How to update Nuitrack version for Unity?

We are using Nuitrack Unity package.
How to update if there is a new version?

Thanks,

Also how do I know there is a new version released?
The version information is not clear on the download page.

The latest version of Unity Assets can be obtained directly from the Unity editor.
To update the package, you just need to download the new version and re-import it into the project (when importing, the files with changes will be indicated, as well as the new ones added).
To get the news about the release of new Nuitrack versions, you can subscribe to the newsletter on our website.
Also, the information on the version and release date is on GitHub.
