JRuby 10.1 has moved to master and Ruby 4.0 work will probably merge this week. We're aiming for a Ruby 4.0-compatible 10.1.0.0 release in the next month, depending on whether I get all these fun optimizations done in time. Ruby 4.0 has only a few dozen fails that could be fixed post-release. Help wanted! github.com/jruby/jruby/issues/9061
@scuttlebutt I get it, no worries! It's not a common way to version but it has worked for us. We sometimes drop extra zeros but I usually prefer to be specific.
