Is Feature 4.1.0 in recalbox-rpi4_64_JammaDoard.img.xz build?

[Thirdeyedynamo]

Greetings all!
I am trying to add sounds to my Donkey Kong that plays but has no sound and one of the posts on this forum said to wait for Recalbox feature 4.1.0. Does the Feature 4.1.0 appear to be in the "recalbox-rpi4_64_JammaDoard.img.xz" build? Am i completely off base with this question...
Please advise
Thank you in advance for your responses!
