+<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.
+</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 1.8 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 Quick Start guide at <a href="http://lucene.apache.org/solr/quickstart.html">http://lucene.apache.org/solr/quickstart.html</a>
+</p>
+<h2><a id="v6.1.0" href="javascript:toggleList('v6.1.0')">Release 6.1.0 </a></h2>
+<ul id="v6.1.0.list">
+      <li>Upgrading from Solr any prior release
+<ul class="bulleted-list">

+      <li>* If you use historical dates, specifically on or before the year 1582, you should re-index.

+      <li><a href="http://issues.apache.org/jira/browse/SOLR-8782">SOLR-8782</a>: Add asynchronous sugar methods to the SolrJ Collections API.  You

+Will return a FeatureCollection for each SolrDocumentList and a Feature with the
+requested geometry for each SolrDocument.  The requested geometry field needs
+to either extend AbstractSpatialFieldType or store a GeoJSON string.  This also adds
+a [geo] DocumentTransformer that can return the Shape in a variety of formats:
+  &amp;fl=[geo f=&lt;your geometry field&gt; w=(GeoJSON|WKT|POLY)]
+The default format is GeoJSON.  For information on the supported formats, see:

+ClassicSimilarityFactory.  See <a href="http://issues.apache.org/jira/browse/SOLR-8239">SOLR-8239</a> for more details.
+</li>
+      <li>The implicit default Similarity used when no &lt;similarity/&gt; is configured in schema.xml has
+been changed to SchemaSimilarityFactory.  Users who wish to preserve back-compatible behavior should
+either explicitly configure ClassicSimilarityFactory, or ensure that the luceneMatchVersion
+for the collection is less then 6.0.  See <a href="http://issues.apache.org/jira/browse/SOLR-8270">SOLR-8270</a> + <a href="http://issues.apache.org/jira/browse/SOLR-8271">SOLR-8271</a> for details.
+</li>
+      <li>SchemaSimilarityFactory has been modified to use BM25Similarity as the default for fieldTypes that
+do not explicitly declare a Similarity.  The legacy behavior of using ClassicSimilarity as the
+default will occur if the luceneMatchVersion for the collection is less then 6.0, or the
+'defaultSimFromFieldType' configuration option may be used to specify any default of your choosing.
+See <a href="http://issues.apache.org/jira/browse/SOLR-8261">SOLR-8261</a> + <a href="http://issues.apache.org/jira/browse/SOLR-8329">SOLR-8329</a> for more details.
+<p/>
+</li>
+      <li>If your solrconfig.xml file doesn't explicitly mention the schemaFactory to use then Solr will choose
+the ManagedIndexSchemaFactory by default. Previously it would have chosen ClassicIndexSchemaFactory.
+This means that the Schema APIs ( /&lt;collection&gt;/schema ) are enabled and the schema is mutable.
+When Solr starts your schema.xml file will be renamed to managed-schema. If you want to retain the old behaviour
+then please ensure that the solrconfig.xml explicitly uses the ClassicIndexSchemaFactory :
+&lt;schemaFactory class="ClassicIndexSchemaFactory"/&gt; or your luceneMatchVersion in the solrconfig.xml is less than 6.0
+<p/>
+</li>
+      <li>SolrIndexSearcher.QueryCommand and QueryResult were moved to their own classes. If you reference them
+in your code, you should import them under o.a.s.search (or use your IDE's "Organize Imports").
+<p/>
+</li>
+      <li><a href="http://issues.apache.org/jira/browse/SOLR-8698">SOLR-8698</a>: 'useParams' attribute specified in request handler cannot be overridden from request params
+<p/>
+</li>
+      <li>When requesting stats in date fields, "sum" is now a double value instead of a date. See <a href="http://issues.apache.org/jira/browse/SOLR-8671">SOLR-8671</a>
+<p/>
+</li>
+      <li><a href="http://issues.apache.org/jira/browse/SOLR-8736">SOLR-8736</a>: The deprecated GET methods for schema are now accessible through the bulk API. The output
+has less details and is not backward compatible.
+<p/>
+</li>
+      <li>In the past, Solr guaranteed that retrieval of multi-valued fields would preserve the order of values.
+Because values may now be retrieved from column-stored fields (docValues="true"), in conjunction with the
+fact that docValues do not currently preserve order, means that users should set useDocValuesAsStored="false"
+to prevent future optizations from using the column-stored values over the row-stored values when
+fields have both stored="true" and docValues="true".
+<p/>
+</li>
+      <li>Formatted date-times from Solr have some differences. If the year is more than 4 digits, there is a leading '+'.
+When there is a non-zero number of milliseconds, it is padded with zeros to 3 digits. Negative year (BC) dates are
+now possible.  Parsing: It is now an error to supply a portion of the date out of its, range, like 67 seconds.
+<p/>
+</li>
+      <li>SolrJ no longer includes DateUtil. If for some reason you need to format or parse dates, simply use Instant.format()
+and Instant.parse().
+<p/>

+    <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.

+      <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

+Lucene includes a queryparser that supports the creation of Lucene queries from XML.
+The queries supported by lucene.queryparser.xml.CoreParser are now supported by the newly
+created solr.search.SolrCoreParser and in future SolrCoreParser could support additional
+queries also.
+Example: &lt;BooleanQuery fieldName="description"&gt;
+           &lt;Clause occurs="must"&gt; &lt;TermQuery&gt;shirt&lt;/TermQuery&gt; &lt;/Clause&gt;
+           &lt;Clause occurs="mustnot"&gt; &lt;TermQuery&gt;plain&lt;/TermQuery&gt; &lt;/Clause&gt;
+           &lt;Clause occurs="should"&gt; &lt;TermQuery&gt;cotton&lt;/TermQuery&gt; &lt;/Clause&gt;
+           &lt;Clause occurs="must"&gt;
+             &lt;BooleanQuery fieldName="size"&gt;
