Updates to Killing Floor have been released. The updates will be applied automatically when your Steam client is restarted. The specific changes include:
Server Browser
* Fixed the in game server browser not showing all servers
* Fixed the "Perks enabled server" icon not showing up in the server browser
* Fixed some server browser filters not working right. Also added the ability to filter servers by Perks enabled and filter by difficulty
* Added the ability to sort the server list by difficulty
* Servers that cannot be reached because they are behind a firewall will show up with a ping of 9999 in the server browser. This is the cause of most "connection failed" messages
* Fixed the "Stats Name/Password" popup box that was popping up but shouldn't have been
* Fixed a "Warning" box that was appearing but shouldn't have been
* Added a message when attempting to host a listen server notifying the user what ports they must have open on their firewall to host the game
Other Fixes
* Shortened the default length of time the server waits before the map changes
* Set proper defaults for Difficulty/Game Length - right now it defaults to Beginner/Short, changing this to Normal/Medium
* Fixed dead enemies disappearing instantly on a Listen Server for other players
* Fixed game not showing up in Gamespy
* White list - creating a white list of server mutators that can be used while still allowing perks
