Median Blur in Blender

Hello Guys !
I don’t really know if it’s the right place but here I go :
I was looking for a median blur in the compositor but there isn’t any. I’ve search online and it seems that there is a patch for a median blur : T18417 . It says that it’s Closed and Resolved but I can’t find it in Blender. Is it because it’s under another name or it just not in the master branch ?
thanks for reading !
