nginx 0.6.30 *) Change: now if an "include" directive pattern does not match any file, then nginx does not issue an error. *) Feature: now the time in directives may be specified without spaces, for example, "1h50m". *) Bugfix: memory leaks if the "ssl_verify_client" directive was on. Thanks to Chavelle Vincent. *) Bugfix: the "sub_filter" directive might set text to change into output. *) Bugfix: the "error_page" directive did not take into account arguments in redirected URI. *) Bugfix: now nginx always opens files in binary mode under Cygwin. *) Bugfix: nginx could not be built on OpenBSD; bug appeared in 0.6.15.
