The following are (more-or-less spoiler-free) patch notes for K-ON!!, the recently-finished follow-up to Kyoto Animation's wildly popular series K-ON! about high school girls who usually don't play music. Those looking for advice on the series should first ask themselves the question, "Does a series need to have a plot for me to watch it?" If the answer is no, then familiarize yourself with the first season before upgrading.
