Yup, here's the proof:

This patch is still a work in progress, so not everything that will hopefully make it in when it's done is included here (and I'm not going to call out each of the minute bug fixes), but we wanted to give everyone some idea of the bigger things to expect from 1.05:
Party leader may now optionally allow other party members to invite other players into the party
Classic mode mic system changed to be open
Knife swipe exploit fixed (the knife no longer silences footsteps)
SMG accuracy reduced over distance - tuned for up-close battles rather than long-distance kills
Fixed Classic Bomb Squad double round win bug
Fixed grenade launcher bug where firing over cover or at long distances could kill you
Firing mechanic changes introduced in 1.04 have been rolled back (tapping to fire is now more accurate again)
Several level collision issues fixed
Games queues will be able to be adjusted much more easily and quickly (i.e. we'll be refreshing the queues right after launch)
There have also been lots of bug fixes to the party system, clan system, UI in general and between-round transitions (i.e. less crashes).
Also, a big item that's currently under investigation is the number of headshots in the game. We all know that there are too many, so the team is looking at how we might be able to counter that for the patch. It's not an issue with the size of the hitbox (that's been checked over and over), so it's not a simple fix, and any changes to the damage system in general could have adverse effects on other parts of the game if not handled carefully. So, as mentioned, that's a big TBD on if and how it would be changed, but it's certainly being looked at and will be dealt with if possible.
