- Squid now drops any requests using transfer-encoding.
  Squid is a HTTP/1.0 proxy and as such do not support
  the use of transfer-encoding.
- The MSNT auth helper has been updated to v2.0.3+fixes for
  buffer overflow security issues found in this helper.
- A security issue in how Squid forwards proxy authentication
  credentials has been fixed
- Minor changes to support Apple MAC OS X and some other platforms
  more easily.
- The client -T option has been implemented
- HTCP related bugfixes in "squid -k reconfigure"
- Several bugfixes and cleanup of the Gopher client, both
  to correct some security issues and to make Squid properly
  render certain Gopher menus.
- FTP data channels are now sanity checked to match the address of
  the requested FTP server. This to prevent theft or injection of
  data. See the new ftp_sanitycheck directive if this is not desired.
- Security fixes in how Squid parses FTP directory listings into HTML
