Yeah, this is a pretty huge release for multithreaded PRNG usage. Courtesy of chethega (I should probably know his Discourse user name, but I don’t) initially and pushed over the finish line by @jeff.bezanson, with much assistance from @rfourquet. The down side is that the default RNG now produces a totally different stream of values from previous releases, but it seems worth the potential disruption to get such a huge increase in PRNG speed and concurrency.
