Connexion Space Explorer in Rhino 6

Hi there,
can someone guide me howto make old (but still functional) Space Explorer to work with Rhino 6?
I recall that during v6 WIP something in Rhino got updated which made Space Explorer (and other older connexion devices) to stop working, but there was some workaround - copying older version of plugin or similar. I can’t find the topic, so maybe someone recalls what to do.
