1 - Lots of new themes, Some I personally don't like (like defaultv3 and manillav2)
DarkMetal is the forum's new default theme. It truly just hits that spot for me.

New mail place. You now can register your very own cy-x.net email account for absolutely free!

I personally revamped the permissions system and mod panel. If something doesn't work or you don't have permission to do something you obviously should please let me know

Also, new Status page to let you all know what services are available or not.

New homepage, new Articles page, isnce that wasn't there before.

The captcha system now properly uses hashes instead of storing in plaintext, just in case! (i don't know)

Report any issues you may have had with this system to me if any.
