Not much is new to 15.10. It really comes off as a nice, polished, stop-gap before 16.04 -- which is when a lot of things will get interesting.<p>I'm expecting this release to be treated similarly to some other non-LTS releases. 12.10 has a reputation for altcoin mining. 14.04 is suggested for gaming. 15.10 will probably become the <i>de jure</i> for Ubuntu + X.<p>Short blurp about changes: <a href="http://www.omgubuntu.co.uk/2015/10/ubuntu-15-10-download-review-new-features" rel="nofollow">http://www.omgubuntu.co.uk/2015/10/ubuntu-15-10-download-rev...</a>
