 # CHANGELOG
 
-## v0.30.1 - _January 18, 2018_
+## v0.31.0 - _January 30, 2018_
+
+    * Add the `shouldAddPersonalMessagePrefix` parameter to `signOrderHashAsync` so that the
+    caller can decide on whether to add the personalMessage prefix before relaying the request
+    to the signer. Parity Signer, Ledger and TestRPC add the prefix themselves, Metamask expects
+    it to have already been added. (#349)
+
+## v0.30.2 - _January 29, 2018_
+
+    * Add Rinkeby testnet addresses to artifacts  (#337)
+    * Move @0xproject/types to dependencies from devDependencies fixing missing type errors
+
+## v0.30.1 - _January 24, 2018_
 
     * Fix a bug allowing negative fill values  (#212)
     * Fix a bug that made it impossible to pass a custom ZRX address  (#341)

 ### Endpoints
 
+`GET /ping`
+
+Returns `pong`
+
+`GET /info`
+
+Returns a JSON payload describing the state of the queues for each network. For example:
+
+```json
+{
+    "3": {
+        "ether": {
+            "full": false,
+            "size": 4
+        },
+        "zrx": {
+            "full": false,
+            "size": 6
+        }
+    },
+    "42": {
+        "ether": {
+            "full": false,
+            "size": 8
+        },
+        "zrx": {
+            "full": false,
+            "size": 20
+        }
+    }
+}
+```
+
 `GET /ether/:recipient`
 
-Where recipient_address is a hex encoded Ethereum address prefixed with `0x`.
+Where recipient is a hex encoded Ethereum address prefixed with `0x`.
 
 `GET /zrx/:recipient`
 
-Where recipient_address is a hex encoded Ethereum address prefixed with `0x`.
+Where recipient is a hex encoded Ethereum address prefixed with `0x`.
+
+#### Parameters
+
+The endpoints `/ether` and `/zrx` take a query parameter named `networkId` to specify the desired network where you would like to receive the ETH or ZRX. For example:
+
+```bash
+curl -i http://localhost:3000/ether/0x14e2F1F157E7DD4057D02817436D628A37120FD1\?networkId=3
+```
+
+This command will request the local server to initiate a transfer of 0.1 ETH from the dispensing address to `0x14e2F1F157E7DD4057D02817436D628A37120FD1` on the Ropsten testnet.
+
+If no `networkId` is provided via query parameters the faucet will default to network 42 (Kovan)
