flatpak 1.15.3 Build system: * Building this version of Flatpak with Meson is recommended. The source release flatpak-1.15.3.tar.xz no longer contains Autotools-generated files, although this version can still be built using Autotools after running `./autogen.sh`. Future versions are likely to remove the Autotools build system. Bug fixes: * When splitting an upgrade into two steps (download without installing, and then upgrade without allowing further downloads) like GNOME Software does, if an app is marked EOL and superseded by a replacement, don't remove the superseded app in the first step, which would result in the replacement incorrectly not being installed (#5172) * Fix a crash when --socket=gpg-agent is used (#5095) * Fix a crash when listing apps if one of them is broken or misconfigured (#5293) * If an app has invalid syntax in its overrides or metadata, mention the filename in the error message (#5293) * Unset $GDK_BACKEND for apps, ensuring GTK apps with --socket=fallback-x11 can work (#5303) * Fix a deprecation warning when compiled with curl >= 7.85 (#5284) * Translation updates: es, ru (#5266, #5312, #5313) Internal changes: * Better diagnostic messages for why runtimes are or are not considered unused (#5237) Git-EVTag-v0-SHA512: a440a346d1107375245c3013c6b2d044eb187302bc6e4d1db66ec8c7b1a2353ee5b5edf8779d9378ea5c482619c40f003ccd7a3d9825a45f99ae356ac3db2a16
