<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I’m happy to be able to report that I committed the PR for <a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/12009" target="_blank">https://core.trac.wordpress.org/ticket/12009</a> yesterday, closing a 13 year old ticket. This is a big milestone for the team, thank you to everyone who contributed to get this across the line. I know that there is still a desire to extend support to inline scripts, so I’ve opened a new ticket (<a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/58632" target="_blank">https://core.trac.wordpress.org/ticket/58632</a>) for that discussion.</li>
<li><a href="https://profiles.wordpress.org/10upsimon/" class="mention"><span class="mentions-prefix">@</span>10upsimon</a> is drafting a dev-note for this change, which we can hopefully post in the next few weeks.</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> I had people asking me questions about module support. – <a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/56313" target="_blank">https://core.trac.wordpress.org/ticket/56313</a> I wonder if this should be something we look into for WP 6.4
<ul>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Seems like the logical next step. Would be nice to do in coordination with packages from Gutenberg that want to make use of it.</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Yeah I know the folks working on the new interactivity API were quite interested in this one</li>
<li><a href="https://profiles.wordpress.org/clarkeemily/" class="mention"><span class="mentions-prefix">@</span>clarkeemily</a> let’s look at adding this to our roadmap in a future chat</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> The important thing about this functionality is the developer communication. We need a great dev note, with easy to understand and copy and paste implementations. We will also have to show developers how we can make the change and be backwards compatible.</li>

<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Excited to share that yesterday we landed <code>fetchpriority="high"</code> support: <a rel="noreferrer noopener" href="https://core.trac.wordpress.org/changeset/56037" target="_blank">https://core.trac.wordpress.org/changeset/56037</a>
<ul>
<li>That commit includes notable refactoring to make the logic that was previously scoped to only lazy-loading more broadly available, as it is also required for <code>fetchpriority</code></li>
</ul>
<ul>
<li>So with that refactoring it also unblocks a fix to another issue that still needs to be addressed with lazy-loading: <a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/58635" target="_blank">https://core.trac.wordpress.org/ticket/58635</a></li>
<li>I’m planning to work on dev notes for these changes. Still thinking through whether it should be two individual dev notes or a single one. While they are separate topics, they are deeply intertwined, and especially with the refactoring it may be a lot of repetition to have two separate posts
<ul>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I think a single dev note would be good</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> One dev note for image related changes.</li>

<li><a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/21938#comment:31" target="_blank">#21938</a> has been re-opened with the performance focus added, the e2e tests are indicating a potential performance regression that needs testing in different browsers and configurations</li>
<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> Ah yes ^ . Some of you might have seen the core and Gutenberg e2e tests are flakier than usual at the moment and it may be due to the <code>no-store</code> cache header directive that was added last week. I’ve reopened the ticket and added the performance focus, if anyone has time to do some testing that would be greatly appreciated.</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I remember looking at this last week when I opened the bug ticket about the E2E tests, and I was not convinced that the failures were related to that change, so this might be a red herring. I recall seeing several instances of network timeouts showing up prior to that change.</li>
<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> I agree it could be a red herring, but git bisect does point to that commit, so I’m honestly not sure. Although the core e2e tests did start failing before that commit, so..</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I think we can certainly try revering that change to see if the tests stop failing. Are there other steps to take to try and debug this issue?</li>
<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> I added some testing steps in a comment on the ticket, I don’t have much else at the moment</li>
</ul>
</li>
<li><a href="https://profiles.wordpress.org/westonruter/" class="mention"><span class="mentions-prefix">@</span>westonruter</a> On another front, I believe I’ve addressed the last code review for optimizing the emoji loader. Final reviews/testing appreciated so I can commit in the next hour: <a rel="noreferrer noopener" href="https://github.com/WordPress/wordpress-develop/pull/4562" target="_blank">https://github.com/WordPress/wordpress-develop/pull/4562</a></li>
