Looks like since the release of GNOME 3.34.0 in September 2019 I made exactly 500 commits in GNOME Git. :)
My main focus was on updating documentation. The user help of cheese, gnome-klotski, gnome-mahjongg, gnome-nibbles, gnome-robots, gnome-terminal, gnome-tetravex, iagno, lightsoff, quadrapassel, rhythmbox, zenity should be up-to-date in 3.36 again.
(If not, then report issues in GNOME GitLab with the label “8. User Docs” or contribute patches yourself.)
This also included updating a majority of outdated screenshots (both English and localized versions when feasible) across projects.
I also took the liberty to push quite some trivial markup fixes in some translations when a language was not already reserved for translation on GNOME’s translation platform (as such actions would interfere).
