The major outstanding item are the MD-SAL regressions detected in ovsdb (and same thing is biting netconf) and bgpcep, tracked as MDSAL-731 and MDSAL-735 respectivelly. Another day has passed :) so i guess we have to wait until these two are fixed to pick a RC?
Yes, unfortunately and I am still struggling with the fix, it turns out to be more complicated than expected, but I am converging on a solution.
