Nice milestone: @notion 4 is now available in Debian unstable, and no longer needs to be in the non-free section!
Thanks to Dima Kogan for doing the bulk of the work here.

@notion this congratulations, is a glad news if a non-free now became free software.
"- Notably, Notion is now LGPL again, so can be moved back
from non-free into the general distribution"
