This "stability update" adds on bandwidth functionality, connectivity performance, and a bunch more good stuff sure to make your experience more enjoyable.
* Bandwidth - Optimisations which reduce the amount of traffic being sent around the network, thus reducing any lag problems.
* Stability - Fixes for rare 'Dirty Disc' errors and rare game crashes.
* Connectivity - Prevent players trying to get into lobbies when they won't be able to see everybody, improving matchmaking times.
* Disconnects - We now show more informative messages when players are disconnected from game sessions.
* Host Migration - Fixed occasional random disconnects when migrating to a new host.
* Split Lobbies - Reduced the frequency of 'split lobbies' which were occurring occasionally.
