Requiring ostree 2017.6 and bubblewrap 0.1.8 components, Flatpak 0.9.4 offers better progress reporting in both the command-line and user interface, improves the output of various commands, including list, info, remotes, and remote-ls, and implements a “flatpak repo” command to view information about local repositories. The “flatpak build” command was updated to kill all the processes in the sandbox when it exits, the “flatpak update –subpath=…” was also improved to update the app event when there’s no new upstream version and the subpath is different from the one installed, and exports are now whitelisted.
