WordCamp Asia 2026 Core Committers Meeting

On April 11, 2026, CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. Committers in attendance (including emeritus) at WordCampWordCamp WordCamps are casual, locally-organized conferences covering everything related to WordPress. They're one of the places where the WordPress community comes together to teach one another what they’ve learned throughout the year and share the joy. Learn more. Asia in Mumbai, India gathered for a brief informal meeting.

There was no formal agenda, but a few goals for the meeting were mentioned at the beginning:

  • Allow newer committers to meet more senior ones.
  • Allow anyone to raise questions, concerns, or suggestions that have been on their minds.
  • Just spend some time together chatting and getting to know each other.
  • Discuss short and medium term challenges.

Below are some brief notes from discussions that happened following Chatham House Rule.

7.0 Release

The 7.0 timeline and active freeze on unrelated commits to trunk were discussed before moving on to examining the remaining open tickets in the milestone. All findings and thoughts were added publicly to each individual ticketticket Created for both bug reports and feature development on the bug tracker..

A summary of the state of the real-time collaboration feature was given so that everyone in attendance was up to speed with the approaches being evaluated and what the potential tradeoffs are. Attendees agreed to add any thoughts they had to the respective tickets and pull requests.

It was flagged that there could be some differences between how MySQLMySQL MySQL is a relational database management system. A database is a structured collection of data where content, configuration and other options are stored. https://www.mysql.com/MariaDB and SQLite work. Since Playground runs on SQLite, there could be some compatibility issues with the proposed table structures that surface. It could be helpful for SQLite support to be re-evaluated in WordPress Core to have a more firm policy around support expectations.

Code Syncing from gutenberg Repository

The new build tooling processes introduced during the 7.0 cycle through #64393 were discussed.

  • In practice, it’s not clear what this means going forward when managing multiple branches.
  • For 7.0 and trunk (at the time of the meeting), the gutenberg.sha value pinned is from the wp.7.0 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"..
  • That would remain true for the 7.0 branch, but SVNSVN Subversion, the popular version control system (VCS) by the Apache project, used by WordPress to manage changes to its codebase. trunk will be updated to pin from the upstream trunk branch after the release.

One of the benefits of these build script changes is that it’s easier to sync code maintained in 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/ repository more often. What an ideal sync schedule could look like was discussed:

  • Sync on the week following a new release of the Gutenberg 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.. This allows for any .1 and .2 releases that may be necessary to occur.
  • During 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./RCrelease candidate One of the final stages in the version release cycle, this version signals the potential to be a final release to the public. Also see alpha (beta). periods, syncing weekly or prior to each pre-release version using a SHA value from the corresponding wp/X.Y branch for the gutenberg.sha property.

This practice does have some nuance that needs to be discussed more broadly. Mainly, when SVN trunk is bumped to X.Y+1-alpha, it makes sense to also update the pinned SHA value in wordpress-develop to represent the most recent Gutenberg plugin release. While this makes sense in theory, it is counter to the current practice of “commit to trunk first, then backportbackport A port is when code from one branch (or trunk) is merged into another branch or trunk. Some changes in WordPress point releases are the result of backporting code from trunk to the release branch. to numbered branches” because there will possibly be some divergence in SVN trunk.

There is also still some code that requires the manual creation of a pull request to wordpress-develop from gutenberg, so the process is not 100% there just yet.

Ways To Improve New Build Scripts

  • There are likely ways to improve how code is imported into the wordpress-develop repo so that it lands in more appropriate locations. Examples: no adminadmin (and super admin)-facing code in wp-includes or using insertion points for various points in wordpress-develop PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher files to copy relevant chunks of code.
  • The inline documentation for the code managed in the gutenberg repository is currently lacking important elements such as @since tags.
  • There is still friction between 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-based and PHP-based functionality in this process.
  • There is more room to automate the process in general.

There was agreement that a good way to proceed would be to take inventory of what manual workflows still exist even after the recent changes to how this is managed.

Performance Team

It was noted that the Performance Team has experienced a decrease in active contributors with only a small number who are regularly active. There are currently 7-10 individual performance-focused plugins being maintained by the team.

There were two agreed upon take aways:

  • Stepping back to highlight the status and goals of each plugin could make it easier for contributors who have not yet been involved to be brought up to speed and potentially attract new contributors.
  • There are a few high-potential plugins that need coordinated effort to get them to the finish line and integrated into Core.

Looking Ahead to WordPress 7.1

The discussion transitioned from discussing those high-potential performance plugins that could possibly be ready for a merge proposal to possible targets for the 7.1 cycle more broadly. Some of the ideas brought up were:

  • Retrying client-side media (was reverted and punted from 7.0).
  • Template Organization/Management (also reverted and punted from 7.0).
  • Front-end view transitions for all users (not just logged out). Still has implementation hurdles that need broader discussion.
  • Per-template styles
  • Enhanced Responsive Images (sizes="auto" support and improved sizes attributes 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. themes).

Props @westonruter for peer review.

Performance Lab Plugin (and other performance plugins)

  • @westonruter also updated the “Tested up to” version for the Instant Back/Forward plugin, which is included among the features listed in Performance Lab. @westonruter mentioned that the “Tested up to” versions for the Performance Lab plugins still need to be updated on WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users.

Arguments used to hook both filters and actions look the same. are no longer installed automatically, so the handbook documentation was updated to mention that npm run prepare now needs to be run during the initial setup.
  • @westonruter also shared PR #2482, which fixes plugin installation and activation flows in Performance Lab when WordPress is using FTPFTP FTP is an acronym for File Transfer Protocol which is a way of moving computer files from one computer to another via the Internet.

Open Floor

  • @adamsilverstein shared a newly opened issue to explore adding AI based performance recommendations to the plugin when WordPress 7.0 is available and AI is configured #2485
    • @adamsilverstein mentioned that this may work better as a separate plugin and shared that AI has improved enough to provide genuinely useful recommendations to users and potentially even fix issues automatically. @adamsilverstein also referenced the earlier wp-performance-wizard project built two years ago, noting that it already provided good results at the time and that the new idea would likely start with a simpler approach.

            • @westonruter suggested that creating a separate “firehose” channel could be an option if the team wants to preserve visibility without overwhelming the main channel, while also noting that they are already subscribed to all issues and pull requests directly in the repository.

          Our next chat will be held on Tuesday, February 24, 2026 at 16:00 UTC in the #core-performance channel in Slack.

          WordPress Performance TracTrac An open source project by Edgewall Software that serves as a bug tracker and project management tool for WordPress. tickets

          • @westonruter shared a Trac query covering performance-related tickets milestoned for WordPress 6.9.1 and 7.0.
          • @westonruter shared that for ticketticket Created for both bug reports and feature development on the bug tracker. #61500, some work was done recently as part of the CodeMirror upgrade effort.
            • @westonruter explained that ideally there would be a declarative way to add script modules as dependencies for classic scripts, and noted that a workable approach is to register an empty script module that declares module dependencies, and then enqueue that module whenever the classic script is enqueued. @westonruter shared reference to example diffs demonstrating this workaround and mentioned being glad to find a quick solution.
          • @mukesh27 asked whether @westonruter had reviewed the latest comment on #64229, where @wildworks raised a minor point and opened a PR.
            • @westonruter replied that the comment had been seen the night before and initially mentioned not having a 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. yet, then noted that a PR already existed and shared PR #10799. @westonruter reviewed the PR, said it looked good, and approved it.
          • @westonruter brought up #64066 and shared that @gilbertococchi is actively working on collecting data to support switching to moderate prefetch by default on sites with caching.
            • @westonruter referenced a Slack thread where LCP passing rates for conservative versus moderate prefetch were discussed and noted that additional data is being gathered by flipping a few CrUX-eligible sites from conservative to moderate to compare LCP passing rates and page hit increases over time.
            • @westonruter added that landing #64066 is related to #64370, noting that the latter needs to land to ensure reliable detection.
          • @mukesh27 asked about the review status of PR #10606 and mentioned seeing comments from @westonruter.

          Performance Lab 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. (and other performance plugins)

          • @westonruter shared recent experience using GitHubGitHub GitHub is a website that offers online implementation of git repositories that can easily be shared, copied and modified by other developers. Public repositories are free to host, private repositories require a paid subscription. GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged by the repository owner. https://github.com/ Copilot together with Gemini CLICLI Command Line Interface. Terminal (Bash) in Mac, Command Prompt in Windows, or WP-CLI for WordPress. locally, describing it as immensely useful both for review and implementation work. @westonruter described Copilot as significantly better than a traditional linter during reviews and noted that it can provide strong first-pass implementations. @westonruter shared PR #10778 as an example of using Gemini CLI during the CodeMirror upgrade and explained that a detailed historical and technical specification was provided to the tool.
            • @westonruter also shared that Copilot was used to draft a Performance Lab fix while on public transit using only a phone, referencing PR #2346.
            • @dmsnell cautioned that Copilot can sometimes reintroduce defects during PR reviews, sharing an anecdote where Copilot repeatedly flagged and reintroduced a PCRE-related bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority. even after it had been fixed.
            • @justlevine added that this behavior can indicate ambiguities in code and suggested that improving self-documentation helps both humans and LLMs.
            • @dmsnell emphasized the need for extra care when LLMs introduce defects, as they can confidently repeat mistakes if the surrounding code does not change enough.
            • @westonruter agreed, noting that while hallucinations occur, the tools still provide good feedback most of the time and help shift focus away from minutiae like coding standards toward higher-level problem solving.
          • @dmsnell raised the topic of memoizing wp_normalize_path, noting observed performance improvements of roughly 1ms during WordPress startup in certain environments. @dmsnell explained that while this is a micro-optimization, it can have meaningful impact at scale and shared that @josephscott has been investigating early startup costs using production measurements. @dmsnell mentioned having tested earlier versions without caching and discussed trade-offs between caching and alternative approaches, including replacing PCRE calls and addressing what may be a latent bug.
            • @westonruter asked whether similar performance benefits were observed across different approaches.
            • @dmsnell replied that while direct testing had not yet been done for all variants, prior comparisons suggested the cache provided most of the benefit at a fraction of the cost, and that both approaches could potentially coexist.
            • @westonruter summarized this as a “both/and” situation rather than an either/or choice.

          Our next chat will be held on Tuesday, February 10, 2026 at 16:00 UTC in the #core-performance channel in Slack.

            • @westonruter highlighted #64066 as potentially the most impactful open ticketticket Created for both bug reports and feature development on the bug tracker., which proposes changing Speculative Loading’s default eagerness from conservative to moderate when caching is detected. @westonruter noted that no negative feedback has been received so far but acknowledged the change could be controversial and planned to ask for additional feedback in the #hosting channel.
          • @mukesh27 asked about the status of the Adminadmin (and super admin) View Transitions work. @westonruter replied that this is tracked in #64470, with an active PR #10699 opened by @flixos90.
            • @westonruter shared that the change looks close to being ready, but an unexpected E2E test failure still needs investigation. @mukesh27 shared that the implementation looks solid overall, and @westonruter mentioned he had merged the latest trunktrunk A directory in Subversion containing the latest development code in preparation for the next major release cycle. If you are running "trunk", then you are on the latest revision. changes and planned further debugging, including testing behavior with unminified scripts if the failure persists.
