This means from [[MultiCardReader]] perspective notable firmware changes where made at 1.10 and 1.50.
From hardware perspective this means there are only updates made for Sony GL819 equiped CECHA/CECHC/CECHE's.
Because of the lack of new versions, that is why 1.08 mostly is reported (if any) for all models supporting [[MultiCardReader]] on the [[More System Information]] screen on the @MCC line.
