I wish to compare the last published version of a Knowledge article with the corresponding unreleased draft, as these are often very long and hence it is very difficult to spot what the change was in the new version before sending them to approval.
So far I have found almost nothing about this feature except this idea that somewhat resembles my requirement but we can not wait till that development is completed.
I have found this article too however what we need is a left and right view pane (like eclipse etc) with insertion deletion etc to compare between 2 versions of document.
I have not found any relevant App in Appexchange too.
Any pointers on how to proceed will be helpful, thanks.
