The main focus for this update was the targeting of some of the connectivity issues that have been experienced over the last month. The patch also provides a better distribution of respawn points across all game modes. It also fixes the the issue that some players reported with load-out slots not being unlocked, in addition to problems with the melee medal (which was always being awarded as a "bronze"). And there are also a number of stability fixes, to address some of the crashes that have been reported.
Note that the previous workaround information regarding connectivity is now redundant and it is recommended that any steps you may have followed in order to connect should now be reverted.
