+- the `warnings` field in `getblockchaininfo`, `getmininginfo` and
+  `getnetworkinfo` now returns all the active node warnings as an array
+  of strings, instead of just a single warning. The current behaviour
+  can temporarily be restored by running bitcoind with configuration
+  option `-deprecatedrpc=warnings`.
