Ever wondered how to stabilize quite a rewritten compiler of an already stable programming language? This talk will cover the K2 stabilization cycle: what were the steps taken, some facts, numbers and a bit of plans, with a sprinkle of tasks we had to deal with on our way. Svetlana Isakova’s talk about the new K2 compiler: https://www.youtube.com/watch?v=iTdJJq_LyoY. Check out what’s new in the latest compiler preview and how to update to it: https://kotlinlang.org/docs/whatsnew-eap.html.
