Credit goes to Cyber_Kun's changelog thread for the inspiration.
While there are still some features that I plan on adding, this build should be pretty stable and allow players to quickly search for patches, hero changes and item changes. Have fun with it and if you find spelling errors, please PM me where you found them.
Clicking on the hero or item icons enters them into the search bar and double clicking them searches for that hero's changes. The blue arrows allow you to scroll the hero and item lists. To search for patches, simply start typing a number and the suggestions starting with that item will show up.
