Have the details been published anywhere? I looked briefly and only see stuff describing it in general and saying it is yet to be released.

These changes were a part of the 2024 edition of the Player's Handbook (PHB) and Dungeon Master's Guide (DMG), both now published, with more of it to come in other updated books. (Or "5.2E" if you prefer the simple decimal point of the 2024 updated Systems Reference Document [SRD] over "5E (2024)".)
