 * `config.asset_host` sets the host for the assets. Useful when CDNs are used for hosting assets, or when you want to work around the concurrency constraints builtin in browsers using different domain aliases. Shorter version of `config.action_controller.asset_host`.
 
-* `config.asset_path` lets you decorate asset paths. This can be a callable, a string, or be `nil` which is the default. For example, the normal path for `blog.js` would be `/javascripts/blog.js`, let that absolute path be `path`. If `config.asset_path` is a callable, Rails calls it when generating asset paths passing `path` as argument. If `config.asset_path` is a string, it is expected to be a `sprintf` format string with a `%s` where `path` will get inserted. In either case, Rails outputs the decorated path. Shorter version of `config.action_controller.asset_path`.

 * `config.autoload_once_paths` accepts an array of paths from which Rails will autoload constants that won't be wiped per request. Relevant if `config.cache_classes` is false, which is the case in development mode by default. Otherwise, all autoloading happens only once. All elements of this array must also be in `autoload_paths`. Default is an empty array.

-* `config.queue` configures a different queue implementation for the application. Defaults to `ActiveSupport::SynchronousQueue`. Note that, if the default queue is changed, the default `queue_consumer` is not going to be initialized, it is up to the new queue implementation to handle starting and shutting down its own consumer(s).

 * `config.reload_classes_only_on_change` enables or disables reloading of classes only when tracked files change. By default tracks everything on autoload paths and is set to true. If `config.cache_classes` is true, this option is ignored.
