Unity 2019.2.11 was released yesterday, 24 hours later it's still not in the Hub and it hasn't been announced on the forums either. Last announcement was about 2019.210: https://forum.unity.com/threads/unity-tech-release-announcements.532033/page-2#post-5102999 So, it seems that we'll have to ask for it to be added to the Hub each time a new version of Unity is released? What about Unity 2020.1 Alpha 10? Has it been released too? Alpha versions not been announced and not having their own page, how could I know?
