Re: [brownie-announce] New version

[Brian O'Meara]

I've released an updated version of Brownie. The previous release had
a bug with discrete characters (thanks to Sam Price for pointing this
out) in that the program would crash when asked to compute
likelihoods (the error was due to my expecting a function from an
included library to return 1 when true but which included 0 when
true). The new version is also much faster at both continuous and
discrete trait optimization (uses an O(N) rather than O(N^2) Nelder-
Mead simplex optimizer, courtesy of the GNU Scientific Library).

Best,
Brian
