I’ve been wondering if there is any online service which allows one to compile a document using different versions of TeX Live (2018, 2017, 2016, 2015, …) and compare the result. I’m imagining something like browsershots (web development) or, to a lesser extent, ideone (general programming) for TeX.

I often find myself wishing that something like this existed when comparing document output between different versions of TeX Live or finding out when a bug in a certain package was introduced/fixed. However, having so many different full installations of TeX Live side by side is not something that is easy to set up or maintain. So, is there another solution that allows comparing different versions of TeX Live quickly?

    I'm not sure why you say it's hard to have different TL versions set up: I have every one since TL'09 on my laptop. However, 'TeX Live version' is a rather imprecise thing to use for tracking package bugs: it's only engine binaries that are fixed. For individual packages, the version can change throughout the year. – Joseph Wright Dec 28 '18 at 8:09
  • @JosephWright It’s hard in the sense of requiring continuous manual maintenance, a lot of time for the initial setup and a lot of disk space. What I was thinking of were the “frozen” versions of TeX Live at the end of the year. – Socob Dec 30 '18 at 19:08
  • @Socob Well yes you need a bit of disk space, but the effort is pretty minimal once you get things set up – Joseph Wright Dec 30 '18 at 19:09
