Quoted from "Battlefield Blog"

We will soon publish a major client update for the PC version Battlefield 3 as well as a server-side update for all platforms. The update will be made on Nov. 22nd 7:00 AM UTC / Nov. 21st 11:00 PM PST.  We’ll share release timing on the console patches as soon as we are clear on the timing, these take a bit longer due to console certification process.

 

As always, if you have any feedback or want to discuss these changes head to the Battlelog forums. We appreciate your feedback!

NOTE
Battlefield 3 will have a scheduled down time on Nov 22 between 07:00-09:00 AM UTC, during which you will not be able to play the game.

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.

 

That's it for this latest set of updates. Let us know what you think of the changes in the Battlelog forums. Thanks for playing, and see you on the battlefield!
