Progeny Genealogy (Software) has released an updated version of its Charting Companion program, Charting Companion 8.4, for Windows and Mac. Charting Companion is exactly what it sounds like a genealogy utility that helps with creating family trees/charts, using your existing genealogy software (the list of compatible genealogy software is extensive – see this page).
The only note about the version 8.4 update is that it supports Legacy Family Tree 10, which was recently released. The previous update released back in February, Charting Companion 8.3, added support for Family Tree Maker 2024.

On a side note, I checked the macOS version, and it shows the following:
Charting Companion 8.4.10 (x86_64) macOS 10.16
With that said, Legacy Family Tree is natively a Windows-only app (it can be run under virtualization software), so the Mac version having the same version number most likely is just meant to keep the two builds in sync.
