If I have an old project that worked with web framework 1.0 and API 1, and if I upgrade the app to web 2.0, do I also have to make the project compatible with API 2.0, or will it still work with API 1?
Web 2.0 will be API 2.0 only. There’s a large thread of questions and answers where this and many other topics are discussed.
look at post there from Geoff Mar 30
