2021.

People have certainly been asking for it for at least the last decade. Jail breaking doesn't count.

I bought a Kindle Paperwhite in 2020, it's been doing that since day 1 of my purchase without jailbreaking or anything.

It's not a new thing that journalists cover old features as if they've just been added, because they just found out about it and feel they're newsworthy

It's definitely not "a decade". I have the 2013 Kindle Paper white and it doesn't have that feature without JB, the oldest device supported is Kindle Paperwhite 7th Gen which is released in 2019.

It's likely you are just lucky to buy a KPW with that feature just rolled out.
