 ### Release Notes
 
+- On systemd Telegraf will no longer redirect it's stdout to /var/log/telegraf/telegraf.log.
+On most systems, the logs will be directed to the systemd journal and can be
+accessed by `journalctl -u telegraf.service`. Consult the systemd journal
+documentation for configuring journald. There is also a [`logfile` config option](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf#L70)
+available in 1.1, which will allow users to easily configure telegraf to
+continue sending logs to /var/log/telegraf/telegraf.log.
