Hello, it's September 30th, 2026, and this is your React Native briefing.

The big picture today is under-the-hood hardening: a faster Android animation pipeline, the end of a persistent Android styling crash, and tighter boundaries for native C++ headers.

First, animation performance. Four connected pull requests rework how animated props reach Android views. Instead of one bridge call per view per frame, a surface's updates are now encoded once and applied in a single call — that's PR 58765. PR 58764 adds the batched scheduler entry point to enable it, with a…

Second, Android reliability for percentage corners. Commit 5fc6ccb fixes the crash when setting a percentage border radius on Text, Text Input, and Scroll View. Percentages arrive as strings like 50 percent, which broke the old float-only setters. They now parse as flexible length percentages, matching earlier fixes…

Third, native API cleanup. PRs 58742, 58743 and 58744 move feature flags to private and generate a narrow public entry point for exported headers. Related changes switch Image, UIManager, and animation headers to umbrella imports and isolate implementation details.

Also noteworthy: structured clone and D-O-M…
