At now the latest published item in releases is 'v3.0.2': . However, https://github.com/VUnit/vunit/releases/latest is redirected to v0.51.3. As a result, it is not straightforward to download the latest stable release programatically, i.e., curl -s https://api.github.com/repos/vunit/vunit/releases/latest | grep "tag_name".
I believe this is not a critical issue, because most of the users will install the library through pip. Still, it might be worth checking the integration with travis-ci.
