Further details of changes are available in the change log available at: http://lucene.apache.org/solr/6_5_0/changes/Changes.html

Please note, this release cannot be built from source with
Java 8 update 121, use an earlier version instead! This is
caused by a bug introduced into the Javadocs tool shipped
with that update. The workaround was too late for this
Solr release. Of course, you can use the binary
artifacts.

Please report any feedback to the mailing lists (http://lucene.apache.org/solr/discussion.html)

Note: The Apache Software Foundation uses an extensive mirroring network for distributing releases. It is possible that the mirror you are using may not have replicated the release yet. If that is the case, please try another mirror. This also applies to Maven access.
