List File Versions

List the versions of a file, newest first by default. Each write that changes the bytes records one; identical rewrites do not. Collaborative edits, and repeated workflow writes by one author, fold into a version under ten minutes old and written in the last five. Renames and moves are not versions. Retention removes older versions by age and plan but keeps the newest ten, so numbers can have gaps.

OAuth scope: api:read.
