A very fast update, so far not much to write home about. Mint is offering their 5 year support Just open update manager then select EDIT and the update option is listed at the bottom of your drop down
When I have the time, I'll do a fresh install of Mint 20 on my main machine. I don't mind upgrading the other ones, but after playing so many games and installing so many applications, there is a lot of residual files that need to just go away.
