Wonder if now that the B10A is discontinued there will be no more firmware development?
They seem to be pretty good at maintaining firmware. Perhaps active development/new features may stop, but they will certainly fix any bugs that come up.
p.s. your signature is technically wrong, there's no such thing as LLU fibre
LLU is local loop unbundling, where ISP's run their own hardware on the local loop (the copper part). For FTTC to be LLU would mean each ISP had their own fibre cabinet.
