No Linux binary.
What is a linux binary ?
There are so many (incompatible) distros.
So a unified linux binary would need static linking.
But if you are on Fedora or CentOS/RedHat 7 you can always use my copr (see signature).
Debian packages are not updated, and I think I will stop building for Debian, because I do not use it myself since years.
