Thanks to Vladimir Kochetkov, Positive Research Center.
*) Feature: the "debug_connection" directive now supports IPv6 addresses
and the "unix:" parameter.
*) Feature: the "set_real_ip_from" directive and the "proxy" parameter
of the "geo" directive now support IPv6 addresses.
*) Feature: the "real_ip_recursive", "geoip_proxy", and
"geoip_proxy_recursive" directives.
*) Feature: the "proxy_recursive" parameter of the "geo" directive.
*) Bugfix: a segmentation fault might occur in a worker process if the
"resolver" directive was used.
*) Bugfix: a segmentation fault might occur in a worker process if the
"fastcgi_pass", "scgi_pass", or "uwsgi_pass" directives were used and
backend returned incorrect response.
*) Bugfix: a segmentation fault might occur in a worker process if the
"rewrite" directive was used and new request arguments in a
replacement used variables.
*) Bugfix: nginx might hog CPU if the open file resource limit was
reached.
*) Bugfix: nginx might loop infinitely over backends if the
"proxy_next_upstream" directive with the "http_404" parameter was
used and there were backup servers specified in an upstream block.
*) Bugfix: adding the "down" parameter of the "server" directive might
cause unneeded client redistribution among backend servers if the
"ip_hash" directive was used.

Thanks to Maxim Bublis.
Changes with nginx 1.1.19 12 Apr 2012
*) Security: specially crafted mp4 file might allow to overwrite memory
locations in a worker process if the ngx_http_mp4_module was used,
potentially resulting in arbitrary code execution (CVE-2012-2089).
Thanks to Matthew Daley.

Thanks to Vincent Lee.
*) Bugfix: nginx hogged CPU if all servers in an upstream were marked as

"resolver" directive was used and there was no "error_log" directive
specified at global level.
Thanks to Roman Arutyunyan.
