Added

• Support for per-element min/max values. This supercedes the existing scalar

  removed in a future version of dm_env_rpc.
• Initial set of compliance tests that environment authors can use to better
  ensure their implementations adhere to the protocol specification.
• Support for dm_env DiscreteArray specs.

Changed

• dm_env_rpc EnvironmentResponse errors in Python are now raised as a
  custom, DmEnvRpcError exception.
