Confusion about LTS versions. Any comprehensive documentation regarding everything LTS?

[Batanun B]

Hi,

Is there any documentation focused on the LTS versions of Varnish Cache? And with that I mean things like "What does the LTS version of Varnish mean?", "Why should or shouldn't I choose an LTS version?", "What is the latest LTS version?" and "How do I install an LTS version?".

Currently I can't find any such documentation anywhere.

We use Varnish Cache 6.0 LTS (6.0.6) now, on Ubuntu 18.04 LTS. I'm testing setting up a new Varnish server, on Ubuntu 20.04 LTS, and it automatically installs Varnish 6.2.1-2.

Is that an LTS version? How can I verify that? And if not, how can I make sure that the version being selected is an LTS version?

I followed the instructions at https://packagecloud.io/varnishcache/varnish60lts/install#manual-deb and in the file varnishcache_varnish60lts.list I made sure to change "trusty" to "focal" to match the Ubuntu version.

Also, the "Releases & Downloads" page is quite confusing. First, it doesn't say _anything_ about LTS versions. Secondly, it specifically mentions version 7.0.2, 6.6.2 and 6.0.10 as supported, and says "All releases not mentioned above are End-Of-Life and unsupported". What does that mean?

https://varnish-cache.org/releases/

Also, is there a place where we can see the roadmap for future planned LTS versions? Now I have no idea if there will be a new LTS coming next week, next year, or 2030.
