Announcing Knative v1.19 Release¶

Note

We've discovered severe issues with the OpenTelemetry Prometheus Exporter (see: https://github.com/knative/pkg/issues/3224). We advise users to hold off upgrading until we have new patch releases out.

A new version of Knative is now available across multiple components.

Follow the instructions in Installing Knative to install the components you require.

Highlights¶

This release's core components brings some notable changes.

Serving supports new K8s "image" volume type.
Eventing now uses OTel to report it's metrics across multiple components instead of Zipkin/OpenCensus and other features or improvements.
Functions run command now supports --address specification, adds multiple automation possibilities with new ENV variables or flags and your function can now be invoked via GET requests and some additional bug fixes and smaller improvements.
