+## Parity [v1.8.5](https://github.com/paritytech/parity/releases/tag/v1.8.5) (2017-12-29)
+
+Parity 1.8.5 changes the default behavior of JSON-RPC CORS setting, detects same-key engine signers in Aura networks, and updates bootnodes for the Kovan and Foundation networks.
+
+Note: The default value of `--jsonrpc-cors` option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with `--jsonrpc-cors all` or `--jsonrpc-cors http://example.com`.

+
