🚨 Note: Please skip this release and use v1.7.1 release. 🚨

We discovered a bug that prevents upgrades if you configured revision-timeout-seconds in the ConfigMap config-defaults to be less than 300. This was fixed in the subsequent point release.

Changes

Notable

Prior RevisionSpec.TimeoutSeconds would cause a request to timeout if the user container returned no response in the allotted time. This would allow for apps to return some data and then remain open forever indefinitely. This prior behaviour was not conformant to the Knative Serving API specification.

In this release we've fixed this behaviour and provided additional knobs to allow users greater control of various timings.

• Revision timeouts now has three knobs for users to control (#12970, @nader-ziada)
  • TimeoutSeconds represents the max duration a request can take
  • ResponseStartTimeoutSeconds is the timeout allowed before a request starts responding
  • IdleTimeoutSeconds is the max duration a request can remain open without getting any data.

💫 New Features & Changes

• Adds a autoscaling.knative.dev/activation-scale annotation that allows the user to set a minimum number of replicas when not scaled to zero. Note that the initial target scale for a revision is still handled by initial-scale; activation-scale will only apply on subsequent scales from zero. (#13161, @psschwei)

🐞Bug Fixes

• Readiness probes no longer fail if the user container is restarted (due to a liveness probe failure) (#13229, @dprotaso)

🧹 Cleanup

• Building Knative Serving requires go v1.18 (#13169, @psschwei)
• Build commit SHA is no longer under kodata in our containers it is now embedded in the binary since we build with go1.18. Use go version -m [binary] to get the same information (#13130, @dprotaso)
