nginx 0.3.18
*) Feature: the "server_names" directive supports the ".domain.tld"
names.
*) Feature: the "server_names" directive uses the hash for the
"*.domain.tld" names and more effective hash for usual names.
*) Change: the "server_names_hash_max_size" and
"server_names_hash_bucket_size" directives.
*) Change: the "server_names_hash" and "server_names_hash_threshold"
directives were canceled.
*) Feature: the "valid_referers" directive uses the hash site names.
*) Change: now the "valid_referers" directive checks the site names
only without the URI part.
*) Bugfix: some ".domain.tld" names incorrectly processed by the
ngx_http_map_module.
*) Bugfix: segmentation fault was occurred if configuration file did
not exist; bug appeared in 0.3.12.
*) Bugfix: on 64-bit platforms segmentation fault may occurred on
start; bug appeared in 0.3.16.
