Clusters with <> will prompt users to enter a username and password. On clusters configured to use <>, users will be directed to configure their browser to provide an appropriate Kerberos ticket. ++ +The login screen's purpose is cosmetic only - Admin UI-triggered Solr requests were subject to authentication prior to 7.7 and still are today. The login screen changes only the user experience of providing this authentication. + +*Distributed Requests* + +* The `shards` parameter, used to manually select the shards and replicas that receive distributed requests, now checks nodes against a whitelist of acceptable values for security reasons. ++ +In SolrCloud mode this whitelist is automatically configured to contain all live nodes. In standalone mode the whitelist is empty by default. Upgrading users who use the `shards` parameter in standalone mode can correct this value by setting the `shardsWhitelist` property in any `shardHandler` configurations in their `solrconfig.xml` file. ++ +For more information, see the <> documentation. + === Solr 7.6 See the https://wiki.apache.org/solr/ReleaseNote76[7.6 Release Notes] for an overview of the main new features in Solr 7.6.
