Nginx 1.11.2发布

Nginx 1.11.2 发布了。

本次发布改进记录如下：

       *) Change: now nginx always uses internal MD5 and SHA1 implementations;
       the --with-md5 and --with-sha1 configure options were canceled.

        *) Feature: variables support in the stream module.

        *) Feature: the ngx_stream_map_module.

        *) Feature: the ngx_stream_return_module.

        *) Feature: a port can be specified in the "proxy_bind", "fastcgi_bind",
       "memcached_bind", "scgi_bind", and "uwsgi_bind" directives.

        *) Feature: now nginx uses the IP_BIND_ADDRESS_NO_PORT socket option
       when available.

        *) Bugfix: a segmentation fault might occur in a worker process when
       using HTTP/2 and the "proxy_request_buffering" directive.

        *) Bugfix: the "Content-Length" request header line was always added to
       requests passed to backends, including requests without body, when
       using HTTP/2.

        *) Bugfix: "http request count is zero" alerts might appear in logs when
       using HTTP/2.

        *) Bugfix: unnecessary buffering might occur when using the "sub_filter"
       directive; the issue had appeared in 1.9.4.
