Today we released a small but vital patch for ZP:S which resolved some potentially serious issues. We also removed an exploit in Harvest that was getting around like OkeiDo in heat. So if you have a ZP:S server make sure that it's updated to version 1.5.1 and for everyone else just launch ZPS and steam will do the rest.
=====Changelog v1.5.1 (2-6-2009) ======
-Fixed Winchester reload exploit
-Fixed the problem where shell weight wasn't eliminated when Winchester was fired.
-Fixed a few map exploits/issues in Harvest.
-Fixed a few exploits in new version of Cinema.
-Made several exploitable server commands "cheat only".
-Added a "<team name> wins" message to server logs when a team wins.
Also we've been receiving a lot of good constructive criticism so keep it coming guys, we really appreciate the interest you've shown to even the littlest of things.
