What do version numbers stand for?

Versioning allows us to assign a unique code to a version of the application. This code is used to identify the different types of evolutions of the application.

We use the versioning model W.X.Y.Z :

• W: Major software version (complete redesign of the solution and/or change of technology)
• X: Minor version of the software with significant evolution of the interface
• Y: Minor version of the software (only functional evolutions)
• Z: Revision of the previous version (corrective version)
