Changes with nginx 0.7.7 30 Jul 2008

    *) Change: now the EAGAIN error returned by connect() is not considered
       as temporary error.

    *) Change: now the $ssl_client_cert variable value is a certificate
       with TAB character intended before each line except first one; an
       unchanged certificate is available in the $ssl_client_raw_cert
       variable.

    *) Feature: the "ask" parameter in the "ssl_verify_client" directive.

    *) Feature: byte-range processing improvements.
       Thanks to Maxim Dounin.

    *) Feature: the "directio" directive.

    *) Feature: MacOSX 1.5 sendfile() support.

    *) Bugfix: now in MacOSX and Cygwin locations are tested in case
       insensitive mode; however, the compare is provided by single-byte
       locales only.

    *) Bugfix: mail proxy SSL connections hanged, if select, poll, or
       /dev/poll methods were used.

    *) Bugfix: UTF-8 encoding usage in the ngx_http_autoindex_module.
