Radicale 3.0.3 is available. Please bump.
FYI: I am currently working on a bump from 2.1.11-r1 to 2.1.12 which is the
latest from the 2.x branch.
Ebuild 2.1.11-r1 is lacking GLEP 81 and other things.
Made PR for 3.0.6 and added support for Python3.9. More info here: https://github.com/gentoo/gentoo/pull/20143
