*) Feature: it is now possible to use the "ip_hash" directive to balance
IPv6 clients.
*) Feature: the $status variable can now be used not only in the
"log_format" directive.
*) Bugfix: a segmentation fault might occur in a worker process on
shutdown if the "resolver" directive was used.
*) Bugfix: a segmentation fault might occur in a worker process if the
ngx_http_mp4_module was used.
*) Bugfix: in the ngx_http_mp4_module.
*) Bugfix: a segmentation fault might occur in a worker process if
conflicting wildcard server names were used.
*) Bugfix: nginx might be terminated abnormally on a SIGBUS signal on
ARM platform.
