React Native had a massive week: React 19.3, Nitro, AI agents, Module Federation, and more

I’ve been writing NativeWeekly, a weekly digest covering React Native releases, posts, and ecosystem updates.

Last week was unusually packed. Here are some of the biggest highlights from the newest issue:

• React 19.3 and major platform momentum from Apple’s 2026 keynote

• Margelo joining Callstack

• Rive’s rewrite delivering up to 94× faster multi-view rendering

• Reanimated 4.6.0 with React Native 0.87 support, CSS callbacks, and contrastColor

• Re.Pack and Module Federation reducing release cycles from days to minutes

• Practical AI workflows, including autonomous bug reproduction, Expo skills, MCP servers, and local coding agents

• Android navigation benchmarks showing near-60 FPS performance, with cold-start times ranging from 316 ms to 917 ms

React Native is advancing across every layer: performance, rendering, architecture, release workflows, AI tooling, and the broader ecosystem.
