- Move Vector, etc. into `.math` package - Drop many methods that will be auto-promoted anyways, eg. with `divide(int)` and `divide(double)` the first is now gone. - Take Block vectors into their own class hierarchy - Make it clear throughout the API what takes blockvectors - many more improvements
