Some of the Japanese translators who are contribuinge to kicad-i18n
(https://gitlab.com/kicad/code/kicad-i18n) are

Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
We don't use e-mail addresses for contributors in the about box these
days. The field is re-purposed as an optional additional field to allow
for disambiguation of contributors, should they request it.
Don't use the same "post_*" icon in the treeview. The badge gives an
action that doesn't apply in the treeview.
Also renames different file blobs to the "file_*" prefix.
Flags != language See http://www.flagsarenotlanguages.com We now use
local, untranslated language names for all languages.
Languages that have not been updated in >5 years and have less than 15%
of available strings translated have been removed from the menu options.
If a translator steps up to update the .po files, we can re-add them
Removes the TTL triangulator in favor of the delaunator triangulator.
This removes the only AGPL code in the KiCad codebase and therefore
allows the full project to be licensed under the GPLv3.
Previously, the build version would only update if the dialog_about.cpp
file were modified. This moves the date generation into the same file
as the build version, so it will be updated whenever a new version
is made.
