Yep they changed it in the 2020 to 310.4(A) they did a lot of good work on 310 in the 2020 cleaning it up and making it more relevant for everyday installers and inspectors.
In the 2023 nec code book for the long time rating exray equipment, article 660 which is xray equipment, it didn't specify or say anything about long term rating, why? Because in the 2020 nec code book it did talk about king term rating.
