Given this week's release of [1]Flatpak 1.17 for app sandboxing, open-source developer Sebastian Wick published a blog post on Tuesday around the latest Flatpak developments and a look ahead at some of the feature development planned. Arguably most significant of that is the plans for systemd-appd.

Sebastian Wick and Adrian Vovk are planning to develop "systemd-appd" as a new service to allow querying running app instances. The plans for systemd-appd are for being able to authenticate Flatpak instances and working towards a goal of supporting nested sandboxing. This will also be useful for work around PipeWire, eliminating the D-Bus proxy, and other modernization work.

Moving forward Flatpak and Flatpak-Next development is going to work on code in the areas of:

- Work on the systemd-appd concept

- Make varlink a feasible alternative to D-Bus

- D-Bus filtering in the D-Bus daemons

- Network sandboxing via pasta

- PipeWire policy for sandboxes

- New Portals

The systemd-appd at this point still needs to be developed but will be interesting to see how it turns out along with these other interesting Flatpak developments.
