  • @spacedmonkey
  • @mukesh27 I’ve been working on issue #22192 and have received some feedback related to backward compatibility on the PR. I’m now in need of feedback from Joe and Felix
  • @thekt12 #58319 completed (about to be committed)
  • @thekt12 #58196 in progress, planning to give for initial review tomorrow
  • @joemcgill I made good progress on #57789 yesterday and could use a second set of eyes. It doesn’t full solve the issue of making Theme.jsonJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. data persistent, but is a step in that direction, which reduces unnecessary recalculation of that data during a page load. I’m going to work on a parallel PR to the GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ repo to get some testing of the strategy in the 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 prior to making the change in coreCore Core is the set of software required to run WordPress.

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.

  • @flixos90 Last week I spent some time conducting field analyses to assess the performance impact of the WordPress 6.3 release. Primarily focusing on Web Vitals metric LCP which measures load time performance, and how it’s affected both in general, but also specifically by the two major enhancements that were projected to affect LCP:
    • the emoji loader script optimizations
    • the lazy-loading plus fetchpriority improvements
  • Sharing the most important highlights:
    • Overall, the Largest Contentful Paint (LCP) passing rate has improved by 5.6% for classic theme sites and by 2.7% for blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. theme sites :tada:
    • The Largest Contentful Paint (LCP) boost for classic theme sites using the emoji loader script is 3.4% to 7% higher than for those that don’t use it, and for block themes it’s 0.7% to 4.5% better as well :tada:
    • When looking at only the sites where that is the case and which were still lazy-loading the LCP image with WordPress 6.2, the LCP performance impact amounts to a massive 16% to 21% improvement for mobile viewports and 6% to 9% on desktop. :tada:
    • Lazy-loading accuracy has notably improved: In WordPress 6.3, only 9-10% of sites still lazy-load their LCP image for classic theme sites (down from 27-28% in 6.2) while for block theme sites it’s 5-8% (down from 17-29% in 6.2) :tada:
  • @flixos90 drafted and published the Analyzing the Core Web Vitals performance impact of WordPress 6.3 in the field post
  • @joemcgill Nothing new from me this week, but we expect to do an initial round of benchmarks against WP 6.4 beta1 after it’s released next week.

  • @joemcgill I wanted to mention that we should probably prepare some time after beta1 next week for some initial triagetriage The act of evaluating and sorting bug reports, in order to decide priority, severity, and other factors. of any performance issues we see after the first round of code syncing from the Gutenberg project has occurred.
  • @spacedmonkey I would like to start a tracking ticket for dev notesdev note Each important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase. this team is going to work on
    • Created https://github.com/WordPress/performance/issues/840 for tracking 6.4 Trac tickets that require dev notes
