nginx 0.7.60 *) Feature: the "updating" parameter in "proxy_cache_use_stale" and "fastcgi_cache_use_stale" directives. *) Feature: the "keepalive_requests" directive. *) Bugfix: in open_file_cache and proxy/fastcgi cache interaction on start up. *) Bugfix: open_file_cache might cache open file descriptors too long. *) Bugfix: the "If-Modified-Since", "If-Range", etc. client request header lines were passed to backend while caching if no "proxy_set_header" directive was used with any parameters. *) Bugfix: the "Set-Cookie" and "P3P" response header lines were not hidden while caching if no "proxy_hide_header/fastcgi_hide_header" directives were used with any parameters. *) Bugfix: the ngx_http_image_filter_module did not support GIF87a format. Thanks to Denis Ilyinyh. *) Bugfix: nginx could not be built modules on Solaris 10 and early; the bug had appeared in 0.7.56. *) Bugfix: XLST filter did not work in subrequests. *) Bugfix: in relative paths handling in nginx/Windows. *) Bugfix: in proxy_store, fastcgi_store, proxy_cache, and fastcgi_cache in nginx/Windows.
