Thanks @NathanK, but I’m afraid that leaves me more confused!
In the post you linked to, @clay states:
Local Lightning is the future of Local for three primary reasons: more accessible installation, performance, and stability.
However, in this (albeit a few moths old post) @flyjack states that Local Lightning is deprecated - “no longer supported or maintained”.
And neither of those posts help me understand what to expect the difference between Local 5.2.1 and Local Beta 5.2.1 would be.
I don’t mind at all what terminology you use, and I think that Local is great… it would just be a big help to understand what’s what so I can make an informed choice about what tool(s) to use in different circumstances, and for terminology to be consistent going forward.
