I just deployed new version of Copr.
There are just two small bugfixes, but one biggest improvement - add db indexes :) which make the service much faster.
Additionaly Adam is working on set of Beaker tests - currently not public, but I would like them to move to Fedora Beaker one day. The benefit is that we can now test not just copr-frontend, but also copr-backend in staging environment before going live.
