- Update to v1.2
  * Changes in this version include:
    + New features:
      ~ NUMBERS-206: "Selection": Add selection of the k-th ordered
        element from an array.
      ~ NUMBERS-205: "Addition/Multiplication": Introduces isZero
        to Addition and isOne to Multiplication interfaces.
        Override the default implementation in implementing classes
        to avoid expensive equals(Object) operations. Thanks to
        Harald Kirsch.
      ~ NUMBERS-203: "DDField": Add a field for the DD number.
      ~ NUMBERS-193: "DD": Add an extended precision floating-point
        number. A double-double (DD) number is an unevaluated sum
        of two IEEE double precision numbers capable of
        representing at least 106 bits of significand.
      ~ NUMBERS-192: "Sum": Add subtract(Sum) method.
      ~ NUMBERS-191: "Stirling": Compute Stirling numbers of the
        first kind.
      ~ NUMBERS-29: Add "Stirling" class to compute Stirling
        numbers of the second kind.
    + Fixed Bugs:
      ~ NUMBERS-204: "Sum": Correct sub-normal round-off
        computation in sum of products.
      ~ NUMBERS-201: "FP64": Make equals consistent with hashCode.
      ~ NUMBERS-200: "Sum": Avoid a NaN result when combining Sum
        instances with infinite sums of the same sign. Thanks to
        Anirudh Joshi.
    + Changes:
      ~ "ArithmeticUtils": Improve performance of GCD for longs.
        Thanks to Matthias Langer.
      ~ "ArithmeticUtils": Improve performance of remainderUnsigned
        and divideUnsigned. Thanks to Sebb, Alex Herbert.
      ~ NUMBERS-199: "Precision": Document inaccurate decimal value
        representation when converting to and from a double in the
        round method.
- Reproducible builds: use SOURCE_DATE_EPOCH for timestamp

- Update to v1.1
  * Changes in this version include:
    + New features:
      ~ NUMBERS-70: Add a user guide.
      ~ NUMBERS-190: Add a Bill of Materials (BOM) to aid in
        dependency management when referencing multiple Apache
        Commons Numbers artifacts. The BOM should be used to ensure
        all imported artifacts are compatible.
      ~ NUMBERS-181: Updated support for the beta functions.
        "RegularizedBeta": Added the complement and derivative of
        the regularized beta function. Added "IncompleteBeta" and
        "Beta" classes. Functionality is ported from the Boost C++
        library.
      ~ NUMBERS-180: "GammaRatio": Compute the ratio of two gamma
        functions.
      ~ NUMBERS-177: "Erfcx": Compute a scaled complementary error
        function: erfcx(z) = erfc(z) * exp(z*z).
      ~ NUMBERS-175: "GeneralizedContinuedFraction": A continued
        fraction class to compute using a generator. Allows
        evaluation of continued fractions from a regular series
        where coefficients can be computed iteratively from the
        previous coefficients.
    + Fixed Bugs:
      ~ NUMBERS-185: "Precision": Allow Precision.compareTo using a
        maxUlps to be used for sorting. This corrects handling of
        NaN comparisons.
      ~ NUMBERS-182: "LogBeta": Avoid overflow for tiny arguments.
      ~ "BrentSolver": Avoid overflow creating the initial value
        between the lower and upper.
      ~ NUMBERS-173: "ContinuedFraction": Set a minimum bound on
        the relative error epsilon. Prevents an infinite loop when
        the epsilon is zero.
      ~ "FactorialDouble": Prevent caching values that are
        infinite. The cache will support factorials up to 170.
      ~ NUMBERS-170: "RegularizedBeta": Detect edge cases for
        arguments that can be evaluated by exploiting properties of
        the regularized beta function.
      ~ NUMBERS-168: "BrentSolver": Identify brackets with small
        objective values.
      ~ Fix wrong javadoc. Thanks to Arturo Bernal.
    + Changes:
      ~ NUMBERS-184: "Precision": Reduce number of operations in
        Precision.equals using a maxUlps.
      ~ NUMBERS-183: Improve the binomial coefficient classes.
        Avoid recursive method calls. Avoid overflow for
        BinomialCoefficientDouble for large results close to
        infinity. Use precomputed factorials and the LogBeta
        function for efficiency.
      ~ NUMBERS-178: "Factorial/FactorialDouble": Tabulate all
        factorials with exact 64-bit double representations of n!
        up to n=170. This change deprecates the FactorialDouble
        class and removes obsolete caching functionality.
      ~ NUMBERS-176: "ContinuedFraction": Update to use a shared
        implementation with GeneralizedContinuedFraction.
      ~ NUMBERS-174: "Gamma/LogGamma/RegularizedGamma": Update the
        gamma function implementations to increase accuracy and
        support for extreme values. Functionality is ported from
        the Boost C++ library.
      ~ NUMBERS-172: "Erf/Erfc": Use a rational function
        approximation accurate to 53-bits of precision. This
        replaces the use of the regularized gamma functions P and Q
        and increases accuracy at extreme limits of the function.
        Execution speed is improved. Functionality is ported from
        the Boost C++ library.
      ~ NUMBERS-171: "InverseErfc": Support full range of [0, 2].
        This lowers the supported minimum value from 2^-53 to
        double min value. Execution speed is improved.
        Functionality is ported from the Boost C++ library.
