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.
