What is the latest version of sketchup for desktop that is free?

Hi, I’ve been using sketchup make for a long time but for me it’s not a daily thing or even monthly. I just use it when I feel the need to be creative. I noticed a message that said sketchup in getting old (being the 2017 version) so is there a desktop version I can use that’s more up to date? If not it’s not a big worry as I enjoy using the version I have but if an updated version for free is up for grabs then I’ll happily take it.

You have the last free desktop version.
