 * SOLR-7209: /update/json/docs carry forward fields from previous records (Noble Paul)
 
+* SOLR-7195: Fixed a bug where the bin/solr shell script would incorrectly
+  detect another Solr process listening on the same port number.  If the
+  requested listen port was 8983, it would match on another Solr using port
+  18983 for any purpose.  Also escapes the dot character in all grep commands
+  looking for start.jar.
