By using config rather than hardcoded constants, we can evolve the
  configuration system over time (we'd just need to update the config
  method with more robust capabilities and all consumers would get
  the capabilities with no code changes)

  This consists of:

  * String#html_safe! a method to mark a string as 'safe'
  * ActionView::SafeBuffer a string subclass which escapes anything unsafe which is concatenated to it
  * Calls to String#html_safe! throughout the rails helpers
  * a 'raw' helper which lets you concatenate trusted HTML from non-safety-aware sources (e.g. presantized strings in the DB)
  * New ERB implementation based on erubis which uses a SafeBuffer instead of a String

Hat tip to Django for the inspiration.

Don't raise exceptions for missing javascript_include_tag or stylesheet_link_tag sources unless the :cache or :concat options are given. [#2738 state:resolved]

Fix tag helpers so that all HTML element boolean attributes render according to the specs. Added all boolean attributes listed in the XHTML 1.0 specs (http://www.w3.org/TR/xhtml1/guidelines.html) and HTML 5 specs (http://www.whatwg.org/specs/web-apps/current-work). HTML 5 boolean attribute rendering was broken in commit 1e2d7229 / [#2864 state:resolved].

An exception will be raised if a local javascript/stylesheet file included
by the stylesheet_link_tag or javascript_include_tag can not be found.

When caching is enabled, we use atomic_write to ensure that the cache file
is not created with zero length.

Set asset-cached file ctime and mtime to the max mtime of the combined files. Allows for consistent ETag generation without having a shared filesystem.

AbstractRequest.relative_url_root is no longer automatically configured by a HTTP header. It can now be set in your configuration environment with config.action_controller.relative_url_root

Fixed that AssetTagHelper#compute_public_path shouldn't cache the asset_host along with the source or per-request proc's won't run [DHH]

This lets us avoid the relatively costly trip through compute_*_paths if the file already exists.
