Please bump G'MIC to 2.0.3. Should probably depend on GIMP-2.9.6. Reproducible: Always
gmic 2.0.4 was released a few days ago: https://discuss.pixls.us/t/release-of-gmic-2-0-4/4902 It would be nice to see the gmic version updated in the tree.
gmic stable branch reached v2.1.0: https://discuss.pixls.us/t/release-of-gmic-2-1-0/5256
