TL;DR Koschei now supports targets other than rawhide (not enabled yet) and should correctly handle weak and rich deps. Full version: Last week Koschei [1] was updated to latest upstream release (1.6.1). The new version comes with one particularly interesting feature - Koschei is now able to track more than one package collection at time, which means that it could be possible to use it for Fedora branches other than just rawhide, for EPEL, or even for side tags in Koji. Currently only rawhide is enabled, but if there's enough interest then it should be possible to enable other targets too. Along with the update, Koschei backend was reinstalled on Fedora 23 system (instead of RHEL 7), which allowed us to use features of latest hawkey and libsolv - from now on Koschei correctly ignores weak dependencies and supports rich dependencies.
