Changes with nginx 0.5.32 24 Sep 2007

    *) 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.

       Thanks to Maxim Dounin.

       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.
