- v0.08
- v0.07
- v0.042
- v0.01

- Remotion of trailing whitespaces (Shlomi Fish) - Documentation fixes (Shlomi Fish) - Remotion of PkgConfig from runtime requirements (Bartosz Jakubski) - Indentation fixes (Bartosz Jakubski) - Installation feedback improvements (Bartosz Jakubski)

- Fixed bug on uncleared error variable (5.8.9) - Added OO transpose method for matrices (Ivan Baidakou)

- Make Math::GSL play nice with GSL 1.12 - Added swap() to Vector objects with tests and docs - Added p-norms to Vector objects via norm() and normalize() - Added operator overloading so that abs $vector == $vector->norm - Added as_vector() to Matrix and MatrixComplex objects - Added inverse(), is_square(), det(), lndet(), zero() and identity() to Matrix objects - Added inverse(), is_square(), det(), lndet(), zero(), identity() and hermitian() to MatrixComplex objects - Added dot product to Matrix objects - Fixed various typos in documentation - Fixed warnings about overloaded operators in Matrix and BLAS - Overloaded '==' and '!=' for MatrixComplex and Matrix objects - Fixed amd64 -fPIC compile failure - Added tests to Monte and refactor Sort tests - Refactored and improve error checking in callback interface - Fixed 'NaN' test failures (thanks CPANtesters!)

- Fixed RT#40947: configure_requires ExtUtils::PkgConfig bug - Added reverse() and swap() methods to VectorComplex objects with tests and docs - as_list() and get() now work on VectorComplex objects as_list() returns a list of Math::Complex objects get() returns a list of Math::GSL::Complex objects - Math::GSL::Test::ok_status() now takes an optional message argument - Added KNOWN_BUGS - Added Math::GSL::Test::is_status_ok() - New subsytems: VectorComplex and MatrixComplex - Operator overloading for addition and subtraction with vectors - Added example: examples/matrix/nonsymmetric_eigen Shows how to find the eigenvalues of a nonsymmetric matrix - Added copy() method to vectors - Improved Vector docs - Sped up vector dot products by 15x using BLAS function gsl_blas_ddot NOTE: using gsl_blas_ddot($x->raw,$y->raw) directly is still about 10 times faster than $x * $y due to error checking and function call overhead - Separated POD and Perl code out of SWIG interface files, yay for proper syntax highlighting - Added stub test files for Heapsort, IEEEUtils, Multimin, Siman, Wavelet2D - All test files now keep track of how many tests should run - Fix an include bug in Histogram2D which caused the build to fail (Thierry) - Operator overloading for addition, multiplication and subtraction on Matrix objects (Thierry)

- Chebyshev Series Approximation, with tests and docs - Examples and new documentation in Statistics, as well as tests (Thierry) - Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge - Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs - Documentation for Math::GSL::Test - Improved introduction examples in Math::GSL - Improved Minimization subsystem tests, but it is not functional - Added examples/fft/forward_real - Added example/deriv/basic This shows the simple fact that d/dx(sin(x)) = cos(x) - Added example/sf/erfc_check (thanks to Keith Lofstrom) Script which tests the erfc() special function against computing the integral definition with gsl_integration_qagiu() - Added example/vector/speed This shows a considerable performance boost using Math::GSL::Vectors instead of List::Util when searching for the min and max elements of large sets of random numbers. - Fixed return signature of gsl_deriv_* functions to return a flat list - Fixed some failing tests relating to -Duselongdouble (Sisyphus) - Fix location of shared objects (Sisyphus) - Added raw() method to RNG objects

- Darwin support! - Minimum Perl version changed to 5.8.0 - Make platform check compile time constants for performance aka The Wilhelm Speedup (thanks to Eric Wilhelm <scratchcomputing@gmail.com>) - FFT for real data - Numerical derivatives fully implemented - Integration subsystem, gsl_integrate_qags() and gsl_integrate_qagi(), etc.. - QNG : Non-adaptive Gaussian (uses fixed number of sample points in interval) - QAG(S) : Adaptive Gaussian (Singluar) (slices interval up based on properties of the function) - QAGI : Adaptive Gaussian with infinite integration range - other are supported but not tested - Initial Monte tests - Initial Multiroots tests - More nan/inf fixes on MSWin32 from <sisyphus@cpan.org> - Stripping of binaries on Windows, which significantly reduces size from <sisyphus@cpan.org> - Full support and tests for all functions in the Sort subsystem - Added 'examples/benchmark/sort' to show performance of gsl_sort() - Added 'examples/clicker/chart' to show graphing of functions - Added 'examples/gsl_repl' which is a rapid prototyping tool/interactive interpreter - Compile support for GSL's as old as 1.8 (test suite still needs to be properly guarded)

- Continued porting to MSWin32, fixing many NaN and Inf handling issues

- Large documentation improvements - MSWin32 support thanks to testing and feedback from <sisyphus@cpan.org>

- Initial CPAN release

- Started change to Test::Class

- Added swig interface files and swig-ified build script - initial tests for special function library gsl_sf <--> Math::GSL::Sf - Proof Of Concept: makegsl and testgsl
