   - RPM `chrome-sandbox` SUID via `%attr(4755, ...)` instead of a `%post` chmod scriptlet so the bit survives `--noscripts` and layered images (#539)
   - `autoUpdater` no-op Proxy on Linux that defends against future feed activation, with a thenable allowlist masking `then`/`catch`/`finally`/`Symbol.toPrimitive`/`Symbol.iterator` to `undefined` (#567)
   - Failing loudly on `npm install node-pty` failures instead of silently shipping the upstream Windows binaries, plus auto-installing `gcc`/`g++`/`make`/`python3` on minimal build environments (#401)
+- **[Hayao0819](https://github.com/Hayao0819)** for diagnosing the upstream `titleBarStyle:""` → `titleBarStyle:"hiddenInset"` migration that broke the About window render on GNOME/X11 and contributing the `isPopupWindow()` match extension (#481, #489)
