X.Org releases: present and future

I hope that the API will stay stable withing a given server release branch. I agree that coding to the current "API" (in fact just working out what it is) is a bit of a nightmare, but I dread the thought of maintaining an out-of-tree driver against an API, even a somewhat cleaner one, that changes between point releases like 1.8.0 to 1.8.1.
