  • v1.7.0 M3 is now at similar quality levels as v1.6.0 M2 while being ~50% faster
  • v1.7.0 M4 is now at similar quality levels as v1.6.0 M3 while being ~40% faster
  • v1.7.0 M5 is now at similar quality levels as v1.6.0 M4 while being ~30% faster
  • v1.7.0 M6 is now at similar quality levels as v1.6.0 M5 while being ~25% faster
