+11 November 2020 - G.Cosmo
+- Synchronised with CLHEP-2.4.4.0:
+  * Vector (G.Amadio <amadio@cern.ch>)
+    o Removed obsolete #pragma interface/implementation
+      These pragmas are obsolete since GCC 2.7.2.
+      https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Interface.html.
+    o Get rid of switch statement in operator()/operator[] of Hep3Vector
+      Replaced dx/dy/dz with operator[] in Hep3Vector
+      Note: The substitution of x()/y()/z() in operator() is necessary to
+            avoid infinite recursion, as x()/y()/z() are now defined in terms
+            of operator[] instead.
+    o Replaced private dx/dy/dz with public x()/y()/z() in Hep3Vector
+      This is in preparation to change the data layout of Hep3Vector
+      by replacing the private dx/dy/dz members with a vector, data[3],
+      to allow us to remove the inefficient switch from operator[]().
+  * Vector, Random (V.Vassilev <v.g.vassilev@gmail.com>)
+    o Added missing includes for translation unit encapsulation.

+- Updated values in SystemOfUnits.h and PhysicalConstants.h for:
+  - e_SI, electron charge
+  - h_Planck, Planck constant
+  - Avogadro, Avogadro constant
+  - k_Boltzmann, Boltzmann constant
+  based on May 2019 redefinition of SI units. References:

+14 July 2020 - K.Savvidis, G.Cosmo
+- Use 32-bit internal seeds types coherently in MixMaxRng.
+  Addressing CLHEP JIRA ticket #156.

 19 November 2019 - G.Cosmo
 - Fixed warnings for cases of implicit type conversions in
   Rand*Ziggurat classes.
