A new whitelist has been published as of July 1st, 2014. Just to clarify, all that has been changed for 4v4 is the Conga Taunt has been banned. No weapons have been added to or removed from the whitelist. Please visit the downloads page to grab the new whitelist for your servers!
Complaints from players that enemies were getting stuck in the taunt pose accidentally are the main reason for this. Thanks for your feedback, everyone.
