10/07/2024, 7:32 AMThe article looks dubious. None of the mentioned changes are 2.0 specific. Context receivers were introduced as experimental a while ago. The type inference example works in 1.9 and kotlinx.coroutines is a library that has its own release schedule.

10/07/2024, 11:28 AMThere aren't that many type inference differences between K1 and K2. But generally, anything that's redundant (redundant type argument, redundant cast after smart cast) will be marked by the IDE with an inspection. You will need to use K2 Mode. This will however mark all the stuff, not just stuff that's new with K2. So if your code base was free of inspection warnings before the switch, you can just run "Analyze code" and will see everything that's become obsolete.

Then you don't need to do anything. When you are in K2 mode, and you commit, IntelliJ will remove everything that was necessary beforehand but that K2 is now able to infer itself.
