+title: Rename `state_version` in `RuntimeVersion` to `system_version`.
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      This PR renames `state_version` in `RuntimeVersion` to `system_version`. `system_version=2` signifies
+      that extrinsic root derivation uses `StateVersion::V1`.
+
+  - audience: Runtime User
+    description: |
+      `RuntimeVersion`'s `state_version` is renames to `system_version`. Applications using that type and its field
+      must update their code to reflect the changes
