+<h1>Apache Solr Release Notes</h1>
+
+<div id="buttons.parent"></div>
+
+<h2>Introduction</h2>
+ <p>Apache Solr is an open source enterprise search server based on the Apache Lucene Java
+search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search,
+caching, replication, and a web administration interface. It runs in a Java
+servlet container such as Jetty.
+</p>
+ <p>See <a href="http://lucene.apache.org/solr">http://lucene.apache.org/solr</a> for more information.
+</p>
+<h2>Getting Started</h2>
+ <p>You need a Java 1.6 VM or later installed.
+In this release, there is an example Solr server including a bundled
+servlet container in the directory named "example".
+See the tutorial at <a href="http://lucene.apache.org/solr/tutorial.html">http://lucene.apache.org/solr/tutorial.html</a>

+ <li>XML configuration parsing is now more strict about situations where a single
+setting is allowed but multiple values are found. In the past, one value
+would be chosen arbitrarily and silently. Starting with 4.5, configuration
+parsing will fail with an error in situations like this. If you see error
+messages such as "solrconfig.xml contains more than one value for config path:
+XXXXX" or "Found Z configuration sections when at most 1 is allowed matching
+expression: XXXXX" check your solrconfig.xml file for multiple occurrences of
+XXXXX and delete the ones that you do not wish to use. See <a href="http://issues.apache.org/jira/browse/SOLR-4953">SOLR-4953</a> &
+<a href="http://issues.apache.org/jira/browse/SOLR-5108">SOLR-5108</a> for more details.
+<p/>
+</li>
+ <li>In the past, schema.xml parsing would silently ignore "default" or "required"
+options specified on <dynamicField/> declarations. Begining with 4.5, attempting
+to do configured these on a dynamic field will cause an init error. If you
+encounter one of these errors when upgrading an existing schema.xml, you can
+safely remove these attributes, regardless of their value, from your config and
+Solr will continue to bahave exactly as it did in previous versions. See
+<a href="http://issues.apache.org/jira/browse/SOLR-5227">SOLR-5227</a> for more details.
+<p/>
+</li>
+ <li>The UniqFieldsUpdateProcessorFactory has been improved to support all of the
+FieldMutatingUpdateProcessorFactory selector options. The <lst named="fields">
+init param option is now deprecated and should be replaced with the more standard
+<arr name="fieldName">. See <a href="http://issues.apache.org/jira/browse/SOLR-4249">SOLR-4249</a> for more details.
+<p/>
+</li>
+ <li>UpdateRequestExt has been removed as part of <a href="http://issues.apache.org/jira/browse/SOLR-4816">SOLR-4816</a>. You should use UpdateRequest
+instead.
+<p/>
+</li>
+ <li>CloudSolrServer can now use multiple threads to add documents by default. This is a
+small change in runtime semantics when using the bulk add method - you will still
+end up with the same exception on a failure, but some documents beyond the one that
+failed may have made it in. To get the old, single threaded behavior, set parallel updates
+to false on the CloudSolrServer instance.
