Hey @hhariri! Are there any links for breaking changes/how to migrate from 2.x?

[hhariri]

It should be on the site IIRC. We normally have this in the change log.

Hi, I see there is also a new Ktor plugin version: https://plugins.jetbrains.com/plugin/16008-ktor/versions/stable
Does this plugin upgrade enable turning on K2 mode in IntelliJ?

[Aleksei Tirman [JB]]

This version of the Ktor plugin supports the K2 mode in IntelliJ IDEA
