• If you're upgrading XWiki you have to delete the 'solr' folder from the configured permanent directory of your XWiki instance in order for the Solr search to work. We upgraded Apache Solr in this release and this brought changes to the Solr schema and configuration files, which are cached in the 'solr' folder. Unfortunately we don't have support for automatic Solr search index migration at this point. The Solr index will be deleted as a result but it will be recreated automatically and the entire wiki will be re-indexed after a server restart.
