Release Notes

Kotlin/kotlinx.coroutines (org.jetbrains.kotlinx:kotlinx-coroutines-bom)

v1.11.0

Compare Source

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).

New features

• c1bbb47 Started inferring the stability of all interfaces to be
  Stability.Unknown, expect for those explicitly marked as known
  stable.

Fixes

• b/511102714 Made the default stability of non-final classes Unknown
  instead of Stable
• b/509945632 Do not generate groups in inline lambdas without @Composable calls.
• b/504284805 Fix indentation for generated proguard mappings.
• b/422193018 Fix applier inference for nested composables of different types.
• b/497751457 Prevent a $stable property from being added to any object.
• b/427530633 Do not infer a getter call as static across when it is defined in another file.
• b/427530633 Started using Stability.Runtime more broadly. Now, when an
  element depends on the stability of an internal or public class
  defined in another file, the element will no longer infer the
  stability of that class and will depend on the runtime stability of
  that class instead.
