- David Byron reported a problem with proxy authentication when doing CONNECT,

  like when accessing HTTPS sites wiht a proxy. This probably broke when I

  rewrote the auth stuff recently.

- libcurl now supports "uploading" to file:// URLs.

- Simon Josefsson added a idn_free() function in libidn 0.4.5 as a reaction to

  Gisle's previous mail. We now use this function, and thus we require libidn

  0.4.5 or later. No earler version will do.

  0.4.5 or later. No earlier version will do.

- Robert D. Young reported that CURLOPT_COOKIEFILE and CURLOPT_COOKIE could

  not be used both in one request. Fixed it and added test case 172 to verify.
