Introduction
So much of the understanding of the performance of mu2e depends on simulation studies that a change in geant version could have far-reaching effects. This page contains a checklist for tests to perform before moving to a new geant. Typically, some tests would be skipped because the expert decides the effort to validate would not be justified for the low level of risk.
v4_10_4
Started Mar 1, 2018, proposed update to v4_10_4 from v4_10_2_p03e.
How to trigger Mu2e specific electromagnetic option4 (_EMZ) with modified msc model transition energy (committed 3/16/18), off by default, on where noted.

How to change the stepper to the new one requiring fewer field evaluations:

clhep 2.4.0.0 (not used yet) will enable the switch from HepJamesRandom to MixMax random number engine (art sets the default)
