Important Changes

• KSErrorType.toString() now contains the reference name it was tried to be resolved, and therefore KSErrorType is no longer a singleton. Processors relying on equality checks of that (in contrast of using KSType.isError) will need to be updated accordingly.

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

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).

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.

Other features

• Add kebab-case naming strategy (#​2531) (thanks to Emil Kantis)
• Add value class support to the ProtoBufSchemaGenerator (#​2542) (thanks to Felipe Rotilho)

Bugfixes and improvements

• Fix: Hocon polymorphic serialization in containers (#​2151) (thanks to LichtHund)
• Actualize lenient mode documentation (#​2568)
• Slightly improve error messages thrown from serializer() function (#​2533)
• Do not try to coerce input values for properties (#​2530)
• Make empty objects and arrays collapsed in pretty print mode (#​2506)
• Update Gradle dokka configuration to make sure "source" button is visible in all API docs (#​2518, #​2524)

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)
• Cbor: check if inline value classes are marked as @​ByteString (#​2466) (thanks to eater)
• Improve polymorphic deserialization optimization (#​2481)
• Update Okio dependency to 3.6.0 (#​2473)
• Add protobuf conformance tests (#​2404) (thanks to Doğaç Eldenk)
• Support decoding maps with boolean keys (#​2440)

v1.6.0

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

This release contains all features and bugfixes from 1.6.0-RC plus some bugfixes on its own (see below).
Kotlin 1.9.0 is used as a default, while 1.9.10 is also supported.

Bugfixes

• Improve error messages from Json parser (#​2406)
• Mark @​SerialName, @​Required and @​Transient with @​MustBeDocumented (#​2407)
• Ensure that no additional files except java compiler output get into multi-release jar (#​2405)
• Fix enums with negative numbers in protobuf not serializing & de-serializing (#​2400) (thanks to Doğaç Eldenk)

v1.5.1

==================
This release contains an important Native targets overhaul, as well as numerous enhancements and bugfixes.
Kotlin 1.8.21 is used by default.

New set of Native targets

The official Kotlin target support policy has recently been published
describing new target policy: each target belongs to a certain tier, and different tiers have different stability guarantees.
The official recommendation for library authors is to support targets up to Tier 3,
and kotlinx.serialization now follows it.
It means that in this release, there are a lot of new targets added from this tier,
such as androidNativeX86 or watchosDeviceArm64.
Note that since they belong to Tier 3, they're not auto-tested on CI.

kotlinx.serialization also ships some deprecated Kotlin/Native targets that do not belong to any tier (e.g. iosArm32, mingwX86).
We'll continue to release them, but we do not provide support for them, nor do we plan to add new targets from the deprecated list.

Improvements in Json elements

There are two new function sets that should make creating raw Json elements easier.
First one contains overloads for JsonPrimitive constructor-like function
that accept unsigned types: JsonPrimitive(1u).
Second one adds new addAll functions to JsonArrayBuilder to be used with collections
of numbers, booleans or strings: buildJsonArray { addAll(listOf(1, 2, 3)) }
Both were contributed to us by aSemy.

Other enhancements

• Potential source-breaking change: Rename json-okio target variables to sink (#​2226)
• Function to retrieve KSerializer by KClass and type arguments serializers (#​2291)
• Added FormatLanguage annotation to Json methods (#​2234)
