It looks like developer DICE has been doing a lot of listening to its customers, as the large number of complaints over in-game glitches has produced an almighty patch, fixing just about everything, including the kitchen sink, while making lots of little tweaks to improve gameplay and the user interface. On top of that, the patch is PC only for now as the console versions are taking "a bit longer due to [the] console certification process".

Bugfixes include such goodies as a "Black Screen" fix for an issue occurring on some PC Configurations; spawn protection improvements; increasing the damage from the 44 Magnum slightly; sharing your profile and stats with new Battlelog functionality; profile integration with Facebook, Google+ and Twitter and lots more. The full list appears below.

A detailed look at Squad refinements

Today's PC client patch features numerous tweaks to Squad functionality and is part of our ongoing efforts to make it easier to play with friends and Platoon mates. These changes will also be implemented for consoles when we release the PlayStation 3 and Xbox 360 updates shortly. Stay tuned for the exact date of the console updates.
First, we need to look at how joining with Squads and Platoons affects the balance of teams. Initially, servers are commanded to equal out each side, so joining with friends can impact that balance while joining with Platoons further hinders this. As a result we have made some adjustments to the in-game Squad management screen.
For PC, you are now able to highlight the various Squads and select which one you wish to join by selecting a Squad and then clicking the Join Squad button. Please note that the Squad Privacy option still allows 2 man Squads which, during 64 player sessions, can lead to players with no squad position -- the number of people with no Squads will be shown at the bottom of the Squad selection list.
After the patch is applied to consoles (in the near future) you will be able to join Squads by cycling through the list and selecting which Squad you wish to join.
