* A gateware-level input edge counter has been added, which offers higher
throughput and increased flexibility over the usual TTL input PHYs where
edge timestamps are not required. See :mod:`artiq.coredevice.edge_counter` for
the core device driver and :mod:`artiq.gateware.rtio.phy.edge_counter`/
:meth:`artiq.gateware.eem.DIO.add_std` for the gateware components.
