 ## `zstd`

-`obs-service-recompress` requires `zstd`.

+If `diary-nightly` for ArchLinux is built with `tar.gz` compression, the build will not be shown on the [download page](https://software.opensuse.org//download.html?project=home%3Ain0rdr&package=diary-nightly) because the download button for ArchLinux is missing, see also:

+* https://archlinux.org/news/now-using-zstandard-instead-of-xz-for-package-compression
+
+Therefore, build the ArchLinux package with the `.pkg.tar.zst` extension/compression:
+
+```
+# ./diary-nightly/PKGBUILD
+PKGEXT='.pkg.tar.zst'
+```
+
+If the ZST compression (new defacto standard since [2020-01-04](https://archlinux.org/news/now-using-zstandard-instead-of-xz-for-package-compression)) does not work, use the xz compression as an alternative as described in [openSUSE/software-o-o/#844](https://github.com/openSUSE/software-o-o/issues/844):
+
+```
+PKGEXT='.pkg.tar.xz'

 Patch `zstd.spec`, such that RHEL build require `glibc-static` and openSUSE builds require `glibc-devel-static`:
