What was accomplished

• amp-img SSR work is almost done, cleaning up the code now before creating CL
• Bento Reviews for Context and Styles
• TC39: logical assignment operators will be in ES2021
• Merged protocol-adapters for amp-list, amp-script[nodom] (Implement protocol adapters amphtml#29329, protocol adapters: e2e test, nodom binary, and bump worker-dom. amphtml#29541)
• "nodom" binary for worker-dom (Introduce "nodom" binary worker-dom#882)
• Investigating 1% ads query regression in intersect-resources and created another candidate fix

Lessons learned

• For changes that may affect ads, start minimal and incrementally diverge instead of starting with a big refactor and paring down

What's next

• Auto-envelope pattern for Bento binaries
