v1.8.0

Compare Source

• kotlinx-coroutines-debug is published with the correct Java 9 module info (#​3944).
• kotlinx-coroutines-debug no longer requires manually setting DebugProbes.enableCoroutineCreationStackTraces to false, it's the default (#​3783).

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).
