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.
