Here's a breakdown:
* Original Run: The anime aired from 1979 to 1980.
* Sequel: "Anne of Green Gables: The Sequel" aired from 1987 to 1988.
* "Anne of Green Gables: The Good Stars" (2009): This was a new, 39-episode anime series that was meant to be a continuation of the original story. However, it ended abruptly and hasn't been renewed since.
So, while there hasn't been any official announcement about the series being discontinued, it's been dormant for a long time.
