# Prefill Sign Up & Sign In Components, Improved SAML Account Linking, and Stable Remix v2 Support

## Prefill Sign Up & Sign In Components

You are now able to prefill email address, username, and phone numbers in the `<SignUp />` and `<SignIn />` components, either by passing an initialValues prop or by using query strings. Check out [the docs](https://clerk.com/docs/components/authentication/sign-in.md#props) to learn more!

Here, we want to build session management in Next.js without using any authentication library to show you what is really happening under the hood.

## Improved SAML Account Linking

Users who exist in your account before you enable SAML can now authenticate with your IdP and link an enterprise connection to their account.

## Stable Remix v2 Support

The newly released @clerk/remix package introduces stable support for Remix v2, without the need for the V2\_ prefixes of “future-flags”. Since this is a breaking change, a major bump was needed (v3) – to get the latest version, use `npm i @clerk/remix@latest`.

## Other Fixes & Improvements

- Updated Email Blocking so that blocking an email address will also block all its subaddresses
- Added support in the [Clerk Expo Starter](https://github.com/clerkinc/clerk-expo-starter/tree/router-v2) for the file-system-based router that was introduced with Expo Router v2
