With CentOS 6 reaching EOL in November 2020, we just dropped support for it. 2.46.0 was the last release to support it and the about-to-be-released 2.46.1 will not support building on CentOS 6.
We have an interesting situation coming up this year where CentOS 8 will go EOL before CentOS 7. That is not a typo. The future is something called CentOS Stream, which is upstream from RHEL. So they are changing from Fedora → RHEL → CentOS to Fedora → CentOS → RHEL. Given CentOS Stream actually concurrently exists alongside CentOS 8, maybe it is upstream from CentOS 8 (Fedora → Centos Stream 8 → RHEL 8 → CentOS 8) but I honestly have no idea. Clear as mud?
So we have a decision to make: what do we do when CentOS 8 goes EOL in December 2021? Regardless of what we decide, it seems we will have a degraded ability to support RHEL.
We still have a long runway to decide, but I thought I may as well raise the issue now.
