Exponential 6.0.14 Now Available — Full MongoDB 8 Database Adapter + Critical Cross-Database ORM Fixes

7x is very pleased to announce the release of Exponential 6.0.14 to users worldwide, released on June 7, 2026. This release delivers full MongoDB 8 database adapter support — enabling the entire CMS kernel to run against MongoDB in place of MySQL, PostgreSQL, or SQLite — alongside critical cross-database ORM fixes that were silently breaking all content rendering on SQLite and PostgreSQL installations, shared-hosting MySQL setup wizard improvements, and PHP 8 compatibility hardening throughout the user and role system.

Happy 6/7 to the Exponential Community!

Key Highlights

• MongoDB 8 Database Adapter — A complete new database backend (expMongoDB) implementing eZDBInterface for MongoDB 8.x. Select MongoDB from the setup wizard, migrate an existing MySQL installation using the new bin/mongodb/ tooling, or install fresh. Connection parameters read from the standard [DatabaseSettings] block in site.ini. Full design and compatibility documentation in doc/bc/6.0/MONGODB_KERNEL_SUPPORT_EXPANSION.md.
• Shared-Hosting MySQL Setup Wizard — The setup wizard no longer requires SHOW DATABASES privilege or root access. When an explicit database name is provided the wizard connects directly to the application database using only standard per-database grants.
• Admin UI Fixes — browse.tpl integer PersistentData values no longer silently suppressed, fixing the Copy content action. js_class_languages initialised as [] not empty string. jQuery .size() replaced with .length in node_tabs.js.

Getting Started

• Download the release from GitHub or install via Composer: se7enxweb/exponential.
• MongoDB installations: read the migration guide at doc/bc/6.0/MONGODB_KERNEL_SUPPORT_EXPANSION.md before installing.
• SQLite and PostgreSQL users: this release fixes fundamental ORM breakage — upgrade is strongly recommended.
• Check exponential.earth for packages, extensions, and Composer setup instructions.
• Turnkey Exponential CMS hosting is available at se7enx.com.

Upgrade Notes

• SQLite: all content rendering was broken before this release. Upgrade immediately.
• MySQL shared hosting: no root or SHOW DATABASES privilege required.
• MongoDB: new installations select MongoDB 8 from the setup wizard. Existing MySQL installs migrate via bin/mongodb/. See known limitations in doc/bc/6.0/MONGODB_KERNEL_SUPPORT_EXPANSION.md section 26.
• jQuery: custom code using .size() must be updated to .length.
