File 0015-Support-multiple-versions-in-required-flatpak-metadata-key.patch of Package flatpak.14328
From e66c9ed56c4205380c232e1319a7d848c9b4e925 Mon Sep 17 00:00:00 2001 From: Alexander Larsson <alexl@redhat.com> Date: Wed, 18 Sep 2019 16:21:55 +0200 Subject: [PATCH] Support multiple versions in required-flatpak metadata key Support a list of versions that are supported. This will be useful for e.g. the extra_data for extensions once that is backported to 1.2, because that will require it to say that it is supported for > 1.2.5 in the 1.2 series and > 1.4.2 otherwise.
