The same usual thing, and please report any bugs found!

Network
+ All servers should be able to join, if host is running on same version and has stable connection
+ New host option: "Run-Shoot Restriction" which is self explanatory

Gameplay
+ Crates & Presents work now, yippy!
+ Strafing or moving back is slower than moving forward, to prevent some chaos and making movement better

Other
+ Main menu has no more halloween docerations, it's now fall themed (maps are still halloween however)
+ Changed the main menus options position
+ How to play page now shows up when starting game for 1st time (for this version, everyone will be shown it)
+ Made stuck issues harder to happen, please tell me if they still happen
+ When sliding your guns are put down

If the update isn't out on library, try restarting Steam and then update might be there.
