Hello, it's October 22nd, 2026, and here's your React Native briefing.
The big story is speed plus simplification. Native layout and text work is getting measurably faster, while leftovers from the old bridge are finally being deleted.
First, performance. PR 59226 switches iOS release builds from optimize-for-size to optimize-for-speed, matching Android. In benchmarks, yoga layout was 21 to 54 percent faster, with debug builds up to 16 times faster, at the cost of about 6 percent larger stripped binary. Commit 79a5629 cuts differ time another way,…
Second, the legacy bridge is going away in code, not just docs. Five related PRs, including 59315 and 59323, delete unused bridge categories, the old profiling hook, dead imports, and skipped tests. A related commit drops bridge reads from five new-architecture-only modules. Impact is maintainability and release…
Finally, reliability and testing. Commit 0f17f27 fixes Android scroll views stuck in dragging state when a parent intercepts the gesture, now properly ending the drag on cancel. PR 59314 stops invalid elevation and scale values from crashing Android 9 and later. On testing, ten new visual suites from PRs 59338…
