4.1.38 (October 31, 2026)

• Emulated Chromium needs no flag, extension dev --browser=chromium-emulator opens the emulated browser on its own now that the engine is public, and names the engine origin when it cannot be reached instead of opening a dead page
• The wasm budget reads the surface that fetches the file, a .wasm reached only by pages and workers gets the 32 MiB budget while one a content script or the service worker reaches keeps 1 MiB and still warns, and perfBudgets.ignore excuses any asset by its output path or a glob
