May I ask what is the reasoning of language version 2.0 (apparently instead of 1.10) as introduced here? Is it a final decision? It seems to be related specifically to K2, but AFAIK it does not change the language significantly. I.e. there aren't differences that would justify distinction between Kotlin 1 and Kotlin 2, as it is in say python 2 vs python 3, right?

Please wait for an official announcement in 1.8.20-Beta blogpost

@mcpiroman A rewrite of the compiler front end is actually is very big and will lead to more kotlin features in the future. I wouldnt have expected such a major change to be in a incremental release
