v2.0.0

• BREAKING config.redis has been replaced with config.cache, replacing the
  direct Redis dependency with an instance of a ActiveSupport::Cache::Store. If you
  wish to keep using Redis, you should wrap it like so:

-config.redis = Redis.new
+config.cache = ActiveSupport::Cache::RedisCacheStore.new

Alternatively, you can also use Rails.cache to use a different backend:

-config.redis = Redis.new
+config.cache = Rails.cache
