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, it seems:

This is a pre-release version of Xcode 4.1 for both Mac and iOS development. This release requires Mac OS X Lion and includes iOS SDK 4.2. Continue to use Xcode 3.2.5 on a Snow Leopard partition if you plan to submit Mac or iOS apps to the App Store

UPDATE: This question was asked in Jul 2011. As of now, Nov 2011, Xcode 4.2 is already released and made available on the Mac App store.
