We do have some auto-generated update events that get put in the feed, but we're considering phasing those out. We really want developers to post an update when they are ready to announce. Additionally, a lot of the times developers will upload new builds that don't need an announcement. We feel like encouraging developers to post updates will keep the feed clean and more useful.
Viewing post in new uploads/updates in feed
sometimes even if they post an update there may be no feed notification, for example:
https://indivi.itch.io/elfjail/devlog/70826/elf-jail-r21
where neither the actual file update nor the dev's update post triggered there being something about it in my feed
