nginx 0.5.6 *) Change: now the ngx_http_index_module ignores all methods except the GET, HEAD, and POST methods. *) Feature: the ngx_http_limit_zone_module. *) Feature: the $binary_remote_addr variable. *) Feature: the "ssl_session_cache" directives of the ngx_http_ssl_module and ngx_imap_ssl_module. *) Feature: the DELETE method supports recursive removal. *) Bugfix: the byte-ranges were transferred incorrectly if the $r->sendfile() was used.
