WordPress 3.0.2 is made available today, and it is a mandatory security update for all previous WordPress versions. This maintenance release fixes a moderate security issue where a malicious Author-level user could gain further access to the site. This release also addresses a handful of bugs, and provides some additional security enhancements. Big thanks to Vladimir Kolesnikov for detailed and responsible disclosure of the security issue!
We advise that you update immediately even if you do not have untrusted users. (Use our ultimate guide to Upgrade WordPress to make sure you do everything right)

Has anyone else experienced this?
I installed this update on three test blogs and when the upgrade was complete I was unable to access the main page, the admin page or even the FTP.
I contacted my host’s support and they said those three blogs had somehow had their permissions changed. Didn’t happen to any of my others that did not receive the upgrade. :/

Hi there, does the nightly-build of WP 3.1 already include the fix?
