 Upgrading

+   - If performing a rolling upgrade from 3.0.13, there will be a schema mismatch caused
+     by a bug with the schema digest calculation in 3.0.13. This will cause unnecessary
+     but otherwise harmless schema updates, see CASSANDRA-13559 for more details.
+
+   - Nothing else specific to this release, but please see previous versions upgrading section,
      especially if you are upgrading from 2.2.
