Purpose
When a subscribed repo ships a Release and polling sees it, macOS may show a banner, and the timeline / Activity can show unread marks. A notification is a reminder. Assets still download from the list.System banner plus Settings → General → Notifications Release switch

Checklist
Content usually includes repo name, tag, and Release title. A click jumps to that Release / timeline.
To quiet things: disable system banners, or the in-app Release switch, or unsubscribe low-priority repos to free slots.
