nginx 0.8.1 *) Feature: the "updating" parameter in "proxy_cache_use_stale" and "fastcgi_cache_use_stale" directives. *) 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.
