* Change: the --with-ipv6 configure option was removed, now IPv6 support is configured automatically. * Change: now if there are no available servers in an upstream, nginx will not reset number of failures of all servers as it previously did, but will wait for fail_timeout to expire. * Feature: the ngx_stream_ssl_preread_module. * Feature: the "server" directive in the "upstream" context supports the "max_conns" parameter. * Feature: the --with-compat configure option. * Feature: "manager_files", "manager_threshold", and "manager_sleep" parameters of the "proxy_cache_path", "fastcgi_cache_path", "scgi_cache_path", and "uwsgi_cache_path" directives. * Bugfix: flags passed by the --with-ld-opt configure option were not used while building perl module. * Bugfix: in the "add_after_body" directive when used with the "sub_filter" directive. * Bugfix: in the $realip_remote_addr variable. * Bugfix: the "dav_access", "proxy_store_access", "fastcgi_store_access", "scgi_store_access", and "uwsgi_store_access" directives ignored permissions specified for user. * Bugfix: unix domain listen sockets might not be inherited during binary upgrade on Linux. * Bugfix: nginx returned the 400 response on requests with the "-" character in the HTTP method.
