nginx 1.1.7 *) Feature: support of several resolvers in the "resolver" directive. Thanks to Kirill A. Korinskiy. *) Bugfix: a segmentation fault occurred on start or while reconfiguration if the "ssl" directive was used at http level and there was no "ssl_certificate" defined. *) Bugfix: reduced memory consumption while proxying of big files if they were buffered to disk. *) Bugfix: a segmentation fault might occur in a worker process if "proxy_http_version 1.1" directive was used. *) Bugfix: in the "expires @time" directive.
