 == Solr 9.5
-=== Curator upgraded to 5.5.0 and requires Zookeeper 3.5.x or higher
+=== Dependency Upgrades
 <<#solr-8-2,Solr 8.2 recommended using Zookeeper 3.5.5>> and now with Curator 5.5.0 requires https://curator.apache.org/docs/breaking-changes/[Zookeeper 3.5.x or higher]. This primarily affects users of `hadoop-auth`, but usage of Curator could affect other parts of Solr.
 
 === Global Circuit Breakers
 * Circuit breakers can now be configured globally, not only per collection. See xref:deployment-guide:circuit-breakers.adoc[Configuring Circuit Breakers] for more information.
 
-=== Environment variables and syste properties
+=== Configuration and Ease-of-Use
 * Solr will now automatically resolve all environment variables with `SOLR_` prefix, and set the corresponding system property. This is useful for configuring more aspects of Solr through environment variables, such as for containers. Underscores are replaced with dots and strings are lowercased.

+* Collection and Replica Properties may now be used as property substitution variables in configuration files (e.g. solrconfig.xml).
