 - The performance of ingesting SQS data with the S3 input has improved by up to 60x for queues with many small events. `max_number_of_messages` config for SQS mode is now ignored, as the new design no longer needs a manual cap on messages. Instead, use `number_of_workers` to scale ingestion rate in both S3 and SQS modes. The increased efficiency may increase network bandwidth consumption, which can be throttled by lowering `number_of_workers`. It may also increase number of events stored in memory, which can be throttled by lowering the configured size of the internal queue. {pull}40699[40699]
 
 - Add kafka compression support for ZSTD.
