nginx 0.8.43 *) Feature: large geo ranges base loading speed-up. *) Bugfix: an error_page redirection to "location /zero { return 204; }" without changing status code kept the error body; the bug had appeared in 0.8.42. *) Bugfix: nginx might close IPv6 listen socket during reconfiguration. Thanks to Maxim Dounin. *) Bugfix: the $uid_set variable may be used at any request processing stage.
