Upgrading from Solr 5.1
-----------------------
* A bug was introduced in Solr 4.10 that caused index time document boosts to trigger excessive field
boosts in multivalued fields -- the result being that some field norms might be excessively large.
This bug has now been fixed, but users of document boosts are strongly encouraged to re-index.
See SOLR-7335 for more details.
* The Slice and Replica classes have been changed to use State enums instead of string constants
to track the respective stats. Advanced users with client code manipulating these objects will
need to update their code accordingly. See SOLR-7325 and SOLR-7336 for more info.
