Description

There are a number of mentions of CDH releases corresponding to Impala version numbers.

Perhaps there is some historical milestone we can use to prune older release note material that isn't relevant in a modern context. For example, maybe all the "new feature", "fixed issue", and "incompatible changes" from the Impala 1.x era are no longer needed in the docs. (This is a recommendation I would probably be making pretty soon regardless of the ASF work.)
