 # Change log for kotlinx.coroutines
 
+## Version 1.8.0-RC
+
+* Implement the library for the Web Assembly (Wasm) for JavaScript (#3713). Thanks @igoriakovlev!
+* On Android, ensure that `Dispatchers.Main != Dispatchers.Main.immediate` (#3545, #3963).
+* `kotlinx-coroutines-debug` is published with the incorrect Java 9 module info (#3944).
+* Major Kotlin version update: was 1.8.20, became 1.9.21.
+* `kotlinx-coroutines-test`: set the default timeout of `runTest` to 60 seconds, added the ability to configure it on the JVM with the `kotlinx.coroutines.test.default_timeout=10s` (#3800).
+* `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.
+* Atomicfu version is updated to 0.23.1, and Kotlin/Native atomic transformations are enabled, reducing the footprint of coroutine-heavy code (#3954).
+* Added a workaround for miscompilation of `withLock` on JS (#3881). Thanks @CLOVIS-AI!
+* Small tweaks and documentation fixes.
+
 ## Version 1.7.3
 
 * Disabled the publication of the multiplatform library metadata for the old (1.6 and earlier) KMP Gradle plugin (#3809).

 ### Using as JVM agent
 
 Debug module can also be used as a standalone JVM agent to enable debug probes on the application startup.

+You can run your application with an additional argument: `-javaagent:kotlinx-coroutines-debug-1.8.0-RC.jar`.
 Additionally, on Linux and Mac OS X you can use `kill -5 $pid` command in order to force your application to print all alive coroutines.
 When used as Java agent, `"kotlinx.coroutines.debug.enable.creation.stack.trace"` system property can be used to control 
 [DebugProbes.enableCreationStackTraces] along with agent startup.
