Comment:

I am not sure which one is correct, but I noticed an inconsistencies between mamba and this repo. This repo supports x86_64_v3 as possible microarchitecture, but the __archspec value reported by mamba is instead x86_64-v3 (the difference is last underscore that is a dash), see:

• https://github.com/mamba-org/mamba/blob/83fdeae46572a05a1657395cccccbab74e8710d3/libmamba/src/core/virtual_packages.cpp#L177-L191

• microarch-level-feedstock/recipe/conda_build_config.yaml

  Line 15 in 1b446db

  - x86_64_v3

As a consequence of this, the packages in this feedstock can't be installed via mamba/micromamba.
