A big new update for the music game Rock Band 4 is out now, adding a new Seasons mode and a Mission system, while a number of bugs are fixed with the patch as well. Seasons, a change to the Rivals Challenge format, in Rock Band 4 run for eight weeks. You start with the Bronze ranking and move up from there; no longer can you be demoted if you take time off, which sounds like a nice thing. Of course there are rewards to rack up for moving through the ranks, and you can read more about them here on Harmonix's website.

As for the new Missions system, this is a list of tasks you can take on, examples playing five big rock endings and one that asks you to miss just one note in a song. Some Missions tie in to your Crew, where each member contributes to an overall XP goal. There are also timed missions, themed missions, and "Secret" missions, Harmonix says.

Here are some other notable highlights from Rock Band 4's new update:
  • You can now press one button to look at the different items in the Activity Feed
  • The Feed has been streamlined, so you will no longer see notifications for when someone earned an allotment of XP, while Rivals notifications are going to be "far less frequent"
  • In the Music Store, recommendations now have "better individual tailoring"
  • The Rock Band companion app is updated with the ability to enter the Rivals hub and see scores and percentiles, XP earned, and an overall ranking bar
  • Vocal Overdrive has changed so you can disable audio activation so that a door slam or any other unexpected noise won't activate the Overdrive
  • Stuttering and drag should be improved thanks to Harmonix doing "deep, deep code dives"
