AppStore Update Policy

Just wondering what will happen if the current app version supports OS 10.6.6 upwards and you upload a version that is built for Lion.

Will the 10.6 users be still able to download the version that is for 10.6 or will they be forced to upgrade to 10.7? My guess is the latter, but I'm not 100% sure.

How would you ha开发者_如何转开发ndle the jump from 10.6 to 10.7?

Apple's storefront database knows which version of OS X your app currently requires (the Deployment Target), and thus might not allow the App Store application on your Mac to update an app if the Mac on which the App Store application is running does not have a proper OS version for that app.

Any update replaces the previous version. If the new version you plan to release requires 10.7, then I strongly encourage you to disclose that information in the update so that users who plan not to upgrade right away will know not to install your update.
