+<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="v6.3.0" href="javascript:toggleList('v6.3.0')">Release 6.3.0 </a></h2>
+<ul id="v6.3.0.list">
+ <li>Consult the <a href="http://lucene.apache.org/core/6_3_0/changes/Changes.html">LUCENE_CHANGES.txt</a> file for additional, low level, changes in this release.
+</li>
+ </li>
+ <li><a id="v6.3.0.versions_of_major_components" href="javascript:toggleList('v6.3.0.versions_of_major_components')">Versions of Major Components</a> (6)
+ <ol id="v6.3.0.versions_of_major_components.list">
+ <li>Apache Tika 1.13
+</li>
+ <li>Carrot2 3.12.0
+</li>
+ <li>Velocity 1.7 and Velocity Tools 2.0
+</li>
+ <li>Apache UIMA 2.3.1
+</li>
+ <li>Apache ZooKeeper 3.4.6

+ <h3>Detailed Change List</h3>
+ <li><a id="v6.3.0.upgrade_notes" href="javascript:toggleList('v6.3.0.upgrade_notes')">Upgrade Notes</a> (6)
+ <ol id="v6.3.0.upgrade_notes.list">
+ <li>If you use the JSON Facet API (json.facet) with method=stream, you must now set sort='index asc' to get the streaming
+behavior; otherwise it won't stream. Reminder: "method" is a hint that doesn't change defaults of other parameters.
+<p/>
+</li>
+ <li>If you use the JSON Facet API (json.facet) to facet on a numeric field and if you use mincount=0 or if you set the
+prefix, then you will now get an error as these options are incompatible with numeric faceting.
+<p/>
+</li>
+ <li>Solr's logging verbosity at the INFO level has been greatly reduced, and
+you may need to update the log configs to use the DEBUG level to see all the
+logging messages you used to see at INFO level before.
+<p/>
+</li>
+ <li>We are no longer backing up solr.log and solr_gc.log files in date-stamped copies forever. If you relied on
+the solr_log_<date> or solr_gc_log_<date> being in the logs folder that will no longer be the case.
+See <a href="http://issues.apache.org/jira/browse/SOLR-9570">SOLR-9570</a> for details.
+<p/>
+</li>
+ <li>The create/deleteCollection methods on MiniSolrCloudCluster have been
+deprecated. Clients should instead use the CollectionAdminRequest API. In
+addition, MiniSolrCloudCluster#uploadConfigDir(File, String) has been
+deprecated in favour of #uploadConfigSet(Path, String)
+<p/>
+</li>
+ <li>The bin/solr.in.sh (bin/solr.in.cmd on Windows) is now completely commented by default. Previously, this wasn't so,
+which had the effect of masking existing environment variables.
+<p/>
