Package: unp Version: 2.0~pre9 I have tried to `unp` a .tar.zst file and it 'failed to detect file type'. It seems there is no support for .zst files on any version. Because people are increasingly turning to zstd for fast decompression and high compression ratios (e.g. support for initramfs compression with zstd came in Linux 5.9), I think it would be really useful to support zstd, especially considering that it (seems) to have different syntax and thus is more difficult to get accustomed to.
