Hi Nico, Toaster is waiting for the Layer Index to be populated for this very new release. Typically it takes a while for all the layers to catch up. As you observed, you can use “master” in the meantime since the divergence is minimal at this time. As per the event parsing error, I just sent a different email asking for the reproducer details.

I cloned the kirkstone repo, fired up toaster and tried to create a project with "Yocto Project 3.5 Kirkstone" as release (wondering about the 3.5, but its what it says :)), however, there is the usual info that no machines are available in the project configuration (Toaster has no machine information for this project. Sadly, machine information cannot be obtained from builds, so this page will remain empty.). Only choosing the "Yocto Project master" allows to choose a machine / add BSPs. Trying to build an image results in the usual error. Any idea on how to fix that? Thank you very much for your help!
