A stable app-portage/gemato-14.3 with python3_8 in PYTHON_COMPAT is needed in order to stabilize sys-apps/portage-2.3.79 with python3_8 in PYTHON_COMPAT.
As long as python_targets_python3_8 is in use.stable.mask, we can stabilize sys-apps/portage-2.3.79 without stabilizing gemato-14.3.
That's what I wanted to say. However, this version is ready to be stabilized anyway, so let's do it.
x86 stable
arm64 stable
Stable for alpha/amd64/arm/hppa/ia64/m68k/ppc64/ppc/s390/sh/sparc (ALLARCHES policy).
