Alternator
- describe_multi_item previously misinterpreted its last argument, causing a double conversion that undercounted RCU. The fix removes the extra conversion and updates the API. Tests pass against DynamoDB, ensuring correct RCU calculation #25847
Performance
- The setup tool now checks if 4k block sizes are preferred by the disk, even if it advertises 512 byte physical sector sizes, to compensate for disks that misreport the physical sector size. #25315, #25441
Log and trace
- Incorrect order of parameters in repair log #26536
