• Reminder that BetaBeta A pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. 1 for WordPress 6.5 is scheduled for Tuesday February 13

  this ->  https://github.com/WordPress/wordpress-develop/pull/5295/commits/e69cc40698b103ad9ce330d94b6491cc9b9e362c It was a less complex solution with little chance of BC issue
• @joemcgill My feeling is that this solves such a narrow problem, that the chance of regressionregression A software bug that breaks or degrades something that previously worked. Regressions are often treated as critical bugs or blockers. Recent regressions may be given higher priorities. A "3.6 regression" would be a bug in 3.6 that worked as intended in 3.5. is not worth the benefit until there is consensus on the approach and there is some time for this to soak in coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.. I’ll leave feedback on the ticketticket Created for both bug reports and feature development on the bug tracker..

JavaScriptJavaScript JavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers. WordPress makes extensive use of JS for a better user experience. While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/. & CSSCSS Cascading Style Sheets.

• Projects from the 2024 roadmap:
  • INP opportunities research
  • Interactivity APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways.
  • Speculative prerendering

Notes from today’s meeting:

• @westonruter For Interactivity API, I’ve continued providing feedback for the pull request that adds server-side processing of directives. It’s almost there! This will be great because it will mean that client-side JSJS JavaScript, a web scripting language typically executed in the browser. Often used for advanced user interfaces and behaviors. will have to do less, resulting in better metrics likely for LCP, CLS, and INP.
• @adamsilverstein I have been working on researching INP opportunities using httparchive queries in a colab which I plan to summarize in a doc to share with the team. I have made good progress and hope to have a summary to share next week.
• @westonruter Also I identified an issue where passive event listeners can’t currently be added via event directives
• @thelovekesh https://github.com/WordPress/performance/pull/556 is ready for final review. Also as mentioned by @joemcgill to release this module as standalone pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party, @westonruter has made some changes to PR base.
