Our Commentary ​

Next.js continues to push the boundaries of full-stack React development. The introduction of Adapters is definitely something to read about for library authors and integrators. Improvements to Turbopack look awesome. Quicker startup times and faster rendering intensifies rivarly with Vite (who just introduced collaboration with Cloudflare). What a time to be alive. To be honest, from dev perspective, the new "Hydration Diff Indicator" might be a winner. I think everyone agrees that it was not always easy to find exact cause of hydration issues in Next.js. Hopefully that's now a thing of the past!
