If you upgrade to v1.26 please be aware of the additional features for adding Tags to Trigger and Host to add additional graphs and the associated `html.template` updates that come alone with it (otherwise the new graphs will not show ...).
### v1.25 and higher
Template data provisioning and code has fundamentally changed. If you upgrade from an earlier version as v1.25, make sure you understand the changes in templates/html.template (now making use of arrays for lists of items).
