illumos split from Solaris around the time Solaris 11 has been released. Since then the development of both mostly diverge. Unlike others I think that Solaris is still being developed but not so obviously. Partly because it is limited to paying customers (non-paying customers can only access official releases like 11.1, 11.2, 11.3 and so on. And this happens seldomly) and most changes happen in not so obvious parts (eg. low level tools and protocols). BTW: From its Solaris inheritance illumos got a lot of technologies despite the always mentioned SMF, ZFS, Crossbow and DTrace. Eg. authorizations, privileges and roles. Things that I miss when I look at other OS's. Many valuable things are hidden below the surface. Between Linux and illumos there is a big difference between their development philosophies. For me Linux takes now the part of Windows two decades ago: It is heading towards a monoculture with masses of lemmings running with it mostly ignoring superior technology around.
