Welcome to the 33rd edition of React Native Weekly!

The week 45 of 2021 was a slower than usual week, it contains all the work in-between: November 1st to 7th.

Workflow for version labels

Lucas Bento lucas.bsilva@outlook.com’s commit added Github actions to 1) create a label for each released version and 2) automatically apply this label version when an issue is opened mentioning the given version.

If you want to take a look at the Github Actions Lucas created you can find them here: Create version label and Apply version label.

Add workflow to create version labels on new releases (#32508)

Changelog moved back to core repo

This commit adds the release changelog back to the core repo. It was previously hosted a React Native Community repo.

Improvements to Codegen

Ramanpreet Nara ramanpreet@fb.com and Héctor Ramos hramos@fb.com made a few changes to the Codegen logic.

Most notable Ramanpreet refactored the use of string replace for the use of templates.

Fix split-screen app reconstruct

somena1 sophiaesiri.ee@gmail.com fixed an issue related to split screen Android devices.

When switching between split screen or resizing the screen window on Android causes a restart by reconstructing the app components as described on this issue https://github.com/facebook/react-native/issues/25040

The fix is to add screenLayout and smallestScreenSize to AndroidManifest’s android:configChanges

Remove iOS 11 availability check

This commit by Ken Tominaga ken.for.develop@gmail.com is a good reminder that React Native mininum iOS deployment target is iOS 11.

Check for double dispose when sending touch event [Android]

Andrei Shikov ashikov@fb.com found a double dispatching issue with touch events on Android.

-      TouchesHelper.sendTouchEventModern(rctEventEmitter, this, /* useDispatchV2 */ true);
+      if (verifyMotionEvent()) {
+        TouchesHelper.sendTouchEventModern(rctEventEmitter, this, /* useDispatchV2 */ true);
+      }

Ensure WritableMap is copied before consuming object

In another commit Andrei Shikov ashikov@fb.com also fixed an issue with touch events where the touch objects would cause crash in production due to high-firing conditions for CANCEL events.

And this was caused by the WritableMap object not being properly copied over.
