nginx 1.0.3 *) Feature: the "auth_basic_user_file" directive supports "$apr1", "{PLAIN}", and "{SSHA}" password encryption methods. Thanks to Maxim Dounin. *) Feature: the "geoip_org" directive and $geoip_org variable. Thanks to Alexander Uskov, Arnaud Granal, and Denis F. Latypoff. *) Feature: ngx_http_geo_module and ngx_http_geoip_module support IPv4 addresses mapped to IPv6 addresses. *) Bugfix: a segmentation fault occurred in a worker process during testing IPv4 address mapped to IPv6 address, if access or deny rules were defined only for IPv6; the bug had appeared in 0.8.22. *) Bugfix: a cached reponse may be broken if proxy/fastcgi/scgi/ uwsgi_cache_bypass and proxy/fastcgi/scgi/uwsgi_no_cache directive values were different; the bug had appeared in 0.8.46.
