 In Kubernetes 1.14 there was a major [metrics overhaul](https://github.com/kubernetes/enhancements/issues/1206) implemented. Therefore v0.1.x of this repository is the last release to support Kubernetes 1.13 and previous version on a best effort basis.
 
 Some alerts now use Prometheus filters made available in Prometheus 2.11.0, which makes this version of Prometheus a dependency.
 
+With Prometheus v3, [histograms are normalized](https://prometheus.io/docs/prometheus/latest/migration/#le-and-quantile-label-values)
+This breaks some of the recording rules that select on the `le` label.

 Warning: This compatibility matrix was initially created based on experience, we do not guarantee the compatibility, it may be updated based on new learnings.
 
 Warning: By default the expressions will generate *grafana 7.2+* compatible rules using the *$__rate_interval* variable for rate functions. If you need backward compatible rules please set *grafana72: false* in your *_config*
