Comparing Odoo 15 and Odoo 16: Key Differences and Features

Odoo 16, released in October 2022, was a speed and polish release: a faster interface, stronger eCommerce, sales and CRM tooling, accounting and invoicing improvements, and deeper automation. Its three years of standard support ended in September 2025. Odoo's support table now shows Odoo 15 and Odoo 16 as unsupported on Odoo Online, with paid extended support on Odoo.sh and on-premise covering helpdesk and bug fixes but not security updates. For most readers the question is therefore not 15 versus 16 but how to reach a supported release — Odoo 17, 18 or Odoo 19.
