The most recent video in that playlist was uploaded in December 2020 https://www.youtube.com/watch?v=MkKgdq57uOo&list=PLZioPDnFPN... (before that the previous video was from October 2018; maybe you meant ~3 years ago)

There is also an 'antikythera fragments' playlist with the most recent video from September 2021 https://www.youtube.com/watch?v=BLBDKmFG90U&list=PLZioPDnFPN...
