@marcchabrol can u or someone look at it?

Few more suggestions:

1. Please change eol to eoes and add eoasColumnLabel: Commercial Support so distinction becomes clear
2. Change eol to the EOL dates of the Development Edition accordingly. This should follow eol(X) = releaseDate(X+1) from what I understand.
3. A customColumn for the corresponding ubuntuVersion would be nice. You can check vmware-photon.md for a simple usage.
4. Should we add a Active Support column? I'm guessing only the latest major release gets new features (the next will be 8.1?). This will be helpful information as well.

Q: Is there a changelog published for the Commercial Edition? Maybe just version numbers? Would be nice to have a link so users can check if they are lagging behind.

In addition to the above 3, there should be a latest key for every release as latestColumn is visible. Our build is erroring out with the following:

I found only this => https://wiki.zentyal.org/wiki/Official_Zentyal_doc - it's a docs, but there are all versions listed. I think, commercial and development editions version numbers are the same.

I also added custom column for corresponding Ubuntu LTS version.

And now what?

The points 1, 2, 4 and Q from #5182 (review) are still open/unanswered from my point of view. After that @captn3m0 can review again.
