Updated atomicfu version to 0.17.3 (#3321), fixing the projects using this library with JS IR failing to build (#3305).
1.6.2
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).
Obsolete TestCoroutineContext is removed, which fixes the kotlinx-coroutines-test JPMS package being split between kotlinx-coroutines-core and kotlinx-coroutines-test (#3218).
Updated the ProGuard rules to further shrink the size of the resulting DEX file with coroutines (#3111, #3263). Thanks, @agrieve!
Atomicfu is updated to 0.17.2, which includes a more efficient and robust JS IR transformer (#3255).
Kotlin is updated to 1.6.21, Gradle version is updated to 7.4.2 (#3281). Thanks, @wojtek-kalicinski!
Various documentation improvements.
1.6.1
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.
1.6.0
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.
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).
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.
