Alpha
This implementation guidance is the Alpha release to support the development of NEWS2.
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, and 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.
A pre-release version MAY be denoted by appending a hyphen. Refer to Semantic Versioning - Item 9 see here
Pre-release Labels
These labels will be taken from the GDS development process stages, and will be one of:
Experimental: Early development/POC version of a product for early sight during discovery
Alpha: Initial test product, likely to change substantially, or be discontinued as the project develops
Beta: APIs that are still under active development and subject to change, but that are likely to progress into a live product
Release Candidate: Products that are largely complete, unlikely to change substantially, but still need further testing before becoming live
Live: Release live Products
Discontinued: APIs which have been discontinued and should not be used for new development.
