Release Notes

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

v1.11.0

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

This release is based on Kotlin 2.3.20 and provides new Json exceptions API and some bugfixes and improvements.

Expose Json exceptions structure

To make working with exceptions easier and providing proper error codes in e.g., REST APIs,
classes JsonException, JsonDecodingException, and JsonEncodingException are now public.
They have relevant public properties, such as shortMessage, path, offset, and others.
This API is currently experimental, and we're going to improve it further in the subsequent releases.
See the linked issues for the details: #​1930, #​1877.

Ability to hide user input from exception messages for security/privacy reasons.

Historically, exception messages in kotlinx.serialization often included the input Json itself for debuggability reason.
Such behavior may pose additional challenges for logging, analytics, and other systems, since
a system is not always allowed to store user data due to privacy/security reasons, which imposes additional sanitation logic.
To address this issue, a new property exceptionsWithDebugInfo is added to JsonConfiguration.
Disable it to hide user input from exception messages.
IMPORTANT: This behavior will be enabled by default when this property becomes stable.
See #​2590 for more details.

Bugfixes and improvements

  • CBOR: Relax value range check when decoding numbers (#​3167)
  • Use a specialized writeDecimalLong method for IO stream integrations in Json (#​3152)

v1.10.0

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

This release is based on Kotlin 2.3.0 and contains all of the changes from 1.10.0-RC.
The only additional change is a fix for ProtoBuf packing of Kotlin unsigned types (#​3079).
Big thanks to KosmX for contributing the fix.

For your convenience, the changelog for 1.10.0-RC is duplicated below:

Stabilization of APIs

kotlinx-serialization 1.10 and subsequent releases will be focused on stabilization of existing APIs.
The following APIs and configuration options are no longer experimental because they're widely used without any known major issues:

  • Json configuration options: decodeEnumsCaseInsensitive, allowTrailingComma, allowComments, and prettyPrintIndent. (#​3100)
  • @EncodeDefault annotation and its modes. (#​3106)
  • JsonUnquotedLiteral constructor function (#​2900)
  • JsonPrimitive constructor function overloads that accept unsigned types. (#​3117)
  • JSON DSL functions on JsonElement with Nothing? overloads. (#​3117)

Readiness for return value checker

Kotlin 2.3.0 introduces a new feature aimed
at helping you to catch bugs related to the accidentally ignored return value of the function.
kotlinx-serialization 1.10.0-RC code is fully marked for this feature, meaning that you
can get warnings for unused function calls like Json.encodeToString(...).
To get the warnings, the feature has to be enabled in your project as described here.

Polymorphism improvements

Polymorphic serialization received a couple of improvements in this release:

New subclassesOfSealed utility to automatically register sealed subclasses serializers in polymorphic modules (#​2201).
Use it in your SerializersModule when configuring a polymorphic hierarchy which contains both abstract and sealed classes.
For example, when root of your hierarchy is an interface, but most of your inheritors are sealed classes.
The new function will register all known sealed subclasses for you, so you don’t need to list them one by one.
This makes writing your SerializerModules much faster and simpler.
Big thanks to Paul de Vrieze for contributing this feature.

Class discriminator conflict check rework (#​3105).
If a payload already contains a property with the same name as the configured discriminator (for example, type),
it is called a class discriminator conflict.
To produce a correct output and allow more inputs to be deserialized at the same time, the following changes were made:

  • Conflicts introduced by JsonNamingStrategy transformations are now detected during serialization as well and will cause SerializationException.
    It also affects non-polymorphic classes.
  • Conflicts from ClassDisciminatorMode.ALL_JSON_OBJECTS and SerializersModuleBuilder.polymorphicDefaultSerializer are also detected.
  • It is allowed to deserialize such a conflicting key for both sealed and open polymorphic hierarchies.
    Previously, it was possible in the sealed hierarchies alone due to missing assertion. See #​1664 for details.

General improvements

  • Add .serialName to MissingFieldException for clearer diagnostics. (#​3114)
  • Generate unique Automatic-Module-Name entries for metadata JARs. (#​3109)
  • Revised ProGuard rules and added R8 tests. (#​3041)
  • CBOR: Improved error message when a byte string/array type mismatch is encountered. (#​3052)

Bugfixes

  • Fix the type in the BIGNUM_NEGATIVE tag name. (#​3090)
  • CBOR: Fix various bugs in the decoder implementation to be more strict and consistent with the specification.

v1.9.0

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

This release updates Kotlin version to 2.2.0, includes several bugfixes and provides serializers for kotlin.time.Instant.

Add kotlin.time.Instant serializers

Instant class was moved from kotlinx-datetime library to Kotlin standard library.
As a result, kotlinx-datetime 0.7.0 no longer has serializers for the Instant class.
To use new kotlin.time.Instant class in your @​Serializable classes,
you can use this 1.9.0 kotlinx-serialization version (Kotlin 2.2 is required).
You can choose between default InstantSerializer which uses its string representation,
or specify InstantComponentSerializer that represents instant as its components.
See details in the PR.

Other bugfixes

  • Fix resize in JsonPath (#​2995)
  • Fixed proguard rules for obfuscation to work correctly (#​2983)
