Inter 4

[MonsterDeveloper]

Description

Recently a new major version 4.0 of Inter typeface was released.

I believe fontsource should update the font-files accordingly to use the latest version.

This has been suggested multiple times in the past and we've denied it as we mirror Google Fonts 1:1 programmatically and want to reduce the maintenance burden on our end.

However, I think there is enough demand from users to justify hosting a separate branch for Inter 4 until Google catches up. I suggest a new package Inter 4 which will be the manually maintained version for the font, whilst the original Inter package will continue to mirror Google Fonts. That being said, it'll be up to the community to maintain future updates if that is the case.

The downside is that our custom packager doesn't support variable fonts nor does it subset fonts so the end user will be getting 100kb WOFF2 files per weight. It would help a lot if fontsource/fontsource#39, fontsource/fontsource#728 and fontsource/fontsource#730 were to be resolved but they are huge undertakings.

Also worth tracking google/fonts#3429 which has discussion from the Google team to handle it soon.
