-=== 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

=== Global Circuit Breakers
* Circuit breakers can now be configured globally, not only per collection.

-=== Environment variables and syste properties
+=== Configuration and Ease-of-Use

prefix, and set the corresponding system property. This is useful for

including improved tracking of distributed collection commands and increased
coverage for internal requests made with the Apache and Jetty HTTP clients.
