nginx 1.3.1
*) Security: now nginx/Windows ignores trailing dot in URI path
component, and does not allow URIs with ":$" in it.
Thanks to Vladimir Kochetkov, Positive Research Center.
*) Feature: the "proxy_pass", "fastcgi_pass", "scgi_pass", "uwsgi_pass"
directives, and the "server" directive inside the "upstream" block,
now support IPv6 addresses.
*) Feature: the "resolver" directive now support IPv6 addresses and an
optional port specification.
*) Feature: the "least_conn" directive inside the "upstream" block.
*) Feature: it is now possible to specify a weight for servers while
using the "ip_hash" directive.
*) Bugfix: a segmentation fault might occur in a worker process if the
"image_filter" directive was used; the bug had appeared in 1.3.0.
*) Bugfix: nginx could not be built with ngx_cpp_test_module; the bug
had appeared in 1.1.12.
*) Bugfix: access to variables from SSI and embedded perl module might
not work after reconfiguration.
Thanks to Yichun Zhang.
*) Bugfix: in the ngx_http_xslt_filter_module.
Thanks to Kuramoto Eiji.
*) Bugfix: memory leak if $geoip_org variable was used.
Thanks to Denis F. Latypoff.
*) Bugfix: in the "proxy_cookie_domain" and "proxy_cookie_path"
directives.
