Blizzard has started using hotfixes more and more over the years and are now becoming a vital part of WoW's architecture.
As such, sites like MMO-Champion and Wowhead rely on the submissions of user data to fill their databases.
Support for hotfixes is added throughout WoW.tools as well, but to keep the data up to date I need a good amount of users regularly uploading hotfixes.
This is where you can help! I've put together an application that keeps an eye on WoW's hotfix file and uploads it after you close WoW. These files do not contain personal information or anything like that.
