During April 2026, work focused on enhancing the zed-industries/zed repository by implementing customizable syntax highlighting for custom JSX elements in TSX and JavaScript. This feature introduced the tag.component.jsx highlight group, enabling theme authors to apply per-element theming and targeted color customization while maintaining compatibility with existing themes. The approach aligned highlighting strategies with patterns used in other languages such as Vue and Svelte, promoting consistency across tools. The release included support for local changes and theme overrides, with updates to documentation and release notes to clarify improved readability and extensibility for both end users and theme developers.
