Upgrade notes
- Review the core and contrib changelogs for any breaking changes and run your integration tests against v0.156.0 artifacts before upgrading: https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.156.0 and https://github.com/open-telemetry/opentelemetry-collector-contrib/releases/tag/v0.156.0
- Pin images/tags in deployments and update Helm charts or operator manifests as needed. Roll out the new version in a canary or staged manner and, if you must roll back, redeploy the previously pinned tag.
