As
seen on DotA-Allstars.com, this
new DotA patcher has been released to replace your standard launching mechanism. Personally, I think it should be called DotA Launcher.
Here's what it says on their website:

Features
- Automatically downloads new versions of DotA and displays the changelog!
- Replaces the Warcraft III Icon on your desktop.
- Options to select additional programs (such as ListChecker) to run with Warcraft III.
- Run any combination of programs, (GGC, Banlist, LC, etc) in any order, automatically.
- Displays the latest news from DotA-Allstars.com!
