1.15.22 — WebApp routes survive address restore

2026-08-22

Taking a WebApp offline and restoring its address now keeps its custom API and path routes instead of silently rebuilding only the managed sign-in routes.

• Keeps custom routes as part of the WebApp’s durable serving configuration, independent of any one hostname.
• Automatically captures routes from apps created before this release when they first go offline or change address.
• Recreates those routes on the restored primary address before reapplying the live release.
• Revalidates every retained destination against the selected domain and tenant before changing DNS; an unsafe or retired destination produces a visible refusal instead of a partial restore.
• Continues to derive and protect hosted sign-in/account routes separately.
