[jridgewell]

What was accomplished

• Release duty, with multiple cherry picks
• A few validator PRs to support amp-img SSR

Lessons learned

• Release duty is getting easier

What's next

• Finishing amp-img SSR validator support, building Google Cache's SSR
• Reviewing Bento PRs, and working on Bento externs

[dreamofabear]

What was accomplished

• Fixed bug that cause some ads not to render when some extension scripts are duped ( amphtml#29042)
• Fix element relayout bug in intersect-resources ( amphtml#29048)
• Enable intersect-resources in 100% of prod (rolls out on 7/14)

Lessons learned

• Strong runtime assumptions about AMP validity (e.g. no dupe extension scripts) are increasingly problematic

What's next

• Keep an eye on intersect-resources prod rollout

[samouri]

What was accomplished

• Submitted a fix for rrule that was a long time coming  amphtml#28887
• Design review for AMP.goBack. Just a couple tees to cross and it should be good to go.
• Emit custom metrics from performance-impl so that we can more easily take advantage of those metrics in gulp performance.

Lessons learned

• dispatching custom events can be slow.

What's next

• RTV Experiment for compiling v0/extensions in strict mode.
• Creating a client side experiment for removing calcTaskTimeout logic as well as manually measuring the perf impact for the specific use case involved (prioritizing 1vp elements when overloaded/stress tested)
• Figure out the state of ie11 integ testing/if still useful to make the the test for minimum support in most common components
