Gunnar, Platform may also change their policy over time so you should not pick a schema that assumes Platform will forever work like today
I'm with Gunnar on this one. If the release structure/rhythm changes, we can always change the versioning again to better suit the new release structure. But not the other way around, we shouldn't change to a versioning scheme that doesn't suit the current release structure. Your suggestion of having a real date like "16.10" makes it totally unclear if it is a major release or a minor one.
