23.11.0 'Saturn' released

· 5 min read

Saturn is the latest entry in our quarterly rollup series. It branches off from our main rolling Voyager development into a fixed target for our partners to qualify and build upon.

Saturn is the sixth planet from the Sun and is the second-largest planet in our solar system, after Jupiter. It is large enough that it can fit more than 760 Earths inside it.

Despite its enormous size, Saturn has a relatively fast rotation. A day on Saturn lasts only about 10.7 hours. This rapid rotation causes the planet to flatten slightly at the poles and bulge at the equator.

Saturn has been known since ancient times, and its rings were first observed by Galileo Galilei in 1610. The true nature of the rings was identified by Christiaan Huygens in 1655.

As for the software, Comet 23.11.0 Saturn brings 8 new features and 23 enhancements, including our new VMware Protected Item type.

As always for a new quarterly release, there are two changelogs for 23.11.0 Saturn depending on whether you are coming from the previous quarterly release or the previous Voyager release:

Changes compared to 23.8.3

New Features
