Has the LXQT edition been discontinued?

I’ve been using this neat little distribution on my backup partitions, but it’s not listed any more. Has it been discontinued?

There is updated 21.0.4 ISOs here: index - powered by h5ai v0.30.0 (https://larsjung.de/h5ai/) by @linux-aarhus but he was looking for more people to help him maintain it here: Volunteers needed
