## UNRELEASED

FEATURES:
* Connect: Support Kubernetes health probe synchronization with Consul for connect injected pods. [[GH-363](https://github.com/hashicorp/consul-k8s/pull/363)]
* Adds a new controller to the connect-inject webhook which is responsible for synchronizing Kubernetes pod health checks with Consul service instance health checks.
A Consul health check is registered for each connect-injected pod which mirrors the pod's Readiness status to Consul. This modifies connect routing to only
pods which have passing Kubernetes health checks. See breaking changes for more information.
* Adds a new label to connect-injected pods which mirror the `consul.hashicorp.com/connect-inject-status` annotation.

Consul-ENT only: Adds a new annotation to connect-injected pods when namespaces are enabled: `consul.hashicorp.com/consul-namespace` [[GH-376](https://github.com/hashicorp/consul-k8s/pull/376)]

BREAKING CHANGES:
* Connect: With the addition of the connect-inject health checks controller any connect services which have failing Kubernetes readiness
probes will no longer be routable through connect until their Kubernetes health probes are passing.
Previously, if any connect services were failing their Kubernetes readiness checks they were still routable through connect.
Users should verify that their connect services are passing Kubernetes readiness probes prior to using health checks synchronization.

DEPRECATIONS:
* `create-inject-token` in the server-acl-init job has been undeprecated.
