This is basically correct in that the fix appeared in firmware around then
(the internal log says 117, but possibly that was never released---I've
confined my search to the development side).

However, it's not that simple in that releases of earlier firmware branches
were still being made for some time.  Our ID numbers increase monotonically
so these would have later numbers.  I haven't done an exhaustive search;
mostly these releases had L2CAP + RFCOMM on chip for embedded applications,
so you wouldn't care about them.  I don't see any evidence of a later HCI
release based on the old code, offhand (but don't take this as gospel).

If you want to be quite sure not to pick up a build which didn't have the
fix for reset, you could restrict the change to BlueCore 2 and later chips
using the "bcget chipver" call.  The early branches without the fix
only ever ran on BlueCore 1: the fix was made in major release 12 and
BlueCore 2 first ran on major release 14.
