• Fixed jumping fatigue not being applied.
• Made an optimization pass to the game movement code.

Game rules

• Removed Source SDK 2013's internal game stats system (used internally by Valve for QA purposes).

This fix added a "side-effect": if you mute a player, it will also "gag" him (you will no longer receive text messages from him in the text chat). This change has been added by Valve since Source SDK 2013 and if you want to revert to the old Source SDK 2007/ZPS v2.4 behavior where muting the voice does not "gag" the messages as well, you can check off the "Mute voice also mute text" check box in ZP Options (or set the "cl_mute_all_comms" client CVAR to "0" if you are familiar with the console).
• Fixed voice menus still being shown while dying.
• Moved the Zombie Vision highlight doors option from "Miscellanous (More)" panel to "Inventory / Zombie Vision" tab.
