Odoo 18 was released in October 2024 and is one of the most significant upgrades in a long time. New frontend architecture, AI features in Enterprise, and improved performance throughout the system.
New web interface architecture
The frontend has been rewritten with OWL 2 (Odoo's JavaScript framework). Faster rendering, better state management, and a more modern developer experience. Most noticeable in the backend interface: list view, form view, and Kanban load faster.
Website Builder
The drag-and-drop editor has new blocks, better responsiveness, and improved preview. Image handling is smarter with automatic WebP conversion and suggested crops. It's approaching the level of dedicated website builders.
Improved POS
The Point of Sale system has an entirely new interface. Faster, cleaner, and it works offline more reliably. Product search is lightning-fast even with thousands of items.
Spreadsheet in backend
Built-in spreadsheets that can pull data directly from Odoo models. Pivot tables, charts, and reports without exporting to Excel. It doesn't replace Excel for complex analysis, but for daily reporting it's more than sufficient.
Knowledge module
An internal knowledge base with collaborative editing (think Google Docs). Articles can be embedded in other modules: a KB article can be linked from a project task or a CRM stage. Useful for process documentation and onboarding.
Upgrading from 17 to 18 requires database migration. Test in staging. Community modules need to be checked for compatibility.
