Standard and Performance-tier apps begin migrating to Router 2.0

Change effective on 10 July 2025

We are beginning the migration of Standard and Performance-tier applications to Router 2.0. This is a continuation of our efforts to roll out the new router across all Common Runtime apps.

Please check out Tips & Tricks for Migrating to Router 2.0 for general migration information and for details on how to migrate your apps if you’d like to beat the automatic roll-out. To our Puma users, make sure to check out Pumas, Routers & Keepalives—Oh my! for information on ensuring the best performance while using the new router.

For your convenience, you can downgrade Standard and Performance-tier apps to the legacy router by disabling the http-routing-2-dot-0 feature flag.

Check out the Legacy Router end-of-life FAQ for updates on the migration timeline and the Router 2.0 article for more details on the new router’s capabilities.
