Gluster users - Mar 2019 - what versions are packaged for what Linux distro?

Hello,

following the announcement of GlusterFS 6, I tried to install the
package from the Ubuntu PPA on a 16.04 "xenial" machine, only to find
out that GlusterFS 6 is only packaged for Ubuntu "bionic" and up.

Is there an online page with a table or matrix detailing what versions
are packaged for what Linux distribution?

Thanks,
Riccardo
