The main change in Flatpak 1.6.2 is a fix for a major regression affecting the download speeds during the installation of Flatpak apps from Fluthub. Therefore, the devs recommend everyone to update to this version for a better and faster Flatpak app installation experience. Also added in this release is the ability to correctly handle TMPDIR env var overrides when bwrap is setuid, better compatibility with older Glib versions, minor documentation updates and updated translations.
