+> * **All Spark jobs running on Azure Synapse Runtime for Apache Spark 2.4 will be disabled as of July 23, 2024.**
 > * Effective September 29, 2023, Azure Synapse will discontinue official support for Spark 2.4 Runtimes. 
 > * 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.
 > * 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.
