They also mention that the app just got another update, to version 2.2.25, and all of the release notes are posted over on their site. They're also looking for help -- if you're a C# developer, or know one who can work on their rogue and hunter models, be sure to let them know. Since the program is open source, anybody who knows the code can jump in and add their own features, or fine-tune the class choices, which then helps out everyone who uses the software. Rawr is definitely an excellent resource for anyone looking to get their gear perfected -- it's a free download for Windows on their site right now.
Update: Since this post was written, the app has been updated to 2.2.27. That was fast!
