+=== Settings changes
+
+==== Snapshot settings
+
+The internal setting `cluster.routing.allocation.snapshot.relocation_enabled` that allowed shards with running snapshots to be reallocated to
+different nodes has been removed. Enabling this setting could cause allocation issues if a shard got allocated off a node and then
+reallocated back to this node while a snapshot was running.
