This is the latest major update to the Inter font. From the designer’s tweet:

“After two years of work on a new version of Inter, I'm so proud that it's finally released. (It's been in beta for the past year)

The changes are vast. Most notably there are six additional "Display" designs for large delicious type”

Shame this hasn't got more coverage here on HN. A phenomenal effort.
