Mainboard D2156:
Current version: D2156-S21 GS3
Upcoming version: D2156-S21 GS4

• The dual USB connector used for D2156-S21 has reached its EOL. In order to keep exactly the same USB connector available for D2156-S21 and to avoid any mismatch with the successor its part number had to be changed from B478-V7 to B478-V8. This affects the revision number of D2156-S21, but does not mean any hardware change.
• The chipset heatsink (Northbridge) has been modified (minor change incl. additional insulating foil) in order to minimize a possible risk of electrical short. This change has no influence on thermal behaviour.
• D2156-S21 GS4 is fully functional and mechanical compatible to D2156-S21 GS3.
