* Effective September 29, 2023, Azure Synapse will discontinue official support for Spark 2.4 Runtimes.
22
-
* Post September 29, we will not be addressing any support tickets related to Spark 2.4. There will be no release pipeline in place for bug or security fixes for Spark 2.4. Utilizing Spark 2.4 post the support cutoff date is undertaken at one's own risk. We strongly discourage its continued use due to potential security and functionality concerns.
23
-
* Recognizing that certain customers may need additional time to transition to a higher runtime version, we are temporarily extending the usage option for Spark 2.4, but we will not provide any official support for it.
24
-
***We strongly advise proactively upgrading workloads to a more recent version of the runtime (e.g., [Azure Synapse Runtime for Apache Spark 3.4 (GA)](./apache-spark-34-runtime.md)).**

* Announcements about the 2.4 deprecation were also added within the product. The lifecycle for Synapse Spark states that for deprecated runtimes, ["Spark Pool definitions and associated metadata will remain in the Synapse workspace for a defined period after the applicable End of Support date. However, all pipelines, jobs, and notebooks will no longer be able to execute”.](/azure/synapse-analytics/spark/runtime-for-apache-spark-lifecycle-and-supportability)
