Explanation of the Versions

The development of OpenERP follows two distinct branches:

• Stable: a new version is published every year. This version is intended to be put in production, only bugfixes are applied in this version.

• Development (sometimes called the trunk): It will contain all the latest functionalities and modules. It is intended for testing purpose only, until it is stabilized as the next stable version.

You can get more information on how we manage each version in the community process .
