Yes, this release includes a fix for issue 1159<https://code.google.com/p/hypertable/issues/detail?id=1159>. If you're running on top of the local filesystem (e.g. not HDFS), setting the DfsBroker.Local.DirectIO property to *true* can give you better performance because it avoids the double-caching problem of having the same data cached both within the RangeServer and the OS. The last two items are just internal things that don't have any user facing impact.
