> the first pass version of the upgrade docs has a brief note about the bucket cache changing:
> {quote}
> * hbase.bucketcache.combinedcache.enabled <!-- This seems worth a call out section? -->
> * hbase.bucketcache.ioengine no longer supports the 'heap' value.  <!-- This seems worth a call out section? -->
> {quote}
> But the changes are substantial and warrant a section of their own under the  "Changes of Note!" banner.
