Full Changelog: google/ksp@2.3.0...2.3.1

v2.3.0

Compare Source

What's Changed

• KSP1 has been deprecated #​2657
• KSP version is no longer tied to the Kotlin compiler version (moving away from the old - format). #​2658
• KSP is no longer a compiler plugin (like KSP1). It now operates as a more standalone tool built on stable compiler APIs (shared with tools like IntelliJ).
• KSP now has fewer limitations on the Kotlin version in use and allows the KSP team to provide better compatibility to KGP/AGP/Gradle
• Read more about KSP2: https://github.com/google/ksp/blob/main/docs/ksp2.md

Reason for 2.3.0 version name:

• It is independent of Kotlin now
• We wanted to match the Kotlin language version
• It is newer than the latest KSP 2.2.20-2.0.4 release.

Full Changelog: google/ksp@2.2.20-2.0.4...2.3.0

What's Changed

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. Before, 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).
