How to get version history from SharePoint

Thanks a lot for this - the sample file with some variations was very helpful.

Anonymous , WG_ELHT - I found a way to get the comments from the previous versions. WRT this Answer from SE, you can call a Versions method.

I was able to use that by cloning the VersionQuery function and mucking around a bit - have to change the API function called and get some different parameters, but I didn't have to touch the bottom half of the function.

I call that using a clone of the Documents query, then I used Merge Queries to blend that data with the Documents query in the sample file.

As noted in that Answer, a weird "feature" is that Versions doesn't return a row for the current version, only the history. You can dig a comments column out of the Versions.Properties data returned by the function described above, then muck around some more to get a tidy list.
