Flatpak 0.9.3 comes about 20 days after the release of Flatpak 0.9.2, and adds a great number of changes to flatpak-builder, among which we can mention the ability for the “flatpak-builder –run” command to grant D-Bus access to the app, and support for “bootstrap.sh” to be recognized as an autogen.sh alternative. To be able to pre-seed downloaded sources, Flatpak gained support for the “–extra-sources=” argument, along with support for “–bundle-sources” argument, which produces a runtime using the sources used for building the application. Moreover, Flatpak is now capable for handling trailing whitespace in Git submodule URIs.
