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.
