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]

+* 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]
+
 * Hash#to_xml supports YAML attributes.  #7502 [jonathan]
 
 * Refactor ActiveSupport::JSON to be less obtuse.  Add support for JSON decoding by way of Syck with ActiveSupport::JSON.decode(json_string).  Prevent hash keys that are JavaScript reserved words from being unquoted during encoding.  [Sam Stephenson]
