+<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 class="bulleted-list">

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

+ <ol id="v6.1.0.new_features.list">
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-8782">SOLR-8782</a>: Add asynchronous sugar methods to the SolrJ Collections API. You
+can now call .processAsync() to run a method asynchronously, or
+.processAndWait() to wait for a call to finish without holding HTTP
+collections open.
+<br /><span class="attrib">(Alan Woodward)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-8765">SOLR-8765</a>: Enforce required parameters at query construction time in the SolrJ
+Collections API, add static factory methods, and deprecate old setter methods.
+<br /><span class="attrib">(Alan Woodward, Jason Gerlowski)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-8842">SOLR-8842</a>: authorization APIs do not use name as an identifier for a permission

+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:
+ &fl=[geo f=<your geometry field> w=(GeoJSON|WKT|POLY)]
+The default format is GeoJSON. For information on the supported formats, see:
+<a href="https://github.com/locationtech/spatial4j/blob/master/FORMATS.md">https://github.com/locationtech/spatial4j/blob/master/FORMATS.md</a>

+TransformContext was rendered redundant and was removed.
+<br /><span class="attrib">(yonik)</span></li>
+ <li>Several changes have been made regarding the "Similarity" used in Solr, in order to provide
+better default behavior for new users. There are 3 key impacts of these changes on existing
+users who upgrade:
+</li>
+ <li>DefaultSimilarityFactory has been removed. If you currently have DefaultSimilarityFactory explicitly
+referenced in your schema.xml, edit your config to use the functionally identical
+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 <similarity/> 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 ( /<collection>/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 :
+<schemaFactory class="ClassicIndexSchemaFactory"/> 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().

+ <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.
+<p/>
+</li>
+ <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
+no more be overridden. If you still wish to override those methods, override the handleRequestBody()

+for more details. The corresponding SolrJ action has also been removed.
+<p/>

+ <li>bin/post now defaults application/json files to the /update/json/docs end-point. Use `-format solr` to force
+files to the /update end-point. See <a href="http://issues.apache.org/jira/browse/SOLR-7042">SOLR-7042</a> for more details.
