I know
Slovakia light has reduced object count - haystacks and various tiny village objects and fences are removed. They made 20-30% of the total object count.
Slovakia light (summer/winter) has borders like in 1938 or 1945, together with Slovak city names in the south. Slovakia full (summer/winter) represents 1944 period, when the south belonged to Hungary (which replaced city names with their versions) and the border is different as well. Light map has three fictional bases in nearby countries modeled, since it is more online oriented. 1944 map has only historical airbases.
It is all in 409 guide
but there is one mistake about Slovakia maps
- no 1944, online and no names versions, but summer and winter full and light. Readme got it correct.
