<li><strong>WordCamp Europe contributor day</strong> was a great success – thank you to those who joined!
<ul>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> On my side we were working on the script loading strategy API, testing the PR <a rel="noreferrer noopener" href="https://github.com/WordPress/wordpress-develop/pull/4391" target="_blank">https://github.com/WordPress/wordpress-develop/pull/4391</a> by modifying some plugins and core code to use it. We also discussed how it works and were able to find a few nuances and little bugs that were fixed</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> we onboarded a number of contributors to profiling / benchmarking</li>
</ul>
</li>
<li>Release 2.4.0 scheduled for Monday June 19
<ul>
<li>Agreed to <strong>postpone this to Tuesday June 20 </strong>to support several team members being out for the US holiday</li>
</ul>
</li>
<li>Upcoming <strong>Beta 1 for the 6.3 release on Tuesday June 27, 2023</strong>
<ul>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I’m still not sure how we can best test/support the effort that is going into adding the Fonts API in 6.3. I raised the question last week in the core chat: <a rel="noreferrer noopener" href="https://wordpress.slack.com/archives/C02RQBWTW/p1686169592117799" target="_blank">https://wordpress.slack.com/archives/C02RQBWTW/p1686169592117799</a></li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a>: <a href="https://profiles.wordpress.org/hellofromtonya/" class="mention"><span class="mentions-prefix">@</span>hellofromtonya</a> shared with me last week that one of the main focuses related to the Fonts API is <a rel="noreferrer noopener" data-hasqtip="170" href="https://github.com/WordPress/gutenberg/pull/50927" target="_blank">https://github.com/WordPress/gutenberg/pull/50927</a>, which is still an early PR, but would be great to get into WP 6.3</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> There aren’t any specific tickets to sync this code to the WP repo that I could find. Does anyone else here have any more insight? Or have plans to own the performance impact research for this feature?</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> Is it mentioned here? – <a rel="noreferrer noopener" href="https://github.com/WordPress/gutenberg/issues/51077" target="_blank">https://github.com/WordPress/gutenberg/issues/51077</a></li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> This seems like the most likely ticket: <a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/46370" target="_blank">https://core.trac.wordpress.org/ticket/46370</a></li>

<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> For Script Loading Strategy: we’ve finished addressing most of the outstanding issues with the PR. Thanks to all who helped test it at Contributor Day last week. My goal right now is to get the last details wrapped up so we can get a final from the release team to get this merged. The main outstanding question that we still need to resolve is whether our approach for managing inline scripts attached to delayed script handles is acceptable. I’d like to get a second opinion from someone in <a rel="noreferrer noopener" href="https://wordpress.slack.com/archives/C5UNMSU4R" target="_blank">#core-js</a> but am not confident on who should weigh in <a rel="noreferrer noopener" href="https://github.com/WordPress/wordpress-develop/pull/4391" target="_blank">https://github.com/WordPress/wordpress-develop/pull/4391</a></li>

<ul>
<li> Somewhat unrelated, but I got a PR into jetpack that will inline block styles – <a rel="noreferrer noopener" href="https://github.com/Automattic/jetpack/pull/31214" target="_blank">https://github.com/Automattic/jetpack/pull/31214</a></li>
</ul>
</li>
<li><a href="https://profiles.wordpress.org/westonruter/" class="mention"><span class="mentions-prefix">@</span>westonruter</a> I’m working on fixing an issue with the timing for when the delayed inline script loader is added to the page. I found some cases when it is not printed at the right time (or at all). I have some refinements I’m making this morning before ready for review: <a rel="noreferrer noopener" href="https://github.com/10up/wordpress-develop/pull/75" target="_blank">https://github.com/10up/wordpress-develop/pull/75</a></li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I’d say the three issues in the “in progress” column here is what we’re trying to wrap up: <a rel="noreferrer noopener" href="https://github.com/orgs/10up/projects/14" target="_blank">https://github.com/orgs/10up/projects/14</a> is that correct?
<ul>
<li><a href="https://profiles.wordpress.org/westonruter/" class="mention"><span class="mentions-prefix">@</span>westonruter</a> I think so, yes. The last one just needs a quick review from <a href="https://profiles.wordpress.org/mukesh27/" class="mention"><span class="mentions-prefix">@</span>mukesh27</a></li>
</ul>
</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Is there already a (draft) PR for the reduced implementation?
<ul>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> There is not. That will be the next thing to work on as soon as we’ve got the ideal version ready to go</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Honestly, hoping we don’t even need it, but want to be ready to put that together in the next week so we have time for reviews before the beta 1 cutoff</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> I think the main question I’d like to sort out this week is how we will handle the fallback approach in case we don’t get any inline script handling in. I’m personally leaning towards:
<ul>
<li>change defered/async strategy to blocking if they have an <em>after</em> script</li>
<li>do not change strategy if it’s a <em>before</em> script</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Please comment on <a rel="noreferrer noopener" href="https://github.com/10up/wordpress-develop/issues/69" target="_blank">https://github.com/10up/wordpress-develop/issues/69</a> where we can work out those details. I agree with your bullet points, though</li>

<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Test coverage wasn’t added before because we needed to figure out the exact API, so writing test coverage before that would have required a bit too much extra iterations</li>
