Due to the sunset of [Google Conversational Actions](https://developers.google.com/assistant/ca-sunset) on June 13, 2023, the Google Actions Endpoint is deprecated. The full removal of the Endpoint is planned for a near-future Cognigy.AI release. After removal, the Endpoint will no longer be available.

We developed a [version compatibility matrix](https://docs.cognigy.com/release-notes/4.56/#infrastructure) for the Cognigy products. This matrix outlines the compatibility of Cognigy product versions with Cognigy infrastructure components, such as Kubernetes, MongoDB, and Redis.
