This is yet again an impressive list of good things. Always appreciated are "Remov*" features :)
I'm especially interested in ephemerons and how it improves the weak structures in the image. Hope the image support that makes use of the vm features follows soon. A wish would be to know a bit more about the permanent space news. Great work as always. Thanks!
