Flatpak (previously xdg-app) is a new system for desktop application bundling and deployment. It allows you to build an application once and then deploy on all Linux distributions, running in a sandboxed environment.
This talk will give a status update on where Flatpak is as a project, and how GNOME is using it. Then it will talk about future plans, focusing on what is needed going forward to make GNOME applications work well in a sandboxed environment.
