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](https://github.com/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](Kotlin/kotlinx.serialization#2945). #### Other bugfixes - Fix resize in JsonPath ([#​2995](Kotlin/kotlinx.serialization#2995)) - Fixed proguard rules for obfuscation to work correctly ([#​2983](Kotlin/kotlinx.serialization#2983)) ### [`v1.8.1`](https://github.com/Kotlin/kotlinx.serialization/blob/HEAD/CHANGELOG.md#181--2025-03-31) \================== This release updates Kotlin version to 2.1.20, while also providing several important improvements and bugfixes. #### Improvements - Implemented encoding null in key and value of a map in Protobuf ([#​2910](Kotlin/kotlinx.serialization#2910)) - Make type argument in JsonTransformingSerializer nullable ([#​2911](Kotlin/kotlinx.serialization#2911)) - Use SPDX identifier in POMs ([#​2936](Kotlin/kotlinx.serialization#2936)) (thanks to [Leon Linhart](https://github.com/TheMrMilchmann)) - Add watchosDeviceArm64 to Okio integration module ([#​2920](Kotlin/kotlinx.serialization#2920)) (thanks to [Daniel Santiago](https://github.com/danysantiago)) - Update kotlinx-io version to 0.6.0 ([#​2933](Kotlin/kotlinx.serialization#2933)) (thanks to [Piotr Krzemiński](https://github.com/krzema12)) #### Bugfixes - Fix incorrect enum coercion during deserialization from JsonElement ([#​2962](Kotlin/kotlinx.serialization#2962)) - Supply proper equals(), hashCode(), and toString() for SerialDescriptor() wrapper ([#​2942](Kotlin/kotlinx.serialization#2942)) - Do not encode empty packed collections in protobuf ([#​2907](Kotlin/kotlinx.serialization#2907)) ### [`v1.8.0`](https://github.com/Kotlin/kotlinx.serialization/blob/HEAD/CHANGELOG.md#180--2025-01-06) \================== This release contains all of the changes from 1.8.0-RC. Kotlin 2.1.0 is used as a default, while upcoming 2.1.10 is also supported. Also added small bugfixes, including speedup of ProtoWireType.from ([#​2879](Kotlin/kotlinx.serialization#2879)). </details> --- ### Configuration 📅 **Schedule**: Branch creation - "after 6pm every weekday,before 2am every weekday" in timezone Australia/Melbourne, Automerge - At any time (no schedule defined). 🚦 **Automerge**: Enabled. ♻ **Rebasing**: Never, or you tick the rebase/retry checkbox. 👻 **Immortal**: This PR will be recreated if closed unmerged.
