Two changes have been made today.

First, we now handle old-style URLs more gracefully.
For example:
- If you go to an old-style profile URL, we'll figure out which profile you want, and send you there.
- If you go to an old-style groups URL, we'll send you to the groups homepage.
- If you go to an old-style wiki, gallery, etc URL, we'll tell you outright that this content no longer exists, using a HTTP 410 ("Gone") error code.
This should address cases where users, search engines, etc were looking at old-style links and finding that they no longer work.

Second, we've done a minor software update. There are no visual changes here, it just a back-end update.

As always, if you notice anything odd about either update, post about it in the admin stuff forum.
