Description

The file v4-migration.md is missing although the link to it is present on the page https://www.npmjs.com/package/@azure/msal-browser

In the new version, the navigateToLoginRequestUrl option in BrowserAuthOptions is no longer available. I was actually looking for the documentation to find out what the alternative is

It seems that all v5 related things are still on v5 branch and not the default branch.

• https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/msal-v5/lib/msal-browser/docs/v4-migration.md
• also link to the changelog for the people wondering where it is too https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/msal-v5/lib/msal-browser/CHANGELOG.md

Is version 5 stable or still in beta or something? 🤔
