v0.16.1 Telesto

We are proud to announce the latest version update of Unikraft, v0.16.1!

This release contains both important and breaking changes related to the KConfig and syntax when statically specifying network interface information as well as the list of fstab (automount) entries at the kernel command-line.

Caution

We strongly advise upgrading to this latest version of Unikraft in order to continue to be compatible with future versions. In our accompanying blog post we include necessary migration steps. Additionally, we have released a new version of KraftKit (v0.7.2) which already incorporates an understanding these changes and have upgraded all images in the Unikraft Community Catalog of pre-built unikernel images.
