+[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.

+
+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]).

+
+* 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]).

+
+[h4 Boost-1.46.1]

+[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)]

+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.
