we just upgraded InfluxDB from 1.7.3 to 1.7.6  (which will also give us Flux 0.24.0), Grafana from 5.4.3 to 5.4.4  and Mosquitto from 1.5.x to 1.6.1  all over the place. From the backend and data acquisition perspective, everything went smoothly. However, some dashboards already using Flux-Expressions are currently experiencing some teething problems.
We are sorry for any inconveniences this might cause for you.
With kind regards,
the people of Hiveeyes.
Please also recognize the background of this patch release for Grafana, which you might also want to apply to your systems.
