This means from Bluetooth perspective notable firmware changes where made at 1.10, 2.70, 3.00, 3.10, 3.20, 3.30 and 4.20. From hardware perspective this means there are only updates made for Marvell 88W8780-BIE2 equiped CECHL/CECHM/CECHP/CECHQ's and one (the 1.10-2.60 one) for previous (Marvell 88W8580) SKU Models. However, so far only '0E18' has been reported for all models on the More System Information screen on the @BT line.
