https://docs.tizen.org/platform/developing/installing/ says Tizen SCM tools support the following Linux distribution versions: Ubuntu 16.04/14.04/12.04, etc…

Given Ubuntu is at 21.04, does Tizen support any version above 16.04?

I get a little frustrated in general that a lot of Tizen documentation seems old and abandoned.  One page says the latest release is 5.5 even though its 6.5. Some of GBS tool setup references old releases. This makes you have to hunt around for and reconcile new and old information on a lot of platform development topics, since a lot of pages aren’t kept up-to-date.  Can Tizen start paying more attention to keeping its websites up-to-date with each release?
