The concept of Country as a degree of freedom has been expanded to Location: the system now comes with ISO country codes as well as IATA City codes. You can also use any codes that you would prefer. All references to Country have been changed to Location (I hope).
The Leave Tracking title at the top of the left navigation frame is now a Link Hotspot for users with the [View Allowances] role. This link takes you to a Leave Summary Views navigation frame which has more privledged options (like Locations). You will need to use the Leave Summary Views frame for your Setup activities. Clicking the Leave Summary Views title takes you back to the original Leave Tracking default frame.
