GitHub Enterprise Cloud customers that use Enterprise Managed Users (EMUs) can now participate in a public beta for a new user role that has restricted visibility of internal repositories. The
guest collaborator role is defined via SCIM and assigned to users by the identity provider. Guest collaborators helps companies who work with contractors and other short-term partners in a flexible and managed fashion on specific projects, while also sharing code and ideas without restrictions amongst full enterprise members. When a guest collaborator is added to an organization they will only receive access to
internal visibility repositories within that organization.
