Is moving to Lion a prerequisite for moving to XCode 4.1 (from the app store)?

Question

should you only download XCode 4.1 from the app store if you move to Lion?

i.e I am staying on Leopard for a few more weeks, so do I have to stay with XCode 4.0.2 unti

Answer 1

Yes. Xcode 4.1 Requires Lion. This has been well documented, but 4.2 is apparently available for Snow Leopard as well.
