              Apache Commons RNG 1.1 RELEASE NOTES

The Apache Commons RNG team is pleased to announce the commons-rng-parent-1.1 release!

The Apache Commons RNG project provides pure-Java implementation of pseudo-random generators.

Changes in this version include:

New features:
o RNG-37:  Implementation of the "Ziggurat" algorithm for Gaussian sampling.
o RNG-47:  "DiscreteProbabilityCollectionSampler": Sampling from a collection of items
        with user-defined probabilities (feature ported from "Commons Math").
o RNG-43:  "LogNormalSampler" with user-defined underlying "NormalizedGaussianSampler".
o RNG-39:  "UnitSphereSampler": generate random vectors isotropically located
        on the surface of a sphere (feature ported from "Commons Math").
o RNG-36:  "MarsagliaNormalizedGaussianSampler": Faster variation of the
        Box-Muller algorithm.
        This version is used within "AhrensDieterMarsagliaTsangGammaSampler"
        "MarsagliaLogNormalSampler" and "PoissonSampler" (generated sequences
        will thus differ from those generated by version 1.0 of the library).
o RNG-35:  New generic "GaussianSampler" based on "NormalizedGaussianSampler"
        marker interface.
        Implementation of "BoxMullerNormalizedGaussianSampler" deprecates
        "BoxMullerGaussianSampler".


Changes:
o RNG-42:  Use "ZigguratNormalizedGaussianSampler" within the library.
o RNG-46:  Following RNG-43, "BoxMullerLogNormalSampler" has been deprecated.
        Furthermore, its base class has been removed; although it is a binary
        incompatibility, it cannot cause any problem that were not already
        present in code using v1.0 of the library: Calls to the base class
        would have raised a NPE.
