New Features¶ ↑

• The assets plugin now supports a :compiled_asset_host option, which specifies a hostname used to serve compiled assets.

• The render plugin now supports a :cache_class option, which specificies a class to use for the thread-safe template cache. This can be used to setup LRU caching or caching that checks modify times on the underlying template files.

• r.multi_run in the multi_run plugin now accepts a block, and calls the block before dispatching to the related rack application. This can be used to modify the environment before dispatching. Example:

  r.multi_run do |prefix|
    env['authenticated'] = true
  end
  

Backwards Compatibility¶ ↑

• The :by_name option to the path plugin now defaults to true in development mode. This should only negatively affect applications that register anonymous classes with the path plugin.
