# 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Over time, certain Elastic functionality becomes outdated and is replaced or removed.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.

## 9.2.4

<dropdown title="Deprecation of partitioner settings in the Kafka Integration">
  The `partitioner` configuration options `default` and `uniform_sticky` have been deprecated in the Kafka output. [#206](https://github.com/logstash-plugins/logstash-integration-kafka/pull/206)These options will work correctly for the Kafka plugin version bundled with Logstash 9.2.x, but will be removed in a future release.The deprecations in the Kafka output were made to align with changes in the Kafka Client.
  At version 4.x, the Kafka Client removes the `DefaultPartitioner` and `UniformStickyPartitioner` partitioner implementations.
  It adds an improved [uniform sticky partitioner](https://cwiki.apache.org/confluence/display/KAFKA/KIP-794%3A+Strictly+Uniform+Sticky+Partitioner), which is the default.
