    • 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. for this release were discussed

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. in spite of the improvements we’ve made. So far, I haven’t found a clear cause or opportunity to avoid the regression but am continuing to look. More eyes would be helpful for sure.

  • @johnbillion What’s the process for adding the [Focus] ... label to an issue? Is that for categorisation or only for issues that are an active focus for each team?
    • @flixos90 It’s categorization primarily. We have never had anything (at least as far as I remember) that didn’t fit in one of the existing focus groups
    • @joemcgill I believe that they used to align to the original project boards that were set up on the repo, which have evolved over the past few years, so they probably need a refresh at some point. Currently, I agree we’re not really using them for any reason

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 and it looks like we’ve mostly recovered from the regressions that were previously discovered, but we’ll take new benchmarks after Beta 1 is released today

Notes from today’s meeting:

  • @joemcgill Nothing specific to report against those milestones. Now that we’re getting into the part of the release cycle where we’ll be doing lots of benchmarks, I suspect we’ll identify some opportunities to streamline things a bit. I also think that @oandregal was working on some improvements to the GB tests that would have caught some regressions that were not caught until after the sync. I’d be curious to know if there are ways we can support that work for the future?

  • Suggestion from @joemcgill and @swissspidy to rethink the structure of the chat to align with the Core Dev Chat
    • For the past couple of weeks, the Core Dev-chat has attempted to spend more time synchronously discussing a proposal or pending issue, and having most updates linked in the agenda with the expectation that folks are reading the information ahead of the meeting. So far, it’s led to more engaging chats. Perhaps there are ways to do something similar here?
  • @clarkeemily is away on holiday next week, so @joemcgill will run the chat

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.

While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/. & CSSCSS Cascading Style Sheets.

Notes from today’s meeting:

  • @thelovekesh I have continue the work on https://github.com/WordPress/performance/pull/556 and addressed most of the feedback
  • @westonruter Regarding Interactivity API, I shared this a few days in brief, but excited to share a preemptive INP win for WordPress 6.5: I found an issue where there was a long task occurring during page load (or whenever interactive blocks are hydrated), especially when there is not a trivial number of interactive blocks on the page (e.g. 20). (Recall that any image 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. with lightbox behavior is an interactive block now.) When profiling with 6x CPU throttling the hydration was causing a 300+ ms long task. I opened a pull request to fix this by yielding to the main thread between hydration of each interactive block. It should be included in WP 6.5 with the initial public availability of the Interactivity API.
    • I have another pull request open which will defer hydration of interactive blocks until the node nears the viewport. This will require more iteration with 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/ team and won’t be part of WP 6.5, but it’s another promising performance improvement.
    • This one still needs another review: https://github.com/WordPress/performance/pull/952

Notes from today’s meeting:

  • @westonruter For Image Loading Optimization, @thelovekesh has been working on getting a Webpack build process in place to ensure there is a local copy of web-vitals.js. It is now merged. This is related to his work on Partytown
  • @westonruter Regarding sizes, I was doing some research yesterday on how well (or not) the sizes attribute is used in WordPress… The Web Almanac has a section on sizes from 2022 that shows it is a problem, but doesn’t single out WordPress specifically. I re-ran the query for determining problematic usage with sizes limited to WordPress, and compared December 2022 with December 2023, and the problem is getting worse. I’m hoping to share more specific numbers this week.
  • @adamsilverstein AVIF ticketticket Created for both bug reports and feature development on the bug tracker. if anyone wants to test or review the PR – https://core.trac.wordpress.org/ticket/51228 with AVIF support now in Edge stable, I marked this for commit

Notes from today’s call:

Notes from today’s call:

  • @joemcgill Still need to look into the failures on the 6.4 branchbranch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch". #60127
