If you have existing Metals, you have a few options:
* if your metal behaves like a middleware, add it to the
  middleware stack via config.middleware.use. You can use
  methods on the middleware stack to control exactly where
  it should go
* if it behaves like a Rack endpoint, you can link to it
  in the router. This will result in more optimal routing
  time, and allows you to remove code in your endpoint
  that matches specific URLs in favor of the more powerful
  handling in the router itself.

For the future, you can use ActionController::Metal to get
a very fast controller with the ability to opt-in to specific
controller features without paying the penalty of the full
controller stack.

Since Rails 3 is closer to Rack, the Metal abstraction is
no longer needed.

e.g. it guesses that a belongs_to association to Namespace::MyModel is
named "my_model", unlike before where it would look up an association
named "namespace::mymodel" and fail.

Add test that shows how link text can contain HTML if needed:
the trick is using block form in combination with `raw`.
Let link text be automatically HTML-escaped

_helper module included in the view.

- ensures that protect_against_forgery? is present when a helper
  included in a partial that is rendered by the template under test
  calls it (which happens in FormTagHelper#extra_tags_for_form, for
  example).

A small rdoc change made on lines 39 and 41 on activesupport/lib/active_support/core_ext/object/to_param.rb. It looks like the method name might have been changed, and the comments were never changed to coincide with the new method name.

Cover more of the Rails initialization process, regarding the internals of YourApp::Application inheritance from Rails::Application and more.

ActionView::TestCase::TestController without stubs. Just say:

  @controller.controller_path = "path/i/need/for/this/test"

- enables alternative testing frameworks to include AV::TC::Behavior
  instead of subclassing AV::TC
- also added tests and code for:
  - test view delegates :notice to request.flash
    - useful since generators generate views that use notice
  - test case doesn't try to include modules that are actually
    classes

Fix a bug where I18n fallbacks modules where not included in the proper backend if it was set through config.i18n.backend.

Makes String#mb_chars on Ruby 1.9 return an instance of ActiveSupport::Multibyte::Chars to work around 1.9's lack of Unicode case folding.

Refactors class methods from ActiveSupport::Multibyte::Chars into new Unicode module, adding other related functionality for consistency.
