@maxphunin The Cloudron App Store already has had that version out for a while, over 18 days ago. https://forum.cloudron.io/topic/6936/umami-package-updates/19?_=1669953895802

I think the issue if you're not seeing it is that you have to manually check for updates if you've disabled automatic updates.
