Release Notes

Kotlin/kotlinx.serialization

v1.3.2

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

This release contains several features and bugfixes for core API as well as for HOCON format.
It uses Kotlin 1.6.10 by default.

Serializing objects to HOCON

It's now possible to encode Kotlin objects to Config values with new Hocon.encodeToConfig function.
This feature may help edit existing configs inside Kotlin program or generate new ones.

Big thanks to Osip Fatkullin for implementing this.

Polymorphic default serializers

As of now, polymorphicDefault clause inside SerializersModule { } builder specifies a
fallback serializer to be used only during deserialization process. A new function has been introduced to allow setting
fallback serializer for serialization: polymorphicDefaultSerializer.
This function should ease serializing vast hierarchies of third-party or Java classes.

Note that there are two new experimental functions, polymorphicDefaultSerializer and polymorphicDefaultDeserializer.
To avoid naming confusion, we are going to deprecate polymorphicDefault in favor of polymorphicDefaultDeserializer in the next minor release (1.4.0).

Credit for the PR goes to our contributor Joseph Burton.

Other improvements

• HOCON: parse strings into integers and booleans if possible (#​1795) (thanks to tobiaslieber)
• Add an encodeCollection extensions (#​1749) (thanks to Nicklas Ansman Giertz)

Bugfixes

• Properly handle top-level value classes in encodeToJsonElement (#​1777)
• Fix incorrect handling of object end when JsonTreeReader (JsonElement) is used with decodeToSequence (#​1782)

Kotlin/kotlinx.coroutines

v1.6.1

Compare Source

• Rollback of time-related functions dispatching on Dispatchers.Main.
  This behavior was introduced in 1.6.0 and then found inconvenient and erroneous (#​3106, #​3113).
• Reworked the newly-introduced CopyableThreadContextElement to solve issues uncovered after the initial release (#​3227).
• Fixed a bug with ThreadLocalElement not being properly updated in racy scenarios (#​2930).
• Reverted eager loading of default CoroutineExceptionHandler that triggered ANR on some devices (#​3180).
• New API to convert a CoroutineDispatcher to a Rx scheduler (#​968, #​548). Thanks @​recheej!
• Fixed a memory leak with the very last element emitted from flow builder being retained in memory (#​3197).
• Fixed a bug with limitedParallelism on K/N with new memory model throwing ClassCastException (#​3223).
• CoroutineContext is added to the exception printed to the default CoroutineExceptionHandler to improve debuggability (#​3153).
• Static memory consumption of Dispatchers.Default was significantly reduced (#​3137).
• Updated slf4j version in kotlinx-coroutines-slf4j from 1.7.25 to 1.7.32.

v1.6.0

Compare Source

Note that this is a full changelog relative to the 1.5.2 version. Changelog relative to 1.6.0-RC3 can be found at the end.

kotlinx-coroutines-test rework

• kotlinx-coroutines-test became a multiplatform library usable from K/JVM, K/JS, and K/N.
• Its API was completely reworked to address long-standing issues with consistency, structured concurrency and correctness (#​1203, #​1609, #​2379, #​1749, #​1204, #​1390, #​1222, #​1395, #​1881, #​1910, #​1772, #​1626, #​1742, #​2082, #​2102, #​2405, #​2462
  ).
• The old API is deprecated for removal, but the new API is based on the similar concepts (README), and the migration path is designed to be graceful: migration guide.

Dispatchers

• Introduced CoroutineDispatcher.limitedParallelism that allows obtaining a view of the original dispatcher with limited parallelism (#​2919).
• Dispatchers.IO.limitedParallelism usages ignore the bound on the parallelism level of Dispatchers.IO itself to avoid starvation (#​2943).
• Introduced new Dispatchers.shutdown method for containerized environments (#​2558).
• newSingleThreadContext and newFixedThreadPoolContext are promoted to delicate API (#​2919).

Breaking changes

• When racing with cancellation, the future builder no longer reports unhandled exceptions into the global CoroutineExceptionHandler. Thanks @​vadimsemenov! (#​2774, #​2791).
• Mutex.onLock is deprecated for removal (#​2794).
• Dispatchers.Main is now used as the default source of time for delay and withTimeout when present(#​2972).
  • To opt-out from this behaviour, kotlinx.coroutines.main.delay system property can be set to false.
• Java target of coroutines build is now 8 instead of 6 (#​1589).
• Source-breaking change: extension collect no longer resolves when used with a non-in-place argument of a functional type. This is a candidate for a fix, uncovered after 1.6.0, see #​3107 for the additional details.

Bug fixes and improvements

• Kotlin is updated to 1.6.0.
• Kotlin/Native new memory model is now supported in regular builds of coroutines conditionally depending on whether kotlin.native.binary.memoryModel is enabled (#​2914).
• Introduced CopyableThreadContextElement for mutable context elements shared among multiple coroutines. Thanks @​yorickhenning! (#​2893).
• transformWhile, awaitClose, ProducerScope, merge, runningFold, runingReduce, and scan are promoted to stable API (#​2971).
• SharedFlow.subscriptionCount no longer conflates incoming updates and gives all subscribers a chance to observe a short-lived subscription (#​2488, #​2863, #​2871).
• Flow exception transparency mechanism is improved to be more exception-friendly (#​3017, #​2860).
• Cancellation from flat* operators that leverage multiple coroutines is no longer propagated upstream (#​2964).
• SharedFlow.collect now returns Nothing (#​2789, #​2502).
• DisposableHandle is now fun interface, and corresponding inline extension is removed (#​2790).
• FlowCollector is now fun interface, and corresponding inline extension is removed (#​3047).
• Deprecation level of all previously deprecated signatures is raised (#​3024).
• The version file is shipped with each JAR as a resource (#​2941).
• Unhandled exceptions on K/N are passed to the standard library function processUnhandledException (#​2981).
• A direct executor is used for Task callbacks in kotlinx-coroutines-play-services (#​2990).
• Metadata of coroutines artifacts leverages Gradle platform to have all versions of dependencies aligned (#​2865).
• Default CoroutineExceptionHandler is loaded eagerly and does not invoke ServiceLoader on its exception-handling path (#​2552).
• Fixed the R8 rules for ServiceLoader optimization (#​2880).
• Fixed BlockHound integration false-positives (#​2894, #​2866, #​2937).
• Fixed the exception handler being invoked several times on Android, thanks to @​1zaman (#​3056).
• SendChannel.trySendBlocking is now available on Kotlin/Native (#​3064).
• The exception recovery mechanism now uses ClassValue when available (#​2997).
• JNA is updated to 5.9.0 to support Apple M1 (#​3001).
• Obsolete method on internal Delay interface is deprecated (#​2979).
• Support of deprecated CommonPool is removed.
• @ExperimentalTime is no longer needed for methods that use Duration (#​3041).
• JDK 1.6 is no longer required for building the project (#​3043).
• New version of Dokka is used, fixing the memory leak when building the coroutines and providing brand new reference visuals (https://kotlin.github.io/kotlinx.coroutines/) (#​3051, #​3054).

Changelog relative to version 1.6.0-RC3

• Restored MPP binary compatibility on K/JS and K/N (#​3104).
• Fixed Dispatchers.Main not being fully initialized on Android and Swing (#​3101).
