- New support for 40LD firmware found in Series 475 and 471 adapters. - Better support for 8LD firmware adapters - Ioctl passthrough interface for userland utilities. - Improved error handling and queueing. - Several bugfixes (including the 'still open' shutdown bug and closing some small race conditions). - Zone-style command allocator, reducing memory wasted under heavy load conditions. - CAM interface (disabled and not fully working) for SCSI passthrough access to non-disk devices Thanks to AMI for supplying a pile of new adapters and various other help in making this happen.
