Subject Re: [ANNOUNCE] Apache HBase 0.98.0 is now available for download
Date Mon, 17 Feb 2014 10:15:21 GMT
Hi,

There is a CHANGES.txt file into the archive, but it doesn't seems to be
accurate. You will be able to retrieve the list of fixed JIRAs by filtering
them from the jira web site using the version.
