Release Notes

Kotlin/kotlinx.serialization

v1.3.2

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

This release contains several features and bugfixes for core API as well as for HOCON format.
It uses Kotlin 1.6.10 by default.

Serializing objects to HOCON

It's now possible to encode Kotlin objects to Config values with new Hocon.encodeToConfig function.
This feature may help edit existing configs inside Kotlin program or generate new ones.

Big thanks to Osip Fatkullin for implementing this.

Polymorphic default serializers

As of now, polymorphicDefault clause inside SerializersModule { } builder specifies a
fallback serializer to be used only during deserialization process. A new function has been introduced to allow setting
fallback serializer for serialization: polymorphicDefaultSerializer.
This function should ease serializing vast hierarchies of third-party or Java classes.

Note that there are two new experimental functions, polymorphicDefaultSerializer and polymorphicDefaultDeserializer.
To avoid naming confusion, we are going to deprecate polymorphicDefault in favor of polymorphicDefaultDeserializer in the next minor release (1.4.0).

Credit for the PR goes to our contributor Joseph Burton.
