"Near fresh" here means "reasonably new", nowadays, "same year" or "1 year old"... Maybe "2 years old" also reasonable.
I used apt install pandoc today at UBUNTU 16 LTS, and for my surprise it is not a "fresh version", a very old version was installed: pandoc --version is 1.16.0.2 (of 2015!!) instead a 2019 version, v2.9. Out of curiosity I did the same on other machine with UBUNTU 18 LTS, same ugly surprise.
How to install stable "recent Pandoc", and not a 5 years-old version?
Or how to upgrade it by "plug and play mode"?
PS: internet/google show nothing, only very confuse comments. Install page also very confuse. No "clean and objective" install instruction for apt neither upgrade... Only other topic, "cabal update".
