React Native is ripping out the feature flags that held back Fabric adoption and raising the Node.js floor by two major versions in the same commit wave.

The mobile team is finishing what it started: removing the `enableFabricRenderer()` flag entirely [1] [2], which always returned true on canary anyway. This is cleanup that signals Fabric is no longer experimental. They're also guarding legacy architecture tests behind compile macros [3] to stop build failures when old code paths get stripped. On tooling, React Native now requires Node.js 22.13.0 or better [4], dropping Node 20 entirely after it hit end-of-life in April 2026. This aligns with Metro's upcoming requirements and forces the ecosystem forward. A minor iOS fix removes unnecessary window handling code in LogBox on Mac Catalyst [5]. Over in Jest, Babel got bumped to rc.5 [6], and the team shipped mandatory changelog enforcement [7] [8] to keep PR history clean. They also nuked the unmaintained jest-pnp-resolver [10], replacing it with unrs-resolver 1.12.1 [9].
