https://wiki.apache.org/solr/ReleaseNote48?action=diff&rev1=10&rev2=11

  
  * Apache Solr is fully compatible with Java 8.
  
- * Solr now allows wildcards inside phrase queries.
- 
- * A new List collections and cluster status API was added which allows
-   clients to read collection and shard information instead of reading
-   data directly from ZooKeeper.
- 
- * Various new reconfigureable analysis factories were added:
-   stopword filters, synonym filters
- 
  * <fields> and <types> tags have been deprecated from schema.xml.
    There is no longer any reason to keep them in the schema file,
    they may be safely removed. This allows intermixing of <fieldType>,
    <field> and <copyField> definitions if desired.
+ 
+ * The new {!complexphrase} query parser supports wildcards, ORs etc.
+   inside Phrase Queries. 
+ 
+ * New Collections API CLUSTERSTATUS action reports the status of
+   collections, shards, and replicas, and also lists collection
+   aliases and cluster properties.
+  
+ * Added managed synonym and stopword filter factories, which enable
+   synonym and stopword lists to be dynamically managed via REST API.
+ 
+ * JSON updates now support nested child documents, enabling {!child}
+   and {!parent} block join queries. 
+ 
+ * Added ExpandComponent to expand results collapsed by the
+   CollapsingQParserPlugin, as well as the parent/child relationship
+   of nested child documents.
+ 
+ * Long-running Collections API tasks can now be executed
+   asynchronously; the new REQUESTSTATUS action provides status.
+ 
+ * Added a hl.qparser parameter to allow you to define a query parser
+   for hl.q highlight queries.
+ 
+ * In Solr single-node mode, cores can now be created using named
+   configsets.
+ 
+ * New DocExpirationUpdateProcessorFactory supports computing an
+   expiration date for documents from the "TTL" expression, as well as
+   automatically deleting expired documents on a periodic basis. 
  
  Solr 4.8.0 also includes many other new features as well as numerous
  optimizations and bugfixes of the corresponding Apache Lucene release.
