Flatpak 0.9.1 Introduces New, Ninja-Based Build System, Flatpak-Builder Changes

Flatpak 0.9.1 appears to the be the first point release to the major Flatpak 0.9 series, and we say major because this milestone adds numerous improvements compared to the 0.8 branch, especially to the build system. The biggest change appearing to be a new Ninja-based build system called “cmake-ninja”. New features of the Flatpak 0.9.1 release include implementation of build-extension and build-runtime properties to flatpak-builder so you can build runtimes and extensions a lot easier than before, along with support for the “–from-git=URL” argument, which fetches the JSON manifest and other related files straight from a Git repository.
