• restores router.history in the public API or router-core
• restores usePrompt block / unblock behavior

@tombuntus is attempting to deploy a commit to the Tanstack Team on Vercel.

A member of the Team first needs to authorize it.

My bad, it needs a bit more. This line needs to go away and just use the routers property

router/packages/router-core/src/router.ts

Line 413 in 3d284a6

let history = userOptions?.history || createDefaultHistory()

and also anything referencing that let variable will need to be updated as well.

@tannerlinsley I missed that! If I've understood correctly, this should be good now.
