The 3.50 upgrade also gives you much more control over when and how you join your friends. You can create scheduled events that automatically add your friends to a party, which should be handy for that big Destiny raid or Rocket League tourney. You can see what everyone in a party is playing, too, and get notifications when specific friends are online. And if you're determined to play by yourself, you can choose to appear offline so friends don't get the wrong idea. While you're going to need this update no matter what (if you want to play online, at least), it sounds like it's worth grabbing sooner than later.
