# Changelog Oct 29, 2021

## Next.js authentication at the edge

Our big launch this week is our new [Next.js authentication](https://clerk.com/nextjs-authentication) library that supports sub-millisecond authentication at the edge. This was the culmination of a multi-month project cutting across two teams and we couldn't be happier with the result.

We'll be continuing to improve our Next.js support throughout the end of the year, including first-class support for server-side rendering and React's new Server Components.

## Magic link bug fixes

This week we also launched many bug fixes to our upcoming [magic link functionality](https://clerk.com/blog/magic-links.md). We have updated our own sign-up form to use magic links instead of one-time passwords sent by email, and we expect to make magic links the default for all new applications soon.
