v1.20.1
🚨 Breaking or Notable Changes
Metrics and Tracing
In v1.19 we've dropped support for OpenCensus (which has been deprecated for a while) in favour of OpenTelemetry. This is a breaking change and details are documented here in the design document. and the website (https://knative.dev/docs/serving/observability/metrics/collecting-metrics/)
Secure Pod Defaults (#16042, @nader-ziada)
We've introduce secure-pod-defaults in an earlier release but this release includes a new setting AllowRootBounded that offers a better security posture for your workloads but balances the compatibility with images that require/expect you to run as root.
For v1.20 release the secure-pod-defaults default will remain disabled but in a future release (most likely v1.21) we will switch this default to AllowRootBounded.
If you're unsure whether your workloads will support this new setting you should explicitly set this option to disabled prior to upgrading to v1.21.
