Hello there, I update my kotlin version to 1.4.0 ...

# serialization

[Nicolas Bourdin]

Hello there, 
I update my kotlin version to 1.4.0 and followed the migration guide for the kotlin serialization plugin (https://github.com/Kotlin/kotlinx.serialization/blob/1.0.0-RC/docs/migration.md)

But when I launch my app I got the following error in runtime on a « @Serializable » class
Your current kotlinx.serialization core version is too low, while current Kotlin compiler plugin 1.4.0 requires at least 1.0-M1-SNAPSHOT. Please update your kotlinx.serialization runtime dependency.

Any idea please ? Thanks in advance
