Amazon WS 3.0 Deprecation

Hello,

Not sure if this is the best place to ask but does anyone know of a Rail plugin that works with the new Amazon ECS 4.0? Here is the deprecation notice / migration guide

I've been using Ruby Amazon (Ruby/Amazon) and Amazon email me saying that they've noticed that my developer ID is still making 3.0 calls.
