Upgrade notes

• On upgrade from 0.2.0 there will be <10 seconds of unavailability for all in-memory channels. During this time all messages sent to in-memory channels will be lost. The in-memory channel has no durability or reliability guarantees and should only be used for testing or ephemeral messaging.

Eventing core

• Subscriptions may only subscribe to Channels in the same namespace.
• Subscriptions can be deleted after their subscribed Channel is deleted.
• Channels without a specified provisioner will have a default provisioner applied. The default provisioner is specified in the knative-eventing/default-channel-webhook ConfigMap and defaults to in-memory-channel.
• The ClusterChannelProvisioner is now part of the provisioner CRD category.

In-memory channel

• In-memory channel is now the default for Channels that don't specify a provisioner.
• Renamed channel dispatcher k8s service from in-memory-channel-clusterbus.svc.cluster.local to in-memory-channel-dispatcher.svc.cluster.local.
