+<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 Solr tutorial at <a href="https://lucene.apache.org/solr/guide/solr-tutorial.html">https://lucene.apache.org/solr/guide/solr-tutorial.html</a>
+</p>
+<h2><a id="v8.0.0" href="javascript:toggleList('v8.0.0')">Release 8.0.0 </a></h2>
+<ul id="v8.0.0.list">

+ <ol id="v8.0.0.upgrade_notes.list">
+ <li>Due to the introduction of LIR redesign since Solr 7.3 (<a href="http://issues.apache.org/jira/browse/SOLR-11702">SOLR-11702</a>) and the removing of old LIR implementation in Solr 8.
+Rolling updates are not possible unless all nodes must be on Solr 7.3 or higher. If not updates can be lost.
+<p/>
+</li>
+ <li>Solr nodes can now listen and serve HTTP/2 requests. Most of internal requests (sent by UpdateShardHandler, HttpShardHandler)
+Http2SolrClient is used. Since by default, internal requests are sent by using HTTP/2,
+Solr 8.0 nodes can't talk to old nodes (7.x). However we can follow these steps to do rolling updates:
+<ul class="bulleted-list">
+<li class="bulleted-list">
+Do rolling updates as normally, but the Solr 8.0 nodes must start with -Dsolr.http1=true as startup parameter.
+ By using this parameter internal requests are sent by using HTTP/1.1
+</li>
+<li class="bulleted-list">
+When all nodes are upgraded to 8.0, restart them, this time -Dsolr.http1 parameter should be removed.
+</li>
+</ul>
+<p/>
+</li>
+ <li>ALPN is not supported in Java 8 or lower version therefore when a node started in Java 8 or a lower version with SSL enabled,
+it will send and can only be able to handle HTTP/1.1 requests. In case of using SSL Java 9 or latter versions are recommended.
+<p/>
+</li>
+ <li>Custom AuthenticationPlugin must provide its own setup for Http2SolrClient through
+implementing HttpClientBuilderPlugin.setup, if not internal requests can't be authenticated.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/LUCENE-7996">LUCENE-7996</a>: The 'func' query parser now returns scores that are equal to 0
+when a negative value is produced. This change is due to the fact that
+Lucene now requires scores to be positive.
+<br /><span class="attrib">(Adrien Grand)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-11882">SOLR-11882</a>: SolrMetric registries retained references to SolrCores when closed. A
+change of SolrMetricMAnager.registerGauge and SolrMetricProducer.initializeMetrics
+method signatures was required to fix it. Third party components that use this API
+need to be updated.
+<br /><span class="attrib">(Eros Taborelli, Erick Erickson, ab)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/LUCENE-8267">LUCENE-8267</a>: Memory codecs have been removed from the codebase (MemoryPostings,
+MemoryDocValues). If you used postingsFormat="Memory" or docValuesFormat="Memory"
+then either remove it to use the default or experiment with one of the others.
+<br /><span class="attrib">(Dawid Weiss)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12586">SOLR-12586</a>: The date format patterns used by ParseDateFieldUpdateProcessorFactory (present in "schemaless mode")
+are now interpreted by Java 8's java.time.DateTimeFormatter instead of Joda Time. The pattern language is very
+similar but not the same. Typically, simply update the pattern by changing an uppercase 'Z' to lowercase 'z' and
+that's it. For the current recommended set of patterns in schemaless mode, see "Schemaless Mode" in the ref guide,
+or simply examine the default configSet. Also note that the set of patterns (formats) here have
+expanded from before to subsume those patterns previously handled by the "extract" contrib (Solr Cell / Tika).
+<br /><span class="attrib">(David Smiley, Bar Rotstein)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12593">SOLR-12593</a>: The "extraction" contrib (Solr Cell) no longer does any date parsing, and thus no longer has the
+"date.formats" configuration. To ensure date strings are properly parsed, use ParseDateFieldUpdateProcessorFactory
+(an URP) commonly registered with the name "parse-date" in "schemaless mode".
+<br /><span class="attrib">(David Smiley, Bar Rotstein)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12643">SOLR-12643</a>: Since Http2SolrClient does not support exposing connections related metrics. These metrics are no longer
+available 'QUERY.httpShardHandler.{availableConnections, leasedConnections, maxConnections, pendingConnections}',
+'UPDATE.updateShardHandler.{availableConnections, leasedConnections, maxConnections, pendingConnections}'
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12605">SOLR-12605</a>: UpdateShardHandler's updateOnlyClient is now a Http2SolrClient (previous HttpSolrClient). This new
+client does not support 'maxConnections','maxConnectionsPerHost' parameters.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12640">SOLR-12640</a>: HttpShardHandlerFactory's defaultClient is now a Http2SolrClient (previous HttpSolrClient). This new
+client does not support 'maxConnections','maxConnectionsPerHost' parameters. LBHttpSolrClient.Req and LBHttpSolrClient.Rsp
+are marked as deprecated, uses LBSolrClient.Req and LBSolrClient.Rsp instead.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12754">SOLR-12754</a>: The UnifiedHighlighter hl.weightMatches now defaults to true. If there are unforseen highlight problems,
+this may be the culprit.
+<p/>
+</li>
+ <li>If you explicitly use BM25SimilarityFactory in your schema, the absolute scoring will be lower due to <a href="http://issues.apache.org/jira/browse/SOLR-13025">SOLR-13025</a>.
+But ordering of documents will not change in the normal case. Use LegacyBM25SimilarityFactory if you need to force
+the old 6.x/7.x scoring. Note that if you have not specified any similarity in schema or use the default
+SchemaSimilarityFactory, then LegacyBM25Similarity is automatically selected for 'luceneMatchVersion' < 8.0.0.
+See also explanation in Reference Guide chapter "Other Schema Elements".
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12535">SOLR-12535</a>: Solr no longer accepts index time boosts in JSON provided to Solr. This used to be provided like so:
+{'id':'1', 'val_s':{'value':'foo', 'boost':2.0}} but will now produce an error. A object/map structure will now only
+be interpreted as a child document or an atomic update; nothing else. A uniqueKey is currently required on all child
+documents to be interpreted as such, though this may change in the future.
+<br /><span class="attrib">(David Smiley)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12633">SOLR-12633</a>: When JSON data is sent to Solr with nested child documents split using the "split" parameter, the child
+docs will now be associated to their parents by the field/label string used in the JSON instead of anonymously. Most
+users probably won't notice the distinction since the label is lost any way unless special fields are in the schema.
+This choice used to be toggleable with an internal/expert "anonChildDocs" parameter flag which is now gone.
+<br /><span class="attrib">(David Smiley)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-11774">SOLR-11774</a>: In 'langid' contrib, the LanguageIdentifierUpdateProcessor base class changed some method signatures.
+If you have a custom language identifier implementation you will need to adapt your code.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-9515">SOLR-9515</a>: Hadoop dependencies have been upgraded to Hadoop 3.2.0 from 2.7.2.
+<br /><span class="attrib">(Mark Miller, Kevin Risden)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-5211">SOLR-5211</a>: Deleting (or updating) documents by their uniqueKey is now scoped to only consider root documents, not
+child/nested documents. Thus a delete-by-id won't work on a child doc (no-op), and an attempt to update a child doc
+by providing a new doc with the same ID would add a new doc (probably erroneous). Both these actions were and still
+are problematic. In-place-updates are safe though. If you want to delete certain child documents and if you know
+they don't themselves have nested children then you must do so with a delete-by-query technique.
+<p/>
+</li>

+ <ol id="v8.0.0.new_features.list">
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12591">SOLR-12591</a>: Expand the set of recognized date format patterns of schemaless mode to subsume those handled by the
+"extract" contrib (Solr Cell / Tika). This is primarily a change in configuration of the default configSet for more
+patterns, but also included enabling "lenient" parsing in ParseDateFieldUpdateProcessorFactory. The default
+locale was changed from ROOT to en_US since well-known patterns assume this locale.
+<br /><span class="attrib">(David Smiley, Bar Rotstein)</span></li>

+it. The [child] (doc transformer) will return a hierarchy with relationships; no params needed. The relationship
+path is indexed for use in queries (can be disabled if not needed). Also, child documents needn't provide a uniqueKey

+ZK as well as written using the V2 set-obj-property syntax but it is deprecated and will be removed in Solr 9.

+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12739">SOLR-12739</a>: Autoscaling policy framework is now used as the default strategy to select the nodes on which
+new replicas or replicas of new collections are created. Previously, the maxShardsPerNode parameter was not allowed
+on collections when autoscaling policy was configured. Also if an autoscaling policy was configured then the default
+was to set an unlimited maxShardsPerNode automatically. Now the maxShardsPerNode parameter is always
+allowed during collection creation and maxShardsPerNode should be set correctly (if required) regardless of whether
+autoscaling policies are in effect or not. The default value of maxShardsPerNode continues to be 1 as before. It can
+be set to -1 during collection creation to fall back to the old behavior of unlimited maxShardsPerNode when using
+autoscaling policy.
