Most notably, this version removes the flaky microbenchmark-based FMA CPU instruction set detection and replaces it with an opt-in when you want java.lang.Math.fma() to be used in most matrix, vector and quaternion methods. You must make sure that your CPU supports this, though, as otherwise a ton of memory is allocated for BigDecimal instances when using double-precision matrices/vectors/quaternions.
