+### Notice of Breaking Upgrade 10/17/2025
+
+Apache Openwhisk has migrated to the Apache Pekko framework. The master branch as of 10/17/2025 uses Apache Pekko. This change results in a breaking change such that you must re-deploy new clusters and cutover traffic to the new cluster. All other changes should be transient to you other than instead of using Akka configuration overrides in your deployments, you would now need to update those to use the Pekko equivalent. A 3.x release branch will eventually follow this
+change.
+
 ### Quick Start
 
 The easiest way to start using OpenWhisk is to install the "Standalone" OpenWhisk stack.

+The system can be configured to use Apache Pekko clustering to manage the distributed state of the Controller's load balancing algorithm.  This imposes the following constraints on a deployment
 
 ## Cluster setup
 
 To setup a cluster, the controllers need to be able to discover each other. There are 2 basic ways to achieve this:
 
-1. Provide the so called **seed-nodes** explicitly on deployment. Essentially you have a static list of possible seed nodes which are used to build a cluster. In an Ansible based deployment, they are determined for you from the `hosts` file. On any other deployment model, the `CONFIG_akka_cluster_seedNodes.$i` variables will need to be provided according to the [Akka cluster documentation](https://doc.akka.io/docs/akka/2.5/cluster-usage.html#joining-to-seed-nodes).
-2. Discover the nodes from an external service. This is built upon [akka-management](https://developer.lightbend.com/docs/akka-management/current/) and by default [Kubernetes](https://developer.lightbend.com/docs/akka-management/current/discovery.html#discovery-method-kubernetes-api) and [Mesos (Marathon)](https://developer.lightbend.com/docs/akka-management/current/discovery.html#discovery-method-marathon-api) are supported.

 ## Controller nodes must have static IPs/Port combination.
 
 It guarantees that failed nodes are able to join the cluster again.
-This limitation refers to the fact that Akka clustering doesn't allow to add new nodes when one of the existing members is unreachable (e.g. JVM failure). If each container receives a its ip and port dynamically upon the restart, in case of controller failure, it could come back online under a new ip/port combination which makes cluster consider it as a new member and it won't be added to the cluster (in certain cases it could join as a weeklyUp member).

 How to down the members.
 1. manually (sending an HTTP or JMX request to the controller). For this case an external supervisor for the cluster is required, which will down the nodes and provide an up-to-date list of seed nodes.
 2. automatically by setting the "auto-down-property" in controller that will allow the leader to down the node after a certain timeout. In order to mitigate brain split one could define a list of seed nodes which are reachable under static IPs or have static DNS entries.
