Fixed that parameters from XML should also be presented in a hash with indifferent access [DHH] Hash#with_indifferent_access now also converts hashes kept in arrays to indifferent access (makes it easier to treat HTML and XML parameters the same) [DHH]

+* Fixed that parameters from XML should also be presented in a hash with indifferent access [DHH]
+
 * Tweak template format rules so that the ACCEPT header is only used if it's text/javascript.  This is so ajax actions without a :format param get recognized as Mime::JS. [Rick]
 
 * The default respond_to blocks don't set a specific extension anymore, so that both 'show.rjs' and 'show.js.rjs' will work. [Rick]
