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.
