Release notes

0.20.0 release is focused on giving a library its final and stable API shape.

We have carefully evaluated every public declaration and decided whether it should be publicly available. As a result, some declarations were deprecated with an intention of removing them from public API because they are going to be replaced with others, more valuable and useful for users.

Deprecated symbols include:

• Pre-defined JSON instances like nonStrict — strictMode was split to 3 separate, more granular, flags. Users are encouraged to create their own configuration;
• Top-level serializers like IntSerializer and ArrayListSerializer. They were replaced with constructor-like factory functions.
• SerialClassDescImpl creation class replaced with SerialDescriptor builder function to ease writing of custom serializers and maintain SerialDescriptor contract.
• Internal utilities, like HexConverter and ByteBuffer, were deprecated as not relevant to serialization public API.
• Add-on formats like Protobuf, CBOR and Properties (formerly Mapper) are now extracted to separate artifacts to keep the core API lightweight.

We have spent a lot of effort into the quality, documenting most of the core interfaces, establishing their contracts, fixing numerous of bugs, and even introducing new features that may be useful for those of you who write custom serializers — see JsonTransformingSerializer.

Such API changes, of course, may be not backwards-compatible in some places, in particular, between compiler plugin and runtime. Given that the library is still is in the experimental phase, we took the liberty to introduce breaking changes in order to give users the better, more convenient API. Therefore, this release has number 0.20.0 instead of 0.15.0; Kotlin 1.3.70 is compatible only with this release.

To migrate:

1. Replace import kotlinx.serialization.internal.* with import kotlinx.serialization.builtins.*. This action is sufficient for most of the cases, except primitive serializers — instead of using IntSerializer, use Int.serializer(). For other object-like declarations, you may need to transform it to function call: ByteArraySerializer => ByteArraySerializer().

2. Pay attention to the changed JsonConfiguration constructor arguments: instead of strictMode, now three different flags are available: ignoreUnknownKeys, isLenient, and serializeSpecialFloatingPointValues.

3. If you used formats other than JSON, make sure you've included the corresponding artifact as dependency, because now they're located outside of core module. See formats list for particular artifact coordinates.

4. Other corresponding deprecation replacements are available via standard @Deprecated(replaceWith=..) mechanism. (use Alt+Enter for quickfix replacing).
