Direct3D 12 is already supported too, I just don’t know which version it started with.

P.S.: referring to the page “Warcraft III: Reforged” of PCGamingWiki and this (How do I get the game to run in DX12?), if you’re suffering from crashes, or FPS drops, or mouse lag, give Direct3D 12 mode a try(after entered Blizzard App, click the gear icon on the right side of “Play”, choose “Game Settings”, check “Additional command line arguments”, input “-graphicsapi Direct3D12” without quotes and click “Done”), perhaps it will relieves some, of course the actual effects depend on the individual.
