[siegenthalerroger]

Are release candidates being considered for these minor versions? Considering some of the issues found on the previous minor release, this might be a possible improvement.

I'm happy to raise this in a discussion or on slack if that's preferable.

Are release candidates being considered for these minor versions?

Not with the current team of core maintainers. A release takes about 2 full days for 2-3 people. We just don't have enough people to do work full-time on Flux.

That's very understandable :)
