Unless you regularly updated and worked on the latest 2.0 beta this is news ;). You have a complete list of images here http://pharo.gforge.inria.fr/ci/image/20/ including release dates.
During the beta update process it might happen that one or another update fails. Usually that should not happen though.

I did system updates, eventually got (mostly)everything loaded (after a few re-trys), but then the image wouldn't save.
So: it only took me a minute or two to fileOut my application packages and reload them and data into a new image. I should have done this in he first place :-(
or use http://smalltalkhub.com in the first place :)
I ask because I tried running "System update" and that errored off. If I am using an old version of "2" then I will go to the trouble of re-installing and reloading my little project.
