Bumps kotlinx-coroutines from 1.8.1 to 1.9.0.
Updates org.jetbrains.kotlinx:kotlinx-coroutines-core from 1.8.1 to 1.9.0

Release notes

Sourced from org.jetbrains.kotlinx:kotlinx-coroutines-core's releases.

1.9.0

Features

  • Wasm/WASI target support (#4064). Thanks, @​igoriakovlev!
  • limitedParallelism now optionally accepts the name of the dispatcher view for easier debugging (#4023).
  • No longer initialize Dispatchers.IO on the JVM when other standard dispatchers are accessed (#4166). Thanks, @​metalhead8816!
  • Introduced the Flow<T>.chunked(size: Int): Flow<List<T>> operator that groups emitted values into groups of the given size (#1290).
  • Closeable dispatchers are instances of AutoCloseable now (#4123).

Fixes

  • Calling hasNext on a Channel's iterator is idempotent (#4065). Thanks, @​gitpaxultek!
  • CoroutineScope() created without an explicit dispatcher uses Dispatchers.Default on Native (#4074). Thanks, @​whyoleg!
  • Fixed a bug that prevented non-Android Dispatchers.Main from initializing when the Firebase dependency is used (#3914).
  • Ensured a more intuitive ordering of tasks in runBlocking (#4134).
  • Forbid casting a Mutex to Semaphore (#4176).
  • Worked around a stack overflow that may occur when calling asDeferred on a Future many times (#4156).

Deprecations and promotions

  • Advanced the deprecation levels for BroadcastChannel-based API (#4197).
  • Advanced the deprecation levels for the old kotlinx-coroutines-test API (#4198).
  • Deprecated Job.cancelFutureOnCompletion (#4173).
  • Promoted CoroutineDispatcher.limitedParallelism to stable (#3864).
  • Promoted CoroutineStart.ATOMIC from ExperimentalCoroutinesApi to DelicateCoroutinesApi (#4169).
  • Promoted CancellableContinuation.resume with an onCancellation lambda to stable, providing extra arguments to the lambda (#4088).
  • Marked the classes and interfaces that are not supposed to be inherited from with the new InternalForInheritanceCoroutinesApi opt-in (#3770).
  • Marked the classes and interfaces inheriting from which is not stable with the new ExperimentalForInheritanceCoroutinesApi opt-in (#3770).

Other

  • Kotlin was updated to 2.0 (#4137).
  • Reworked the documentation for CoroutineStart and Channel-based API (#4147, #4148, #4167). Thanks, @​globsterg!

  • Small tweaks, fixes, and documentation improvements.
