Futurama season numbering is messy and inconsistent. In some places the movies are counted. In some places, the aired ordering of episodes is used. In other places the dvd release order is used. I think there's some seasons that were aired in 2 separate parts, so in some cases those are considered 2 seasons, or 2 half seasons, or 1 season.

Since both Plex and Sonarr use thetvdb, I tend to use that as the source of truth as well. And according to that site, s8e10 doesn't air until end of September.

Season 8 is the season that just started last week. There's a second episode coming out today if it isn't already.

Some sources will say there's 11 seasons because they split up some older ones for some reason but officially there is 8.

Season 8 on more torrents is probably considered to be the new hulu reboot. This is due to the disparity in the home release seasons and the television TV seasons. So most likely if you have seasons 1-7, you have all the home release versions of the show, and therefore have the entire library.

Thank you everyone for the insightful information ! I appreciate you all !

Seasons 6 and 7 were split into two halves for airing. This led to some sources claiming that each half was a separate series.

The same problem happened with the first four seasons (the OG ones). They were split up and episodes were aired out of order, so some sources claim that there are five seasons. It's really, really annoying if you want to watch the episodes in order and Plex has decided that "fuck you no, there are five seasons of random lengths" >_<

Incompetent publishers messed the seasons up

Season 8 and Season 11 are the same thing. You didn't miss seasons 8-10.
