For people in computer science, a particular paper on arxiv may be updated frequently (even on a daily basis), and it is important to keep the version of arxiv up to date. I've looked up some previous discussions on this topic and learned that the hard part is how to resolve conflicts between versions.

So is it possible to add features, for example, an update of the original pdf when no other changes have been made? Or keep multiple different versions of the same paper (this can be judged comprehensively based on multiple aspects such as title, author, doi, etc.), but appear in the same entry?
