Ludwig Nussel has announced the availability of the second alpha build of the upcoming openSUSE 42.2:
openSUSE 42.2 alpha 2 is on the mirrors. Since alpha 1 lots of components from SUSE Linux Enterprise 12 SP2 were integrated, among them an updated YaST, a full GNOME 3.20 update, Samba 4.4, systemd 228, glibc 2.22, Mesa 11.2, CMake. KDE wasn't updated, so testing alpha 2 probably makes more sense on GNOME right now. Bugzilla is awaiting your reports. Some of those updates like CMake and glibc cause other packages to fail building. So the amount of broken packages in 42.2 has increased quite a bit, according to the dashboard we have 181 unresolvable or failed packages right now. Help to analyze and fix the issues is appreciated there. The next alpha is schedule for July 20th, so please submit your fixes and package updates no later than July 15th.
Here is the full release announcement as published on the opensuse-factory mailing list.
