+<h1>Apache Solr Release Notes</h1>

+
+<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>

+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13248">SOLR-13248</a>: The default replica placement strategy used in Solr has been reverted to the 'legacy' policy used by Solr
+7.4 and previous versions. This is due to multiple bugs in the autoscaling based replica placement strategy that was
+made default in Solr 7.5 which causes multiple replicas of the same shard to be placed on the same node in addition
+to the maxShardsPerNode and createNodeSet parameters being ignored. Although the default has changed, autoscaling
+will continue to be used if a cluster policy or preference is specified or a collection level policy is in use.
+The default replica placement strategy can be changed to use autoscaling again by setting a cluster property:
+curl -X POST -H 'Content-type:application/json' --data-binary '
+{
+ "set-obj-property": {
+ "defaults" : {
+ "cluster": {

+ <li><a href="http://issues.apache.org/jira/browse/SOLR-13248">SOLR-13248</a>: Autoscaling based replica placement is broken out of the box. Solr 7.5 enabled autoscaling based replica
+placement by default but in the absence of default cluster policies, autoscaling can place more than 1 replica of the
+same shard on the same node. Also, the maxShardsPerNode and createNodeSet was not respected. Due to these reasons,
+this issue reverts the default replica placement policy to the 'legacy' assignment policy that was the default until
+Solr 7.4.

+in the response header.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12827">SOLR-12827</a>: The cluster wide defaults structure has changed from {collectionDefaults: {nrtReplicas : 2}} to
+{defaults : {collection : {nrtReplicas : 2}}}. The old format continues to be supported and can be read from
+ZK as well as written using the V2 set-obj-property syntax but it is deprecated and will be removed in Solr 9.
+We recommend that users change their API calls to use the new format going forward.
+<p/>
+</li>
+ <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.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-12861">SOLR-12861</a>: Added a Solr factory for ByteBuffersDirectory, which will replace deprecated RAMDirectory in Solr 9.0.
