HOTFIX 2016.1, 2016.2, 2016.3, 2016.4 - Currency values now show up to 4 digits of precision on Order list and edit pages

Currency values on the Orders List and Order Edit pages in the admin now show up to 4 digits of precision if values exist in those places. This is to address an issue where the balance would appear to be $0.00 but would still show up as red indicating it wasn't balanced due to the remaining fractions of a cent.
