Thanks for reporting @kentbull. I'll add it to the release targets and will let you know once it's available.

Alright, I published v1.3.5 which also provides the precompiled NIF for aarch64-unknown-linux-musl targets.
@kentbull, can you please give it another try and check if everything works as expected now?

@paulgoetze I can confirm this worked. Thank you! We will gladly use the hex.pm Alpine images now.
