Understanding Odoo releases

When deploying an Odoo system, it is important to understand the various Odoo versions, as well as the release and upgrade policies. There is currently one major release for versions 6.0, 7.0, and 8.0, as well as a master branch that is the latest development version which will soon become Odoo Version 9.0. The stable versions are the standard support version of Odoo and, typically, the one you should choose to install for most situations. The master version is the development version and will often contain bugs and unfinished features. This is primarily downloaded by developers or those who wish to get a look at the latest features.
