React Native: Memory Pressure Fix, Accessibility Gaps and Text Precision
React Native now reports shadow node memory to the Hermes collector to stop unmounted trees piling up in native memory, while touchable role and aria props finally reach native views. Gradient, Android text, and mounting fixes round out the activity ahead of the 0.89 release candidate.

Good morning, it's November 5th, 2026, you're listening to the React Native briefing.
The throughline today is quiet correctness: less leaked native memory, fewer resurrected views, and props that finally reach the platform.
First, memory and mounting. Pull request 59702 reports the native size of newly created shadow nodes to the Hermes garbage collector as external memory pressure. In testing with a thousand views mounted and unmounted repeatedly, native heap after unmount fell from the mid-50s in megabytes to the mid-30s on Pixel…
Second, accessibility. Pull request 59378 fixes touchable components dropping the role property and several aria properties, meaning a button role, aria label, and states like busy, checked or expanded now reach the native view instead of silently disappearing. A related open change for image backgrounds would…
Third, pixels matching the web. Pull request 59774 interpolates gradient color stops outside zero to one hundred percent instead of clamping them, matching browsers and covering radial gradients. On Android text, pull request 59791 stops whole-pixel widths from wrapping due to rounding error, while another change…
On breaking changes, the…
