|Patch policy / How does patch assessment work?|
If a vendor releases a patch that replaces an earlier patch, the new patch is called a superseding patch. The patch it replaces is referred to as the superseded patch.
Sophos recommends you install the superseding patch to keep your computers up-to-date.
Example: If you search for virusX and see that the fix for the virus is available in patch P01, which is superseded by patch P02, Sophos recommends you install P02.
