Hello, and welcome for Tuesday, October 20th, 2026.
The through-line today is reliability of rendering and caching under streaming and pre-rendering, with a steady refactor to separate the App Router from live HTTP objects.
First, that decoupling effort. Several changes carry data explicitly into rendering instead of reading it off the request or response. That includes passing request headers into request stores in pull request 100333, and carrying the interception capability through route matching in 100409, plus staged fallback…
Second, cache correctness during streaming. Pull request 100448 fixes revalidations queued while a response is still streaming. Previously the flush happened before the body finished, so late tag invalidations could be dropped and late background work missed wait-until coverage. A companion proposal, 100447,…
Third, control and speed. Merged change 99871 adds new link prefetch options, including navigation, to force prefetching past an await navigation boundary when you are confident the user will click. On performance, change 100384 lazily loads React for proxy builds, cutting cold startup by about a quarter and roughly…
What's next to watch is whether…
