nginx 0.8.16
*) Feature: the "image_filter_transparency" directive.
*) Bugfix: "addition_types" directive was incorrectly named
"addtion_types".
*) Bugfix: resolver cache poisoning.
Thanks to Matthew Dempsky.
*) Bugfix: memory leak in resolver.
Thanks to Matthew Dempsky.
*) Bugfix: invalid request line in $request variable was written in
access_log only if error_log was set to "info" or "debug" level.
*) Bugfix: in PNG alpha-channel support in the
ngx_http_image_filter_module.
*) Bugfix: nginx always added "Vary: Accept-Encoding" response header
line, if both "gzip_static" and "gzip_vary" were on.
*) Bugfix: in UTF-8 encoding support by "try_files" directive in
nginx/Windows.
*) Bugfix: in "post_action" directive usage; the bug had appeared in
0.8.11.
