Every year, Odoo releases one major (Long Term Support (LTS)) version and a few minor versions. Minor versions are mostly used in Odoo's online SaaS service, meaning that Odoo SaaS users get early access to these features. Major version branches have names such as 12.0, 11.0, and 10.0, while minor version branches have names such as saas-12.1, saas-11.1, and saas-11.2 on GitHub. The master branch is under development and is subject to change at any time. Consequently, it is advisable not to use this for production, since it might break down your database.
