Choosing a version
The latest tag is selected by the publisher and is not a guarantee of compatibility. Prerelease and deprecated status remain visible. Check your Node.js range and peer requirements on the exact version page, then review the maintainer’s release notes before upgrading.
Removed or unpublished versions may be absent. Historical download charts cover all package versions and do not show adoption of an individual release.
