Can you share some details why you need this?

Hi @jonathanpeppers!! • Im using Kotlinx Serialization 1.8.1 in my KMM SDK. • My .NET MAUI project is referencing the NuGet package https://www.nuget.org/packages/Xamarin.KotlinX.Serialization.Core, which is version 1.7.3. • The ABI (binary interface) between these versions is not guaranteed to be compatible, especially between minor versions (1.7.x → 1.8.x). Refer https://github.com/Kotlin/kotlinx.serialization/issues/2968

I would appreciate it if you could help to upgrade to version 1.8.1.
