• Closeable dispatchers are instances of AutoCloseable now (#​4123).

Fixes

• Calling hasNext on a Channel's iterator is idempotent (#​4065). Thanks, @​gitpaxultek!

• 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).

Other

• Kotlin was updated to 2.0 (#​4137).

• Flow.timeout throws the exception with which the channel was closed (#​4071).
• Small documentation fixes.

v1.8.0

Compare Source

• kotlinx-coroutines-test: fixed a bug that could lead to not all uncaught exceptions being reported after some tests failed (#​3800).
• delay(Duration) rounds nanoseconds up to whole milliseconds and not down (#​3920). Thanks @​kevincianfarini!
• Dispatchers.Default and the default thread for background work are guaranteed to use the same context classloader as the object containing it them (#​3832).
• It is guaranteed that by the time SharedFlow.collect suspends for the first time, it's registered as a subscriber for that SharedFlow (#​3885). Before, it was also true, but not documented.
