What's New

Optimized middleware bookkeeping and standardized pathname handling for server routes.

New Features

  • Performance optimization for middleware processing
  • Consistent pathname handling between matching and handlers

Improvements

  • Skip middleware bookkeeping when no middleware is configured
  • Stop copying serialization adapters when none are added
  • Updated @tanstack/router-core to 1.171.37

Upgrade Notes

Server route handlers and middleware now receive the router's decoded pathname, ensuring consistency with matching logic. Encoded characters like `%2F` and `%3F` are preserved to maintain the original URL structure.
