6.0 and Warlords of Draenor
The addon is updated for 6.0 but the Disease Strength feature has been removed. In 6.0+ Death Knight diseases will no longer snapshot their strength. They update dynamically so there is no need to track their strength.
The Soul Reaper vs. Howling Blast functionality is also not needed now but it is still in the addon. You can disable it as Soul Reaper will always do more damage than Howling Blast. It will just show the Soul Reaper icon when appropriate.
Overview
DK Diseases will track your diseases on your target or focus.
You can choose either the block or bar display. It is highly configurable so check the settings to adjust the display to your preference.
