+- Armadillo no longer depends on boost libraries, and requires
+  arpack-ng instead; adapt build and run-time requirements
+  appropriately
+- Fix baselibs.conf for so name version update
+- Add libatlas3 dependencies as recommended by upstream.

+Mon Jan  6 21:27:36 UTC 2014 - badshah400@gmail.com

+- Update to Version 4.000.0 (Feral Steamroller)
+  + added eigen decompositions of sparse matrices: eigs_sym() and
+    eigs_gen()
+  + added eigen decomposition for pair of matrices: eig_pair()
+  + added simpler forms of eig_gen()
+  + added condition number of matrices: cond()
+  + expanded find() to handle cubes
+  + expanded subcube views to access elements specified in a vector
+  + template argument for running_stat_vec expanded to accept
+    vector types
+  + more robust fast inverse of 4x4 matrices
+  + faster divide-and-conquer decompositions are now used by
+    default for eig_sym(), pinv(), princomp(), rank(), svd(),
+    svd_econ()
+  + the form inv(sympd(X)) no longer assumes that X is positive
+    definite; use inv_sympd() instead
+  + added MEX connector for interfacing Octave/Matlab with
+    Armadillo matrices (contributed by George Yammine)
+- Packaging changes:
+  + SO version update to 4
+  + Remove appropriate win64 examples instead of win32
