With the PR, the star is visible. Does it look OK?

1. the id of the article has not changed - looks like you are comparing more than should be compared
2. as above it should be just comparing the value between old and new
3. should be showing the tag name and not the tag id. Also the old version had one tag and the second version had an extra tag. Doesnt look correct in this table.
4. Related to above. dont know why it says the old value was undefined. It didnt exist so should be empty
5. Should be language string not the component name

Dont know what "Saved on" is meant to mean here.

Found the string. There is supposed to be something after saved on

Video of more tests. Shows more examples of the issues reported above

#46073 (comment)
1 & 2 should be fixed
3 & 4as I said we don't know what we are showing. It can be a tag or it can be something different just having the same name. Guessing and then making DB queries to get some data that might be the right one will not end well.
5 Same here, we don't know. I can use Text::_() for it, not sure if it makes so much sense.

#46073 (comment)
I deleted too much lines, its fixed

tags

see video.

1. It should not say undefined when there are no tags
2. Just having the tag id isnt very useful

I can remove the undefined that's not a problem. Question of taste.

Tags is a problem that I don't see how we solve that properly. I could try to find names for the id, but we are in a situation where the meaning/existens of a tag can change.

How is that different to anything else eg category where the ID can stay the same and the Text/Name can change. We always show the Text/Name at the time of the comparison not at the time it was created - dont we?

We do, but does it makes sense when we compare something that was created two years ago with category/tag id=2 what was at the time "blue underware" and now it is "yellow cap"?

thats a valid comment and I would agree with you if that is what we did everywhere. But we dont. For categories and other things we show the current text and not the id number. I am just looking for consistency

@brianteeman I am still more on the site "not worth" but I added the ability to lookup a field when it is an array like tags. To make it work it needs a change in the #__content_types table.

{"sourceColumn":"tags","targetTable":"#__tags","targetColumn":"id","displayColumn":"title"}

must be added to the content_history_options column.

For convenience here is the value for article:

{"formFile":"administrator\/components\/com_content\/forms\/article.xml", "hideFields":["asset_id","checked_out","checked_out_time","version"],"ignoreChanges":["modified_by", "modified", "checked_out", "checked_out_time", "version", "hits", "ordering"],"convertToInt":["publish_up", "publish_down", "featured", "ordering"],"displayLookup":[{"sourceColumn":"catid","targetTable":"#__categories","targetColumn":"id","displayColumn":"title"},{"sourceColumn":"created_by","targetTable":"#__users","targetColumn":"id","displayColumn":"name"},{"sourceColumn":"access","targetTable":"#__viewlevels","targetColumn":"id","displayColumn":"title"},{"sourceColumn":"modified_by","targetTable":"#__users","targetColumn":"id","displayColumn":"name"},{"sourceColumn":"tags","targetTable":"#__tags","targetColumn":"id","displayColumn":"title"} ]}

I have tested this item ✅ successfully on 7c18733

I have tested this successfully. Thanks @rdeutz!

As discussed in the PR Testing Group while testing this PR, if you create a tag on the fly, there is no trace in the Preview under Versions until after the 2nd save.

When you add images then the information is duplicated

the image duplication is fixed now

When I do a preview in Joomla 6 the intro and full text are at the very bottom
When I do a preview in Joomla 5 they are at the top

Thank you @rdeutz for all the work you have done on this. There are still a few rough edges which the testers, especially @brianteeman, have highlighted and need to be addressed before it's bulletproof, but there is a lot that has improved, and it's so much closer to the finish line. Thank you to all the testers and also @bembelimen and especially @LadySolveig who have put a lot of time into helping solve issues and nudging it along.
