Only vaguely related, but: Why is everything called a.*64 these days? I keep getting confused between amd64, arm64 and aarch64...

This is often used in relation to the processor architecture. The 64 is added to indicate it's a 64 bit CPU architecture.

This is to distinguish it to the for a long time common 32 bit CPU architectures.

Looking at the current market you could think that there are mostly 64 bit CPUs sold nowadays, but many people still use (older) 32 bit CPUs.
