I'm getting this with console consumer in the binary package which
seems to be because it was built under Java 7. Can we stick to 6?
Exception in thread "main" java.lang.UnsupportedClassVersionError:
kafka/javaapi/consumer/ConsumerConnector : Unsupported major.minor version 51.0

Other minor comments:
- I don't think the SBT license needs to be included in the binary
package (at the end of LICENSE).
- Would prefer that the release notes remove jiras that were resolved
as won't fix - e.g., the go client jiras.
Thanks again for doing this.
