React's Turbopack integration now supports an experimental array format that lets you dynamically merge or unmerge chunks based on what's already loaded in the browser.

The new chunk format [1] introduces a union type that pairs chunk URLs with metadata about path dependencies and loaded chunks, enabling smarter bundling decisions at runtime. This is the foundation work behind Next.js's forthcoming optimization [1], which will let frameworks ship fewer bytes by consolidating chunks intelligently. Meanwhile, React's Flight layer got a performance boost [2] that caps development stack traces at 10 frames during JSX call site reconstruction, cutting overhead for teams relying on detailed error context. On React Native, the team dropped the chrome-launcher dependency [3] after Expo flagged it as a papercut, removing duplicate code and lightening the core package. The same team also fixed Android RTL direction detection [4] to read from the active device locale instead of an arbitrary system locale, solving a layout bug that affected internationalized apps.
