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.
