focus pixels can be removed in mlvapp if you use chroma smooth in raw corrections if focus pixels removal options in mlvapp wont work.For me sometimes they wont and i have to use chroma smooth, nothing to be worried about but good to know, if it works it works.
I dont believe there was build without focus pixels, sometimes they just arent visible that well depending on what you shoot and they appear again with the same build and settings if you shoot something else.
