Do all versions of an arXiv paper appear in Google Scholar? I know that new arXiv papers usually appear in Google Scholar within a few days or weeks. My question is: if someone submits a replacement of his/her arXiv paper, does the new version of the paper also appear in Google Scholar?
Remember that the way the arxiv works, the default paper identifier goes to the most recent version that's been uploaded. So even if Google Scholar caches an older version, it's using the same URL. Now if you make changes like changing the title and/or material parts of the abstract, then it might take a while for the new title to percolate through the search indices.
