About: Armadillo is a template C++ linear algebra library aiming towards a good balance between speed and ease of use. Matrix decompositions are provided through optional integration with LAPACK, or one of its high performance drop-in replacements (eg. Intel MKL, OpenBLAS).

• added automatic SSE2 vectorisation of elementary expressions (eg. matrix addition) when using GCC 4.7+ with -O3 optimisation
• added detection of the OpenBLAS library during installation, which provides multi-threaded (parallelised) matrix multiplication
• added support for saving & loading of cubes in HDF5 format
• much faster median()
• faster handling of compound expressions with transposes of complex vectors or submatrix rows
• faster as_scalar() for compound expressions
• minor fix for linking with MKL on Ubuntu systems
