Good morning, it's Monday, October 26th, 2026, and this is your React Native briefing.
The lead pattern today is correctness under edge conditions, with several Android fixes stopping leaked activities and stale views, alongside iOS parity and closer web-standard behavior.
First, Android memory and lifecycle. Two reports, in PRs 59472 and 59470, trace the same serious leak: a password input that received text was never released after unmount, because the text measurement cache kept a copy that referenced the input and through it, its host screen. The fix strips unneeded formatting…
Second, iOS scrolling and build parity. PR 59480 fixes horizontal scroll views in right-to-left layouts, where the scroll-to API and scroll events counted from opposite edges, breaking measurement and paging. Offsets now consistently count from the left edge, matching Android. On the release side, PR 59478 backports…
