## Rails 5.0.0.beta4 (April 27, 2016) ##
|
|
|
|
* WebSocket protocol negotiation.
|
|
|
|
Introduces an Action Cable protocol version that moves independently
|
|
of and, hopefully, more slowly than Action Cable itself. Client sockets
|
|
negotiate a protocol with the Cable server using WebSockets' native
|
|
subprotocol support:
|
|
* https://tools.ietf.org/html/rfc6455#section-1.9
|
|
* https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols
|
|
|
|
If they can't negotiate a compatible protocol (usually due to upgrading
|
|
the Cable server with a browser still running old JavaScript) then the
|
|
client knows to disconnect, cease retrying, and tell the app that it hit
|
|
a protocol mismatch.
|
|
|
|
This allows us to evolve the Action Cable message format, handshaking,
|
|
pings, acknowledgements, and more without breaking older clients'
|
|
expectations of server behavior.

|
* Pubsub: automatic stream decoding.
|
|
|
|
stream_for @room, coder: ActiveSupport::JSON do |message|
|
|
# `message` is a Ruby hash here instead of a JSON string
|
|
|
|
The `coder` must respond to `#decode`. Defaults to `coder: nil`
|
|
which skips decoding entirely.

|
|
|
* Add ActiveSupport::Notifications to ActionCable::Channel.
|
|
|
|
*Matthew Wear*
|
|
|
|
* Safely support autoloading and class unloading, by preventing concurrent
|
|
loads, and disconnecting all cables during reload.
|
|
|
|
*Matthew Draper*
|
|
|
|
* Ensure ActionCable behaves correctly for non-string queue names.

## Rails 5.0.0.beta3 (February 24, 2016) ##
|
|
|
|
* Added `em_redis_connector` and `redis_connector` to
|
|
`ActionCable::SubscriptionAdapter::EventedRedis` and added `redis_connector`
|
|
to `ActionCable::SubscriptionAdapter::Redis`, so you can overwrite with your
|
|
own initializers. This is used when you want to use different-than-standard
|
|
Redis adapters, like for Makara distributed Redis.

## Rails 5.0.0.beta2 (February 01, 2016) ##
|
|
|
|
* Support PostgreSQL pubsub adapter.
|
|
|
|
*Jon Moss*
|
|
|
|
* Remove EventMachine dependency.
|
|
|
|
*Matthew Draper*
|
|
|
|
* Remove Celluloid dependency.
|
|
|
|
*Mike Perham*
|
|
|
|
* Create notion of an `ActionCable::SubscriptionAdapter`.
|
|
Separate out Redis functionality into
|
|
`ActionCable::SubscriptionAdapter::Redis`, and add a
|
|
PostgreSQL adapter as well. Configuration file for
|
|
ActionCable was changed from`config/redis/cable.yml` to
|
|
`config/cable.yml`.
