• HTTP::Date: The str2time function returned wrong values for years in the
  early 20th century, because timelocal() actually expects the year to be
  provided on a different scale than what localtime() returns.
  
• HTTP::Headers can now be constructed with field names that repeat. The
  $h->header function now also accept repeating field names and can also
  remove headers if passed undef as value.
  
• HTML::Form: The parse method now takes hash style optional arguments and
  the old verbose behaviour is now off by default.
  
• HTML::Form: Accept for compatibility with other
  browsers. Patch by Josh Rai josh@rai.name.
  
• HTML::Form: Sane handling of 'disabled' for ListInput. Based on patch by
  Joao Lopes developer@st3tailor.com.br.
  
• HTTP::Negotiate: Fixed matching of partial language tags. Dan Kubb.
  
• HTTP::Response: The as_string method now returns a status line that
  doesn't add the "official" code name in the message field. This improves
  the ability to round-trip response objects via
  HTTP::Response->parse($res->as_string) and makes the first line of the
  string returned agree with $res->status_line.
  
• Net::HTTP: The host attribute can now be set undef in order to suppress
  this header for HTTP/1.0 requests.
  
• Net::HTTP: The default Host: header does not include the port number if
  it is the default (80 for plain HTTP). Some servers get confused by this.
  
• Net::HTTP: Ignore bogus Content-Length headers. Don't get confused by
  leading or trailing whitespace.
  
• LWP::Protocol::http: More efficient sending of small PUT/POST requests by
  trying harder to pass off the whole request in a single call to syswrite.
  
• lwp-request now give better error messages if you used the -o option
  without having the HTML-Tree distribution installed. Also document this
  dependency.
