 # Change log for kotlinx.coroutines
 
+## Version 1.3.4
+
+### Flow
+
+* Detect missing `awaitClose` calls in `callbackFlow` to make it less error-prone when used with callbacks (#1762, #1770). This change makes `callbackFlow` **different** from `channelFlow`.
+* `ReceiveChannel.asFlow` extension is introduced (#1490).
+* Enforce exception transparency invariant in `flow` builder (#1657).
+* Proper `Dispatcher` support in `Flow` reactive integrations (#1765).
+* Batch `Subscription.request` calls in `Flow` reactive integration (#766).
+* `ObservableValue.asFlow` added to JavaFx integration module (#1695).
+* `ObservableSource.asFlow` added to RxJava2 integration module (#1768).
+
+### Other changes
+
+* `kotlinx-coroutines-core` is optimized for R8, making it much smaller for Android usages (75 KB for `1.3.4` release).
+* Performance of `Dispatchers.Default` is improved (#1704, #1706).
+* Kotlin is updated to 1.3.70.
+* `CoroutineDispatcher` and `ExecutorCoroutineDispatcher` experimental coroutine context keys are introduced (#1805).
+* Performance of various `Channel` operations is improved (#1565).
