[template history[]
[h4 Boost-1.49]
* Deprecated wrongly named `twothirds` math constant in favour of `two_thirds` (with underscore separator).
(issue [@https://svn.boost.org/trac/boost/ticket/6199 #6199]).
* Refactored test data and some special function code to improve support for arbitary precision and/or expression-template-enabled types.
* Added new faster zeta function evaluation method.
Fixed issues:
* Corrected CDF complement for Laplace distribution (issue [@https://svn.boost.org/trac/boost/ticket/6151 #6151]).
* Corrected branch cuts on the complex inverse trig functions, to handle signed zeros (issue [@https://svn.boost.org/trac/boost/ticket/6171 #6171]).
* Fixed bug in `bessel_yn` which caused incorrect overflow errors to be raised for negative ['n] (issue [@https://svn.boost.org/trac/boost/ticket/6367 #6367]).
* Also fixed minor/cosmetic/configuration issues [@https://svn.boost.org/trac/boost/ticket/6120 #6120], [@https://svn.boost.org/trac/boost/ticket/6191 #6191],
[@https://svn.boost.org/trac/boost/ticket/5982 #5982], [@https://svn.boost.org/trac/boost/ticket/6130 #6130],

* Added an example of using Inverse Chi-Squared distribution for Bayesian statistics,
provided by Thomas Mang.

* Corrected wrong out-of-bound uniform distribution CDF complement values [@https://svn.boost.org/trac/boost/ticket/5733 #5733].
* Enabled long double support on OpenBSD (issue [@https://svn.boost.org/trac/boost/ticket/6014 #6014]).
* Changed nextafter and related functions to behave in the same way as other implementations - so that nextafter(+INF, 0)
is a finite value (issue [@https://svn.boost.org/trac/boost/ticket/5823 #5832]).
* Changed tuple include configuration to fix issue when using in conjunction with Boost.Tr1 (issue [@https://svn.boost.org/trac/boost/ticket/5934 #5934]).
* Changed class eps_tolerance to behave correctly when both ends of the range are zero (issue [@https://svn.boost.org/trac/boost/ticket/6001 #6001]).
* Fixed missing include guards on prime.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5927 #5927]).
* Removed unused/undocumented constants from constants.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5982 #5982]).
* Fixed missing std:: prefix in nonfinite_num_facets.hpp (issue [@https://svn.boost.org/trac/boost/ticket/5914 #5914]).
* Minor patches for Cray compiler compatibility.
[h4 Boost-1.47]
* Added changesign function to sign.hpp to facilitate addition of nonfinite facets.
* Addition of nonfinite facets from Johan Rade, with tests,
examples of use for C99 format infinity and NaN, and documentation.
* Added tests and documentation of changesign from Johan Rade.
[h4 Boost-1.46.1]
* Fixed issues [@https://svn.boost.org/trac/boost/ticket/5095 #5095], [@https://svn.boost.org/trac/boost/ticket/5095 #5113].
[h4 Boost-1.46.0]
* Added Wald, Inverse Gaussian and geometric distributions.
* Added information about configuration macros.
* Added support for mpreal as a real-numbered type.
[h4 Boost-1.45.0]
* Added warnings about potential ambiguity with std random library in distribution and function names.
* Added inverse gamma distribution and inverse chi_square and scaled inverse chi_square.
* Editorial revision of documentation, and added FAQ.
[h4 Boost-1.44.0]
* Fixed incorrect range and support for Rayleigh distribution.
* Fixed numerical error in the quantile of the Student's T distribution: the function was
returning garbage values for non-integer degrees of freedom between 2 and 3.
[h4 Boost-1.41.0]
* Significantly improved performance for the incomplete gamma function and its inverse.
[h4 Boost-1.40.0]
* Added support for MPFR as a bignum type.
* Added some full specializations of the policy classes to reduce compile times.
* Added logistic and hypergeometric distributions, from Gautam Sewani's Google Summer of Code project.
* Added Laplace distribution submitted by Thijs van den Berg.
* Updated performance test code to include new distributions, and improved the performance of the non-central distributions.
* Added SSE2 optimised __lanczos code, from Gautam Sewani's Google Summer of Code project.
* Fixed bug in cyl_bessel_i that used an incorrect approximation for [nu] = 0.5, also effects the non-central
Chi Square Distribution when [nu] = 3, see bug report [@https://svn.boost.org/trac/boost/ticket/2877 #2877].
* Fixed minor bugs [@https://svn.boost.org/trac/boost/ticket/2873 #2873].
[h4 Boost-1.38.0]
* Added Johan R'''å'''de's optimised floating point classification routines.
* Fixed code so that it compiles in GCC's -pedantic mode (bug report
[@https://svn.boost.org/trac/boost/ticket/1451 #1451]).
[h4 Boost-1.37.0]
* Improved accuracy and testing of the inverse hypergeometric functions.
[h4 Boost-1.36.0]
* Added Noncentral Chi Squared Distribution.

[h4 Boost-1.35.0: Post Review First Official Release]
* Added Policy based framework that allows fine grained control
over function behaviour.
* [*Breaking change:] Changed default behaviour for domain, pole and overflow errors
to throw an exception (based on review feedback), this
behaviour can be customised using __Policy's.
* [*Breaking change:] Changed exception thrown when an internal evaluation error
occurs to boost::math::evaluation_error.
* [*Breaking change:] Changed discrete quantiles to return an integer result:
this is anything up to 20 times faster than finding the true root, this
behaviour can be customised using __Policy's.
* Polynomial/rational function evaluation is now customisable and hopefully
faster than before.
* Added performance test program.
[h4 Milestone 4: Second Review Candidate (1st March 2007)]
* Moved Xiaogang Zhang's Bessel Functions code into the library,
and brought them into line with the rest of the code.
* Added C# "Distribution Explorer" demo application.
[h4 Milestone 3: First Review Candidate (31st Dec 2006)]
* Implemented the main probability distribution and density functions.
* Implemented digamma.
* Added more factorial functions.
* Implemented the Hermite, Legendre and Laguerre polynomials plus the
spherical harmonic functions from TR1.
* Moved Xiaogang Zhang's elliptic integral code into the library,
and brought them into line with the rest of the code.
* Moved Hubert Holin's existing Boost.Math special functions
into this library and brought them into line with the rest of the code.
[h4 Milestone 2: Released September 10th 2006]
* Implement preview release of the statistical distributions.
* Added statistical distributions tutorial.
* Implemented root finding algorithms.
* Implemented the inverses of the incomplete gamma and beta functions.
* Rewrite erf/erfc as rational approximations (valid to 128-bit precision).
* Integrated the statistical results generated from
the test data with Boost.Test: uses a database of expected
results, indexed by test, floating point type, platform, and compiler.
* Improved lgamma near 1 and 2 (rational approximations).
* Improved erf/erfc inverses (rational approximations).
* Implemented Rational function generation (the Remez method).
[h4 Milestone 1: Released March 31st 2006]
* Implement gamma/beta/erf functions along with their incomplete counterparts.
* Generate high quality test data, against which future improvements can be judged.
* Provide tools for the evaluation of infinite series, continued fractions, and
rational functions.
* Provide tools for testing against tabulated test data, and collecting statistics
on error rates.
* Provide sufficient docs for people to be able to find their way around the library.
