v2.8.0 / 2023-02-10

Note: The --version flag was removed as kube-state-metrics version also provides the same information. See #1956

Note: Experimental CustomResourceState changed their labels for better usability. See #1942
kube_crd_uptime{group="myteam.io", kind="Foo", version="v1"} -> kube_customresource_uptime{customresource_group="myteam.io", customresource_kind="Foo", customresource_version="v1"}

Full Changelog: v2.7.0...v2.8.0

v2.7.0 / 2022-11-25

v2.7.0 / 2022-11-25

Note: Experimental VerticalPodAutoscaler metrics are considered deprecated in this release and will be removed in v2.9.0.
Please use CustomResourceStateMetrics to gather metrics from VPA resources. See: #1718

Note: Experimental CustomResourceState changed their naming convention for better usability.
The name of the CRD used to be interpolated into the name of the metric which made it impossible to aggregate a CRD across different versions.
This was changed to have the GVK information represented as labels:
kube_myteam_io_v1_Foo_uptime -> kube_crd_uptime{group="myteam.io", kind="Foo", version="v1"}
