       connections might be too aggressive.
       Thanks to Joel Cunningham.

       "sendfile" directive on FreeBSD and macOS; the bug had appeared in
       1.7.8.

       infinite time when using HTTP/2.

    *) Bugfix: in the ngx_http_mp4_module.

    *) Bugfix: "ignore long locked inactive cache entry" alerts might appear
       in logs when proxying WebSocket connections with caching enabled.

       support is configured automatically.
