+ Apache Commons Math Version 1.2-RC1
+ RELEASE NOTES
+
+
+This release combines bug fixes and new features. Most notable among the new
+features are the estimation, optimization, geometry and ode packages added
+from the Mantissa library. Implementations of fast Fourier transform, QR
+decomposition and several numerical integration algorithms have also been
+added, along with enhancements and extensions to packages included in Commons
+Math 1.1. This release is source and binary compatible with earlier versions
+of Commons Math.
+
+For more information on Apache Commons Math, see
+http://commons.apache.org/math/
+
+
+ SUMMARY OF CHANGES
+
+ADDITIONS
+
+* Added the estimation, optimization, geometry and ode packages from the
+ Mantissa library.
+
+* MATH-120. Added Pascal distribution implementation. Thanks to Todd C.
+ Parnell.
+
+* MATH-148. Added QR Decomposition. Thanks to Joni Salonen.
+
+* MATH-140. Added Fast Fourier Transform implementation. Thanks to Xiaogang
+ Zhang.
+
+* MATH-173. Added one-way ANOVA implementation. Thanks to Bob MacCallum.
+
+* Added an angle normalization method in MathUtils to force angles in some
+ user-defined interval
+
+* Added vectorial covariance computation (either sample or population
+ covariance)
+
+* Added multivariate summary statistics.
+
+
+BUG FIXES
+
+* Fixed numerous warnings in test code.
+
+* MATH-156. Use the initial guess provided by the user in
+ BrentSolver.solve(), thus improving speed. Thanks to Tyler Ward.
+
+* MATH-18. Made ComplexFormat format double values with a provided
+ NumberFormat instance instead of using the real part format for all values.
+ Thanks to Phil Steitz.
+
+* MATH-60. Modified ProperFractionFormat to reject embedded minus signs.
+ Thanks to Nhung Nnguyen.
+
+* MATH-151. Added a nextAfter method in MathUtils to return the next
+ machine-representable number in a specified direction from a given floating
+ point number. Used this to ensure that MathUtils.round does not return
+ incorrect results for numbers with bad IEEE754 representations. Thanks to
+ Luc Maisonobe.
+
+* MATH-85. Modified getSumSquaredErrors method in SimpleRegression to always
+ return a non-negative result. Thanks to Mark Osborn, Luc Maisonobe.
+
+* MATH-153. Corrected nextInt and nextLong to handle wide value ranges.
+ Thanks to Remi Arntzen.
+
+* MATH-166. Increased default precision of Gamma and Beta functions. Thanks
+ to Lukas Theussl.
+
+* MATH-167. Modified NormalDistributionImpl.cumulativeProbablity to catch
+ MaxIterationsExceededException and return 0 or 1, resp. if the argument is
+ more than 20 standard deviations from the mean.
+
+* MATH-174. Changed Mean.evaluate() to use a two-pass algorithm, improving
+ accuracy by exploiting the the fact that this method has access to the full
+ array of data values.
+
+* MATH-175. Added check and rescaling of expected counts to sum to sum of
+ expected counts if necessary in ChiSquare test. Thanks to Carl Anderson.
+
+* MATH-164. Handle multiplication of Complex numbers with infinite parts
+ specially.
+
+* MATH-182. Add integer overflow checks in Fraction constructor using double
+ parameter.
+
+* MATH-185. Throw EOFException when using empty files with ValueServer in
+ replay and digest modes.
+
+* MATH-184. Fixed AbstractIntegerDistribution cumulativeProbablility(-,-) to
+ correctly handle double arguments. Thanks to Yegor Bryukhov.
+
+
+UPDATES
+
+* MATH-158. Added log function to MathUtils. Thanks to Hasan Diwan.
+
+* MATH-160. Added two sample (binned comparison) ChiSquare test. Thanks to
+ Matthias Hummel.
+
+* MATH-170. Added SynchronizedDescriptiveStatistics class. Thanks to David J.
+ M. Karlsen.
+
+* MATH-154. Added addAndCheck, mulAndCheck, and subAndCheck MathUtils methods
+ for long integer arguments. Thanks to Remi Arntzen.
+
+* MATH-171. Merged most functions from ComplexUtils into Complex class, added
+ static factory method to Complex. Thanks to Niall Pemberton.
+
+* Deprecated abstract factory methods and made DescriptiveStatistics and and
+ SummaryStatistics concrete classes. Pushed implementations up from
+ DescriptiveStatisticsImpl, SummaryStatisticsImpl. Made implementations of
+ statistics configurable via setters.
+
+* MATH-176. Add errors guessing to least-squares estimators. Thanks to
+ Kazuhiro Koshino.
+
+* MATH-179. Add tests for Fraction constructor using double parameter. Thanks
+ to Niall Pemberton.
+
+* MATH-181. Add Fraction constructor using max denominator value. Thanks to
+ Niall Pemberton.
+
+* Added a equals and hash methods in MathUtils to check for double arrays
+
+* MATH-191. Added getSumOfLogs method to SummaryStatistics and made SumOfLogs
+ instance used by GeometricMean configurable.
+
+* MATH-188. Made numerator and denominator final in Fraction and deprecated
+ protected real and imaginary parts fields in Complex, making Fraction
+ immutable and preparing Complex to become fully immutable in 2.0. Thanks to
+ Sebastian Bazley.
+
+DEPRECATIONS SUMMARY
+
+* The abstract factory pattern used to enable pluggable implementations in the
+ statistics, analysis and distributions packages has been deprecated and
+ replaced by setter injection.
+
+* Non-localized exception messages and associated constructors have been
+ deprecated and replaced by localized versions.
+
+* Most methods from the ComplexUtils class have been deprecated, with
+ implementations moved to the Complex class.
+
+See "clirr-report.html" included in the binary distribution for a detailed list
+of API changes. The "errors" reported at the top of the report are due to
+protected fields being moved to superclasses. These fields are still available,
+so there is no backward compatibility issue.
