 1. New Sculpt OS version 21.03

 With our biannual releases of Sculpt OS, we make the most recent
 advances of Genode publicly available in the form of a general-
 purpose operating system that can be used on regular PC hardware.
 Just last week, we published Sculpt OS version 21.03:


 This version allows for the interactive assignment of real-time
 priorities to components, it comes with numerous performance and
 usability improvements, and bears the first fruits of our new
 architecture for pluggable device drivers. Thanks to the latter,
 the system becomes tolerant against classes of driver-related
 failures. For example, Sculpt OS can now even gracefully recover
 from a crashing graphics driver.

 An overview of these and further changes since the previous
 version is given the following article:


 2. Genode OS Framework 21.02 released

 The user-visible features of Genode 21.02 that we released at the
 end of February are the addition of VirtualBox 6, mobile-data
 connectivity via LTE, pluggable network drivers, and initial
 support for the Pine-A64-LTS board. It also revives the support
 for RISC-V.

 Some of these topics have been in the works since a long time.
 For example, VirtualBox 6 is not merely an update of our existing
 port of VirtualBox 5 but a fresh re-take condensing years of

 The LTE and Pine-A64 topics are primarily motivated by our goal
 to use Genode on the Pinephone by the end of the year, thereby
 attaining a device that is usable, affordable, and trustworthy.

 Other notable improvements range from added VirtIO-block device
 support for virtual machines on ARM, our revived developments
 for RISC-V, to VFS support for named pipes. You can find all the
 details presented in our comprehensive release documentation:


 3. FOSDEM recordings of our pluggable-device-drivers talk

 Among the variety of topics presented at this year's microkernel
 developer room at FOSDEM, we presented our recent work on
 pluggable device drivers. In the meantime, the recordings of
 the presentation have become available under the following link:


 As explained and demonstrated during the talk, this architectural
 change paves the ground for a variety of desirable features such
 as resilience against flaky device drivers, self-healing systems,
 and rigid power management.

 Thanks to the organizers of FOSDEM for pulling off the online
 version of our beloved gathering, and in particular to Martin
 Decky for organizing the virtual microkernel developer room along
 with the panel session that nicely wrapped up the event!
