The version here does not mean anything relevant to the support by the OS. BT4.0 in terms of hardware is compatible with bluez5 in terms of software. This is only the features supported by the hardware version. As the 5.0 specification is rather new, only in recent years there are BT5 adapters in the stores AFAIK.
