| This file is used by the maven-changes-plugin to generate the release notes. |
| Useful ways of finding items to add to this file are: |
| |
| 1. Add items when you fix a bug or add a feature (this makes the |
| release process easy :-). |
| |
| 2. Do a bugzilla search for tickets closed since the previous release. |
| |
| 3. Use the report generated by the maven-changelog-plugin to see all |
| CVS commits. Set the project.properties' maven.changelog.range |
| property to the number of days since the last release. |
| |
| |
| The <action> type attribute can be add,update,fix,remove. |

| <release version="1.1-RC1" date="TBD" |
| description="This is a maintenance release containing bug fixes and enhancements. |
| All API changes are binary compatible with version 1.0. The enhancements |
| include some new probability distributions, a Fraction class, new matrix |
| and numerical utilities, and a PRNG pluggability framework making it |
| possible to replace the JDK-supplied random number generator in |
| commons-math (and elsewhere) with alternative PRNG implementations."> |
| <action dev="psteitz" type="fix" issue="35434" due-to="Jörg Weimar"> |
| Changed Fraction(double) to correctly handle near-integral arguments. |
| </action> |
| <action dev="psteitz" type="fix" issue="35431" due-to="Jörg Weimar"> |
| Changed lcm to throw ArithmeticException (instead of returning bogus |
| value) if the result is too large to store as an integer. |
| </action> |
| <action dev="psteitz" type="fix" issue="32663" due-to="Mary Ellen Foster"> |
| Added factories for TTest, ChiSquareTest and TestUtils class with |
| static methods to create instances and execute tests. |
| </action> |
| <action dev="psteitz" type="update" issue="35042" due-to="Paul Field"> |
| Eliminated repeated endpoint function evalutations in BrentSolver, SecantSolver. |
| </action> |
| <action dev="psteitz" type="update" issue="35007" due-to="Rodrigo di Lorenzo Lopes"> |
| Added setSubMatrix methods to RealMatrixImpl, BigMatrixImpl. To |
| Preserve backward compatibility with version 1.0, these methods were |
| not added to the RealMatrix, BigMatrix interfaces. |
| </action> |
| <action dev="psteitz" type="update"> |
| Added createXIdentityMatrix methods to MatrixUtils and deprecated |
| getIdentity methods in RealMatrixImpl, BigMatrixImpl. |
| Modified RealMatrixImpl, BigMatrixImpl constructors to throw |
| IllegalArgumentExceptions instead of ArrayIndexOutOfBounds when |
| dimension arguments are not positive. |
| </action> |
| <action dev="psteitz" type="update"> |
| Made PRNG pluggable for classes in the random package. Added |
| RandomGenerator interface extracted from java.util.random and abstract |
| implementation, AbstractRandomGenerator providing default |
| implementations of methods based on nextDouble(). Added a constructor |
| taking a RandomGenerator as an argument to RandomDataImpl. Changed |
| ValueServer to use a RandomData in its constructor. Changes to |
| 1.0 classes should be backward compatible (including serialization). |
| </action> |
| <action dev="psteitz" type="update" due-to="C. Scott Ananian"> |
| Ported numerics improvements in commons lang Fraction implementation. |
| Added utility methods for overflow-checked integer arithmetic and |
| improved gcd method in MathUtils. |
| </action> |
| <action dev="psteitz" type="fix" issue="34677" due-to="Gilles Gaillard"> |
| Fixed error in TTestImpl.homoscedasticTtest. Implementation was |
| incorrectly using heteroscedastic t statistic. Also improved |
| sensitivity of test cases. |
| </action> |
| <action dev="psteitz" type="fix" issue="34448" due-to="Gilles Gaillard"> |
| Fixed javadoc errors. One-sided t-test significance adjustment was |
| reversed in javadoc for boolean-valued test methods. |
| </action> |
| <action dev="brentworden" type="fix" due-to="Ben Litchfield"> |
| Fixed bug in PolynomialSplineFunction to allow evaluation of the |
| function at the last knot point. |
| </action> |
| <action dev="brentworden" type="add"> |
| Added Weibull distribution implementation. |
| </action> |
| <action dev="brentworden" type="add"> |
| Added Cauchy distribution implementation. |
| </action> |
| <action dev="brentworden" type="add"> |
| Added convenience methods for rounding. |
| </action> |
| <action dev="brentworden" type="add" due-to="C. Scott Ananian"> |
| Added Fraction class based on commons-lang implementation. With the |
| fraction class, FractionFormat and ProperFractionFormat classes were |
| added to provide fraction formatting and parsing. |
| </action> |
| </release> |

| description="Jakarta Commons Math 1.0 - General Availability Release"> |
| <action dev="psteitz" type="fix" due-to="Hans van der Heijden" |
| issue="32531"> |
| Fixed error in ChiSquareTestImpl. Tables containing zeros were |
| (incorrectly) causing IllegalArgumentExceptions to be thrown. |
| </action> |
| <action dev="psteitz" type="fix" issue="32538"> |
| Removed JDK 1.4-dependent code from CertifiedDataAbstractTest, |
| InvalidMatrixException and MatrixIndexException. Also dropped |
| BeanTransformer, BeanTransformerTest from the release. |
