Source Code Repositories moved to Git

As announced on Feb 18, all public source code repositories for Cumulocity IoT that are available on Bitbucket were converted from Mercurial to Git repositories on March 14, 2020.
This was necessary because Bitbucket announced that its web-based version control services would end support for Mercurial in June 2020.
All public repositories are still available at the same URLs and all the branches and history are preserved.
