More work still needs to be done on some of these names
(render_template.action_view and render_template!.action_view particularly)
but this allows (for example) /^sql/ to subscribe to all
the various ORMs without further modification

Added explict setting of charset in set_fields! method to make sure Mail has the user defined default

Removing quoting.rb, upgrade to 2.1.3.6, changing all utf-8 references to UTF-8, updating tests where incorrect encoding

should run during framework load do:

ActiveSupport.on_load(:action_controller) do
  # Code run in the context of AC::Base
end

Ensure details are frozen after @details_keys lookup. The implementation waits to freeze until the last required moment, to avoid duping hashes.

Improve performance of the rendering stack by freezing formats as a sign that they shouldn't be further modified.

Allow anything that responds to render to be given as :template and use find_template instead of find in views.

add lazy_load_hooks.rb, which allows us to declare code that
should be run at some later time. For instance, this allows
us to defer requiring ActiveRecord::Base at boot time purely
to apply configuration. Instead, we register a hook that should
apply configuration once ActiveRecord::Base is loaded.

With these changes, brings down total boot time of a
new app to 300ms in production and 400ms in dev.

TODO: rename base_hook

Adding options to register observers and interceptors through ActionMailer::Base.register_observer and ActionMailer::Base.register_interceptor.  These hook into Mail.register_interceptor and Mail.register_observer.  Also bumped Mail requirement to 2.1.3

Fixed up being able to pass random headers in with headers, or mail.  Also, undeprecated headers(hash) as this works now too
