Please post release notes for the firmware updates that are not listed here. In other words one for BES_1028.cfw, one for HFP-CVC.dfw, one for BES_13-0506.cfw, one for HFP-A2DP-CVC.dfw.
Also, if there is an explanation why 10- firmware (10-1028) is newer than 12-xxx firmware I'd be interested in knowing.
