nginx 0.9.5
*) Change: now nginx uses a default listen backlog value -1 on
Linux.
Thanks to Andrei Nigmatulin.
*) Feature: the "utf8" parameter of "geoip_country" and "geoip_city"
directives.
Thanks to Denis F. Latypoff.
*) Bugfix: in a default "proxy_redirect" directive if "proxy_pass"
directive has no URI part.
Thanks to Maxim Dounin.
*) Bugfix: an "error_page" directive did not work with nonstandard
error codes; the bug had appeared in 0.8.53.
Thanks to Maxim Dounin.
