nginx 0.5.32 *) Change: now nginx tries to set the "worker_priority", "worker_rlimit_nofile", "worker_rlimit_core", and "worker_rlimit_sigpending" without super-user privileges. *) Change: now nginx escapes space and "%" in request to a mail proxy authentication server. *) Change: now nginx escapes "%" in $memcached_key variable. *) Change: the special make target "upgrade1" was defined for online upgrade of 0.1.x versions. *) Feature: the "add_header Last-Modified ..." directive changes the "Last-Modified" response header line. *) Feature: the mail proxy supports AUTHENTICATE in IMAP mode. Thanks to Maxim Dounin. *) Feature: the mail proxy supports STARTTLS in SMTP mode. Thanks to Maxim Dounin. *) Bugfix: nginx did not close directory file on HEAD request if autoindex was used. Thanks to Arkadiusz Patyk. *) Bugfix: the "proxy_hide_header" and "fastcgi_hide_header" directives did not hide response header lines whose name was longer than 32 characters. Thanks to Manlio Perillo. *) Bugfix: active connection counter always increased if mail proxy was used. *) Bugfix: if backend returned response header only using non-buffered proxy, then nginx closed backend connection on timeout. *) Bugfix: nginx did not support several "Connection" request header lines. *) Bugfix: a charset set by the "charset" directive was not appended to the "Content-Type" header set by $r->send_http_header(). *) Bugfix: a segmentation fault might occur in worker process if /dev/poll method was used. *) Bugfix: nginx did not work on FreeBSD/sparc64. *) Bugfix: a segmentation fault occurred in worker process if invalid address was set in the "auth_http" directive. *) Bugfix: now nginx uses default listen backlog value 511 on all platforms except FreeBSD. Thanks to Jiang Hong. *) Bugfix: now Solaris sendfilev() is not used to transfer the client request body to FastCGI-server via the unix domain socket. *) Bugfix: if the same host without specified port was used as backend for HTTP and HTTPS, then nginx used only one port - 80 or 443. *) Bugfix: the "proxy_ignore_client_abort" and "fastcgi_ignore_client_abort" directives did not work; bug appeared in 0.5.13.
