+<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="v8.4.0" href="javascript:toggleList('v8.4.0')">Release 8.4.0 </a></h2>
+<ul id="v8.4.0.list">
+ <li>Consult the <a href="https://lucene.apache.org/core/8_4_0/changes/Changes.html">LUCENE_CHANGES.txt</a> file for additional, low level, changes in this release.

+ <li>Apache Tika 1.19.1
+</li>
+ <li>Carrot2 3.16.0
+</li>
+ <li>Velocity 2.0 and Velocity Tools 3.0
+</li>
+ <li>Apache ZooKeeper 3.5.5

+ <ol id="v8.4.0.upgrade_notes.list">
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13823">SOLR-13823</a>: org.apache.solr.search.grouping.distributed.command.QueryCommand.Builder has new method 'setMainQuery' which is used
+to set top-level query. build() would fail if called without setting mainQuery.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13817">SOLR-13817</a>: Deprecate legacy SolrCache implementations. Users are encouraged to transition their
+configurations to use org.apache.solr.search.CaffeineCache instead.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13982">SOLR-13982</a>: Some security-related http headers such as Content-Security-Policy are now set. If you have custom html served
+up by Solr's http server that contains inline javascript, it will no longer execute in modern browsers. You can fix your JS
+code to not run inline anymore, or edit etc/jetty.xml and weaken the CSP, or remove/alter the headers with a reverse proxy.
+<br /><span class="attrib">(rmuir)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13806">SOLR-13806</a>: QueryResponse.getExplainMap() type has changed from Map<String, String> to Map<String, Object>
+in order to accommodate structured explanations. This is a partially back-compatible change - compiled
+third-party components will work the same as before due to type erasure but source code changes may be
+required.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-14025">SOLR-14025</a>: VelocityResponseWriter has been hardened - only trusted configsets can render configset provided
+templates and rendering templates from request parameters has been removed.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13904">SOLR-13904</a>: timeAllowed parameter is allowed to have 0 value
+<br /><span class="attrib">(Houston Putman, Mikhail Khludnev)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13970">SOLR-13970</a>: Using Collapse filter or expand component with grouping is explicitly disallowed as the combination
+would cause inconsistent behavior and NPEs.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13978">SOLR-13978</a>: The default configset no longer has the following:
+<ul class="bulleted-list">
+<li class="bulleted-list">
+Library inclusions (<lib ../>) for extraction, solr-cell libs, clustering, velocity, LTR and language identifier
+</li>
+<li class="bulleted-list">

+<li class="bulleted-list">
+XSLT response writer
+</li>
+<li class="bulleted-list">
+Velocity response writer
+</li>
+</ul>
+If you want to use them in your collections, please add them to your configset manually or through the Config APIs.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-14071">SOLR-14071</a>: Untrusted configsets (ones that are uploaded via unsecured configset API) cannot use <lib> directive.
+Consider enabling authentication/authorization so that the uploaded configsets are trusted.
+Note: If you already have a collection using untrusted configset that uses <lib> directive, it will not load after
+upgrading to 8.4. You can re-upload your configset using "bin/solr zk -upconfig .." or place your libraries in the
+classpath and restart Solr.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-14065">SOLR-14065</a>: VelocityResponseWriter has been deprecated and may be removed in a future version.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-14072">SOLR-14072</a>: The "Blob Store" API and "runtimeLib" plugin mechanism that uses it is now considered deprecated. The
+replacement to it is the "Package Management" system, which includes a "File Store". These are experimental currently
+but will grow/stabalize/mature.

+ <li>Solr's default behavior when dealing with 'maxBooleanClauses' has changed to reduce the risk of exponential
+query expansion when dealing with pathological query strings. A default upper limit of 1024 clauses
+(The same default prior to Solr 7.0) is now enforced at the node level, and can be overridden in solr.xml.
+The identically named solrconfig.xml setting is still available for limiting the size of 'explicit' boolean
+query strings, but this per-collection limit is still ristricted by the upper-bound of the global limit
+in solr.xml. See <a href="http://issues.apache.org/jira/browse/SOLR-13336">SOLR-13336</a> for more details.
+<p/>

+ <li>When requesting the status of an async request via REQUESTSTATUS collections API, the response will
+include the list of internal async requests (if any) in the "success" or "failed" keys (in addition
+to them being included outside those keys for backwards compatibility). See <a href="http://issues.apache.org/jira/browse/SOLR-12708">SOLR-12708</a> for more
