Also, a new version of the Mir display server is scheduled to get implemented in Ubuntu 15.10 Wily Werewolf.
This is Łukasz ‘sil2100’ Zemczak’s announcement:
“Not too many exciting news from the landing team so far. Fixes are flowing-in steadily – all their details can be found in the commitlogs that are auto-generated on every image build below. Wily will be getting the new 0.14.0 mir release soon – the silo with fixes to unblock it from -proposed is waiting for a final archive-admin ACK, after which its vivid-overlay counterpart will be moved forward. Also, a fix for the recent telegram rc-proposed regression has just been signed off and will be landing in the store,”
As a reminder, Canonical is working hard at Unity 8 and Mir right know, the two being available by default only on the Ubuntu Phone, for now.
