As far as I am aware, the last update to the firmware was to fix the bug that was discovered by Adrian Kennard of
A&A. That is the version from which Wolfy created the
_unlocked and the
_webgui images.
As for vectoring support, I haven't been following the details too closely. If the HG612 device responds to the following command --
xdslcmd info --vectoring -- then I would assume that it would be capable of operating on a circuit which has vectoring enabled.
