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.
