nginx 0.8.50 *) Feature: the "secure_link", "secure_link_md5", and "secure_link_expires" directives of the ngx_http_secure_link_module. *) Feature: the -q switch. Thanks to Gena Makhomed. *) Bugfix: worker processes may got caught in an endless loop during reconfiguration, if a caching was used; the bug had appeared in 0.8.48. *) Bugfix: in the "gzip_disable" directive. Thanks to Derrick Petzold. *) Bugfix: nginx/Windows could not send stop, quit, reopen, and reload signals to a process run in other session.
