Hi!

I have the book "Unlocking Android" that doesn't cover the SDK v1.5 (Cupcake).

What is new / different from v1.1 regarding development?
What's new / different from v1.5_r1 to v_1.5_r2 regarding development?

I didn't find any information about these topics on the offical site. Do you know that?

Thank you in advance!
