by Sven Van Caekenberghe

OK, the board approved the draft, so here is the 1.2.1 release announcement: http://homepage.mac.com/svc/Pharo/pharo-1.2.1-release.html Adrian will put it on the website, next an official mail should be sent to the mailing lists. Then we should all try to spread the word! Even if it was a bit long winding in the end, this is a release to be proud of. Sven
