Good morning, it's Monday, October 5th, 2026.

The lead pattern today is correctness under edge cases, with the highest user impact from an App Router refresh fix for intercepted routes.

First, parallel route state. Pull request 99663 tracks the Next URL header that was current when a refresh was scheduled, and reuses that saved value when refreshing reused parallel route slots, including through history navigation and request deduplication. That matters when an interceptable page is loaded directly…

Second, Turbopack runtime hygiene, with three connected PRs from the same author. Pull request 99671 simplifies how the shared hot module replacement runtime instantiates modules, removing layered callbacks and closures in favor of passing the module and factory directly. Pull request 99670 expands type-checking to…

In smaller but notable work, pull request 99655 normalizes thrown symbols to avoid a secondary type error, and pull request 99654 prioritizes incremental static regeneration cache control over custom app headers. Two new regression tests document currently broken cache components behavior around deep import stack…

What's next to watch is review on the parallel refresh fix, and…
