LibreOffice Online pot files were finally updated in Pootle. If you have
little time, please ignore help file, because it has not changed since May,
2016, and I have no idea why the half of it became fuzzy after the update.
Also, in UI you can ignore the endless list of Unicode ranges, which is
from the Insert Special Character dialog. If we don't take these two things
into account, then the update is minimal. Of course, if you have time, feel
free to click through the fuzzies.
