Atom feed not updated?

It seems the atom feed isn't being updated with the latest relases. For example, the latest Linux Appimage version is [123.0.6312.105-1](https://ungoogled-software.github.io/ungoogled-chromium-binaries/releases/appimage/64bit/123.0.6312.105-1) but the feed still lists 121.0.6167.160-1 as latest.
