The latest version of CMS UI requires at least version 4.1.1 of Microsoft.OWIN.Host.SystemWeb. However, EPiServer.Commerce.Security only supports version 3 of that dependency. So if you have Commerce installed, and try to update to the latest version of CMS you will get the following error:

The latest EPiServer.CMS (11.20.4) depends on Microsoft.OWIN.Host.SystemWeb >= 4.1.1; via EPiServer.CMS.UI.AspNetIdentity 11.32.1. However the latest EPiServer.Commerce.Security (13.29.0) depends on Microsoft.OWIN.Host.SystemWeb < 4.0.0

This fix updates the EPiServer.Commerce.Security's dependency to Microsoft.Owin.Host.SystemWeb to be [4,5).

3. Set both discounts to exclude each other. 

Expected result is that a customer can get both discounts. 
Actual result is that only the discount with highest priority is applied. 

This fixes a scrollbar issue where the list of items disappear when adding a Line item to a cart in the Order Management (CSR) user interface.
