Changes with nginx 1.5.4 27 Aug 2013 *) Change: the "js" extension MIME type has been changed to "application/javascript"; default value of the "charset_types" directive was changed accordingly. *) Change: now the "image_filter" directive with the "size" parameter returns responses with the "application/json" MIME type. *) Feature: the ngx_http_auth_request_module. *) Bugfix: a segmentation fault might occur on start or during reconfiguration if the "try_files" directive was used with an empty parameter. *) Bugfix: memory leak if relative paths were specified using variables in the "root" or "auth_basic_user_file" directives. *) Bugfix: the "valid_referers" directive incorrectly executed regular expressions if a "Referer" header started with "https://". Thanks to Liangbin Li. *) Bugfix: responses might hang if subrequests were used and an SSL handshake error happened during subrequest processing. Thanks to Aviram Cohen. *) Bugfix: in the ngx_http_autoindex_module. *) Bugfix: in the ngx_http_spdy_module. -- Maxim Dounin http://nginx.org/en/donation.html
