Did not see any announcements posted   but my wallet started complaining that I'm using an old version (0.8.6.2).

Announcement post still lists 0.8.6.3-mark3 as the current version, and it is available from "start using MED" coin web site page.

Lo and behold, http://www.mediterraneancoin.org/home-1.html has a link to a newer version:
