Release Notes

Kotlin/kotlinx.coroutines

v1.6.4

Compare Source

• Added TestScope.backgroundScope for launching coroutines that perform work in the background and need to be cancelled at the end of the test (#​3287).
• Fixed the POM of kotlinx-coroutines-debug having an incorrect reference to kotlinx-coroutines-bom, which cause the builds of Maven projects using the debug module to break (#​3334).
• Fixed the Publisher.await functions in kotlinx-coroutines-reactive not ensuring that the Subscriber methods are invoked serially (#​3360). Thank you, @​EgorKulbachka!
• Fixed a memory leak in withTimeout on K/N with the new memory model (#​3351).
• Added the guarantee that all Throwable implementations in the core library are serializable (#​3328).
• Moved the documentation to https://kotlinlang.org/api/kotlinx.coroutines/ (#​3342).
• Various documentation improvements.

v1.6.3

Compare Source

• Updated atomicfu version to 0.17.3 (#​3321), fixing the projects using this library with JS IR failing to build (#​3305).

v1.6.2

Compare Source

• Fixed a bug with ThreadLocalElement not being correctly updated when the most outer suspend function was called directly without kotlinx.coroutines (#​2930).
• Fixed multiple data races: one that might have been affecting runBlocking event loop, and a benign data race in Mutex (#​3250, #​3251).

• 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).

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).

v1.5.0

Compare Source

Note that this is a full changelog relative to 1.4.3 version. Changelog relative to 1.5.0-RC can be found in the end.

Channels API

• Major channels API rework (#​330, #​974). Existing offer, poll, and sendBlocking methods are deprecated, internal receiveCatching and onReceiveCatching removed, receiveOrNull and onReceiveOrNull are completely deprecated. Previously deprecated SendChannel.isFull declaration is removed. Channel operators deprecated with ERROR are now HIDDEN.
