What is the biggest change in Odoo 18?

The tree-to-list view rename is the most impactful change for developers, as it affects all custom modules. For users, the new passkey authentication and Click & Collect eCommerce features are the most visible additions.

Is Odoo 18 stable for production?

Yes. Odoo 18 was released in October 2024 and has been in production use since then. It received regular bug fix releases throughout its lifecycle and is a stable, mature release.

What testing framework does Odoo 18 use?

Odoo 18 introduces the Hoot testing framework, replacing QUnit for frontend unit tests. The new web.assets_unit_tests bundle provides the testing infrastructure. Legacy QUnit tests should be migrated to Hoot.

Can I upgrade from Odoo 17 to 18?

Yes. Key steps include renaming tree view references to list, migrating QUnit tests to Hoot, reviewing merged accounting modules (account_lock, account_payment_term, account_audit_trail), and updating web_editor customizations for the html_editor split.

OWL 2.8.1 — frontend framework upgraded from OWL 2.x in v17 to OWL 2.8.1 with performance improvements.
Hoot Testing Framework — new web.assets_unit_tests bundle replaces legacy QUnit-based testing. All frontend tests should use Hoot going forward.
