Lubieowoce's PR 95384 makes synchronous I/O strictly an error outside the dynamic rendering stage, tightening a rule that was previously more permissive. Related work in PR 95596 and a same-day commit uncovered a preexisting race in how Link detects…
Third, developer experience and editor tooling saw meaningful investment. Unstubbable shipped two PRs, 95463 and 95486, that cancel superseded Server Components HMR refreshes on both client and server, avoiding wasted renders during rapid edits.
