Marketing people should be let anywhere near the software versions!
Windows: 2000, XP, Vista, 7, 8, 8.1, 10
Unity: 5.6, 2017.1, ..., 2022.3, 6.0
iOS: 18, 26
Now one guy at Unity (me) has to change iOS min version check to also include check for non-existent 19-25 range. Hopefully it is not me in the future who'll have to deal with those skipped version somehow coming to existence.
