thank you!

I've fixed these, regenerating them now. will push after

[danielk43]

Thank you for the quick fix!

Just looked at the commit - the one patch CVE-2021-47455 still was valid for the gs101 and gs201 builds and did not error out when applied.

NP if intentionally removed but wanted to make sure that detail wasn't missed in case my description wasn't clear.

[SkewedZeppelin]

Yes, I track those too, but I don't have a good way to handle them yet.
