Thank you for the prompt response.

> I don't see see the fix to ecc_ecdsa_verify backported in this mr (https://git.lysator.liu.se/nettle/nettle/-/commit/2397757b3f95fcae1e2d3011bf99ca5b5438378f), that seems quite important?

We only import any missing functionalities in the minimum supported version of nettle, which in this case are only Ed448 and GOSTDSA:
