[android-developers] Best practice for changing min SDK

I have a sizable install base already on some apps with Android 1.5
set as the minimum version. I want to update the apps to take
advantage of some of the newer features offered in Android 2.0 and
greater. What is the best way forward so I don't break things for my
current 1.5 and 1.6 users?

If I simply update the application with a new min SDK version, will
1.5 and 1.6 users be prompted to uninstall? Or will they just not see
the update?

What about future development that I want to apply for everyone, say a
bugfix. Will I have painted myself into a corner?

Another solution would be to fork and create a new app for 2.0 users,
but that is undesirable for several reasons.

This must be a somewhat common problem. Have you seen any good ways to
handle it?
