See the https://wiki.apache.org/solr/ReleaseNote77[7.7 Release Notes] for an overview of the main new features in Solr 7.7.
When upgrading to Solr 7.7.x, users should be aware of the following major changes from v7.6:
*Admin UI*
* The Admin UI now presents a login screen for any users with authentication enabled on their cluster. Clusters with <<basic-authentication-plugin.adoc#basic-authentication-plugin,Basic Authentication>> will prompt users to enter a username and password. On clusters configured to use <<kerberos-authentication-plugin.adoc#kerberos-authentication-plugin,Kerberos Authentication>>, 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 <<distributed-requests.adoc#configuring-the-shardhandlerfactory,Distributed Request>> documentation.
