Hi, Any idea when ktor 3.0.0 is getting released or is there any interim version before 3.0.0 ?

The release date is unknown yet. You can try the EAP version of Ktor, e.g.

3.0.0-eap-826

.

Which features are you missing from 2.x that are in 3.x?

enable / disable HTTP2, i have already integrated it with 3.0.0-eap-757 , it works, but skeptical about taking it to production with the EAP, so knowing a tentative timeline of official 3.0.0 can help us to plan accordingly. or is it fine to go to production with EAP, our current production used version is 2.3.0.
