Steffen Ullrich (1):
      correct behavior for https_proxy,
      e.g. don't send plain https:// requests to proxy, but instead establish
      CONNECT tunnel and then send requests inside tunnel.
      This change does together with a change in LWP::Protocol::https.
      The change supports LWP::Protocol::https with the default
      IO::Socket::SSL backend, but also with Net::SSL. Also:
      - proxy authorization is supported (http://user:pass@host:port as proxy
        URL, Net::SSL still needs special HTTPS_PROXY_* environemt variables,
        as before)
      - CONNECT request does not need to be the first request inside the
        tunnel (not with Net::SSL)
      - conn_cache is read and written inside request(), instead of writing in
        request() and reading in _new_socket(). If a https tunnel is
        established the cache_key no longer depends only on proxy host,port
        but also on the tunnel endpoint
      - CONNECT is a proxy request and must always use Proxy-Authorization,
        not Authorization header

turugina (1):
      fix: auth-header of Digest auth did not conform to
      RFC 2617 when WWW-Authenticate has 'qop' parameter.

Gisle Aas (1):
      SSL libs might trigger ENOTTY on read

Michiel Beijen (1):
      Small typo.
