React 19.3 shipped on September 9, 2026. Two APIs that have been sitting in the experimental drawer since the April 2025 React Labs post — <ViewTransition> and Fragment Refs — are now stable, joined by a browser() escape hatch for SSR, Trusted Types passthrough, and Context rendering in Server Components. There are no breaking changes, no deprecations, no codemods, and no upgrade guide, because none are needed. The interesting question isn't whether to bump the version. It's which of these APIs earn a place in your codebase.

AG-UI (Agent User Interaction Protocol) is an open, event-based protocol that standardizes how AI agents communicate with user-facing applications. Created by CopilotKit and adopted by Microsoft, Google, AWS, LangChain, and CrewAI, it fills the gap between MCP (agent↔tools) and A2A (agent↔agent) by defining the agent↔UI layer. It's MIT licensed with 14.4k GitHub stars and 50+ framework integrations.

Remember when we said this was an experiment? Well, the experiment grew up. We just shipped a curated, 13-tool Recommended Tech Stack for Aliz frontend projects — a single reference for what we reach for when starting something new.
