Updates org.jetbrains.kotlinx:kotlinx-serialization-json from 1.8.1 to 1.11.0

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-serialization-json's releases.

1.11.0

This release is based on Kotlin 2.3.20 and provides a 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)

1.10.0

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

Updates org.jetbrains.kotlinx:kotlinx-coroutines-core from 1.10.2 to 1.11.0

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-coroutines-core's releases.

1.11.0

Various

• Kotlin was updated to 2.2.20 (#4545).
• Improved the published jar files (#3842, #4599).
• Various documentation improvements, including complete rewrites of structured concurrency and error handling-related KDoc (#4433, #4596).

Breaking changes and deprecations

• Moved Promise-related functions from JS and Wasm/JS to the new web target. On Wasm/JS, this is a breaking change. Before the change, Promise on Wasm/JS could work with arbitrary Kotlin types, but now, only JsAny subtypes are accepted (#4563).
• Changed handling of coroutine exceptions that can't be propagated on JS and Wasm/JS. B efore, exceptions were logged, but now, they are reported to the JS runtime (#4451, #4631).
• Deprecated using CoroutineDispatcher as the coroutine context key; now, ContinuationInterceptor has to be used instead (#4333).
• Advanced the deprecation levels on kotlinx-coroutines-test APIs (#4604).
• Added lint functions that mark passing a Job to coroutine builders as deprecated (#4435).

Bug fixes and improvements

• Added a callsInPlace(EXACTLY_ONCE) contract to runBlocking in code shared between JVM and Native (#4368).
• Added a callsInPlace(EXACTLY_ONCE) contract to suspendCancellableCoroutine (#4574).
• Fixed flowOn incorrectly handling ThreadContextElement updates (#4403).
• Fixed exceptions in user-supplied Thread.UncaughtExceptionHandler instances causing the internal coroutines machinery to fail (#4516).
• Fixed CoroutineDispatcher.asScheduler in the RxJava integration not cancelling outstanding work when a Worker gets cancelled, which led to memory leaks in some scenarios (#4615).
• Fixed SharedFlow entering an invalid state when a subscriber and an emitter are cancelled simultaneously (#4583).
• Fixed an R8 optimization leading to shareIn/stateIn coroutines getting garbage-collected (#4646). Thanks, @​solevic!

Small additions

• Added CompletableDeferred.asDeferred for obtaining a read-only Deferred view (#4408).
• Added SharedFlow.asFlow for obtaining a Flow view with hidden hot flow semantics (#4530). Thanks, @​g000sha256!
• Added a StateFlow.collectLatest overload returning Nothing to assist with finding unreachable code (#4454).
• Added ReceiveChannel.consumeTo for consuming a ReceiveChannel into a MutableCollection (#4520).
• Added a StateFlow<T>.onSubscription overload returning a StateFlow<T>, similar to SharedFlow<T>.onSubscription returning SharedFlow<T> (#4275). Thanks, @​xit0c!
• Added terminal Flow operators for collecting a Flow to a Map (#1541).

Changelog relative to version 1.11.0

No changes, only the version is increased.

1.11.0-rc02

Restored binary compatibility with 1.10.2 and older versions on Wasm/JS for usages of Promise-related functions (#4661).

1.11.0-rc01

Updates org.jetbrains.kotlinx:kotlinx-coroutines-test from 1.10.2 to 1.11.0

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-coroutines-test's releases.

1.11.0

Various

• Kotlin was updated to 2.2.20 (#4545).
• Improved the published jar files (#3842, #4599).
• Various documentation improvements, including complete rewrites of structured concurrency and error handling-related KDoc (#4433, #4596).

Breaking changes and deprecations

• Moved Promise-related functions from JS and Wasm/JS to the new web target. On Wasm/JS, this is a breaking change. Before the change, Promise on Wasm/JS could work with arbitrary Kotlin types, but now, only JsAny subtypes are accepted (#4563).
• Changed handling of coroutine exceptions that can't be propagated on JS and Wasm/JS. B efore, exceptions were logged, but now, they are reported to the JS runtime (#4451, #4631).
• Deprecated using CoroutineDispatcher as the coroutine context key; now, ContinuationInterceptor has to be used instead (#4333).
• Advanced the deprecation levels on kotlinx-coroutines-test APIs (#4604).
• Added lint functions that mark passing a Job to coroutine builders as deprecated (#4435).

Bug fixes and improvements

• Added a callsInPlace(EXACTLY_ONCE) contract to runBlocking in code shared between JVM and Native (#4368).
• Added a callsInPlace(EXACTLY_ONCE) contract to suspendCancellableCoroutine (#4574).
• Fixed flowOn incorrectly handling ThreadContextElement updates (#4403).
• Fixed exceptions in user-supplied Thread.UncaughtExceptionHandler instances causing the internal coroutines machinery to fail (#4516).
• Fixed CoroutineDispatcher.asScheduler in the RxJava integration not cancelling outstanding work when a Worker gets cancelled, which led to memory leaks in some scenarios (#4615).
• Fixed SharedFlow entering an invalid state when a subscriber and an emitter are cancelled simultaneously (#4583).
• Fixed an R8 optimization leading to shareIn/stateIn coroutines getting garbage-collected (#4646). Thanks, @​solevic!

Small additions

• Added CompletableDeferred.asDeferred for obtaining a read-only Deferred view (#4408).
• Added SharedFlow.asFlow for obtaining a Flow view with hidden hot flow semantics (#4530). Thanks, @​g000sha256!
• Added a StateFlow.collectLatest overload returning Nothing to assist with finding unreachable code (#4454).
• Added ReceiveChannel.consumeTo for consuming a ReceiveChannel into a MutableCollection (#4520).
• Added a StateFlow<T>.onSubscription overload returning a StateFlow<T>, similar to SharedFlow<T>.onSubscription returning SharedFlow<T> (#4275). Thanks, @​xit0c!
• Added terminal Flow operators for collecting a Flow to a Map (#1541).
