New Features

  • A middleware_stack plugin has been added for more detailed control over middleware, allowing for the removal of middleware and the insertion of middleware before existing middleware. Example:

    plugin :middleware_stack
    
    # Remove csrf middleware
    middleware_stack.remove{|m, *args| m == Rack::Csrf}
    
    # Insert csrf middleware before logger middleware
    middleware_stack.before{|m, *args| m == Rack::CommonLogger}.
      use(Rack::Csrf, raise: true)
    
    # Insert csrf middleware after logger middleware
    middleware_stack.after{|m, *args| m == Rack::CommonLogger}.
      use(Rack::Csrf, raise: true)

Other Improvements

  • The head plugin now calls close on the response body if the body responds to close. Previously an existing response body was just ignored.
