HTTP2 early hints support for Rails

Early Hints is a new HTTP status code that allows your application to send links to assets that you would like to load early. The spec is still in draft but Rails is ready to support it along with Puma. Check this blog post to know more about this feature.

Friendly error message when unsubscribing from non-existent Action Cable subscription

If for some reason the frontend code tries to unsubscribe from a non existing Action Cable subscription, then a friendly error message will be displayed:

Unable to find subscription with identifier: {“channel”:”SomeChannel”}.

Earlier, it used to show:

NoMethodError - undefined method `unsubscribe_from_channel’ for nil:NilClass
