2007.
I maintain some WordPress-powered sites, and I am thinking of upgrading all of them this weekend. I hope everything will go smoothly.
