# Logstash deprecations
Over time, certain Elastic functionality becomes outdated and is replaced or removed. To help with the transition, Elastic deprecates functionality for a period before removal, giving you time to update your applications.
Review the deprecated functionality for Logstash.
While deprecations have no immediate impact, we strongly encourage you update your implementation after you upgrade.

## 9.1.10

<dropdown title="Deprecation of settings in the Kafka Integration">
  - An upcoming release of the Kafka Integration plugin will update the Kafka Client version to `4.x`. This version of
    Kafka Client removes the `DefaultPartitioner` and `UniformStickyPartitioner` partitioner implementations, and
    includes a new default partitioner which is an
    [improved](https://cwiki.apache.org/confluence/display/KAFKA/KIP-794%3A+Strictly+Uniform+Sticky+Partitioner)
    uniform sticky partitioner.
  - For this reason, the `default` and `uniform_sticky` options for the `partitioner` configuration option for
    the Kafka Output have been deprecated. While these options will work correctly for this version of the plugin, they
    be removed in a future version of this plugin.
  - For more information, check [PR 206](https://github.com/logstash-plugins/logstash-integration-kafka/pull/206).
