+0.4.0
+=======
+- Treat each header as it's own before_filter. This allows you to `skip_before_filter :set_X_header, :only => :bad_idea
+- Should be backwards compatible, but it is a change to the API.

 0.3.0
 =======
 - Greatly reduce the need to use the forward_endpoint attribute. If you are posting from your site to a host that matches TLD+1 (e.g. translate.twitter.com matches twitter.com), use a protocol relative value for report-uri. This will alleviate the need to use forwarding. If your host doesn't match, you still need to use forwarding due to host mismatches for Firefox.
