GRiN_Stickan posted this over at gr.net. And He also stated that this in not the "june patch". Here are some of the fixes that will be in the patch.
* ALL key configurations will be overwritten. If you've bound your keys different than default, you must do it again. This is to open for the two new keybinding functions we've introduced. These are remapping the mousewheel to different buttons(CrossCom), and a new key "u" to toggle chat on and off in multiplayer.
* Multiplayer has recieved stability updates and fixes. We've found and fixed a number of issues that could cause disconnects, worse performance over time, and some crashes.
* You can no longer be a "ghost" in multiplayer, throwing grenades to fake "fatal accidents".
* You no longer have to press "Enter" to confirm input in the multiplayer interface.
