Andrew, thanks so much for keeping up on new releases (including HV which I have already downloaded). When I boot ubuntu 16 to create the 10/31 release, I will take time to test libaom update and hopefully check that in in November. I do not plan on upgrading for the dot release of ffmpeg -- that is 4.4.1 -- not worth the hassle. OK?
