Up to date docker container image?

I just installed emoncms in docker (because redis/ubuntu etc) but I notice that the UI around the HeatPump app was a little different (no instantaneous COP for example). I see that the bottom of the page announces

Powered by OpenEnergyMonitor.org 11.3.24

which makes me wonder if the docker image is a little stale?

Is there a way to get a more up to date one anywhere? Or to update one? On the whole, the docker solution is looking good for me, especially now I’ve tweaked it to bind mount rather than hide everything away in volumes. Makes backup/restore much more straightforward.

Thanks
