Clean install of 01.21, the Nvidia live option is not usable on my Intel/Nvidia 950 system, but that's been the case this cycle. No surprise. Rather go with nouveau with Wayland at this point anyway. If I add the Nvidia drivers post-install I cannot use Wayland.
Added the [build] repo, updated.
Noticed it takes 15 seconds for the panel to appear after login. Croeso comes up right away, however. Pop-up details when hovering above items in the panel are much better with no weird artifacts on the screen. this was an annoyance on the normal releases before, likely just an Nvidia/X11 driver problem. Works well on Wayland.
LibreOffice and Firefox are looking good, launches faster than before. So far, so good. Excited to see the final product.
