New API isn't 'deprecated', but just marked evolving and is unstable (things may change between releases).
Using the old, stable API is a good idea for 0.20.x/1.x stable releases as they are more complete in it. However, we've added some more backports to new API in 1.0.1 to help those who use it. The project continues to support both APIs fully through 0.23 (and maybe beyond).
