+
+backport @effect/cluster from effect v4
+
+@effect/cluster no longer requires a Shard Manager, and instead relies on the
+`RunnerStorage` service to track runner state.
+
+To migrate, remove any Shard Manager deployments and use the updated layers in
+`@effect/platform-node` or `@effect/platform-bun`.
+
+# Breaking Changes
+
+- `ShardManager` module has been removed
+- `@effect/platform-node/NodeClusterSocketRunner` is now
+  `@effect/cluster/NodeClusterSocket`
+- `@effect/platform-node/NodeClusterHttpRunner` is now
+  `@effect/cluster/NodeClusterHttp`
+- `@effect/platform-bun/BunClusterSocketRunner` is now
+  `@effect/cluster/BunClusterSocket`
+- `@effect/platform-bun/BunClusterHttpRunner` is now
+  `@effect/cluster/BunClusterHttp`
+
+# New Features
+
+- `RunnerHealth.layerK8s` has been added, which uses the Kubernetes API to track
+  runner health and liveness. To use it, you will need a service account with
+  permissions to read pod information.
