• Show cache hits and misses when rendering partials.

  Partials using the cache helper will show whether a render hit or missed the cache:

  Rendered messages/_message.html.erb in 1.2 ms [cache hit]
  Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss]
  

  This removes the need for the old fragment cache logging:

  Read fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/d0bdf2974e1ef6d31685c3b392ad0b74 (0.6ms)
  Rendered messages/_message.html.erb in 1.2 ms [cache hit]
  Write fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/3b4e249ac9d168c617e32e84b99218b5 (1.1ms)
  Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss]
  

  Though that full output can be reenabled with config.action_controller.enable_fragment_cache_logging = true.

• Don't override the Accept header in integration tests when called with xhr: true.

  Fixes #25859.

• Fix 'defaults' option for root route.

  A regression from some refactoring for the 5.0 release, this change fixes the use of 'defaults' (default parameters) in the 'root' routing method.

• Check request.path_parameters encoding at the point they're set.

  Check for any non-UTF8 characters in path parameters at the point they're set in env. Previously they were checked for when used to get a controller class, but this meant routes that went directly to a Rack app, or skipped controller instantiation for some other reason, had to defend against non-UTF8 characters themselves.

• Don't raise ActionController::UnknownHttpMethod from ActionDispatch::Static

  Pass Rack::Request objects to ActionDispatch::FileHandler to avoid it raising ActionController::UnknownHttpMethod. If an unknown method is passed, it should exception higher in the stack instead, once we've had a chance to define exception handling behaviour.

• Handle Rack::QueryParser errors in ActionDispatch::ExceptionWrapper

  Updated ActionDispatch::ExceptionWrapper to handle the Rack 2.0 namespace for ParameterTypeError and InvalidParameterError errors.
