Binaries
Svart's release scheme follows the microarchitecture levels.
x86_64-v3 is the fastest and recommended on modern systems.
x86_64-v2 is less fast but is compatible with CPUs pre-Haswell/Excavator.
x86_64-v1 is the slowest but compatible with almost anything.
See the readme for instructions on how to compile these versions yourself.
