Flatpak 1.17.1 and 1.17.2 were released today, building on the earlier Flatpak 1.17 development series. A notable new feature in these updates is the addition of support for building OCI bundles with Zstd compressed layers. This enhancement follows Flatpak 1.17's previous introduction of the ability to sideload applications directly from OCI images. The integration of Zstd compression aims to optimize the storage and distribution of Flatpak applications by potentially reducing bundle sizes and improving transfer efficiency, further aligning Flatpak with broader Open Container Initiative standards. Flatpak 1.17.2 also included fixes for release artifacts following 1.17.1.
