@pbearne the https://github.com/WordPress/wordpress-develop/pull/6994 first draft done, needs a looking at
@joemcgill We already have a good number of performance focus tickets on the 6.7 milestone—most of which are roll-overs from 6.6. I know that I need to review and clean up the ones that I’m responsible for, but I would encourage us all to do so.

@westonruter For Embed Optimizer, this PR will be ready for review this morning. I just need to add the description to detail the changes: https://github.com/WordPress/performance/pull/1302
- This includes fundamental enhancements to Optimization Detective to make it much more powerful to be able to make optimizations to a document (e.g. what Embed Optimizer requires)
@westonruter I think the plugin with the most need is Modern Image Formats as there are a couple bugs needing to be fixed: https://github.com/WordPress/performance/milestone/59
- @westonruter just merged one of the fixes
- @adamsilverstein @mukesh27 and @joemcgill are reviewing
@mukesh27 the updated sizes feature from auto-sizes is ready for this release, some final PRs ready for review:
- PR #1335 – Plugin rename
- PR #1329 – Merge feature branch to trunk
@joemcgill there’s also a proposed name change for the Auto-Sizes plugin

@joemcgill The template loading work is mainly wrapped up in 6.6. There are a few minor follow-up issues that I think we’ll continue to track but I’ll work on summarizing next steps and closing up those GH issues.
- The two things that are on my mind in the short term are:
  - Supporting the Plugin Check project as the Plugin Review team are working to get it integrated into their systems.
  - Improving our performance metrics for both Core and GB.

@joemcgill For Plugin Check, I’d like to get more eyes on this conversation., which may end up being a requirement for them to do the integration

@mukesh27 Do we have any open issue for Improving our performance metrics for both Core and GB
@joemcgill raised that @swissspidy mentioned one last week that included both misc improvements and shared performance tooling and asked about whether we should separate these issues https://github.com/WordPress/performance/issues/1093
- I do think it would serve us well to put some focus on this early in the 6.7 cycle so we can more easily pinpoint which commits have server timing performance implications. That’s been a big challenge the past 2 releases. (In the GB repo specifically)
@pbearne I am thinking of suggesting that WP has an infrastructure release where we update/re-organize the PHPUnit tests etc. as without core committers actively making the changes it will never get done. The performance testing could be part of this
- @joemcgill I would suggest proposing the infrastructure changes you have in mind and whether those become a release focus or not, could be secondary.
