The time has been well spent working on a stability patch, 1.10, which is due for release this week. The patch is currently undergoing final testing. [...] As you'll see, we've addressed many of the issues reported by the community, and many more. You'll see the release notes once the patch comes out, but these are some of the highlights:

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.
