Note: whenever you change version, you have to add a record in changelog.rst The version number in the module manifest should be the Odoo major version (e.g. 8.0) followed by the module x.y.z version numbers. For example, 8.0.1.0.0 is expected for the first release of an 8.0 module. The x.y.z version numbers follow the semantics breaking.feature.fix: • x increments when the data model or the views had significant changes. Data migration might be needed, or depending modules might be affected. • y increments when non-breaking new features are added. A module upgrade will probably be needed. • z increments when bugfixes were made. Usually, a server restart is needed for the fixes to be made available. If applicable, breaking changes are expected to include instructions or scripts to perform the migration on current installations. If a module ported to different odoo versions (e.g. 8 and 9) and some update is added only to one version (e.g. 9), then the version is changed as in the example below: • init – 8.0.1.0.0 – 9.0.1.0.0 • feature added to 8.0 and ported to 9.0 – 8.0.1.1.0 – 9.0.1.1.0 • feature added to 9.0 only and not going to be ported to 8.0: – 8.0.1.1.0 – 9.0.1.2.0 • fix made in 9.0 only and not going to be ported to 8.0: – 8.0.1.1.0 – 9.0.1.2.1 • fix made in 8.0 and ported to 9.0 – 8.0.1.2.2 – 9.0.1.2.2 i.e. two module branches cannot have same versions with a different meaning |
