A three-part stack from Luke Sandberg is the core. The first layer, PR 99645, stops failed task restores from leaking pins and cache entries after a missing task error. The second, PR 99646, turns reads of collected tasks from panics into ordinary errors, whether the task is softly deleted or already evicted. The…
Second theme is better tooling for agents and memory debugging. Merged work in PR 98546 extends the trace server protocol with allocation counts, self versus subtree memory, and a heaviest span marker, while making search recursive with depth and page controls to cut round trips. Paired with a proposal to ship…
Finally, a set of user-facing papercuts. PR 99636 addresses shared stylesheets disappearing after client navigation when a page and a persistent dynamic component import the same CSS in the Pages Router on webpack, a regression from an earlier fix. Other open fixes cover custom page extensions in the no-raw-link…
