It seems the blogpost under ITL’s blog caused some confusion.
As I understand it, the Qubes team is distinct from the one working on Wildland over at the Golem Foundation. Joanna’s blog just happen’s to be ITL’s blog (literally).
Also see the following quote:
On behalf of the whole Qubes team, I’d like to thank Joanna for all of her years of work on the project. Under her leadership, Qubes OS has accomplished a lot, with only some of its many successes mentioned above. We look forward to continuing to benefit from her expertise as an advisor. At the same time, we wish her all the best in her new role on the Golem Project!
Also, Wildland looks conceptually quite nice – as does pretty much everything else on ITL’s blog. Looking forward to testing it. Congrats
