The patch had been available for a year, but the public warning wasn’t issued until August. Of the 550 publicly exposed LND nodes identified, 71% were still running affected versions as of October 13, while only about 10% had upgraded by then. The denominator for this percentage is that group of identified exposed nodes, not the entire network; those versions accounted for about 6.4% of channel capacity at the time.

Distribution appears to have been the main source of delay: the largest waves of upgrades followed bundled platforms such as Umbrel, whose releases lagged LND by 19 to 41 days.
