Bump kotlinx-serialization-json from 1.0.1 to 1.2.0

[dependabot[bot]]

Bumps kotlinx-serialization-json from 1.0.1 to 1.2.0.

Release notes

Sourced from kotlinx-serialization-json's releases.

1.1.0

This release contains all features and bugfixes from 1.1.0-RC plus an additional fix for incorrect exception type (#1325 — Throw SerializationException instead of IllegalStateException in EnumSerializer) and uses release version of Kotlin 1.4.30.

In the light of JCenter shutdown, starting from 1.1.0-RC and now on, all new releases of kotlinx.serialization are published directly to Maven Central and therefore are not available in https://kotlin.bintray.com/kotlinx/ repository. We suggest you to remove jcenter() and other kotlin bintray repositories from your buildscripts and to use mavenCentral() repository instead.

1.1.0-RC

This is a release candidate of 1.1.0 version. Note that final 1.1.0 version may include more features and bugfixes, which would be listed in the corresponding changelog.

Kotlin version requirement updated

Due to changes in calling conventions between compiler plugin and serialization core runtime, this release requires Kotlin version at least 1.4.30-M1 (we recommend using 1.4.30 release version). However, these changes should not affect your code, because only deprecated functions were removed from public API. See corresponding PR for the details.

Experimental support for inline classes (IR only)

Using 1.1.0-RC, you can mark inline classes as @Serializable and use them in other serializable classes. Unsigned integer types (UByte, UShort, UInt and ULong) are serializable as well and have special support in JSON. This feature requires Kotlin compiler 1.4.30-RC and enabling new IR compilers for JS and JVM.

You can learn more in the documentation and corresponding pull request.

Changelog

1.2.0 / 2021-04-27

This release contains a lot of new features and important improvements listed below; Kotlin 1.5.0 is used as a default compiler and language version.

JSON performance improvements

JSON encoder and decoder were revisited and significantly rewritten, which lead us to up to 2-3x times speedup in certain cases. Additional details can be found in the corresponding issues: [1], [2].

Ability to specify alternative names during JSON decoding

The one of the most voted issues is fixed now — it is possible to specify multiple names for one property using new @JsonNames annotation. Unlike @SerialName, it only affects JSON decoding, so it is useful when dealing with different versions of the API. We've prepared a documentation for you about it.

JsonConfiguration in public API

JsonConfiguration is exposed as a property of Json instance. You can use it to adjust behavior in your custom serializers. Check out more in the corresponding issue and the PR.

Generator for .proto files based on serializable Kotlin classes

Our implementation of Protocol Buffers format uses @Serializable Kotlin classes as a source of schema. This is very convenient for Kotlin-to-Kotlin communication, but makes interoperability between languages complicated. To resolve this issue, we now have a schema generator that can produce .proto files out of Kotlin classes. Using it, you can keep Kotlin classes as a source of truth and use traditional protoc compilers for other languages at the same time. To learn more, check out the documentation for the new ProtoBufSchemaGenerator class or visit the corresponding PR.

Note: this generator is on its experimental stage and any feedback is very welcomed.

Contextual serialization of generic classes

Before 1.2.0, it was impossible to register context serializer for generic class, because contextual function accepted a single serializer. Now it is possible to register a provider — lambda that allows to construct a serializer for generic class out of its type arguments serializers. See the details in the documentation.

Other features

• Support for watchosX64 target (#1366).
• Introduce kotlinx-serialization-bom (#1356).
• Support serializer on JS IR when T is an interface (#1431).
