Just saw the notice about beta 3 being released and saw that I could update automatically from the tools menu. So I did and got the following error:
Upgrade WordPress You have the latest version of WordPress. You do not need to upgrade Warning: Invalid argument supplied for foreach() in /home/username/public_html/wp-admin/update-core.php on line 113
Not a big deal, I can manually do it, but just allerting to a problem.
