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.
