nginx 0.8.48 *) Change: now the "server_name" directive default value is an empty name "". Thanks to Gena Makhomed. *) Change: now the "server_name_in_redirect" directive default value is "off". *) Feature: the $geoip_dma_code, $geoip_area_code, and $geoip_region_name variables. Thanks to Christine McGonagle. *) Bugfix: the "proxy_pass", "fastcgi_pass", "uwsgi_pass", and "scgi_pass" directives were not inherited inside "limit_except" blocks. *) Bugfix: the "proxy_cache_min_uses", "fastcgi_cache_min_uses" "uwsgi_cache_min_uses", and "scgi_cache_min_uses" directives did not work; the bug had appeared in 0.8.46. *) Bugfix: the "fastcgi_split_path_info" directive used incorrectly captures, if only parts of an URI were captured. Thanks to Yuriy Taraday and Frank Enderle. *) Bugfix: the "rewrite" directive did not escape a ";" character during copying from URI to query string. Thanks to Daisuke Murase. *) Bugfix: the ngx_http_image_filter_module closed a connection, if an image was larger than "image_filter_buffer" size.
