nginx 0.5.30 *) Feature: the $args variable can be set with the "set" directive. *) Feature: the $is_args variable. *) Bugfix: if a client has closed connection to mail proxy then nginx might not close connection to backend. *) Bugfix: now nginx escapes space in $memcached_key variable. *) Bugfix: a segmentation fault might occur in worker process when the HTTPS protocol was used in the "proxy_pass" directive. *) Bugfix: the perl $$ variable value in ngx_http_perl_module was equal to the master process identification number. *) Bugfix: fix building on Solaris/amd64 by Sun Studio 11 and early versions; bug appeared in 0.5.29.
