Enceladus 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.

Enceladus is a moon of Saturn and is named after the giant Enceladus of Greek mythology. There are a few worlds that are thought to have liquid water oceans beneath their frozen shell, but Enceladus sprays its ocean out into space where spacecraft can sample it. From these samples, scientists have determined that Enceladus has most of the chemical ingredients needed for life, and likely has hydrothermal vents releasing hot, mineral-rich water into its ocean. Enceladus is about as wide as Arizona, and it also has the most reflective surface in our solar system. Because it reflects so much sunlight, the surface temperature is extremely cold, about minus 330 degrees Fahrenheit (minus 201 degrees Celsius).

As for the software, Comet 24.5.0 Enceladus brings 6 new features and 38 enhancements, including Changed Block Tracking support for Hyper-V and adding Impossible Cloud as a Storage Template provider.
