This component library uses Semantic Versioning.
Every new release has a version number that has 3 parts: [major].[minor].[patch]
This is the meaning when one of those versions is upgraded:
The version information can be found in the changelog
You can click to an older version of the componentlibrary. It is also possible to use an older version in your application but it is recommended to upgrade to the latest version when possible.
When implementing a newer version you should always update the url of all the scripts and stylesheets mentioned in the How To Use docs. The url always contains the version number.
