What's changed from the previous release is mainly visual stuff, like more complete-looking backgrounds that remove the feeling that the arena is floating in a void (*cough*), as well as a few tiny tweaks to weapon stripping (now impossible to consume Bonk! before the round begins), and some tiny optimization things that will probably affect nothing whatsoever (green fog doesn't om nom nom fps as much when looking directly at it).
As anyone who has made a half-decent map knows, finalizing a map (building cubemaps, etc.) is a pain in the ass, and if you change anything you have to do it all over again. So before I finalize this, I'm going to ask the forums for any reasonable/awesome features that you would like to see added.
Before you say it, I've had suggestions to put in an admin abuse room before (it comes up every damn time, really), but I'm not sure if the effort would be worth it, seeing as the admins already have enough capability to abuse everyone without my help. If you have an admin-abuse-room-like idea that is very specific and creative, I may just take it into consideration. Everything else is fair game.
For reference, here are some screenshots of the new version:
Go and give me some good ideas!
