# Description
Try to add `aarch64-unknown-linux-musl` and
`armv7-unknown-linux-musleabihf` release target
I will test these two new targets in the nightly workflow, It should
work:
https://github.com/nushell/nightly/actions/runs/10692449465/job/29640875827,
and check the release binaries. If everything goes well we can add the
`musl` targets in the next release
