How many "seasons" of Lupin the Third are there?

I’ve been a fan for years now, but I never quite understood exactly how many “seasons” there are. Even the wiki seems to have some missing things. I’m also confused about if there’s currently a new season on right now. I remember a couple years ago (Like 2010 or 2011) commercials and pics for a new season, and the animation was bright and modern. Now I hear about this series that started earlier this year called “The Woman Called Fujiko Mine,” yet that’s not the one from the commercials I saw. The wiki doesn’t seem to refer to what I saw anywhere.
