For brokers, fixes address log cleaner issues, ISR thrashing, tombstone removal, offset retention calculation, replica fetcher thread errors, and NullPointerExceptions. For Kafka Streams, improvements cover user configuration handling, topic not found errors, resetter performance, cache eviction, and KTableSource simplification.
