How does a workspace file differ from a request file?

A workspace file is always the latest version of the output file created by a job run via the Jobs site.

A request file is the version of the output file at the time that it was added to a release request.

When a file is added to a release request, a copy is taken of the current contents of that file. This is deliberate, and ensures that a file added to a request does not change during the review process.

If a subsequent job is run within that workspace which changes the file, the workspace view will show the new file contents and the release request view will continue to show the old file contents from the time that it was added to the request. Authors can choose to update the file on the release request, but this does not happen automatically.

After a file has been updated on a release request, it must be reviewed again by two output checkers, even if the previous version of the file was already approved.
