Great Vladimir, I’ve given the pre-release notes (below) each a test on a vanilla multisite and dev copy of client site and confirm we’re no longer losing capabilities, awesome!
I see your disclaimer here https://www.role-editor.com/download-plugin/, but I assume this beta release *could* be rolled out to a production site, in that reverting to an actual release will not cause an issue and that it is in the “upgrade path” so to speak?
