5 open tickets still in this release milestone
@joemcgill I plan on going through these and trying to close out what we can later today. #53167 is ready for commit but I’m unsure if @adamsilverstein or @spacedmonkey are planning to take care of that one
@thekt12 New PR for #57789 will address remainder of #59600

@mukesh27 PR that ready for review:
- PR #1298 – Audit Autoloaded Options Site Health should extend Core’s check if available
@joemcgill Also worth noting that Chrome 126 is scheduled to ship today with auto-sizes support turned on, so we should be able to get better testing feedback soon from folks using that feature plugin.
- @westonruter opened https://github.com/WordPress/performance/pull/1296 in order to do a quick minor release of Optimization Detective and could use reviews

@joemcgill Made a few updates to the dev-note draft based on feedback from @peterwilsoncc yesterday. I think it’s ready to publish at this point. @pbearne will create a draft post

@thekt12 I have raised a new bug #61405 (with a POC that currently breaks some tests ). Same pattern was also observed in WP_Theme_JSON_Data::$theme_json, but I am not sure of the performance impact it will have. PR#6781 will address the remainder of #57789 and #59600 ; estimated to give at least 3% improvement.

@joemcgill This issue has been flagged as something that could use help investigating: https://github.com/WordPress/gutenberg/issues/10169
- Good suggested ticket for contributor day!
