  We present WebProt\'eg\'e, a tool to develop ontologies represented in the
Web Ontology Language (OWL). WebProt\'eg\'e is a cloud-based application that
allows users to collaboratively edit OWL ontologies, and it is available for
use at https://webprotege.stanford.edu. WebProt\'ege\'e currently hosts more
than 68,000 OWL ontology projects and has over 50,000 user accounts. In this
paper, we detail the main new features of the latest version of WebProt\'eg\'e.
