nginx 1.3.4 *) Change: the "ipv6only" parameter is now turned on by default for listening IPv6 sockets. *) Feature: the Clang compiler support. *) Bugfix: extra listening sockets might be created. Thanks to Roman Odaisky. *) Bugfix: nginx/Windows might hog CPU if a worker process failed to start. Thanks to Ricardo Villalobos Guevara. *) Bugfix: the "proxy_pass_header", "fastcgi_pass_header", "scgi_pass_header", "uwsgi_pass_header", "proxy_hide_header", "fastcgi_hide_header", "scgi_hide_header", and "uwsgi_hide_header" directives might be inherited incorrectly.
