2.0.0
Checkmk's Grafana connector underwent a complete rewrite in this release. It requires Grafana >= 8.0.0 and Checkmk > 2.1.0
(It is possible to query data from Checkmk >= 2.0.0p20, but host and service dropdowns are not constrained by other active filters and single metric graphs do not work with Checkmk Raw Edition).
An update script is available to migrate the configuration from the previous connector to this new one, see README.md on how to use it. However, there are some backwards incompatible changes and not all features are conserved.
