[h4 Math-2.5.1 (Boost-1.63)]

Patches:

* Fixed evaluation of zero polynomial in polynomial.hpp, see [@https://svn.boost.org/trac/boost/ticket/12532 12532].
* Fixed missing header include in boost/math/tools/tuple.hpp, see [@https://svn.boost.org/trac/boost/ticket/12537 12537].

[h4 Math-2.5.0 (Boost-1.62)]

New Features:

* Enabled all the special function code to work correctly with types whose precision can change at runtime: for example type `mpfr_float` from Boost.Multiprecision.

Patches:

* Fix tgamma_delta_ratio for cases where the delta is small compared to the base.
* Fix misc GCC-4.4 test failures.

[h4 Math-2.4.0 (Boost-1.61)]

New Features:

* Polynomial arithmetic added to tools.


[h4 Math-2.3.0 (Boost-1.60)]

New Features:

* Promote the root finding and function minimization code to first class citizens - these are now officially supported as part of the library.
* Allow the library to be used and tested with compiler exception handling support turned off.  To better facilitate this
the default error handling policies have been changed to ['errno_on_error] but only when the compiler has no exception handling support.

Patches:

* Fix behaviour of the non-central chi-squared distribution when the non-centrality parameter is zero to match the chi-squared,
see [@https://svn.boost.org/trac/boost/ticket/11557 11557].
* Fix comments in code for the hypergeometric to match what it actually does, also fixes the parameter access functions to return
the correct values.  See [@https://svn.boost.org/trac/boost/ticket/11556 11556].
* Stopped using hidden visiblity library build with the Oracle compiler as it leads to unresolved externals from the C++ standard library.
See [@https://svn.boost.org/trac/boost/ticket/11547 11547].
* Fix unintended use of __declspec when building with Oracle C++.  See [@https://svn.boost.org/trac/boost/ticket/11546 11546].
* Fix corner case bug in root bracketing code, see [@https://svn.boost.org/trac/boost/ticket/11532 11532].
* Add some missing typecasts in arguments to std::max in Bernoulli code.  See [@https://svn.boost.org/trac/boost/ticket/11453 11453].
* Fix mistaken assumptions about the possible values for FLT_EVAL_METHOD.  See [@https://svn.boost.org/trac/boost/ticket/11429 11429].
* Completely revamped performance testing and error-rate measuring code so we can more easily document how well (or not!) we're doing.
This information will hopefully get more frequently updated in future as it's more or less automatically generated - see the /reporting/
sub-directory for more information.
* Fix some corner cases in the beta, incomplete beta, and incomplete beta derivative.  With thanks to Rocco Romeo.
* Reorganized the Bessel functions internally to improve the performance of Jn and Yn.
* Fixed skewness formula for triangular distribution, see [@https://svn.boost.org/trac/boost/ticket/11768 #11768].
* Fixed some examples so they compile on Unix platforms which have an ::exception struct declared, see [@https://svn.boost.org/trac/boost/ticket/11827 #11827].
* Correct mistake in triangular distribution skewness formula [@https://svn.boost.org/trac/boost/ticket/11768 11768],
reported by Juan Leni.

[h4 Math-2.2.1]

Patch release for Boost-1.58:

* Minor [@https://github.com/boostorg/math/pull/13#issuecomment-98905579 patch for Haiku support.]
* Fix the decimal digit count for 128-bit floating point types.
* Fix a few documentation typos.

[h4 Math-2.2.0 (boost-1.58.0)]

* Added two new special functions - __trigamma and __polygamma.
* Fixed namespace scope constants so they are constexpr on conforming compilers, see https://svn.boost.org/trac/boost/ticket/10901.
* Fixed various cases of spurious under/overflow in the incomplete beta and gamma functions, plus the elliptic integrals,
with thanks to Rocco Romeo.
* Fix 3-arg __legendre_p and __legendre_q functions to not call the policy based overload if the final argument
is not actually a policy.
* Cleaned up some dead code in the incomplete beta function, see [@https://svn.boost.org/trac/boost/ticket/10985 #10985].
* Fixed extreme-value pdf for large valued inputs, see [@https://svn.boost.org/trac/boost/ticket/10938 #10938].
* Large update to the Elliptic integral code to use Carlson's latest algorithms - these should be more stable, more accurate
and slightly faster than before.  Also added support for Carlson's RG integral.
* Added __ellint_d, __jacobi_zeta and __heuman_lambda elliptic integrals.
* Switched documentation to use SVG rather than PNG graphs and equations - browsers seem to have finally caught up!

[h4 Math-2.1.0 (boost-1.57.0)]

* Added __hyperexponential_distrib.
* Fix some spurious overflows in the incomplete gamma functions (with thanks to Rocco Romeo).
* Fix bug in derivative of incomplete beta when a = b = 0.5 - this also effects several non-central distributions,
see [@https://svn.boost.org/trac/boost/ticket/10480 10480].
* Fixed some corner cases in __round.
* Don't support 80-bit floats in cstdfloat.hpp if standard library support is broken.

[h4 Math-2.0.0 (Boost-1.56.0)]

* [*Breaking change]: moved a number of non-core headers that are predominantly used for internal
maintenance into `libs/math/include_private`.  The headers effected are `boost/math/tools/test_data.hpp`,
`boost/math/tools/remez.hpp`, `boost/math/constants/generate.hpp`, `boost/math/tools/solve.hpp`,
`boost/math/tools/test.hpp`.
You can continue to use these headers by adding `libs/math/include_private` to your compiler's include path.
* [*Breaking change]: A number of distributions and special functions were returning the maximum finite value
rather than raising an __overflow_error, this has now been fixed, which means these functions now behave as
documented.  However, since the default behavior on raising an __overflow_error is to throw a `std::overflow_error`
exception, applications which have come to reply rely on these functions not throwing may experience exceptions
where they did not before.  The special functions involved are __gamma_p_inva, __gamma_q_inva,
__ibeta_inva, __ibetac_inva, __ibeta_invb, __ibetac_invb, __gamma_p_inv, __gamma_q_inv.  The distributions
involved are __pareto_distrib, __beta_distrib, __geometric_distrib, __negative_binomial_distrib,
__binomial_distrib, __chi_squared_distrib, __gamma_distrib, __inverse_chi_squared_distrib,
__inverse_gamma_distrib.  See [@https://svn.boost.org/trac/boost/ticket/10111 #10111].
* Fix __round and __trunc functions so they can be used with integer arguments, see [@https://svn.boost.org/trac/boost/ticket/10066 #10066].
* Fix Halley iteration to handle zero derivative (with non-zero second derivative), see [@https://svn.boost.org/trac/boost/ticket/10046 #10046].

[h4 Math-1.9.1]

* Fix Geometric distribution use of Policies, see [@https://svn.boost.org/trac/boost/ticket/9833 #9833].
* Fix corner cases in the negative binomial distribution, see [@https://svn.boost.org/trac/boost/ticket/9834 #9834].
* Fix compilation failures on Mac OS.

[h4 Math-1.9.0]

* Changed version number to new Boost.Math specific version now that we're in the modular Boost world.
* Added __bernoulli_numbers, changed arbitrary precision __tgamma/__lgamma to use Sterling's approximation (from Nikhar Agrawal).
* Added first derivatives of the Bessel functions: __cyl_bessel_j_prime, __cyl_neumann_prime, __cyl_bessel_i_prime, __cyl_bessel_k_prime, __sph_bessel_prime and __sph_neumann_prime (from Anton Bikineev).
* Fixed buggy Student's t example code, along with docs for testing sample means for equivalence.
* Documented `max_iter` parameter in root finding code better, see [@https://svn.boost.org/trac/boost/ticket/9225 #9225].
* Add option to explicitly enable/disable use of __float128 in constants code, see [@https://svn.boost.org/trac/boost/ticket/9240 #9240].
* Cleaned up handling of negative values in Bessel I0 and I1 code (removed dead code), see [@https://svn.boost.org/trac/boost/ticket/9512 #9512].
* Fixed handling of very small values passed to __tgamma and __lgamma so they don't generate spurious overflows (thanks to Rocco Romeo).
* [@https://svn.boost.org/trac/boost/ticket/9672 #9672 PDF and CDF of a Laplace distribution throwing domain_error]
Random variate can now be infinite.
* Fixed several corner cases in __rising_factorial, __falling_factorial and __tgamma_delta_ratio with thanks to Rocco Romeo.
* Fixed several corner cases in __rising_factorial, __falling_factorial and __tgamma_delta_ratio (thanks to Rocco Romeo).
* Removed constant `pow23_four_minus_pi ` whose value did not match the name (and was unused by Boost.Math), see
[@https://svn.boost.org/trac/boost/ticket/9712 #9712].

[h4 Boost-1.55]

* Suppress numerous warnings (mostly from GCC-4.8 and MSVC) [@https://svn.boost.org/trac/boost/ticket/8384 #8384], [@https://svn.boost.org/trac/boost/ticket/8855 #8855],
[@https://svn.boost.org/trac/boost/ticket/9107 #9107], [@https://svn.boost.org/trac/boost/ticket/9109 #9109]..
* Fixed PGI compilation issue [@https://svn.boost.org/trac/boost/ticket/8333 #8333].
* Fixed PGI constant value initialization issue that caused erf to generate incorrect results [@https://svn.boost.org/trac/boost/ticket/8621 #8621].
* Prevent macro expansion of some C99 macros that are also C++ functions [@https://svn.boost.org/trac/boost/ticket/8732 #8732] and [@https://svn.boost.org/trac/boost/ticket/8733 #8733]..
* Fixed Student's T distribution to behave correctly with huge degrees of freedom (larger than the largest representable integer) [@https://svn.boost.org/trac/boost/ticket/8837 #8837].
* Make some core functions usable with `long double` even when the platform has no standard library `long double` support [@https://svn.boost.org/trac/boost/ticket/8940 #8940].
* Fix error handling of distributions to catch invalid scale and location parameters when the random variable is infinite [@https://svn.boost.org/trac/boost/ticket/9042 #9042] and [@https://svn.boost.org/trac/boost/ticket/9126 #9126].
* Add workaround for broken <tuple> in Intel C++ 14 [@https://svn.boost.org/trac/boost/ticket/9087 #9087].
* Improve consistency of argument reduction in the elliptic integrals [@https://svn.boost.org/trac/boost/ticket/9104 #9104].
* Fix bug in inverse incomplete beta that results in cancellation errors when the beta function is really an arcsine or Student's T distribution.
* Fix issue in Bessel I and K function continued fractions that causes spurious over/underflow.
* Add improvement to non-central chi squared distribution quantile due to Thomas Luu,
[@http://discovery.ucl.ac.uk/1482128/ Fast and accurate parallel computation of quantile functions for random number generation, Doctorial Thesis 2016].
[@http://discovery.ucl.ac.uk/1463470/ Efficient and Accurate Parallel Inversion of the Gamma Distribution, Thomas Luu]
[h4 Boost-1.54]

* Major reorganization to incorporate other Boost.Math like Integer Utilities Integer Utilities (Greatest Common Divisor and Least Common Multiple), quaternions and octonions.
Making new chapter headings.

* Adjusted heuristics used in Halley iteration to cope with inverting the incomplete beta in tricky regions
where the derivative is flatlining.  Example is computing the quantile of the Fisher F distribution for probabilities
smaller than machine epsilon.  See ticket [@https://svn.boost.org/trac/boost/ticket/8314 #8314].

[h4 Boost-1.53]

* Fixed issues [@https://svn.boost.org/trac/boost/ticket/7325 #7325], [@https://svn.boost.org/trac/boost/ticket/7415 #7415]
and [@https://svn.boost.org/trac/boost/ticket/7416 #7416], [@https://svn.boost.org/trac/boost/ticket/7183 #7183],
[@https://svn.boost.org/trac/boost/ticket/7649 #7649], [@https://svn.boost.org/trac/boost/ticket/7694 #7694],
[@https://svn.boost.org/trac/boost/ticket/4445 #4445], [@https://svn.boost.org/trac/boost/ticket/7492 #7492],

* Improve accuracy of Bessel J and Y for integer orders thanks to suggestions from Rocco Romeo.

[h4 Boost-1.52]

* Corrected moments for small degrees of freedom [@https://svn.boost.org/trac/boost/ticket/7177 #7177] (reported by Thomas Mang).
* Added [link math_toolkit.airy Airy functions] and [link math_toolkit.jacobi Jacobi Elliptic functions].
* Corrected failure to detect bad parameters in many distributions
[@https://svn.boost.org/trac/boost/ticket/6934 #6934] (reported by Florian Schoppmann)
by adding a function check_out_of_range to test many possible bad parameters.
This test revealed several distributions where the checks for bad parameters were ineffective,
and these have been rectified.
* Fixed issue in Hankel functions that causes incorrect values to be returned for ['x < 0] and [nu] odd, see [@https://svn.boost.org/trac/boost/ticket/7135 #7135].
* Fixed issues [@https://svn.boost.org/trac/boost/ticket/6517 #6517], [@https://svn.boost.org/trac/boost/ticket/6362 #6362],
[@https://svn.boost.org/trac/boost/ticket/7053 #7053], [@https://svn.boost.org/trac/boost/ticket/2693 #2693],
[@https://svn.boost.org/trac/boost/ticket/6937 #6937], [@https://svn.boost.org/trac/boost/ticket/7099 #7099].


* Permitted infinite degrees of freedom [@https://svn.boost.org/trac/boost/ticket/7259 #7259]
implemented using the normal distribution (requested by Thomas Mang).
* Much enhanced accuracy for large degrees of freedom [nu] and/or large non-centrality [delta]
by switching to use the Students t distribution
(or Normal distribution for infinite degrees of freedom)
 centered at delta,
when [delta] / (4 * [nu])  < epsilon for the floating-point type in use.
[@https://svn.boost.org/trac/boost/ticket/7259 #7259].
It was found that the incomplete beta was suffering from serious cancellation errors
when degrees of freedom was very large. (That has now been fixed in our code,
but any code based on Didonato and Morris's original papers
(probably every implementation out there actually) will have the same issue).

[h4 Boost-1.51]
See Boost-1.52 - some items were added but not listed in time for the release.

[h4 Boost-1.50]

* Promoted math constants to be 1st class citizens,
including convenient access to the most widely used
built-in float, double, long double via three namespaces.
* Added the Owen's T function and Skew Normal distribution written by Benjamin Sobotta: see __owens_t and skew_normal_distrib.
* Added Hankel functions __cyl_hankel_1, __cyl_hankel_2, __sph_hankel_1 and __sph_hankel_2.
* Corrected issue [@https://svn.boost.org/trac/boost/ticket/6627 #6627 nonfinite_num_put formatting of 0.0 is incorrect]
based on a patch submitted by K R Walker.
* Changed constant initialization mechanism so that it is thread safe even for user-defined types, also
so that user defined types get the full precision of the constant, even when `long double` does not.
So for example 128-bit rational approximations will work with UDT's and do the right thing, even though
`long double` may be only 64 or 80 bits.

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

* Added tests to use improved version of lexical_cast which handles C99 nonfinites without using globale facets.

* 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]).

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]).
