### Fixes

- **Source build portability:** keep tsdown configuration self-contained so builds do not depend on resolving the tsdown package from unrun's temporary module directory.

- **Diffs rendering:** render viewer and image output from one SSR preload, preserve language-pack highlighting through hydration, normalize language hints case-insensitively, skip identical before/after inputs with an explicit `changed` result, report truthful file-render and input errors, cache hash-pinned viewer runtimes, and prefer canonical file settings over stale aliases. (#100487)

- **Remote browser reliability:** bound persistent Playwright tab enumeration by the existing remote CDP timeout budget and retire timed-out connection attempts so late completions cannot restore a stuck connection. (#80147, #58968) Thanks @HemantSudarshan and @KeaneYan.

- **Managed browser cookie persistence:** initialize new isolated macOS headless profiles with a non-interactive encryption key while preserving existing profile keys, and close Chromium through CDP before bounded signal fallback so persistent logins survive graceful browser and Gateway restarts. (#96704, #98284) Thanks @TurboTheTurtle.

- **TUI new-session hooks:** create `/new` sessions through the shared Gateway lifecycle so command and session hooks receive the completed parent transcript in both Gateway and embedded modes, while preventing rollover during an active turn. (#100241, #49918) Thanks @BingqingLyu.

- **TUI abort diagnostics:** show sanitized tool argument-validation summaries for aborted runs in both Gateway and local TUI modes without exposing raw model arguments. (#91002) Thanks @wsyjh8.

- **iOS Watch replies:** persist queued quick replies in the gateway-scoped chat outbox and submit them through idempotent chat delivery, preventing losses, duplicates, and cross-gateway sends after reconnects. (#100031) Thanks @NianJiuZst.
