nginx 0.7.7
*) 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.
