+- Update to version 2.4.0:
+  + Added shorter forms of transposes: .t() and .st()
+  + Added optional use of 64 bit indices, allowing matrices to
+    have more than 4 billion elements
+  + Added experimental support for C++11 initialiser lists
+  + Faster pinv()
+  + Faster inplace transpose
+  + Faster handling of expressions with diagonal views
+  + Fixes for handling expressions with aliasing and submatrices
+  + Fixes for linking on Ubuntu and Debian systems
+  + Fixes for inconsistencies in interactions between matrices
+    and cubes
+  + Refactored code to eliminate warnings when using the Clang
+    C++ compiler
+  + .print_trans() and .raw_print_trans() are deprecated.
+- Spec file cleanups:
+  + Use upstream provided tarballs (in tar.gz format) instead of
+    recompressing to tar.bz2
+  + Modify License tag in confomity with spdx.org specifications
