Release Notes

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

### [`v1.7.1`](https://togithub.com/Kotlin/kotlinx.serialization/blob/HEAD/CHANGELOG.md#171--2024-06-25) [Compare Source](https://togithub.com/Kotlin/kotlinx.serialization/compare/v1.7.0...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](https://togithub.com/Kotlin/kotlinx.serialization/issues/2717). #### Add integration with a kotlinx-io library [`kotlinx-io`](https://togithub.com/Kotlin/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](https://kotlinlang.org/api/kotlinx.serialization/kotlinx-serialization-json-okio/kotlinx.serialization.json.okio/): `encodeToSink`, `decodeFromSource`, and `decodeSourceToSequence`. Check out the [PR](https://togithub.com/Kotlin/kotlinx.serialization/pull/2707) for more details. #### Other bugfixes - Prohibited use of elements other than JsonObject in JsonTransformingSerializer with polymorphic serialization ([#​2715](https://togithub.com/Kotlin/kotlinx.serialization/issues/2715))
