+Deprecated
+----------
+
+As of this release, the following previously deprecated features are disabled
+by default, but may be be reenabled using `-allowdeprecated=<feature>`.
+
+  - The `dumpwallet` RPC method is disabled. It may be reenabled with
+    `allowdeprecated=dumpwallet`. `dumpwallet` should not be used; it is
+    unsafe for backup purposes as it does not return any key information
+    for keys used to derive shielded addresses. Use `z_exportwallet` instead.
