Is this project still maintained?

I am using regularly fontello (and previously icomoon) for some small and/or personal projects. I find it really useful, especially if you have a limited subsets of icons and want to avoid the unnecessary load of a full font.

However, I see that the FontAwesome version used on the website is still v4, despite it is almost 10 years old now (now we are at v7), and the latest commit is 4 years old. I often find myself finding a icon that would fit well in my project in FontAwesome and realizing that it is not present on fontello.

I don't think the app needs more features (it is already good as it is), but is it planned to update the font files used on the app? (I see pull requests that were not merged).
If the project is abandoned, does someone know if development continues on a fork somewhere else?
