When adding files to a review, you can set the form of review taking place in the 'Add to Review as' drop-down menu:
- 'Whole Files' — Adds the entire file with all content, rather than just a diff with context.
- 'Diffs' — This is the default behaviour. This allows you to add multiple revisions of a file to one review and compare them in-review, in context with the change history.
- 'Diffs to Last Reviewed Version' — This adds files with a diff to the last reviewed changeset.
- 'Diffs to... (a particular revision)' — This allows you to specify the file to show the differences between two specific versions of a file.
- 'Diffs to Last Branch Point' — This adds files with a diff to the revision each file was last branched.
