  * request.formats is much simpler now
    * For XHRs or Accept headers with a single item, we use the Accept header
    * For other requests, we use params[:format] or fallback to HTML
    * This is primarily to work around the fact that browsers provide completely
      broken Accept headers, so we have to whitelist the few cases we can
      specifically isolate and treat other requests as coming from the browser
    * For APIs, we can support single-item Accept headers, which disambiguates
      from the browsers
  * Requests to an action that only has an XML template from the browser will
    no longer find the template. This worked previously because most browsers
    provide a catch-all */*, but this was mostly accidental behavior. If you
    want to serve XML, either use the :xml format in links, or explicitly
    specify the XML template: render "template.xml".

Include process methods in ActionController::TestCase only. No need to alias_method_chain :process either.

The accept header is poorly implemented by browsers and causes strange errors when used on public sites where crawlers make requests too.  You should use formatted urls (e.g. /people/1.xml) to support API clients. Alternatively to re-enable it you need to set:

config.action_controller.use_accept_header = true

A special case remains for ajax requests which will have a javascript format for the base resource (/people/1) if the X-Requested-With header is present.  This lets ajax pages still use format.js despite there being no params[:format]

Added proper getters and setters for content type and charset [DHH] Added utf-8 as the default charset for all renders. You can change this default using ActionController::Base.default_charset=(encoding) [DHH]
