New release of GraphQL Subscriptions for Javascript

The Apollo team has released new versions of their GraphQL subscriptions implementation, which includes significant improvements and additions. The releases include a new RFC to add GraphQL subscriptions to the spec, and the team has been working hard to get to this exciting place. The new releases focus on improving the subscription architecture, adding more lifecycle events for both clients and servers, and introducing a new INIT transport message that allows developers to pass custom arguments from the client to the server. Additionally, the team has refactored their code, made the API more flexible, and added support for MQTT and Redis protocols. The goal is to create a flexible implementation while keeping app-specific code easier, and the team plans to continue improving GraphQL subscriptions with new features and documentation.
