+## Updated RPCs
+
+- The `getblock` RPC command now supports verbosity level 3 containing transaction inputs
+  `prevout` information.  The existing `/rest/block/` REST endpoint is modified to contain
+  this information too. Every `vin` field will contain an additional `prevout` subfield
+  describing the spent output. `prevout` contains the following keys:
+  - `generated` - true if the spent coins was a coinbase.
+  - `height`
+  - `value`
+  - `scriptPubKey`
+
