## v2.10.0 / 2023-08-31

### Note
- Label and annotation metrics aren't exposed by default anymore to reduce the memory usage of the default configuration of kube-state-metrics. Before this change, they used to only include the name and namespace of the objects which is not relevant to users not opting in these metrics.
