The source code was - and is still also hosted - on GitHub.
There are a few reasons for the move;
- I was looking for an easy way to store binary releases. Binary releases aren’t supported by GitHub. There might be a solution for this at GitLab but scp to upload a release is more convenient.
- GitHub is becoming too dominant.
- I prefer a solution that is based on Free Software.
- I was already using GNU savannah for another project lookat.
