I installed 15.4 alpha with an Xfce desktop in a VirtualBox VM using the default disk partitioning and repos. Some random thoughts: 1. I liked the display of what was happening in the main screen while booting the installation .iso. That may not be new, but I do not remember seeing it with earlier versions. 2. The initial estimated time to install did not seem to be as pessimistic as before. I remember 2 hour estimates in the past - this one started well under an hour. 3. As installation neared completion, the estimated time became over optimistic as before, but that is not a problem. 4. My testing is minimal, but I was able to install git and the kernel development packages and from there, I cloned an out-of-kernel wifi driver, and built it without any problems. It is a PCI device, thus no chance to test it, but the build went smoothly. 5. I appreciate the 5.14 kernel. Having 5.3 kernels in the latest Leap version has been somewhat of an embarrassment. As I use Tumbleweed for normal work, that was not a problem for me, but it was hard to recommend Leap to the users of other Linux distros. Larry
