Today's biggest signal isn't one headline fix — it's a cluster of five separate navigation bugs, all fixed by the same contributor, all involving state that gets stuck between client and server.
Start with cache components. PR 98088 fixes a case where clicking a link into a fully dynamic route that calls redirect never actually navigated — it just spun. PR 98087 fixes a related problem: a stalled RSC request could poison the back-forward cache, so later clicks on that route silently did nothing until the…
Second theme: cache handler correctness. PR 98039, paired with commit 00b2275, rewrites the documented contract for custom cache handlers after discovering the example code itself could lock a stream and crash a page. PR 98098 and 98049 followed up by making test cache handlers actually forward expiration and soft…
Third theme: Turbopack scaling. PR 98093 shards a single lock that was reportedly blocking over half of thread time on a 166-thread build. PR 98090 replaces a task storage map with dense, chunked storage for better memory locality. And PR 98091 removes an unnecessary caching boundary called 223,000 times…
