7x Releases Exponential Basic 2.4.0.3: Extension Modules, Admin UI Refresh, and PHP 8 Hardening
August 18, 2026
Overview
7x today announced the release of Exponential Basic 2.4.0.3, the latest version of the open-source, PHP 8-ready eZ Publish 2 kernel upgrade. This release completes the extension-module API, ships the first fully working sample extension with database storage, and hardens the admin interface and core modules for production use.
Exponential Basic is 7x's long-running project to preserve and modernise the eZ Publish 2 codebase, bringing the proven community-building and personal-home-page CMS engine to PHP 8.1 - 8.3. With 2.4.0.3, developers can now build and activate new modules, admin views and database-backed features without touching the core application files.
