I'm not sure to understand what's the issue.

file zstd-1.3.8.tar.gz
zstd-1.3.8.tar.gz: gzip compressed data, from FAT filesystem (MS-DOS, OS/2, NT), original size 1862954             
file zstd-1.3.8.tar
zstd-1.3.8.tar: POSIX tar archive

I don't see any double-gzipping here.

These archives were produced by the same script which produced v1.3.7 a few months ago.

I'm seeing the same issue as @fenrus75. On OpenBSD:

$ ftp https://github.com/facebook/zstd/releases/download/v1.3.8/zstd-1.3.8.tar.gz

Ok, we're not sure what went wrong. But I was able to reproduce the issue.

We've replaced the zstd-1.3.8.tar.gz asset in the release. And I have tried round-tripping it and what I get back from GitHub now hash-matches zstd-1.3.8.tar.gz.sha256 and unpacks correctly.
