Previously (prior to the new release structure) the EAP builds came almost every week. Even after releasing a major version the next version was already being developed in parallel, so the next EAP came 1-2 weeks after that major release. I suspect this parallel track is true this time as well from "fixed in" fields in YouTrack. Did this silently change with the new release structure?
Why do you need "enough new features"? Is the built so unstable that it doesn't even qualify for EAP?
