Solaris is still a thing, even though it’s now developed by a company nobody likes and seems to have lost all of the momentum among enthusiasts, so much so that I doubt anyone will even really care about this news item. Oracle released Solaris 11.4 almost three years ago, and is still updating it with monthly updates. Solaris 11.4 SRU30 is the latest one, released on 16 February.
The update consists mainly of updates from upstream packages, but there seems to be little in the way of new features or big improvements. For those, we have to most likely wait until Solaris 11.5 or 12.0, if Oracle ever makes it that far with the formerly open source operating system that they closed back up.
