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. 3 is today * Discussion around any WordPress 6.5 tickets [[link](https://core.trac.wordpress.org/query?status=accepted&status=assigned&status=closed&status=new&status=reopened&status=reviewing&focuses=~performance&milestone=6.5&groupdesc=1&group=resolution&col=id&col=summary&col=status&col=milestone&col=owner&col=type&col=priority&col=keywords&order=priority)] - 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 - Please check [https://github.com/orgs/WordPress/projects/154?query=is%3Aopen+sort%3Aupdated-desc](https://github.com/orgs/WordPress/projects/154?query=is%3Aopen+sort%3Aupdated-desc) for progress on all dev notes ## Priority Projects ### Server Response Time * Link to the [GitHub project board](https://github.com/orgs/WordPress/projects/112/views/1) * Contributors: [@joemcgill](https://profiles.wordpress.org/joemcgill/) [@swissspidy](https://profiles.wordpress.org/swissspidy/) [@thekt12](https://profiles.wordpress.org/thekt12/) [@mukesh27](https://profiles.wordpress.org/mukesh27/) * Projects from the 2024 roadmap: - Internationalization Performance - Improve template loading Notes from today’s meeting: * [@joemcgill](https://profiles.wordpress.org/joemcgill/) [#59532](https://core.trac.wordpress.org/ticket/59532) was fixed last week and some unit testunit test Code written to test a small piece of code or functionality within a larger application. Everything from themes to WordPress core have a series of unit tests. Also see [regression](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?output_format=md#regression). improvements were added thanks to [@thekt12](https://profiles.wordpress.org/thekt12/) * [@thekt12](https://profiles.wordpress.org/thekt12/) Working on implementing caching using transient for non-persistant cache website [#59719](https://core.trac.wordpress.org/ticket/59719) I have drafted an initial PR for just 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.

Regressions are often treated as critical bugs or [blockers](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?output_format=md#blocker). 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. * [@spacedmonkey](https://profiles.wordpress.org/spacedmonkey/) There are 1020 matches for register_block_pattern in the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

Users might say something along the lines of “Ping me when the meeting starts.” me * [@johnbillion](https://profiles.wordpress.org/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](https://profiles.wordpress.org/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](https://profiles.wordpress.org/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 **Our next chat will be held on [Tuesday, March 5, 2024 at 16:00 UTC](https://www.timeanddate.com/worldclock/fixedtime.html?iso=20240305T1600) in the [#core-performance channel](https://wordpress.slack.com/messages/core-performance/) in [Slack](https://make.wordpress.org/chat/).** [#core-performance](https://make.wordpress.org/core/tag/core-performance/), [#performance](https://make.wordpress.org/core/tag/performance/), [#performance-chat](https://make.wordpress.org/core/tag/performance-chat/), [#summary](https://make.wordpress.org/core/tag/summary/) ### Share this: * [ Threads ](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?share=threads) * [ Mastodon ](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?share=mastodon) * [ Bluesky ](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?share=bluesky) * [ X ](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?share=x) * [ Facebook ](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?share=facebook) * [ LinkedIn ](https://make.wordpress.org/core/2024/02/27/performance-chat-summary-27-february-2024/?share=linkedin) # Post navigation [← Connect with the GitHub Outreach group to request feedback or further testing. ](https://make.wordpress.org/core/2024/02/27/connect-with-the-github-outreach-group-to-request-feedback-or-further-testing/) [Summary of Hallway Hangout on overlapping problems in the Site Editor →](https://make.wordpress.org/core/2024/02/27/summary-of-hallway-hangout-on-overlapping-problems-in-the-site-editor/)
