Good morning, it's October 8th, 2026.

The big signal today is stability across deployments — making cached work reusable between builds, while pulling upgrade tooling out of core framework code.

First, durable cache. Three changes tackle why remote cache entries missed when they shouldn't. Pull request 99898 stops including execution layer and unstable module identifiers in path and code hashes, which previously split entries between app pages and route handlers even in the same deployment. Pull request…

Second, upgrade tooling is being decoupled. Pull requests 99860, 99874 and 99875 move version checks, terminal reminders and agent reminders into a dedicated upgrade package, leaving the main command as a lightweight launcher. A related eval rebuild focuses grading on the app an agent actually delivers, and pull…

Third, less noise from build and test infra. Turbopack now reports an actionable error when Node workers can't connect, common in locked-down sandboxes, in pull request 99887, and merged change 99823 downgrades filesystem cache shutdown failures to warnings. Deploy testing was reverted to lower concurrency after…

What's next: watch whether the cross-layer cache test gets…
