Is there anything to be done? We could help to push it on main as the Next.JS just released v15

I have tested the canary for this with 6.0.0-canary.va0204a8 and noticed that the types for the clerkMiddleware aren't correct yet.

export default clerkMiddleware(async (auth, request) => {
  const { sessionClaims } = await auth() // auth() is not a Promise over here and causes TS and eslint to complain
  // ...
  if (!isPublicRoute(request)) {
    try { await auth.protect() } // works as expected
    catch (e) { unstable_rethrow(e) }
  }
})

Do you want me to open a separate issue to track this?
