Release Notes

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

v1.12.0

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

This release is based on Kotlin 2.4.10 and contains all of the changes from 1.12.0-RC.

Additionally, it includes a fix removing unnecessary leading whitespaces from Proguard rules (#​3270),
and two changes stabilizing kotlin.uuid.Uuid serializer (#​3263) and kotlin.time.Instant serializers (#​3261).

For your convenience, the changelog for 1.12.0-RC is duplicated below:

API stabilization and deprecations

A big portion of the Json and Core APIs has been stabilized. Most important ones include:
@KeepGeneratedSerializer and @SerialInfo annotations, JsonNamingStrategy, and ContextualSerializer.
Additionally, various descriptor builders such as listDescriptor and JsonElementBuilder's addAll functions are also
stable and can be freely used. There is also one deprecation: ChunkedDecoder interface. Since there is no demand for
it, we plan to remove it in the future. See details in
the #​3238, #​3239,
and #​3216.

Also, kotlin.time.Instant and kotlin.uuid.Uuid serializers are no longer annotated with experimental annotations
from the Kotlin standard library (see [#​3261](#​3261
and #​3263)

Performance improvements

We also improved performance in various areas. ASCII-specific parser
(#​3225) brings performance of decoding from Okio and
kotlinx-io sources closer to decoding performance from
String. #​3220 makes decoding significantly faster in case
JsonElement present in your serializable classes.
And #​3248 should bring overall performance improvements
(up to 30%) on large strings.

Exceptions rework

We continue to improve exception handling in Json encoders and decoders.
#​3235 makes a big change around custom serializers and
@Serializable classes constructors:
from now on, every exception thrown during deserialization is wrapped by decoder into a JsonException. This way, it is
more predictable to write a catch and it is easier to understand what went wrong:
JsonDecodingException also includes context information such as Json path and input. Besides
that, #​3246 limits maximum nesting depth of Json
document, so you will get a proper JsonDecodingException instead of a random stack overflow error.

CBOR improvements

CBOR format also gets many improvements in this release. The most important one is memory optimization for
definitely-sized collections (#​3191, #​3192).

The others include:

• Encode unsigned integer types as positive integers (#​3194) (thanks to Eyüp Can Akman)
• Correctly decode CborLabel values (#​3195)
• Include actual tag info into CborDecodingException (#​3197)

Protobuf improvements

Protocol buffers format received a big new feature: support for unknown fields. Using a new ProtoUnknownFieldHolder
class, you can now decode and store unknown fields in Protobuf messages to retransmit them back later. See documentation
updates and #​2860 for details. Big thanks
to xzk for theirs contributions:
this one and the bug with oneof default value (#​3147).

We've also fixed Protobuf schema generation for inlined value classes (#​3209).

Other improvements and bugfixes

• Set Deprecated (HIDDEN) to setters in JsonConfiguration
• Add Json nesting depth calculation during parsing (#​3246)
• JsonElementBuilders: mark all (add|put)Json (Object|Array) functions as inline (#​3242) (thanks to Miha-x64)
• Fix Polymorphic Deserialization Error with Subclass using JsonTransformingSerializer (#​3139) (thanks to YongJun Jung)
• Align collections' SerialDescriptors with the contract (#​3199)
• Remove leading whitespace from Proguard rules (#​3270)
