Call for Topics for the Dev Chat agenda

@sirlouen suggested to publish the “Call for Topics for the Dev Chat agenda” earlier to give contributors more time to suggest topics. @benjamin_zekavica, speaking for the Team Reps, noted that while it can be challenging due to time constraints, they will aim to publish the Call for agenda 1–2 days in advance and update it as needed.

He supports the idea of raising topics early and will discuss improvements with the other reps. Further updates on this will follow.

In the discussion on ticketticket Created for both bug reports and feature development on the bug tracker. #63436, it was agreed that PHPCS should not be applied to the FTP class files. These files come from an old external library, and applying coding standards would only make sense if WordPress fully adopts the code. There was also agreement on the need for clearer rules and improved documentation.

Discussion 💬

CSSCSS Cascading Style Sheets. Regressions in 6.8

@luminuu reported regressions in several third-party plugins caused by bugfixes introduced in WordPress 6.8 (PR #64770). Affected projects include Jetpack and WooCommerce. One key issue—buttons stretching full width—was tracked in Trac ticket #63373 and is scheduled to be fixed in version 6.8.2.

The group discussed how to prevent similar issues in the future. Suggestions included:

  • Introducing a Dev Notedev 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. format to track frontend CSS changes per release
  • Improving visibility of such changes before they ship
  • Investing in visual 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. testing
  • Collecting and surfacing CSS-related changes in “What’s new in 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/?” posts

Better communication, testing, and transparency are needed to reduce the risk of regressions in future releases.

WordPress 6.8.1 was released right after the dev chat. It is a maintenance release.

For now, 6.8 is identified as the last major release of the year.

Forthcoming releases 🚀

WordPress 6.8.2

There are currently 7 tickets in the 6.8.2 milestone on Trac. Bugfixes currently located in milestone 6.9 can probably start to be moved to 6.8.x milestones, but 6.8.2 will most probably still be focused on remaining issues/regressions found on 6.8.

Discussion 💬

@sirlouen wanted to bring attention to this ticketticket Created for both bug reports and feature development on the bug tracker.: #43936. He commented this ticket with a recap of everything that must be known if someone doesn’t want to read all the way through. @audrasjb pointed out that this ticket is a good candidate for a further 6.8.x release, as the patchpatch A special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing. shouldn’t add any new file.

@sirlouen pointed out that publishing a call for dev chats topics should ideally be posted on the Make/CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. Slack channel, ideally 2 days before each meeting to help gather topics for the agenda. @audrasjb proposed to post such a call on next Monday and to iterate on this process.

@sirlouen added another topic coming from the Core Test Team: “I’m writing a guide on creating Testing Use-Cases for core developers. The thing is that I’ve found over the period of ~100 ticket reviews, that most old stuck tickets with patches that have been pretty much abandoned, the main cause is that the patch creator did not provide enough information to test and help patch progress (even sometimes other reviewers asked for it). I’ve been ideating some examples and ideas, to help people build testing cases, and I’m going to publish this in the Test WP blogblog (versus network, site).” He is looking for people able and willing to review his proposal. @audrasjb volunteered.

@justlevine proposed to discuss the following ticket: #62622: Bump minimum PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher version to 7.4.
This ticket is on @johnbillion‘s radar. Everyone agreed that this ticket is a major goal for 6.9.
