The changes mentioned below are only the user-facing ones. For a list of the complete set of changes, refer the changelog associated with the release tag.
Note
- The release-candidate pre-release was updated to a stable
v2.9.0tag. Going forward, release-candidate pre-releases will only be done for major releases. - The deprecated experimental VerticalPodAutoscaler metrics are no longer supported, and have been removed. We recommend to use CustomResourceState metrics to gather metrics from custom resources like the Vertical Pod Autoscaler.
- #2004 regulated label names to adhere with OTel-Prometheus standards, so existing label names that do not follow the same may be replaced by the ones that do. Please refer to the PR for more details.
