+ <ol id="v5.5.0.upgrading_from_solr_5.4.list">
+ <li>The Solr schema version has been increased to 1.6. Since schema version 1.6, all non-stored docValues fields
+will be returned along with other stored fields when all fields (or pattern matching globs) are specified
+to be returned (e.g. fl=*) for search queries. This behavior can be turned on and off by setting
+'useDocValuesAsStored' parameter for a field or a field type to true (default since schema version 1.6)
+or false (default till schema version 1.5).
+Note that enabling this property has performance implications because DocValues are column-oriented and may
+therefore incur additional cost to retrieve for each returned document. All example schema are upgraded to
+version 1.6 but any older schemas will default to useDocValuesAsStored=false and continue to work as in
+older versions of Solr. If this new behavior is desirable, then you should set version attribute in your
+schema file to '1.6'. Re-indexing is not necessary to upgrade the schema version.
+Also note that while returning non-stored fields from docValues (default in schema versions 1.6+, unless
+useDocValuesAsStored is false), the values of a multi-valued field are returned in sorted order.
+If you require the multi-valued fields to be returned in the original insertion order, then make your
+multi-valued field as stored. This requires re-indexing.
+See <a href="http://issues.apache.org/jira/browse/SOLR-8220">SOLR-8220</a> for more details.
+<p/>
+</li>
+ <li>All protected methods from CoreAdminHandler other than handleCustomAction() is removed by <a href="http://issues.apache.org/jira/browse/SOLR-8476">SOLR-8476</a> and can
+no more be overridden. If you still wish to override those methods, override the handleRequestBody()

+for more details. The corresponding SolrJ action has also been removed.
+<p/>
+</li>
+ <li>bin/post now defaults application/json files to the /update/json/docs end-point. Use `-format solr` to force
+files to the /update end-point. See <a href="http://issues.apache.org/jira/browse/SOLR-7042">SOLR-7042</a> for more details.
