@godotalgorithm, any apprehensions about the test changes?

This looks ok to me - you are now getting MOPAC from conda-forge (which I will be actively maintaining), some reference numbers have been changed, and the "electronic energy" was removed.

The "electronic energy" has been confusing people (it is NOT a total electronic energy for the molecule), so it has been removed from the default output (it is still accessible with a keyword) and I'd prefer not to emphasize it. The forces produced by MOPAC are derivatives of the "heat of formation", so that is the primary energetic quantity of relevance.

The reference numbers (they seem like geometric data for water?) have shifted a bit, but that isn't surprising of an optimized geometry as MOPAC's default geometric convergence isn't that tight and a lot of small changes have happened behind the scenes in the last few years to perturb these results.

Maybe also update the suggestion on how to install Mopac at

Great! I grouped mopac with the d3/d4 and geometry optimizers for testing, but if you ever find it would benefit from its own testing lane, that can be arranged.

Thanks for the confirmation that accumulated small shifts likely, esp. when combined with geometric algorithms.
