@pshipton - Regarding

xLinux is compiled on CentOS 7, modifying the minimum glibc level to 2.17 from 2.12.

Isn't CentOS 7 no longer supported? We removed it from the list of supported platforms in the 0.46.0 release.

[pshipton]

Yes it's a bit weird, it's not in the supported list but we compile on it so the JVM can run there since RHEL 7 is still in extended support and possibly people are still using it.

So, I will give a note saying the same, that "Since RHEL 7 is in extended support, xLinux is compiled on CentOS 7, modifying the minimum glibc level to 2.17 from 2.12."?

No, we don't need to explain it, just state the change.
