Zorin OS 15.3 comes six months after the release of Zorin OS 15.2 to offer those who want to deploy the Ubuntu-based operating system on new computers an up-to-date installation media, based on the latest Ubuntu 18.04.5 LTS (Bionic Beaver) release. This means that Zorin OS 15.3 is powered by a new kernel, namely Linux 5.4 LTS, from the Ubuntu 20.04 LTS (Focal Fossa) operating system series, which is also shipping with the Ubuntu 18.04.5 LTS release by default. Of course, Zorin OS 15.3 also inherits all of Ubuntu 18.04.5 LTS’s updated components, such as the latest LibreOffice 6.4.6 office suite, Mozilla Firefox 80.0.1 web browser, and many others.
