upgraded to 2017.3 EAP after seeing the announcement on mailing list, and cursive is not present in preferences / plugins or "browse repositories"

the Cursive plugin was installed in my 2017.2.x IntelliJ

ok, got it working, had to quit IntelliJ and delete ~/Library/Preferences/IntelliJIdea2017.3 and ~/Library/Application Support/IntelliJIdea2017.3, those were lingering there from my previous attempt to upgrade IntelliJ without Cursive being available. Not sure why it got into such bad state that the plugin wasn't listed and wasn't offered to be installed...
