The new version applies strict sandboxing +to each component individually. In particular, the host file system is +shielded from Genode components and Genode's least-privilege access-control +scheme comes into effect. + +As the second prominent architectural topic, the release features new +device-driver infrastructure for the ARM universe along with a unified +version of the formerly distinct virtual machine monitors for ARMv7 and +ARMv8. These are important steps to bring Genode on ARM to parity with the +x86 version. + +Further highlights of the release are the first feature-complete version +of our custom block-encryption component, the improved management of CPU +affinities on x86, and new tracing utilities. Last but not least, the +release is accompanied with an updated version of the Genode Foundations +book, reflecting the changes of the framework since one year ago. + +Read the details of the new release in the +[https:/documentation/release-notes/20.05 - release documentation of version 20.05...] + + Sculpt OS release 20.02 | 2020-03-10 ####################################
