This version includes a bounded simulated annealing algorithm, an interior point (Newton) solver for constrained optimization with nonlinear constraints, improved API for Fminbox, inplace keyword for optimize.
Additionally there are a few internal changes. We've simplified the complex number support, changed the line searches API, and a range of bug fixes.

This release introduces optimization over Riemannian manifolds and a trust region method that takes advantage of cheap Hessian-vector products.
This release also improves the documentation and some subtle changes to output that improves compatibility with numbers types other than standard floats. It introduces docstrings for many methods, such that you can now write ?BFGS to get information about the syntax to construct a BFGS instance.
