We've updated the interface a bit, so I'd like to announce the update.
We'll keep QuicTransport for a while, to make the migration easier.
We didn't apply the change for methods on QuicTransport.
You can see the newest IDL definition (in Chromium implementation) here
Please note that the API is not at all final, and we will make further changes. But we'll do our best to minimize your pain when we update the API.
