Daniel (7 March 2006)

- Markus Koetter filed debian bug report #355715 which identified a problem

  with the multi interface and multi-part formposts. The fix from February

  22nd could make the Curl_done() function get called twice on the same

  connection and it was not designed for that and thus tried to call free() on

  an already freed memory area!

- Peter Heuchert made sure the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL

  is used properly.

This release includes the following bugfixes:

 o multi-part formpost with multi interface crash

 o the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL is acknowledged

 o "SSL: couldn't set callback" is now a less serious problem

 o Interix build fix

This release would not have looked like this without help, code, reports and

advice from friends like these:

 Gisle Vanem, Dan Fandrich, Thomas Klausner, Todd Vierling, Peter Heuchert
