-2020xxxx               6.X.X
+20201012               6.3.2
        - Increase limit of READ/WRITE BUFFER command for improved compatibility
        SGI Iris hosts
+       - Add new config option to enable blind writes to improve SD card write
+       performance. This was previously enabled default but causes problems
+       with some SCSI hosts.
 
 20200419               6.3.1
        - Added checks to ensure the correct firmware version is loaded.
