nginx 0.4.14
*) Feature: the "proxy_pass_error_message" directive in IMAP/POP3 proxy.
*) Feature: now configure detects system PCRE library on FreeBSD,
Linux, and NetBSD.
*) Bugfix: ngx_http_perl_module did not work with perl built with the
threads support; bug appeared in 0.3.38.
*) Bugfix: ngx_http_perl_module did not work if perl was called
recursively.
*) Bugfix: nginx ignored a host name in an request line.
*) Bugfix: a worker process may got caught in an endless loop, if a
FastCGI server sent too many data to the stderr.
*) Bugfix: the $upstream_response_time variable may be negative if the
system time was changed backward.
*) Bugfix: the "Auth-Login-Attempt" parameter was not sent to IMAP/POP3
proxy authentication server when POP3 was used.
*) Bugfix: a segmentation fault might occur if connect to IMAP/POP3
proxy authentication server failed.
