* Atomic/partial updates to nested documents now _require_ the `\_root_` field
to clearly show the document isn't a root document. Solr 8 would fallback on
the `\_route_` param but no longer.
-* SolrJ: The project is migrating away from the Apache HttpClient dependency
in favor of Jetty's client (supporting HTTP/2), to occur over the 9x releases.
We deprecated HttpSolrClient and friends in favor of Http2SolrClient and
equivalents. For SolrCloud, the former CloudSolrClient was renamed
CloudLegacySolrClient (deprecated), and instead BaseCloudSolrClient was renamed
to CloudSolrClient and given a Builder for the Jetty based HTTP/2 client.

+=== Solr Binary Release `dist/` Directory
+
+The `dist/` directory in the Solr binary release has been removed as of Solr
9.0.
+
+* The `solr-core` and `solr-solrj` jars can be found under
`server/solr-webapp/webapp/WEB-INF/lib/`.
+* The Solr module jars can be found in `modules/<module-name>/lib`, packaged
individually for each module.
+* The `solrj-deps` (SolrJ Dependencies) are no longer separated out from the
other Server jars.
+Please refer to the SolrJ Maven artifact to see the exact dependencies you
need to include from `server/solr-webapp/webapp/WEB-INF/lib/` and
`server/lib/ext/` if you are loading in SolrJ manually.
+If you plan on using SolrJ as a JDBC driver, please refer to the
xref:query-guide:sql-query.adoc#generic-clients[JDBC documentation]
+
+== Major Changes in Earlier 8.x Versions
+
+The following is a list of major changes released between Solr 8.1 and 8.11.
+
+Please be sure to review this list so you understand what may have changed
between the version of Solr you are currently running and Solr 9.0.
+
+=== Solr 8.11
Review comment:
It makes kind of sense, since the target audience for 9.0 would
typically be someone upgrading from 8.x. And if you are on e.g. 8.4, you need
to catch up on the diff between 8.4 - 8.11.
Could be that improvements can be made here, but let's not rush anything.
I'd also check with Cassandra who I'm sure will have thougths on the subject as
technical writer.
