* `flyweight` now replicates the initializer-list constructors and assignment operators of its underlying type.
* Fixed intermodule static initialization problem (ticket [ticket 9553]).
* Maintenance fixes.
* [phrase library..[@/libs/math/index.html Math]:]
* 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.
* 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.
* 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].
* [phrase library..[@/libs/multi_index/index.html Multi-index Containers]:]
* The `erase(iterator)` member function of hashed indices used to have poor performance under low load
