Semantic versioning
Given a version number MAJOR.MINOR.PATCH, increment the:
MAJORversion when you make incompatible changesMINORversion when you add functionality in a backwards-compatible mannerPATCHversion when you make backwards-compatible bug fixes
Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
Pre-release labels
These labels will be taken from the Government Digital Services development process stages, and will be one of:
Discovery: A Feasibility study. A 'No code' development. Designed to find out what users are trying to achieve, any constraints, improvement opportunities.
Alpha: Develop prototypes and test with users. Could be minimal functionality and potentially prototypes for any options to determine which is best.
Private Beta: Working version and test with invited users. Handle real transactions and work at scale. ‘Invite only’ or regional. Must Pass assessment by business and technical SMEs.
Public Beta: All users can participate. Version unlikely to change substantially, but still needs further testing by a wider group of implementers before becoming live.
Live: The live phase is about supporting the service in a sustainable way, and continuing to iterate and make improvements.
Retiring: Implementers notified that the service is discontinued and not to be used for new developments.
