nginx 0.8.18 *) Feature: the "read_ahead" directive. *) Feature: now several "perl_modules" directive may be used. *) Feature: the "limit_req_log_level" and "limit_conn_log_level" directives. *) Bugfix: now "limit_req" directive conforms to the leaky bucket algorithm. Thanks to Maxim Dounin. *) Bugfix: nginx did not work on Linux/sparc. Thanks to Marcus Ramberg. *) Bugfix: nginx sent '\0' in a "Location" response header line on MKCOL request. Thanks to Xie Zhenye. *) Bugfix: zero status code was logged instead of 499 status code; the bug had appeared in 0.8.11. *) Bugfix: socket leak; the bug had appeared in 0.8.11.
