I see that these branches are merged now @ChrisRackauckas.

You also mentioned in this link, [Sub plus (₊) instead of dot in the dot notation in equations displayed by ModelingToolkit - #4 by zdenek\_hurak](https://discourse.julialang.org/t/sub-plus-instead-of-dot-in-the-dot-notation-in-equations-displayed-by-modelingtoolkit/61113/4), that these changed were going to be released ASAP. Are these changes already out?

Is there a way in Julia to get notifications of releases/changes in particular packages?
