Marcus, How are we building 1.2 dev? Is it using always the last version of the ConfigurationOfPharo? If not, how can we do it? :) Once it's done, maybe we can do a #loadLast in the class side of the config like this:

...

loadLastStable (self project version: 'xxx') load

And forget about updating the build script for each version... Cheers! Guille
