CHANGELOG.md

v2.8.1 / 2023-02-22

• [BUGFIX] Fix public Builder compatibility with BuilderInterface @clamoriniere #1994

v2.8.0 / 2023-02-10

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"}

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"} See: #1847
