Select the starting and ending revisions in the From and
To sections.
You can select between the HEAD revision and a specific

The patch will only include changes between the two specified revisions, starting
with the changes that were made after the older revision.

If you want to reverse changes done between two revisions by using a patch file, you
can specify the newer revision in the From section and the older
version in the To section.
