Patchdiff

PatchDiff saves a snapshot of your character's spell, talent and item tooltips every time you log in. When Blizzard changes a number or a text, PatchDiff shows you the difference in a clear in-game window: old and new line side by side, changed numbers highlighted, with the percentage change.

It also catches silent hotfixes that never appear in the patch notes.

Features
- Compares spells, class talents, trait trees and equipped or carried items
- Report window with filters, search and a history of earlier reports
- Login notification when something changed
- Note in spell and item tooltips: "changed on Oct 08 (-4.3%)"
- Flags uncertain changes that may come from your own level, gear or talents
- No bundled database, works in every client language

Commands
/patchdiff - open the window
/patchdiff test - add a demo report to preview the window
/patchdiff scan - compare now

The first login of each character only saves a baseline. Changes are reported from the next login on.
