Good morning, it's Sunday, November 8th, 2026.
The clear pattern today is making Cache Components reliable in production while cutting memory and JavaScript weight.
First, serving reliability. Three fixes target requests that previously hung, crashed or looped. Proposal 101357 addresses navigations that missed a custom cache under next start, which served an incomplete server response and crashed the client, and proposal 101356 fixes on-demand prerenders that never answered…
Second, a coordinated memory and bundle diet. Three linked proposals from Timer, 101360, 101361 and 101362, move per-request state and functions out of long-lived memory to reduce pressure on garbage collection. On the client, proposals 101352, 101353, 101354 and 101368 strip server constants, route sorting,…
Finally, correctness and security. Proposal 101369 fixes image remote pattern matching so a single-star wildcard stays within one domain label, closing an allow-list bypass where a trusted pattern could match an attacker host. Proposal 101355 ensures calling not-found shows the not-found page's title, not the stale…
What's next: if you use hostname wildcards, review your image config, verify not-found titles…
