v1.6.3

==================

This release provides a couple of new features and uses Kotlin 1.9.22 as default.

Class discriminator output mode

Class discriminator provides information for serializing and deserializing polymorphic class hierarchies.
In case you want to encode more or less information for various third party APIs about types in the output, it is possible to control
addition of the class discriminator with the JsonBuilder.classDiscriminatorMode property.
For example, ClassDiscriminatorMode.NONE does not add class discriminator at all, in case the receiving party is not interested in Kotlin types.
You can learn more about this feature in the documentation and corresponding PR.

v1.6.2

v1.6.1

==================

This release uses Kotlin 1.9.20 by default, while upcoming 1.9.21 is also supported.

Trailing commas in Json

Trailing commas are one of the most popular non-spec Json variations.
A new configuration flag, allowTrailingComma, makes Json parser accept them instead of throwing an exception.
Note that it does not affect encoding, so kotlinx.serialization always produces Json without trailing commas.
See details in the corresponding PR

Support of WasmJs target

Kotlin/Wasm has been experimental for some time and gained enough maturity to be added to the kotlinx libraries.
Starting with 1.6.1, kotlinx.serialization provides a wasm-js flavor, so your projects with Kotlin/Wasm can have even more
functionality.
As usual, just add serialization dependencies to your build
and declare wasmJs target.
Please remember that Kotlin/Wasm is still experimental, so changes are expected.

Bugfixes and improvements

• Fix TaggedDecoder nullable decoding (#​2456) (thanks to Phillip Schichtel)
• Fix IllegalAccessException for some JPMS boundaries (#​2469)

v1.6.0

Kotlin 1.9.0 is used as a default, while 1.9.10 is also supported.
