Earlier this week, WordPress announced 4.6 “Pepper”. One of the interesting things in this release was the transition to native fonts for the dashboard:
The WordPress dashboard now takes advantage of the fonts you already have, making it load faster and letting you feel more at home on whatever device you use.
WordPress is 25% of the Internet, so a lot of site owners are going to get used to this. Last month GitHub switched as well.
It’s too early to tell if it’s a fad or the beginning of a longterm trend.
