The feature-u project adheres to Semantic Versioning.
Each release is documented on the Revision History page (in addition to the Github Release Notes), and contains migration instructions.
feature-u maintains version-specific documentation for all of it's releases ... ex: https://feature-u.js.org/0.1.0/.
This allows you to match the correct documentation to the specific version you are using.
For your convenience the base https://feature-u.js.org/ will always reference the most current release.
