#. Red 3.5 comes with breaking changes for cog developers. Look at `Backward incompatible changes in Red 3.5 document <incompatible-changes-3.5>` and `Developer changelog <important-350-2>` for full details.
#. Fedora 35 and Debian 10 (Buster) are no longer supported as they have already reached their end of life.
#. On x86-64 systems, we now require that the CPU supports x86-64-v2 instruction set. This roughly translates to us dropping support for x86-64 CPUs that have been released before 2009.

On x86-64 systems, we now require that your CPU supports x86-64-v2 instruction set.
This roughly translates to us dropping support for x86-64 CPUs that have been released before 2009.
This has been mostly dictated by one of our dependencies but some Linux distributions
are already dropping support for it in their latest versions as well.
