+
+<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.

+ <ol id="v5.3.0.upgrading_from_solr_5.2.list">
+ <li>SolrJ's CollectionAdminRequest class is now marked as abstract. Use one of its concrete
+sub-classes instead.
+<p/>
+</li>
+ <li>Solr no longer supports forcefully unlocking an index.
+This is no longer supported by the underlying Lucene locking
+framework. The setting in solrconfig.xml has no effect anymore.
+Background: If you use native lock factory, unlocking should
+not be needed, because the locks are cleared after process
+shutdown automatically by the operating system. If you are
+using simple lock factory (not recommended) or hdfs lock
+factory, you may need to manually unlock by deleting the lock
+file from filesystem / HDFS.
+<p/>
+</li>
+ <li>The zkCredientialsProvider element in solrcloud section of solr.xml is now deprecated.
+Use the correct spelling (zkCredentialsProvider) instead.
+<p/>
+</li>
+ <li>class TransformerWithContext is deprecated . Use DocTransformer directly
+<p/>
+</li>
+ <li>The "name" parameter in ADDREPLICA Collections API call has be deprecated. One cannot specify
+the core name for a replica. See <a href="http://issues.apache.org/jira/browse/SOLR-7499">SOLR-7499</a> for more info.
+<p/>
+</li>
+ <li>The ShardHandler interface has changed. The interface used to provide a
+`checkDistributed` function which doubled up in purpose to determine if the
+request is distributed, and to prepare for distributed requests. This unfortunately
+meant that the object had to be instantiated even when the request is not
+distributed. The task of initially determining if the request is distributed
+is now done by SearchHandler using the distrib/shards parameters, and a
+ShardHandler object is created only if the request is distributed. The interface
+now has a `prepDistributed` function instead of the `checkDistributed` function,
+which can then be used to prepare for the distributed request. Users with custom
+ShardHandler implementations would need to modify their code to this effect.
+<p/>
+</li>
+ <li>The system property "solr.solrxml.location" is not supported any more. Now, solr.xml is first
+looked up in zookeeper, and if not found, fallback to SOLR_HOME. See <a href="http://issues.apache.org/jira/browse/SOLR-7735">SOLR-7735</a> for more info.

+ <li>A bug was introduced in Solr 4.10 that caused index time document boosts to trigger excessive field
+boosts in multivalued fields -- the result being that some field norms might be excessively large.
+This bug has now been fixed, but users of document boosts are strongly encouraged to re-index.
+See <a href="http://issues.apache.org/jira/browse/SOLR-7335">SOLR-7335</a> for more details.
+<p/>
+</li>
+ <li>The Slice and Replica classes have been changed to use State enums instead of string constants
+to track the respective stats. Advanced users with client code manipulating these objects will

+ <li>Solr has internally been upgraded to use Jetty 9. See <a href="http://issues.apache.org/jira/browse/SOLR-4839">SOLR-4839</a> for full details, but there are
+a few key details all Solr users should know when upgrading:
+<ul class="bulleted-list">
+<li class="bulleted-list">
+It is no longer possible to run "java -jar start.jar" from inside the server directory.
+ The bin/solr script is the only supported way to run Solr. This is necessary to support
+ HTTP and HTTPS modules in Jetty which can be selectively enabled by the bin/solr scripts.
+ In case you have a pressing need to run solr the old way, you can run
+ "java -jar start.jar --module=http" to get the same behavior as before.

+<li class="bulleted-list">
+The way SSL support is configured has been changed. Before this release,
+ the SOLR_SSL_OPTS property configured in solr.in.sh (linux/mac) or solr.in.cmd (windows)
+ was used to enable/disable SSL but starting in 5.2.0, new properties named as
+ SOLR_SSL_KEY_STORE, SOLR_SSL_KEY_STORE_PASSWORD, SOLR_SSL_TRUST_STORE,
+ SOLR_SSL_TRUST_STORE_PASSWORD, SOLR_SSL_NEED_CLIENT_AUTH and SOLR_SSL_WANT_CLIENT_AUTH
+ have been introduced. The bin/solr scripts configure the SOLR_SSL_OPTS property
+ automatically based on the above new properties.
+</li>
+<p/>
+ You should *not* configure the SOLR_SSL_OPTS property directly inside solr.in.{sh,cmd}.
+<p/>
+<li class="bulleted-list">
+Support for SOLR_SSL_PORT property has been removed. Instead use the regular SOLR_PORT
+ property or specify the port while invoking the bin/solr script using the "-p" switch.
+</li>
+<p/>
+<li class="bulleted-list">
+Furthermore, it is now possible to configure the HTTP client with
+ different SSL properties than the ones used for Jetty using the same files.
+</li>
+<p/>
+<li class="bulleted-list">
+Please refer to the "Enabling SSL" section in the Solr Reference Guide for complete details.
+</li>
+</ul>
+<p/>
+</li>
+ <li>Support for pathPrefix has been completely removed from Solr. Since 5.0, Solr no longer officially
+supports being run as a webapp but allowed users to play around with the web.xml to have a path prefix.
+That would no longer be true. See <a href="http://issues.apache.org/jira/browse/SOLR-7500">SOLR-7500</a> for more info.
+<p/>
+</li>
+ <li>The package structure under org.apache.solr.client.solrj.io has been changed to support
+the Streaming Expression Language (<a href="http://issues.apache.org/jira/browse/SOLR-7377">SOLR-7377</a>). Any code written with the 5.1 Streaming API will have to
+be updated to reflect these changes.
+<p/>
+</li>
+ <li>Merge Policy's "noCFSRatio" is no longer set based on <useCompoundFile> element in the indexConfig section
+of solrconfig.xml. This means that Solr will start using Lucene's default for MP "noCFSRatio", with this
+new default Solr will decide if a segment should use cfs or not based on the size of the segment in relation
+the size of the complete index. For TieredMergePolicy for example (current default), segments will use cfs
+if they are less than 10% of the index, otherwise cfs is disabled. Old values for this setting
+(1.0 for useCompoundFile=true and 0.0 for useCompoundFile=false) as well as any other value can be set
+inside the <mergePolicy> element in solrconfig.xml. <useCompoundFile> will only apply to newly created
+segments. See <a href="http://issues.apache.org/jira/browse/SOLR-7463">SOLR-7463</a>.
