I installed 12.5. Thank you so much for the 5 extra desktops and the other changes of course.
It isn't the so called end of life for the N900 by Nokia. You can better speak of a rebirth, thanks to the great job of the CSSU team.

Some feedback:
Background and theme is only working for the first four desktops, but I think you know it yourself as well.
Live wallpaper is working well on those 5 extra desktops.

The rate of updates is very good.
