Create Patch Against a Specific Revision

This type of patch contains changes between an old revision and the current content from the selected item within the working copy.

This option is useful if you want to obtain differences between an older revision and the current state of the working copy (for instance, to test how current changes apply to an older version).

The steps are as follows:

Go to menu Tools > Create patch.
This opens the Create patch wizard.
Select the Create patch against a specific revision option in the dialog box.
Press the Next button.
The second step of the wizard is opened:
The Create Patch Wizard - Step 2
Select the revision to create patch against.
You can select between the HEAD revision and a specific revision number. For the other revision option, you can press the History button to display a list of the item revisions.
Note: If the revision to create patch against is older than the revision to which the working copy item was updated, the patch will include changes that were made after the selected revision.
Optionally, if you want to configure the options for your patch, press the Next button.
This options page does not remember your selections when creating future patches. It will revert to the default values.

The Options wizard page is displayed.
Press the Create patch button.
The patch is created and stored in the path specified in the Output section of the Options page or in the default location.
