 nginx has been updated to version 1.9.7. New this version:

 * Feature: the "nohostname" parameter of logging to syslog.
 * Feature: the "proxy_cache_convert_head" directive.
 * Feature: the $realip_remote_addr variable in the ngx_http_realip_module.
 * Bugfix: the "expires" directive might not work when using variables.
 * Bugfix: a segmentation fault might occur in a worker process when using
 HTTP/2; the bug had appeared in 1.9.6.
 * Bugfix: if nginx was built with the ngx_http_v2_module it was possible
 to use the HTTP/2 protocol even if the "http2" parameter of the "listen"
 directive was not specified.
 * Bugfix: in the ngx_http_v2_module.
