Solr 4.8.0 Release Highlights: * Apache Solr now requires Java 7 or greater (recommended is Oracle Java 7 or OpenJDK 7, minimum update 55; earlier versions have known JVM bugs affecting Solr). * Apache Solr is fully compatible with Java 8. * <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. Please report any feedback to the mailing lists (http://lucene.apache.org/solr/discussion.html)
