 ## News
 ### 21 May 2018 : release 3.0.0 available
-This release works with Hadoop 3.x.y
+This release works with Hadoop 3.x.y. 
+The on-disk layout of Acid tables has changed with this release. Any Acid table partition that had Update/Delete/Merge statement executed since the last Major compaction must execute Major compaction before upgrading to 3.0.  No more Update/Delete/Merge may be executed against these tables since the start of Major compaction.  Not following this may lead to data corruption.  Tables/partitions that only contain results of Insert statements are fully compatible and don't need to be compacted.
 You can look at the complete [JIRA change log for this release][HIVE_3_0_0_CL].
