Sadly, Bitbucket (which host Imebra version control, issue tracker, CI) decided to sunset Mercurial and to support only Git repositories.
Despite considering Mercurial superior to Git in every aspect it was too much of an hassle to look for another provider and migrate all the infrastructure, so I decided to migrate the Imebra version control and keep the rest of the infrastructure in place.
The new Git repository for Imebra is here: https://bitbucket.org/binarno/imebra_git
The old Mercurial repository is here: https://bitbucket.org/binarno/imebra
