Earlier I noticed that the "New cartridges" tab adds the updates of the cartridges too.
But when I updated PICO-EXPLORER to 4.0, I haven't found it in that tab.

P.S. Changed the category of this post to "PICO-8: Chat" because almost nobody checks the general posts

I don't believe it has ever updated to show cart updates first. They just stay in the same relative position compared to other carts.
