The old random number generators have been removed from Cloudy. These were based on the Mersenne twister algorithm and the Box-Muller method for generating random numbers with a normal (Gaussian) distribution. The new code uses a fully vectorized version of [xoshiro256\*\*](http://xoroshiro.di.unimi.it/), while the random numbers with a normal distribution are now generated using the [Ziggurat](https://www.jstatsoft.org/article/view/v005i08) algorithm. Both methods are much faster than the old ones. An additional advantage is that the new code is fully aware of parallellization in the code, meaning that parallel ranks created with MPI or fork will automatically have a different sequence of random numbers. The code now generates a random seed at the start of execution by default (usually derived from /dev/urandom), unless the `-s` command line parameter described above is used.
