A modern programming language that makes developers happier.

Heads up: Kotlin compiler plugins compiled with Kotlin 1.3 can’t be used in projects using Kotlin 1.4 M3 (M2 is fine). I filed a ticket and added a sample to reproduce the issue: <https://youtrack.jetbrains.com/issue/KT-40214>

It’s expected breaking change as I understand.
`1.4` has updated/changed plugin API.

I don’t see a breaking change in my plugin. But yes, seems to be the case.

Compiler plugins basically always break with new releases. They have no stability guarantees.

<@U33H6SB2B> I saw that and double checked: <https://youtrack.jetbrains.com/issues/KT?q=Tag:%20language-committee-approved%20Target%20versions:%201.4-M3,%201.4-M2,%201.4-M1,%201.4.0&amp;_ga=2.225808282.1002681388.1594512680-919897319.1560536387>

It make sense and I assume that’s also the reason they publish a new preview build for the serialization library. A word about compiler plugins in the compatibility section wouldn’t hurt.

Common problem - `1.3` binaries + `1.4` binaries = undefined behaviuor

In my cases `String.replace` and `Collection.add` don’t work as expected
