Hi guys, I think Pharo 2.0 is back in an usable state :)
Beware, that doesn't means that it is stable and bug free! In particular, I think there are still some problems around RPackage and the new SystemAnnouncer, but you can resume using it and providing bug reports/fixes. Enjoy, Esteban ps: That means tomorrow I will resume the integration of issues, etc. but the stability effort is still ongoing...
