why is it that a new version of page is created after publishing without changing page content

[belitex]

I clicked the 'Edit' button but did not change anything of a confluence page, then published it and found a new version in page history, which showed nothing diff when I compared with the last version.

I am wondering why confluence adds new version since there's no change. Does this affect performance of confluence?

Confluence doesn't try to be clever when you make a change, it just accepts what you've posted as new.

This isn't quite as useless as you think - the information that you might have been thinking of editing a page and got as far as clicking edit tells us that there is current interest in the page.

As for performance, no significant effect, it's just one more version.

Hi @belitex 

This is to show when last the page was published and who published it as well.

If you need to know who last modified a page(publishing without modification should be tracked), this is one of the few ways to find this out.

Thank you, Jimoh

I think you are right about tracking publish event even that without modification.
