   > There is no need for the migration because AutoRepair will automatically 
[purge](https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/repair/autorepair/AutoRepairUtils.java#L826)
 the stale hostId entries.
   
   Even though the old entries are purged the issue is that work will be lost 
if you upgrade mid-repair since repair will be started again from scratch, so 
migrating the entries will ensure that repair state is resumed properly after 
the upgrade.
   
   I added repair history and priority migration on 791e64d, this allows repair 
history and priorities to be resumed after upgrade, so with that we don't need 
a special NEWS.txt entry.
   
   I also updated the tests to check that the entries are migrated properly and 
that repair executes successfully after upgrade, and the priority table is 
migrated as well.
   
   Let me know what you think @jaydeepkumar1984 @tolbertam
