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.
