Release versioning

[David Arthur]

Just a quick question:

0.8.0 was just released and the next planned release is 0.8.1, and the 
next major set of updates (coordinator, etc) is targeted at 0.9.0. It 
seems like we are using the pattern 0.<major>.<minor> instead of 
<major>.<minor>.<trivial>

So what happens if we have a bugfix release for 0.8.0? Would it bump to 
0.8.0.1?

A good example would be how to fix 
https://issues.apache.org/jira/browse/KAFKA-1174 - the solution probably 
involves bumping the version number.

Cheers
