+* The Protocol Buffers interface when returning `RpbErrorResp` responses to the client will set the `errcode` field to `0`, whereas before it was `1` or unset. Only client libraries that previously attempted to apply meaning to the `errcode` field will be affected. Improvement of the error responses from Protocol Buffers is planned for the next major release.
+* Some spurious messages may be sent to the log after a Pipe-based MapReduce job sent via PBC has been shutdown. This does not affect normal operations. [basho/riak_kv#366](https://github.com/basho/riak_kv/issues/366)
