Next.js 10.1 – 3x Faster Refresh, Image Improvements, Apple Silicon Support

One interesting note not mentioned in the blog post. We've created new performance profiling tooling which will run on each commit into the Next.js repo. This tracks metrics like initial build times, fast refresh times, traces through the system, and more. We used this tooling to test large Next.js applications (our own as well as some Vercel customers) to measure Fast Refresh improvements. Excited for the future of Next.js!
