This is the best summary I could come up with:
Simon McVittie issued the Flatpak 1.15.7 pre-release on Wednesday with a few notable changes for this widely-used open-source app sandboxing and distribution framework.
Flatpak continues evolving nicely for this leading app sandbox and distribution solution widely used across many different Linux distributions that paired with Flathub make for very easy app access.
Introduced in Flatpak 1.15.7 is now the ability to automatically remove obsolete driver versions and other auto-pruned refs.
This will help eliminate excess baggage that builds up over time by automatically removing end-of-life runtimes that are no longer used.
Flatpak 1.15.7 also adds the "--socket=inherit-wayland-socket" argument to inherit the existing Wayland socket environment and automatically reloads the D-Bus session bus configuration when installing or upgrading apps to ensure any exported D-Bus services are recognized.
Flatpak 1.15.7 also does away with its existing Autotools build system support in favor of Meson.
