I have upgraded to Heredis 2019 for Mac, purchased via App Store. It reports version 19.3.0, and no further updates appear in the App Store.
I am using the English version, and for the most part everything seems fine. However, certain dialog boxes appear in French rather than English.
In particular, if I start a new tree, in the Family/Immediate Family view, create the first person, add a child, and then add a spouse, after I've entered the spouse information, I get a popup that says:
"NOBODY Jane est-elle la mère de SMITH John ?"
rather than
"Is NOBODY Jane the mother of SMITH John?"
It's not a big deal - the French is easy enough to understand, but something that should get patched - or maybe at least change the choices for the dialog box to be Oui/Non to match instead of Yes/No
