Lee from Vercel here! Happy to answer any questions about this release, or Next.js in general. Personally, I'm very excited about the performance improvements we're seeing switching to Rust from Babel/Terser.

Could you please clarify what the ES Modules support change?

You can now import npm packages using ES Modules (e.g. "type": "module" in their package.json) with an experimental flag directly in Next.js. Previously, this required extra configuration.
