Domino Design 8.5 Basic?

I am trying to get some information about a non-eclipse version of Domino Designer 8.5? I have seen references to this in some blogs but cannot find any documentation about it in the 8.5 Designer help. What is it, how do I run it? Apart from the UI changes what other differences are there? (I assume it runs faster and crashes less often)…

Subject: Designer 8.5 comes in only Standard mode

Designer 8.5 is only available in Standard (using Eclipse) mode. There is no supported way to run it in basic mode.
