@abernix Any chance this can be merged and released?

Hi @NeoPhi @baconz - we're ready to get this merged, but I just noticed you've released a newer 0.9.9 version of subscriptions-transport-ws. Did you want to update to the newer version first?

[baconz]

@hwillson makes sense, I bumped to 0.9.9!

Thanks @baconz - merging now (and we'll make sure these changes get added to the upcoming Apollo Server 2.0 version).
