See migration guide: <https://ktor.io/quickstart/migration/1.3.0.html>

Known issues:
• Netty HTTP/2 push sometimes get broken
• Running ios and native client engine on non-main worker is still not supported (there are only few working scenarios so not guaranteed to work)

We just no longer need `setMapper` , even on native?

There is no need to register types anymore

Found a small typo: migration guide says "Published 14 Jan *202* (`1.3.0`)" :slightly_smiling_face:
