Dear List,

After staying with a frozen MKIV version for time-critical work for a while, I took the plunge and ran one of my longer math-heavy documents through LMTX. To my delight, it mostly looks fine or trivially fixable.
There is one problem I have with enumerations. The spacing between them in LMTX is notoriously smaller than in MKIV. 

I bet there is a parameter I can set to tweak that? Below is a MWE with output for both engines. 
Thanks!

Matthias
