In addition to these bug fixes, 8.6.3 users may notice that their Solr logs start with an "XmlConfiguration Ignored arg" warning produced by Jetty.  This message is caused by an underlying Jetty issue but can be safely ignored as Jetty configuration is still correctly processed.

Further details of changes are available in the change log available at:https://lucene.apache.org/solr/8_6_3/changes/Changes.html

Solr 8.6.3 also includes bugfixes in the corresponding Apache Lucene release:
