This page lists features that are planned or under active development for Cloudmin, and their expected release versions :
Backups made by Cloudmin are not currently encrypted or signed, which makes storing them on untrusted remotely systems questionable. This feature will add GPG encryption and verification of backups, to prevent tampering or unauthorized access.
Hosting Virtualmin services for multiple systems
Virtualmin features like DNS and MySQL are currently run independently on each system, which consumes significant CPU and RAM. This feature will allow those features to be centrally hosted, which allows Virtualmin to be run on systems with much less RAM. This has been implemented, and is currently being beta tested by interested customers.
