I reattached a clean version of the old history to the pharo-vm repository https://github.com/pharo-project/pharo-vm/network As a result all the SHA hashes of the commits changed :/ AFAIK you should be fine with your local copies by pulling the latest changes from pharo-vm and merge. Additionally we have now 2 branches following according to git-flow: - master: containing the stable version - develop: containing the latest dev version
