New Features

The v0.8.4 release contains the following major changes:

1. Support for Kubernetes Job brokers (#437). Now Akri has support for deploying Jobs to devices discovered by the Akri Agent. Previously, Akri only supported deploying Pods that were not intended to terminate (and would be restarted if they did). Adding Jobs enables more device use scenarios. More background can be found in the Jobs proposal. This is a breaking change as it required changes to Akri's Configuration CRD.
2. Fix to re-enable applying multiple Configurations that use the same Discovery Handler (#432). This adds back functionality that was removed in v0.6.5 when enabling Akri's new extensibility model.
3. Akri depends on crictl to track whether Pods deployed by the Akri Controller are still running. This release adds new functionality (#418) such that crictl is pre-installed in the Agent container so that it does not need to be installed on each node.

Fixes, features, and optimizations

• fix: Make debug echo capacity configurable (#419)
• fix: Return okay if get 404 when trying to delete an Instance (#420)
• opt: Update .NET dependencies, removing vulnerabilities and reducing size (#422)
