Sculpt OS release 22.04 | 2022-04-28
####################################
| Sculpt OS version 22.04 introduces the concept of service-level sandboxing
| and features completely new drivers for wireless, graphics, and USB.
On the user-visible surface, the new version of Sculpt OS looks and feels
familiar to users of the previous version. Under the hood, however, at the
nitty-gritty hardware-support level, it features completely revamped device
drivers for Intel wireless, Intel graphics, and USB.
In a major surgery, the new drivers got transplanted from the Linux kernel
version 5.14.21 using Genode's unique
[https://genode.org/documentation/release-notes/21.08#Linux-device-driver_environment_re-imagined - DDE]
approach.
In contrast to Linux where the drivers are part of the almighty operating-system
kernel, Sculpt OS hosts each of the drivers in a dedicated sandbox as plain
user-level component. So Sculpt users can enjoy the broad hardware support
of up-to-date Linux drivers without ultimately trusting those staggeringly
complex driver stacks.
Closely related, the support of hardware-accelerated graphics that we
introduced with the previous version
[https://genode.org/news/sculpt-os-release-21.10 - 21.10]
received substantial optimization and stabilization. With the new version,
Sculpt users can not only run native OpenGL applications but can even go as far
as using hardware-accelerated graphics via guest operating systems hosted
within VirtualBox on top of Sculpt.
Being a component-based operating system following the principle of least
privilege, Sculpt OS gives users ultimate control over the system resources
exposed to each component. The new version equips the user with additional
means to exercise control over the deployed software: A new optional
component called black hole can now be used as placeholder for various system
resources when deploying an application. For example, a virtual machine can
be shielded from the network by connecting its network traffic to the black
hole. This also works for audio, video capturing, USB, and other commonly used
system resources. As this mechanism works at the level of individual services,
the documentation refers to it as _service-level sandboxing_, resembling a
poster-child for the natural power of capability-based security.
Sculpt OS 22.04 is available as ready-to-use system image at the

with updated [https://genode.org/documentation/articles/sculpt-22-04 - documentation].
