This is a major update. The following major new features were added:
- Virtual machines can be fully encrypted now, including the VM config logs and saved states
(CLI only for now)
- OCI: Cloud virtual machines can be added to Virtual Machine Manager and controlled as
local VMs
- OCI: Cloud networks can now be configured via Network Manager tool same way as it is
done for Host-only and NAT networks
- GUI: Added a new utility similar to "top" or "resource monitor" which lists peformance
statistics (CPU usage, RAM usage, disk I/O rate, etc.) of running guests
- GUI: Reworked the new vm wizard to integrate the unattended guest OS installation and
to have a more streamlined work flow
- GUI: Added a new help viewer widget which enables the user manual to be navigated and
searched

ing around the GUI
- GUI: Improved theme support on all platforms. Linux and macOS got native engine while
Windows host got it separately implemented.
- GUI: Large icon update.
- Audio recording: Now using Vorbis as the default audio format for WebM containers. Opus
is no longer being used.
- Audio: Added "default" host driver type to make it possible to move VMs (appliances)
between different platforms without the need of changing the audio driver explicitly. When
the "default" driver is selected, the best audio backend option for a platform will be used.
This is the default for newly created VMs.
- Guest Control: Implemented initial support for automatic updating of Guest Additions for
Linux guests

allow running VMS even when a usser is not being logged in (disabled by default, please
consult the manual)

works provided by Apple now.

with some of guest Desktop Environments

In addition, the following items were fixed and/or added:
- OCI: Cloud networking functionality is enhanced for local VMs, now local VMs could be
connected to cloud networking
- GUI: Improved behavior of the virtual machine list and various VM related tools in case
multiple items are selected
- GUI: On available platforms, added a new option to disable the host’s screensaver
- GUI: Reworked global preferences, machine settings and the wizards to improve stability
