new distributions (Gumbel, Laplace, Logistic, Nakagami), and
improvements on percentiles algorithms (better handling for NaNs
in the regular algorithm, plus a new storeless implementation).
Bicubic splines interpolators have been fixed and new implementations
added. There have been numerous bug fixes and several improvements

The minimum version of the Java platform required to compile and use
Apache Commons Math is Java 5.

Changes in this version include:
New features:
o MATH-1066: Added Bessel functions of the first kind, based on NetLib implementation. Thanks to Brian Wignall.
o MATH-1180: Method to create a sequence of integers (in "o.a.c.m.util.MathArrays").
o MATH-1172: New class "SimpleCurveFitter": Boiler-plate code to allow fitting of
a user-defined parametric function.
o MATH-1173: New classes "TricubicInterpolatingFunction" and "TricubicInterpolator" to
replace "TricubicSplineInterpolatingFunction" and "TricubicSplineInterpolator".
o MATH-1166: New classes "BicubicInterpolatingFunction" and "BicubicInterpolator" to
replace "BicubicSplineInterpolatingFunction" and "BicubicSplineInterpolator".
o Boundary attributes in regions now provides the BSP tree nodes that

storing data in memory (i.e. as StorelessUnivariateStatistic). Thanks to Venkatesha Murthy.
Fixed Bugs:
o MATH-1142: Improve performance of kalman gain calculation in "KalmanFilter" by
directly solving a linear system rather than computing the matrix
inverse. Thanks to Arne Schwarz.
o MATH-1181: Fixed integer overflow in KolmogorovSmirnovTest causing 2-sample test
to use exact method when the product of the sample sizes exceeds
Integer.MAX_VALUE, resulting in effectively hung execution.
o MATH-1178: Fixed example in userguide ("stat" section). Thanks to Dmitriy.
o MATH-1175: Fixed inverse cumulative probability of 0 in "LaplaceDistribution". Thanks to Karsten Loesing.
o MATH-1174: Fixed a problem with too thin polygons considered to have infinite size.
