Kotlin/kotlinx.serialization (org.jetbrains.kotlinx:kotlinx-serialization-json)

v1.7.3

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

This release aims to fix important issues that were discovered in the 1.7.2 release,
including the inability to sync certain projects into Android Studio/IntelliJ IDEA and exceptions from custom Uuid serializers.

It uses Kotlin 2.0.20 by default.

• Use explicit kotlin-stdlib and kotlin-test versions from version catalog (#​2818)
• Drop usage of deprecated Any?.freeze() in K/N target (#​2819)
• Check against serialName instead of simpleClassName (#​2802)
• Ignore NoClassDefFoundError when initializing builtins map for serializer() function (#​2803)
• Clarify example for SerializationException (#​2806)

v1.7.2

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

This release provides several new features, including a major Cbor configuration rework.
It uses Kotlin 2.0.20 by default.

Cbor feature set for COSE compliance

This change brings a lot of features to the CBOR format, namely:

• Serial Labels — see @CborLabel annotation and preferCborLabelsOverNames flag.
• Tagging of keys and values — see encode*Tags and verify*Tags set of flags
• Definite length encoding — see useDefiniteLengthEncoding. This flag affects object encoding, since decoding of arrays with definite lenghts is automatically supported.
• Option to globally prefer major type 2 for byte array encoding — see alwaysUseByteString flag.

Since there are quite a lot of flags now, they were restructured to a separate CborConfiguration class, similarly to JsonConfiguration.
It is possible to retrieve this configuration from CborEncoder/CborDecoder interfaces in your custom serializers (see their documentation for details).

All of these features make it possible to serialize and parse COSE-compliant CBOR, for example, ISO/IEC 18013-5:2021-compliant mobile driving license data.
In case you want to make use of them, there is a predefined Cbor.CoseCompliant instance.
However, some canonicalization steps (such as sorting keys) still need to be performed manually.

This functionality was contributed to us by Bernd Prünster.

Keeping generated serializers

One of the most requested features for serialization plugin was to continue to generate a serializer even if a custom one is specified for the class.
It allows using a plugin-generated serializer in a fallback or delegate strategy, accessing type structure via descriptor, using default serialization behavior in inheritors that do not use custom serializers.

Starting with this release, you can specify the @KeepGeneratedSerializer annotation on the class declaration to instruct the plugin to continue generating the serializer.
In this case, the serializer will be accessible using the .generatedSerializer() function on the class's companion object.

This annotation is currently experimental. Kotlin 2.0.20 or higher is required for this feature to work.

You can check out the examples in the documentation and in the PRs: #​2758, #​2669.

Serializer for kotlin.uuid.Uuid

Kotlin 2.0.20 added a common class to represent UUIDs in a multiplatform code.
kotlinx.serialization 1.7.2 provides a corresponding Uuid.serializer() for it, making it possible to use it in @Serializable classes.
Note that for now, serializer should be provided manually with @Contextual annotation.
Plugin will be able to automatically insert Uuid serializer in Kotlin 2.1.0.

See more details in the corresponding PR.

Other bugfixes and improvements

• Prohibited using of zero and negative field numbers in ProtoNumber (#​2766)
• Improve readability of protobuf decoding exception messages (#​2768) (thanks to xiaozhikang0916)
• docs(serializers): Fix grammatical errors (#​2779) (thanks to jamhour1g)
• Fixed VerifyError after ProGuard optimization (#​2728)
• Add wasm-wasi target to Okio integration (#​2727)

v1.7.1

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

This is a bugfix release that aims to fix missing kotlinx-serialization-hocon artifact.
It also contains experimental integration with kotlinx-io library.
Kotlin 2.0.0 is used by default.

Fixed HOCON publication

Sadly, 1.7.0 release was published incomplete: kotlinx-serialization-hocon artifact is missing from 1.7.0 and 1.7.0-RC releases.
This release fixes this problem and now kotlinx-serialization-hocon is available again with 1.7.1 version.
No other changes were made to this artifact. Related ticket: #​2717.

Add integration with a kotlinx-io library

kotlinx-io is an official multiplatform library that provides basic IO primitives, similar to Okio.
kotlinx.serialization integration is now available in a separate artifact, located at the kotlinx-serialization-json-io coordinates.
Integration artifact provides functions similar to existing Okio integration: encodeToSink, decodeFromSource, and decodeSourceToSequence.
Check out the PR for more details.

Other bugfixes

• Prohibited use of elements other than JsonObject in JsonTransformingSerializer with polymorphic serialization (#​2715)

v1.7.0

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

This release contains all of the changes from 1.7.0-RC and is compatible with Kotlin 2.0.
Please note that for reasons explained in the 1.7.0-RC changelog, it may not be possible to use it with the Kotlin 1.9.x
compiler plugin. Yet, it is still fully backwards compatible with previous versions.

The only difference with 1.7.0-RC is that classDiscriminatorMode property in JsonBuilder is marked as experimental,
as it should have been when it was introduced (#​2680).
