iTunes did another one of its seemingly random minor updates again the other day. And today I opened it to watch one of the few podcasts that I use still use it for only to notice that it looked a bit weird.

As it turns out Apple has finally (and this is a real finally) adopted HiDPI support on Windows. From their release notes,

Windows:
This update is designed for high DPI displays so text and images appear sharper and clearer. It also includes minor app and performance improvements.

I would guess that they got a little push in this direction since iTunes is supposed to be moving to the Windows Store, but it is 2017, and HiDPI has been a thing for over five years. There are complaints about it not scaling correctly above 250%, but this fixes one of the last major desktop apps. Not a minor thing when many laptops come with 4k screens now.
