A family of Microsoft word processing software products for creating web, email, and print documents.
So I made a little investigation and installed every version before 16.43.
I found that font smoothing was quietly removed in version 16.41, that appeared to be just a security update (!). And of course Microsoft Office team didn't share this in release notes.
Here's the difference (for fullscreen view):
16.40
16.41
Note, that the difference can be better seen on "low resolution" (1920x1080) screen. However, you may see the difference in this way:
16.40
16.41
Believe me, on Full HD monitor it's night and day. If you are not on Full HD monitor now, you may need direct comparison (like opening these images in different tabs or alongside each other) to see the difference.
Sadly, the date smooth text was removed forever wasn't commemorated 😊, as it was really an end of the era. Anyway, I found the right version (Office 2019 16.40), so I hope this will help someone.
P.S. It would be nice if Office team tell someone when they stop supporting thousands of displays/computers models. Thank you! 🙂
