+- Update to 4.8
+  + Compatibility Notice:
+    In order to allow flatpak users to share preferences with
+    installations outside of the sandbox we need to change the
+    preference path from /org/gnucash to /org/gnucash/GnuCash. This
+    release of GnuCash does that and it will automatically migrate
+    existing preferences. It does not, however, continue to write
+    preferences to the old path and it runs the migration only
+    once. If you go back and forth between GnuCash 4.7 and an older
+    versions you'll have two sets of preferences, one for GnuCash
+    4.7 and later and another for GnuCash 4.6 and earlier. This
+    includes the file history list and last-opened file.
+  + Bugfixes
+  + Updated translations.
+- Add 285017793d2c0c9f5a8d52b3db42944480e3f557.patch: Use plain cat
+  instead of cmake -E cat to join the migratable-prefs. Fixes build
+  for everything older than current Tumbleweed.
