* Non-String attributes are now converted to Strings; this means code such as

elem.attributes["a"] = 1
  will not cause an error when dumping the XML.  It also means that:
  elem.attributes["a"]    # => "1", not 1
* Transitive indenting has been cleaned up.
* Fixed a potential bug in parsing non-ASCII encoded streams
* Fixed a bug where trying to fill in ParseException data was causing an
  IO error (stream closed)
* Changes to Text mean that Element (and Text) can be used outside of a
  Document context.
* In some rare cases, the base parser wasn't reading enough bytes from the
  stream for the parsing algorithm to work properly.  This has been fixed
  (this was Ruby bug #48426)
