This release focuses on making preview environments easier to use and more predictable when you are reviewing changes in a pull request.
Smoother preview environments
Preview builds now consistently use the intended backend, which helps avoid cases where a preview loads but cannot fetch the right configuration.
This makes it easier to validate changes in a live preview without needing reruns or workarounds when the preview is first created.
Preview auth behavior updated
Authentication in preview deployments is now intentionally limited to email and password. Social sign-in options are disabled in previews, and email verification is not required there, so testers can sign in without extra steps.
