      Release Notes: This release adds xGEQRT, a QR factorization facility that enables better performance when the blocked reflectors need to be reused. It adds xGEQRT3, a recursive QR factorization facility that has high performance on tall and skinny matrices. It adds xTPQRT, a collection of Communication-Avoiding QR sequential kernels. It replaces the build system with CMAKE for better portability. It adds Doxygen documentation. It integrates LAPACKE's C language APIs into LAPACK.

                      Release Notes: Many new algorithms. Several implementations have been replaced with much faster and/or much more accurate versions. Support has been added for exploiting fast single- precision hardware where possible. Thread safety has been added. Reliability on SMP systems has been improved. There is additional support for matrices with NaN/subnormal elements, and optimization of the balancing routines. Several bugfixes, including a rare bug that could produce wildly inaccurate results with QR factorization.
