Battlefield 3's first, er, second major patch is now live server-side and for PC, with console updates coming as soon as the patch finishes the certification process. There's no mention of the tactical flashlight fix, but patch notes confirm that squad selection has received a significant upgrade.
Changes to squad functionality, detailed on the Battlefield blog, include the removal of "find me a squad" and other streamlining enhancements. Squads that are empty will now show up in white and occupied squads in blue, so it'll be easier for friends to quickly select a room to join together.
We've placed the full patch notes after the break, since EA decided you need a Battlelog account to view it otherwise (and we know plenty of people who still can't get that mess to work).
