2 - Fix synchronous negotiation bugs
5 - Performance improvements to improve throughput at all scsi speeds
6 - Add new "turbo" speed option to boost speeds.
7 - May not be reliable, and use is not supported.
8 - Async timings trimmed
9 - Sync speeds boosted to theoretical 15.625MB/s, with 12.0MB/s measured
11 - SD card put in "high speed" mode.
12 - USB for configuration/firmware updates is disabled in turbo mode when
13 processing SCSI commands. A power cycle may be required to connect
14 via USB to reset the 48MHz clock back to 48MHz.
15 - Fix scsi2sd-util6 size and sector-size inputs
16 - Fix crash when configured scsi disk starting sector is less than
20 - Enable synchronous transfers on SCSI1 hosts
21 - Support 4MB/s sync transfers for Amiga A590 (WD33C93)
22 - Merge v4.7 release changes, excluding custom mode/inquiry pages
26 - Fixed SCSI timing issue
27 - Added glitch filter on SCSI signals.
28 - Re-implemented SCSI parity checking.
31 - Fixed write issue with UHS-I Speed Class 3 SD cards.
32 - More stability bug fixes
35 - Fixed "protocol error" issues when saving configuration to SD cards.
36 - Synchronous transfers supported ! 5MB/s and 10MB/s supported.
37 - Fix for accessing data via USB with more than 2 devices configured.
40 - Fix performance bugs
43 - More SCSI bug fixes (some timing issues resolved in the FPGA image)
44 - Firmware update support using scsi2sd-util6.
50 - Improved SD card compatibility
51 - Fixed SCSI interfaces on slower SCSI controllers
52 - Significant performance improvements
53 - Added SD card hotswap support.
56 - First BETA firmware for the 6.0 hardware version of the SCSI2SD.
