It’s available already in the testing release: [Testng Needed] Krita updates all the libraries it depends on
And it will be in the next release of Krita when it comes out. There’s no timeline set on a release date as far as I’m aware, but if you’re impatient, just use the test version linked above. It’s what would be in the next version of Krita if it were released today.
Edit: changed the link to Dmitry’s test instead of last night’s nightly, since that’s the current thing.
