Knative Eventing release v0.21.1

Required Actions

• BREAKING CHANGE: PingSource binary mode now sends the actual binary data in event body instead of base64-encoded form. (#4851, @eclipselu)
• You need to run the storage migration tool after the upgrade to migrate from v1beta1 to v1beta2 pingsources.sources.knative.dev resources. (#4750, @eclipselu)

Enhancement

• 🎁 Adding HorizontalPodAutoscaler and PodDisruptionBudget for the eventing webhook (#4792, @matzew)
• 🎁 Add event reply header contract to the spec (#4560, @zhongduo)
• 🎁 Cloudevent traces available for PingSource (#4877, @Shashankft9)
• 🎁 CloudEvents send to dead-letter endpoints include extension attribute called ce-knativedispatcherr which contains encoded HTTP Response error information from final dispatch attempt. (#4760, @travis-minke-sap)
• 🎁 Message receiver supports customized liveness and readiness check (#4730, @grac3gao)
• 🎁 The imc-dispatcher service adds new trace span attributes to be consistent with broker-ingress.knative-eventing & broker-filter.knative-eventing services. The new attributes are messaging.destination, messaging.message_id, messaging.protocol and messaging.system (#4659, @xtreme-sameer-vohra)

API Change

• 🎁 Add Trigger.Delivery field which allows configuration of Delivery per Trigger. (#4654, @slinkydeveloper)

Bug or Regression

• Fix availability of zipkin traces for APIServerSource (#4842, @Shashankft9)
• 🐛 Fix bug where sometimes the pods were not deemed up during setup. #4725 (#4741, @vaikas)
• 🐛 Fix bug where v1beta1 would allow mutations to immutable fields. v1beta1 trigger.spec.broker is immutable. (#4843, @vaikas)

Clean up

• 🗑️ Now the config-imc-event-dispatcher values are not configurable on-fly anymore, that is, if you need to configure such values, you need to redeploy the dispatcher deployment (#4543, @slinkydeveloper)
• 🗑️ PingSource: remove special handling of JSON data since events are always sent in binary mode. (#4858, @lionelvillard)
• 🗑️ Cleanup channel duck types internals (#4749, @slinkydeveloper)

  • You must run pre-install job prior to upgrading to get pingsource resources to v1beta2 API. (#3951, @aavarghese)
• Change storage versions of eventing.- resources from v1beta1 to v1:
  • “brokers.eventing.knative.dev”

  • “Parallels.flows.knative.dev”
  • “Sequences.flows.knative.dev”
  • You must run pre-install job prior to upgrading to get flows.- resources to v1 API. (#3924, @aliok)

New Features

• Allow MTChannelBroker TTL to be configured via ENV variable. (#3962, @vaikas)
• PingSource adapter now uses bucket-based leader election (#4009, @lionelvillard)
• PingSource adapter deployment can now be customized at installation time (#3987, @lionelvillard)

Bug Fixes

• The default exponential backoff duration now matches the advertised algorithm in the DeliverySpec.BackoffDelay comments. User action required to evaluate if DeliverySpec.BackoffDelay settings in Subscription.spec.delivery remain appropriate. (#4115, @travis-minke-sap)
• Channels and Brokers correctly retry on non 2xx HTTP status codes (#4112, @pierDipi)
• Make pingsource adapter controller read-only (#4099, @lionelvillard)
• If you create a Parallel, then later add branches to it, caused a panic. (#3946, @vaikas)
• In cases where Filter sends a message and it fails or response is nil, it will panic because it uses it. (#3897, @vaikas)
• Tests sometimes flake when the webhook fails. (#3906, @vaikas)

• Update the spec to include v1 of the channelable. (#3870, @vaikas)

• Fix bug which could cause Trigger Dependency flakiness because we were incorrectly setting up the informer tracking the dependent sources. (4294, @vaikas). (4296, @vaikas)
