nginx 1.3.2 *) Change: the "single" parameter of the "keepalive" directive is now ignored. *) Change: SSL compression is now disabled when using all versions of OpenSSL, including ones prior to 1.0.0. *) 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. *) Bugfix: an alert "sendmsg() failed (9: Bad file number)" on HP-UX while reconfiguration.
