v0.9.0

Changes since v0.8.4

All official images for releases after v0.8.4 are available in k8s.gcr.io/prometheus-adapter/prometheus-adapter:$VERSION. The project also maintains a staging registry where images for each commit from the master branch are published. You can use this registry if you need to test a version from a specific commit, or if you need to deploy a patch while waiting for a new release, but do note that the stability of these images is not guaranteed.

Images for versions v0.8.4 and prior are only available in unofficial registries:

• https://quay.io/repository/coreos/k8s-prometheus-adapter-amd64
• https://hub.docker.com/r/directxman12/k8s-prometheus-adapter/
