 * Add more sizes of icons including SVG, and add Keywords to the .desktop file
 * Documentation updates
 * Fix PeriodicExtension function
+* ErrorFunction (erf) is using MPFR for real values so it is far more precise
+  and faster
+* The fourier series example is no longer using a hand coded graph and hand
+  computed series, so it can now be easily modified to show series for
+  different functions
+* Fix GCC 5 compilation
 * A couple of minor fixes in the plotting code including one possible crasher
 * Translation updates (FIXME)
