Warning! SpinDynamica 3.6.x with Mathematica v13

Erroneous results have been reported when using SpinDynamica v3.6.x with Mathematica version 13.

This is very surprising behaviour since Mathematica should be backwards compatible.

This has been pinned down to a surprising inconsistency in the handling of SparseArray objects between Mathematica versions 12 and 13.  A bug report has been submitted to wolfram.com.

SpinDynamica v3.7 includes a workaround for known symptoms,

All SpinDynamica users using Mathematica version 13 should upgrade to SpinDynamica v3.7 or later.
