timneutkens · 2021-06-14T10:14:50Z

Enables excludeDefaultMomentLocales by default
Adds distDir cleaning (See RFC [RFC] cleaning distDir on next build #6009)
Adds support for PORT (See Added support for process.env.PORT #11408)
Removes router.events from the server-side router as it should not be used server-side (long-standing todo that is potentially breaking). Note that it's still available as Router.events (import Router from 'next/router') and with useRouter in useEffect. Using it with useEffect is the correct way and I've updated the upgrading guide to reflect that
Added webpack 5 to the upgrading guide
Removed Head.rewind as it's been a no-op since Next.js 9.5 and can now be safely removed from user code

- Enables excludeDefaultMomentLocales by default - Adds distDir cleaning (See RFC vercel#6009) - Removes `router.router.events` (never documented) - Removes `router.events` from the server-side router as it should not be used server-side (long-standing todo that is potentially breaking). Note that it's still available as `Router.events` (import Router from 'next/router') and with `useRouter` in `useEffect`. Using it with `useEffect` is the correct way and I've updated the upgrading guide to reflect that - Added webpack 5 to the upgrading guide - Removed Head.rewind as it's been a no-op since Next.js 9.5 and can now be safely removed from user code
