I released new major version of Cupt, 2.0.0 (== 2.0.0~rc2), today. The final list of major changes since 1.5.x is available
here and in binary packages. A web copy of the (newly written) tutorial is
here.
Thanks to all bug reporters who helped to make it better.
Packages have landed to Debian unstable and should be available on the mirrors soon.
