As promised, Ubi Soft has released a new patch for Raven Shield updating the game to version 1.4. There's a US upgrade from 1.31 or 1.0, and same for the UK version (1.31, 1.0). Here's a partial list of changes (more here)

General Improvements - Firing animation, sound and muzzle flash should now be completely synchronized with trigger pull. Additionally, the network code for firing bullets has been reworked and less information is now sent for each bullet fired. This will hopefully result in a performance improvement in heavy firefights in restricted bandwidth situations. - We're introducing a spam filter which is configurable in the server.ini and supports a voting option. - We tweaked the silenced weapon damage to hopefully make the silencer a real option in Raven Shield. Silenced weapons should now do a minimum of 50% of the damage their noisy counterparts do. Additionally, the silenced SPP pistol should now be even more "silent". - Drawing tool is now accessible between rounds. - Players will now automatically switch to their primary weapon when they've thrown their last grenade.
