According to the MNSoft update site "NEW MAP & SOFTWARE UPDATE V15.0 WILL BE AVAILABLE IN MID APRIL 2021". We shall see. Hopefully software update will be something good.
I just checked the site a couple days ago hoping for something and it only had the November update and a UVO update that doesn't apply to the Stinger. Like you said, hopefully something good to bring it up to date with the 2022s
