CI: duplicated source archives in releases?

[ivan-mogilko]

There's something that is bugging me in our github releases: they include repository source in four different archive formats:

• source.tar.bz2
• source.tar.gz
• source.tar.xz
• source.zip

What was the reason to have all of them? I may guess that "zip" format is maybe meant for Windows users, but do not contemporary Linux systems also support reading zip archives by default, and even if they do not, why have 3 different variants of "tar"?

I wondered the same, it must be the CI adding the extras somehow becasue github should only have the two default ones at the very bottom (which can't be excluded)
