The process.release property returns an Object containing metadata related to the current release, including URLs for the source tarball and headers-only tarball.

process.release contains the following properties:

sourceUrl:string

an absolute URL pointing to a .tar.gz file containing the source code of the current release.

a string label identifying the LTS label for this release. This property only exists for LTS releases and is undefined for all other release types, including Current releases. Valid values include the LTS Release code names (including those that are no longer supported).

'Fermium':
