As announced on sys-announce, to address security flaw in WordPress 3.6 and
earlier, blog.inf.ed.ac.uk has been updated to the current version of WordPress (3.6.1).
There will be some small changes, and you many notice pop-ups highlighting new options.
If you run your own WordPress installation within Informatics, then you must
upgrade your version too, as the exploit allows remote execution of code on our
servers. If we become aware of old WordPress installations on our servers, then
we will have to take steps to protect ourselves from this exploit, and disable
your WordPress installation.
See http://wordpress.org/news/2013/09/wordpress-3-6-1/ for more details on the
update and exploit.
