22.11.0 ‘Ananke’ released

· 5 min read

Ananke 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.

Like Comet's previous recent quarterly software releases, "Ananke" is named after a moon of Jupiter, discovered as recently as 1951. It's the largest moon of the "Ananke group", a set of seven of the moons of Jupiter that have similar orbits and are thought to have a common origin. The moon is named after the ancient Greek mythological goddess of inevitability and necessity.

Ananke brings 12 features and 20 enhancements, including a new design for the Comet Backup desktop app; streaming restores for MySQL and Microsoft SQL Server; new integrations with and Gradient MSP; the ability to move users between tenants, and more.

As always for a new quarterly release, there are two changelogs for 22.11.0 "Ananke" depending on whether you are coming from the previous quarterly release or the previous Voyager release.

Changes compared to 22.8.0

  • The Authenticode certificate used by Comet has been renewed. When installing the Windows version of Comet Server or Comet Backup, you may see Windows Defender Smartscreen prompts for approximately one week as the replacement certificate builds reputation.
