+Read before updating
+--------------------
+
+1. Information for Audio users that are using an external Lavalink instance (if you don't know what that is, you should skip this point):
+
+    Red 3.4.8 uses a new Lavalink jar that you will need to manually update from `our GitHub <https://github.com/Cog-Creators/Lavalink-Jars/releases/tag/3.3.2.3_1212>`__.
+
+2. Fedora 31 and OpenSUSE Leap 15.1 are no longer supported as they have already reached end of life.
