Release Notes: Major enhancements are: support for std::complex and automatic differentation with FADBAD++, support for storing Vector in STL containers, sparse Jacobians in Gauss-Newton optimizer, pkg-config support, and const correctness. Minor enhancements include NaN-proofing of ConjugateGradient, more complete regression tests, correctness tests for SO3, and doxygen tag file support. In addition, a number of bugs have been fixed.
Release Notes: In addition to many bugfixes, several features have been added. Mixed static/dynamic slices. Built-in singular value decomposition (much faster than LAPACK for small to moderate sized matrices). Symmetric matrix square root and inverse square root. Accurate numerical derivatives (first and second) using Ridder's method. Efficient resizable vectors. A regression testing framework. Better backwards compatibility with TooN-1. Single precision LAPACK based Cholesky decomposition. More documentation.
