nginx 0.5.35 *) Change: now the ngx_http_userid_module adds start time microseconds to the cookie field contains a pid value. *) Change: now the uname(2) is used on Linux instead of procfs. Thanks to Ilya Novikov. *) Feature: the "If-Range" request header line support. Thanks to Alexander V. Inyukhin. *) Bugfix: in HTTPS mode requests might fail with the "bad write retry" error; bug appeared in 0.5.13. *) Bugfix: the STARTTLS in SMTP mode did not work. Thanks to Oleg Motienko. *) Bugfix: large_client_header_buffers did not freed before going to keep-alive state. Thanks to Olexander Shtepa. *) Bugfix: the "limit_rate" directive did not allow to use full throughput, even if limit value was very high. *) Bugfix: the $status variable was equal to 0 if a proxied server returned response in HTTP/0.9 version. *) Bugfix: if the "?" character was in a "error_page" directive, then it was escaped in a proxied request; bug appeared in 0.5.32.
