0.8.3

Breaking Change to JSON RPC-API

From v0.8.3, incoming HTTP requests are only accepted from hostnames specified using the --host-whitelist command-line option. If not specified, the default value for --host-whitelist is localhost.

If using the URL http://127.0.0.1 to make JSON-RPC calls, use --host-whitelist to specify the hostname 127.0.0.1 or update the hostname to localhost.

If your application publishes RPC ports, specify the hostnames when starting Pantheon. For example:

pantheon --host-whitelist=example.com

Specify * or all for --host-whitelist to effectively disable host protection and replicate pre-v0.8.3 behavior. This is not recommended for production code.
