Flatpak 1.10 development kicks off with the first unstable release, allowing us to have an early look at the new features and improvements. The biggest change in the upcoming series being the implementation of a new format for the summary file used when accessing an OSTree repository on the network. This major change in Flatpak 1.10 not only bumps the OSTree dependency to version 2020.8, but it also makes several underlying enhancements to the behavior of this universal binary format used by numerous application developers and GNU/Linux distribution maintainers to distribute third-party apps.
