During October 2025, Ellatrix enhanced the WordPress/wordpress-develop repository by integrating Gutenberg RC2, introducing new editor blocks, and implementing dual script and module packaging to optimize front-end asset loading. They improved template management through REST API endpoints and refined slug handling for wp_template post types, addressing activation and creation flows. Their work included extending KSES sanitization to support MathML, enabling safe mathematical content rendering, and establishing global typography inheritance. Using JavaScript, PHP, and React, Ellatrix aligned versioning for the 6.9 beta cycle and stabilized build processes. The engineering demonstrated depth in backend, editor, and release management within WordPress development.
