Has there been a minor change in client design today?

Several overlay windows appear very different today, among those the confirmation popup when accepting and refusing trades and the one to list all games able to receive booster packs. Looks more phone-optimised, so I could imagine, it is intentional. Can anyone confirm this change, or should I have a look, if there's something wrong with my files?
P.S.: Not using Beta or any other changes from the regular client.

I don't know if anything was changed in the client, since I don't use the trading functionality of Steam, however, the Steam Community web interface has had some minor facelifting today, namely, modal windows (for reporting users and posts, warnings and bans) are now using the new chat design.

There was indeed a UI update.
Seems like all popup windows now have the same kind of shiny-bold style.

Thank you both.

I'll add this thread here as the update has seemingly botched the screenshot showcase https://steamcommunity.com/discussions/forum/0/1782766638535778521/

everything is bold, and there is even a new warning message in trade offers.

still won't stop people to get scammed, tho. because they won't read it.
