Guide Versioning

This is guidance is under active development. Your feedback will help us improve it.

Semantic Versioning

Given a version number MAJOR.MINOR.PATCH, increment the:

  • MAJOR version when you make incompatible changes.
  • MINOR version when you add functionality in a backwards-compatible manner,
  • PATCH version 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.

Release Labels

These labels will be taken from the GDS 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 SME’s

  • Public Beta: All users can participate. Version unlikely to change substantially, but still needs further testing by a wider group of implementors before becoming live

  • Live: The live phase is about supporting the service in a sustainable way, and continuing to iterate and make improvements

  • Retiring: Implementors notified that the service is discontinued and not to be used for new developments
